Circular Marble Machine? - Design Review �� #2

the sign

review the favorite engineering design

show of the people in the universe i'm

here with my friend sir 3k and we are

going to go through your suggestions

that you have sent in to the mark

machine 3 project i'm very excited this

was super fun we did it last friday and

now with so many suggestions we're going

to do it again let's get straight into

it but first how are you today sir 3k

simply simply brilliant this is a

favorite of mine just going through all

the awesome stuff that you the viewers

have sent in it's so nice to have this

communication with you let's see if

there's any good suggestions

since last week then yep

so

um

let's first start with a b program

switch so you got my keyboard now you're

in control my friend and do we have a

chapter soundboard sound

[Music]

[Laughter]

let's ask a little thing is there a red

line going out in the stream or am i

just seeing a red line in our obs can

you click that away inside obs

sir 3k just click somewhere okay we're

good we're golden everyone

a b program switch this is the solutions

that are about making

one programming wheel play two pieces of

music that we've been talking a lot

about

so

we start strong with 30 degree

revolution steps from alexandros this

shows how we can use

less rotation

and still get all action so this is

actually

a very very good image alexandros

i love it

and we're starting hot and good with

design and also

let's see yeah there we go a nice little

super chat just came in there supporting

us from robert james i wake up dreaming

of marble machines today martin will

become doc ock creating arms that can

play more instruments than humanly

possible thanks for sharing the joy of

invention thank you so much robert that

means the world to us that support

thank you so much and it's interesting

because i just for the first time in my

life read the word doc

so if you go over to the design

requirement documents i don't know

what doc oh now i know why doctor

octopus okay go over to maine so here

are robert james the same person

who is writing uh here about like doc

oak's arm so i just saw your suggestion

in the design requirement before the

stream rover so thanks for that and i

have to learn what doc is let's get back

to the designs

uh

so

uh cam

muting lever

okay so this is

also for the a b program switch

and this is exactly how we're thinking

about it

to have this is a great sketch by

antoine

and

this

shows that when you pull it

the blue cable will pull and when you

push it

the red cable will pull this is

important because cables are not good at

pushing but we want to pull

in both directions so antoine has it

completely right and antoine is even

putting it into the same bowden cable

which could be very interesting love the

sketch

monster switch a b muting feature from

david charlie

um

i think that for this feature it's

better to restart thinking from the

beginning you put in the design

requirement a statement how do with this

in mind i think if you design correct

you could achieve the goal without any

supplementary you can take a look

yeah so i think um

um

what david has fixed here is how to have

kind of individual and master switches

and we have to look into the boeing

controls and it's kind of funny i always

joke that sir 3k has only on off there's

like no dynamics either we go for

something and then it's a full bowing

throttle like so

basically every decision you make you

you break off the throttle and you throw

it out of the airplane window oh so you

want me to change something well then

i'll change it for real more

i'm like in the color grade and the

video is a little bit dark and what i

get back is digital white image yeah and

i just want to say from mandrakeel here

hello i hope you have a great day

everyone greets from switzerland now

mandrake has been uh

brilliant with suggesting stuff in the

past so i just want to give her the

shout out here thanks for him

famous for the mandrel

module

so i didn't know you are from

switzerland they have great mechanical

engineers

okay poor a is missing its quick switch

to a b

so this is a suggestion from duker that

says that i have to step over two states

for the muting so when we have program a

i want to make a quick switch

to program a b

we still don't know if we're gonna use

program a b

um

so i actually have to make um we don't

have to show that i'm just going to

right here a b question mark

so this is true and i've actually sneak

peeked that there's a solution on this

later in in the ideas

crank brake cables ball bearings with

springs to hold the crank in place at

the positions corresponding to a b so

this is a great suggestion

um

with

to make

you know on the original machine i had

this by stable mechanism

um

i can't show it right now it doesn't

matter

or i can show you you can are good

so the levers to the right

click into on or off

and this solution if we go back to to

the sketch

is about um

giving us three points

so

the lever always end up in the correct

position and i like it so it's it's a

great idea something like this should be

used like spring-loaded ball detents

like i did for the hyatt machine on the

machine x basically yeah you were

laughing about something i just saw a

comment then it got removed so i can't

show it okay

there's something about okay people

let's keep it short

martin doesn't like to read

not that long

because it's not curved it will half hit

on the extreme positions you should make

it in consent and arc concentric with

the programming wheel interesting

because this was a discussion we had

when we did the thing

and the fact is that the diameter is so

huge

so the curvature is so little and i

think we calculated the difference to

0.1 millimeter or something like that

so when you check it in cad

um

this

it doesn't matter because it only moves

um 20 millimeter and the programming pin

curvature yeah the the wheel is so big

so it it doesn't matter but you're right

that there is a difference

from gusty

let's see twist to mute

a or b

[Music]

less parts each to manufacture no

troubles with the bowden cable

so gusty

so

okay

so this is an idea for how to

do different instrument groups what is

missing in this id agustin is that we

have at least five

probably six individual groups

so your sketch has only two

so when you start to put in five or six

of these next to each other

you will run out of space quite quick

and

if i see it correctly

um

and the genius thing with going into the

middle to twist them is that everything

can be on one axle so for in your design

you would need like six different axles

and the pivots would pivot on different

parts of the links you can already see

it on the closest one that you're

pivoting further back which means that

every link has to have an individual

design

so it's actually

kind of harder to manufacture i think

because you they're not

one one design tenant that i think we

should uh hold to in the market machine

three process

is to have modules that can be repeated

and it's the same part everywhere

and this wouldn't require custom parts

plus the fact that here the levers has

to be physically connected at exactly

the orange

rectangular block point

so with the powering cable we can put

the levers anywhere

but um still i think your suggestion

would definitely work but i still think

mounting cable is simpler

so here we have the muting and this is a

video i think which is really nice

and they put if we see they put the a b

state on both sides so there was a slide

before saying there's no a b state

on a quick state

this is beautifully um

beautifully made in fusion 360 with i

think what is it called

contact sets

i love these animations when you're down

you're you have this person who is it

from

sadly i don't see it here anyway golden

star gretzky hall of fame brilliant

because uh this person have done

downloaded the latest cad from our

website animated something that helps me

think very very appreciated beautiful

and this looks maybe like it's from the

same person

uh oh yeah it's the same

it's the same design it's brilliant

inside cam for car handbrake lever to

engage with to push either to a

or b

inside cam for car handbrake

so

where

i don't really understand where on the

machine this would sit and if it's

connected to the shaft of the cam or if

it's a bowden cable

jack haynesworth i mean this is beauty

it's a beauty if the monster lever has a

large range of motion

larger range of motion than the separate

levers and the spring to return to

center

it will not get in the way of the other

levers

yeah so so the the point here is that

the master lever

has to

when i want to individually switch

program for the bass

or mute the bass

the monster lever can't obstruct that so

this is just a great clarification of

that

gear cable axle okay so

here we come to the

thing that

a cable can't really push

perhaps a hydraulic

uh

bounding cable could and

i have

lined up for our next live stream we're

going to discuss about in cables

and i don't know how a hydraulic

bounding cable work and i don't know how

how expensive it is so this idea would

perhaps work with a hydraulic cable but

i wouldn't have it work with a metal

cable inside a bowden cable because on a

bike

brake the thing that makes the cable

return is like a spring that pulls the

cable

so you should always pull a cable and

not push with it

and we have from bokom good day gents

nothing like a cup of coffee and vintage

between struggling miserably with my

projects

we hear you we can all like relate yeah

we can all sit together in this right we

can support each other in the misery

welcome and i can relate uh good luck

like

i think the worst part of struggling is

when i feel that i don't really know

what i'm doing or if it's good like the

work so

my only advice to you is like to dare

there to

dare to try to take different

perspectives i've been too slow on that

in my projects but there to see like the

truth uh from the outside

um

because i think like struggling when we

feel that we are working on something

that we believe in is one way but

struggling on something that we have

lost hope in that is uh that that's hard

so i hope you find your northern star

yeah in your project but know that we're

all in this together

love it we're here for you as well yes

thanks for being here with us so jacob

has sent

um

this is also really a b switch

um based on the flat face makes unmuted

state more stable image in stream 23 you

correctly said that the sign would fall

in place but this design would not make

it fall flat faces makes unmuted state

more stable

constant radius from rotation axis to

add stability to contact surface

ah

this is cool

so

the idea here with jacob

um so j and i love this so jacob is

iterating

maybe on on the maybe jacob suggested

this design in the first place but

instead of having a thin tip

it's just a broader tip but the tip has

still a radius

so that there is no falling falling

thing

[Music]

it's a nice

it's a nice suggestion to make a

camshaft

but my other

it just looks more solid basically than

than a pointed tip of the cam so super

super cool iteration

two independent shafts that can shift

any of the four position with one action

using a car stick shifter

james held

healed

two pivots

over one to me just feels like more

parts like it's cool but i don't really

understand

i don't really understand how it would

work um it's probably because i don't

know the car shift

thing

and i think if i think of a gearbox of a

car you have to kind of think about what

you put in

and i think

to have one lever to just go back and

forward and rotate two different ways

i think

it's so easy program a towards me mute

middle program b all the way forward i

can go immediately from b to a

i can go immediately from a to middle i

can go immediately from b to middle

it just feels more more straightforward

a bigger radius enables different states

to be closer this is a super good um

point here

that has been made

so what i mean with closer here is that

you can see the blue and the green line

the angle is less which means that on

the right side we need less rotation we

need less travel of the bowden cable

awesome illustration drop ball to mute

springs to center lever

yeah so this is the same that we need

the tri-stable position

and it's a spring-loaded ball

that clicks in place and we here we're

using four steps and this user have

correctly put a b question mark and if

we go to my ipad

a little quick yeah you can see

gretzky in the in the suggestion

so av is a big question mark i honestly

do not think that we're gonna allow the

a b state

um and this is actually let's let's go

back to the sketch pad a little quick

um this is what we call a known

unknown

um and this is the topic of the next

stream

um

this is a known unknown that we have to

deal with

a b state uh

if someone doesn't know what it is let

me make a quick demo on the keyboard

so

i showed several times before

um

let's see let's see if we have it there

we have it i can fix it

all these setups

we are ambitious here so i showed

several times that we have program a is

minor

and program b is major

[Music]

and the a b state

would allow

one channel to play both at the same

time

so um in this particular song it would

be

it would be the jimi hendrix chord

[Music]

um

like um

c minor seven

now how do you play it on guitar you

play it actually like this

[Music]

that's more your mandrakes

does it sound like hendrix oh yeah

but the only reason

so actually let's let's let's make a

decision right now i want to skip the a

b state actually because the only reason

to have an a b state

would be

if the registrators are slower than the

ball drop which i don't think they are

that would allow one channel to play

faster so it has with note repeatability

to do

but mixing the two programmings

like like here

to play both at the same time

i just don't think i want i will ever

need that tool because

we're still limited by how often the

marble can drop

so

it's not like we automatically can just

play twice as fast all of a sudden just

because we input

rather it can be really really tricky

because it can mean a lot of half hits

so i'm just going to make a decision

right now

let's go to the design requirement

document

and let's forever forget about the a b

state or maybe or for now anyway i just

want to read something uh nice here from

katarina oswaldova

the feeling of community i get from this

stream compares to nothing together with

the lovely spring weather it almost

makes me forget i have a mid-term later

today

wow thank you catherine and good luck on

your mid-term yeah we're rooting for you

glad to have you here thanks for the

great vibes

it's i'm touched i'm so touched like by

people going into the documents and

sharing their vast knowledge

and now when we're working on a digital

model we can really work together so

this is the design requirements document

and i've been educated by this wonderful

community on how to write one and i do

have

um

i think it's high time to include what

we're talking about here um

so

is this

program here program switch

but in chapter five

it's so high levels i'm not gonna write

it here

but i'm going to make a design

requirement under

um under

six here

kick drum requirements

oh here we have it

rafael rudini stark the thing is would

it be useful or one more thing to go

wrong super good comment rafael it's

exactly

what this is actually like the machine

is going to be complicated enough the

program switching a b already requires a

full-size vibraphone to have 174

registrators or something like that and

i think just that we've taken enough on

our plate we have to kill some dartings

so

um

i'm going to now do make this a little

more more official this design

requirement right here

[Music]

so i'm going to make a headline

but you could go

um let's see

program

a b

program a b

switch

there must be

three

program states

program states

and i'm gonna say state one

um

which is going to be

pulled towards me

[Laughter]

einhorst hashtag team rethink

a b

state one

playing

program a

a b is a darling that we should

collectively kill from this very moment

any more a b idea turn dark

[Laughter]

um

so let's see here playing program a

state 2

muting

muted

muted

off

state 3

3

playing

program b

it doesn't that sound simple

don't say it from sandor you hush

i think a b would be a nice feature but

it also it could be easily added later

with minimal changes so no need to push

it now

beautiful

gears in your profile picture sandra i

see them

tell tell us why tell us how you would

use the feature because as far as i know

it's impossible the a b feature is

currently impossible

or rather it's

because the marbles the marble gates

can't handle it

they're too slow

for the added speed but if you have if i

missed something with it please tell us

like how you would like to use it adrian

shaw is uh more straightforward here

playing a b seems pointless you're only

considering it because it's easy to

implement yeah

that's how i feel about it

so um

so now we have

actually an official

in the official design requirements

there is no mention of a b which means

um we should try to go for

things that have been unsolved let's go

back to the design uh suggestions but

first

life is good because look who just

joined in here slice of sparta we're

reviewing the signs we're praying on

noise martin is the man hk h3k brings

joy love the progress so far keep it up

cheers guys

cheers to you as well sparta for always

bringing it with your wonderful support

thank you so much so much

okay i am have the this one here we go

um

i have to can you make

okay the grids hold everything in place

sadly i can't enlarge it for you my

friend dark red calm touching only red

prog a

a-rod

okay so now i now i see your suggestion

by renat cool idea however

um the genius

of the marble machine exercise was that

this link

all these red and green ones were only

resting because of gravity

which means that it can be pushed up by

by the action so if the levers are

resting inside the grid

because it looks like you're pushing

them down

and then they can't they can't

in the edge cases

they

they can't

basically when you unmute exactly when

there is a

the edge case when you unmute exactly

when a programming pin has activated a

thing

it will get stuck i think in your design

because it can't swivel because you're

pushing it down with the grids

so i think

um

and i think also it's more difficult to

make this ups and down plus

when we want five instrument groups

there is no space between the instrument

group so we need to access it from the

middle

and for your grids to keep together it

needs the side walls and that space does

not does not exist

i think actually your solution

if if you only if you if you remove this

things on top and on the side and if you

only pushed from below with your grid

idea

slide

up and down

this solution would actually work

equally well as the camshaft

and

but i think

it's harder to make one lever movement

have three states

because the rotation

gives us the three states because

otherwise i would have to pull the lever

one thing has to come down

and then another thing has to another

thing has to slide up

so

so far i think the camshaft is um easier

but i think it would work if we remove

the if we remove the ceiling muting

channels a b combined with one input

a b a b

[Music]

separate with two inputs

not

so here's a b still in but it was in

when you sent this suggestion so i

understand that

um

so there's two levers for a b

[Music]

i think the one we have is simpler

front view of master

lever

put the bars inside of the levers

slide side view of other levers

okay this is a suggestion to make the

master lever a little bit more

beautiful

and

yeah i like this i like this idea

um

do you do you understand it honest i i

guess i can sketch it okay maybe you

maybe understand it i understand it okay

i'll sketch it for the viewers okay

um

do a quick one

five levers

these are the instrument levers

and the monster lever

and instead of having this

arms like this

the suggestion is to to make the arms in

here yep

and that would leave

that would look more magic because it

would be okay there's only six lever but

the last one is moving all of them i

love it cool cool cool only thing is

that the muscle level has to be chunky

because it's gonna take a lot of time

let's

see the next design good idea

woohoo a gearbox

wow the shift plate

base kick

this is basically exactly what we're

gonna build however the the steps

will be

the extra this when

from spraying the machines i don't have

time to do this because to think forward

and then to decide

it's too many operations only forward

that's the way to go

but beautiful sketch

valden

muting systems

[Music]

alexandros only a both a plus b

both mute only b

[Music]

so

i see what you did here but both a and b

are gone

so we don't we don't need the solution

this one we saw already probably

suggested in two

categories pull pull on both sides this

is exactly how i'm planning to to do

this

many state camshaft unmuted or muted so

too many options

beautiful sketches again

big lever

and here's also the issue

with this system is without um

mounting cables is that you can't do it

for five individual um

instrument groups it looks great for one

but for five individual is

so why use powder and cable all it does

is move lever location cable is great

tool for marble gates but when you have

a hammer

everything looks like a nail

yeah so so

your lever the bowden cables can enter

in the middle of the shaft so imagine

you have one instrument group on the on

the first five centimeters and another

on the next five centimeters the bowden

cables enters in the middle like this

and requires no sideways thing so your

lever on the side

the way i did it on the original machine

i did a pipe in pipe muting system which

was super complicated so i had five

levers around the same

axle and i don't want to redo that for

this machine so

um

it's true for one instrument but

um

how would you

how would you do it

um

how would you do it for five groups

i think your argument would be better if

you said to use a cam link

so if we

by having a link that just goes on one

side of the cam you can not rotate it

more than 180 degrees hardly 180

so just a stiff mechanical link

and that could be flared out

to different levels on another point

like this

so we can have like one two three four

five levels on these flarings things and

then you can access different

instrument groups

um

i do

like the

impression expression when you have a

hammer everything looks like a nail

that's brilliant i'm in favor of the

boat and cable still though next design

next a sign

uh spring detents on these levers yes

that's what we should do

hard stops on this lever

so why is it hard stops on the fourth

lever

all

move the all lever all over to where you

wish

then pull the lever to its right to

squeezed upper and lower

okay

two actions

instead of one i do not have time

when i play the music beautiful sketch

though

two registrators to one boat and cable

we we looked at this one actually by

gusting

um

i think this is a video right yeah so

this is perfect this is the

spring-loaded detent idea and extra

points

to mike perry

gretzky in the chat

mike perry extra points for only

including three states because we do not

have the fourth state anymore beautiful

animation i love when you send short

animations those are the favorite

play a mute both play b play both okay

beautiful sketch with the yellow but we

have removed the play both state

mute both same here

love the sketches and this one we saw

this is the mc throttle

and the wheel

spring tension bar guided by a housing

channel on each lever with granulations

for indexing it

ha

so this puts the indexing a little bit

further out which i kind of like

sorry for the long text here's a bonus

condor

wow with sound

i was thinking that mute all instruments

at the same time is not worthy by

using the individual levers through a

master lever you would need to rise and

lower the shaft that support the levers

of the registrators for two important

reasons

first by triggering the master lever you

can mute all instruments at the same

time but you cannot return to the

previous configuration this is true so

what is

what the designer means here is that

if we have a special setting like a aabb

and i mute all

wait mute all

which is also interesting from aabb

wouldn't require two more two movements

first

no that would be chick chick okay sorry

nothing

um

this is

by rising or lowering the shaft you can

return to the same

i'm not sure i'm understanding this idea

spring tension bar

guided by a housing

do you understand

no no no sadly

it will be always all instrumental mute

all in channel one on chantu and in by

rising or lowering the shaft you can

return to the same configuration of

channels

per instrument before muting and not to

have

reset all instrument individually every

time you use it

in mechanical terms i think it's more

simple to lower and rise the shaft

that a complex master lever

now i know what's intended

let me sketch what this suggestion is so

everyone because i i

now i know now i know what you mean

um

so

we all know what this is

and we all know what this is

this is our camps

and

very simply

mute all

is just moving this whole thing straight

down it's not a rotational thing

and it's actually a genius

point that has been made here that if we

do that the rotation of this

will stay

intact um

however i do

not think

this is worth to implement it because

moving a one and a half meter long thing

even two centimeters down requires a lot

of infrastructure here

and a spring to make it return to the

exact same place and everything

very very doable but i think

we have to think about what function it

gives us

and

i think the idea to have to

so what would it give us it would give

us like i put i put like the bass on i

have the bass and the snare drum on i

have everything else off

this makes it possible for me to mute

everything

and then put the bass and the snare drum

on again

uh memplexes something like this here by

using a master lever you put all

channels in mute after you have to put

each instrument in a new state

individually yeah this is exactly um

this is exactly the issue that the

designer has solved here

by um by moving so i i should make these

sketches into a better

let me try something right here

so if i'm

if i do this

and then here i can actually move this

oh

cool huh wow i discovered there's layers

in this app

there's layers to reality so

mute all would be done like this

hmm

i mean i mean it's it's a cool

[Music]

the cool thing about it

is i've been thinking about something

the mute all lever

will require a lot of force

because it will it need to stretch

all the bounding cables

which is kind of like five times five

ten

and by doing this instead you don't do

that

you're just flexing the bowden cables

let's marinate on this a little bit um

next design

so so

so

how would i make the shaft stay down

that's just something

yeah let's first before we before we

leave this one because this is an

important question let's first go to the

design requirement and make um

mute all instrument levers lever

[Music]

design

drop

camshaft

down

or switch

all channels

so anything that is not design agnostic

these are the sign note

i'm going to make everyone crazy in the

design requirement by doing the sign

commands in the document

there are they are to be taken out later

so everything in italic and in

parenthesis

is not part of the design requirements

so thanks for the suggestion it really

made me think love it i don't know what

this means but it sounds cool

why not a hydraulic manifold under the

arm yeah that's probably solving solving

this so cool

let's go to the next

it's a spring-loaded bar there okay yeah

this is

and thank you so much for the condor

can we get the sound

oh

next design

pause with lowering the shaft and all

mute as a cam state from me lupilo

yes lowering the shaft oh yeah okay

pause with lowering the shot and then it

would go up again yeah

i still have something in my stomach

about moving that whole shaft around

it's like oh

because all the bowing cables wouldn't

need to move it's a whole huge platform

thing and in music you want things to be

you i'm going to show you how much time

are you ready i'm going to show you how

much time you have that much oh wow

whoa

next design

yeah you're the one in control my friend

was waiting for you all the time sorry

everyone i was waiting for that guy over

there that was actually me

the shape

t rotation of the red lift different

connectors based on angle of rod use

detent to give feedback on rotation

yep

to determine the mutant state of what is

playing use a machine rod that is shaped

such this rotation determines whether a

b is muted totally agree we can

manufacture the same thing and put them

in alternate pattern great suggestion

drive train everyone my favorite topic

uh it's actually i don't know i just

said that i don't know why i said that

rhythm programming wheel belt mainframe

with this configuration

plus for using a whiteboard love that i

also love the message at the bottom

oh from francesco

um with this configuration if the belt

breaks it will not be changeable

being a loop

oh yeah it's a metal beam we remove that

metal beam

the belt lowers the weight

that should keep the wheel in its place

oh this is true the belt is lifting the

wheel i didn't think of that

this shouldn't be a problem but i just

wanted to point it out good one

francesco i didn't think of that the

belt is actually trying to lift the

wheel out of the bike fork

good point

it's recorded in here forever and ever

thank you for that

roll of speed hub on mmx3 so

i've seen several from magnus sirens and

i've seen several suggestions to use

like these off-the-shelf gearboxes and

what i don't like with these ideas i

don't like to drive a huge wheel from

the center axle because the

leverage that is needed

is monstrous so if you have a small

gearbox that has to drive a huge wheel

from the middle

i just don't think it's made for that um

and i don't think

it has

the position will be as accurate so a

little slack in the little gear in there

will result

and a lot of movement on the sir on the

outer perimeter of the circle that's why

i tend towards using the large gears to

drive these big wheels from the outside

or the timing belt is the same thing

but it sounds cool the role of speed hub

is an epicyclic internal hub gear for

bicycles

and also we do not need to change gear

we only want one gear of the wheel

my thing is not working anymore

it's not working anymore no

give me a second then let's see yeah

it's working no

wait don't click around okay sorry stop

with the clicking

no stop with your clicking

please my friend

now we can click forward once

and before you go

further into that i just

in the chat today i see a lot of new uh

people who are commenting which tells me

that there are perhaps new viewers that

are tuning in and you know what don't

forget to subscribe to this channel so

you get all notifications about these

streams and also like this video it

helps us a lot

wonderful wonderful on this channel

we're doing the design work on our main

channel we're doing weekly summary

studies

between eight and nine minutes long

vibraphone but here we come to the fun

part instrument placement

yeah yeah

um

vibraphone in a circular pattern plunger

gears central shaft drums programming

drum bass so the circular idea

archimedes crew for marblelift by

feudery the circular idea

is very popular and honestly i'm so

happy to see all these sketches because

right now

i have no idea

on how to build this machine right now i

don't even think i can build this

machine because i realize that the

footprint is a big problem

it's really fun to see outside the box

ideas

what's this

side view

oh yeah this this is a very simple but

genius idea to put the marble gates

under the vibraphone for the drums

um from a warner

it's a great sketch and i heard the idea

before so to avoid mid-air collisions

uh we we could do this

i think the machine would be quite high

but it's it's it's a good way to get

more room oh wow here we go

mega prr has made the most epic uh

comparison between module design and all

in one design and this is exactly where

my head is so i love to see some input

on this and there's a lot of text but i

think there's a lot of work been thought

behind here so let's start modular

design versus all in one design

on the modular side no sound bleed over

high instrument visibility easier to

make

think midi virtual instrument plugins

but real

and then we have a little um

graph thank you

multiple modules makes it a lot harder

to fail as it stops being an all or

nothing project

if a module doesn't work

at worst all you've lost is the time

effort towards it as you don't need to

throw out all the others

so to the left you can see

the different modules being finished

project is also future proof instead of

touring same thing every time you can

switch things up create new ones between

tours or upgrade old ones you're less

happy with

[Music]

so at blue line oh no big vibe module

fail back to drawing board it's not so

bad

and if you want to stop you still have

all the ones that work to continue

making music it's

super interesting to hear your thoughts

about this

so let's look at the all-in-one design

to the right space is limited more

confusing to look at

it sounds like mega pr is very biased

towards the modular design i love it

novel and visually interesting but

unchanging from tour to tour if

successful you get to preserve dna and

get satisfaction of getting back

at a machine that won boxing match twice

worth it's a question mark if marvel

machine 3 is scrapped consider a fresh

start with a modular design it's a

radical idea but maybe a good music

tinkering balance

and let's let's look here at the last

graph

i just big big big love for for for this

this work you put in mega prr mm3

finished single machine is cool but

risky

it's an all or nothing deal as we saw

with mmx stressed martin at the bottom

there and then we go up and then we go

up and then we go down stressed martin

again that was me last autumn i could

tell that was

that was me lost autumn

and trying again

burn out or give up

um

brilliant so

brilliant work media prr this is

actually like

1.4

upcoming live streams

um because this right now i don't feel i

have a machine i want to build and it's

because i'm lost between these two

two main ideas

the one to the

ralph

oh ralph is here

so ralph i love your sketches and you

you made me think a lot about the craft

work um

the bandcraft i get a ban craftwork feel

from from your sketch ralph love to see

you here live i love your sketch and

it's also given me a little bit of an i

the machine a little bit of an identity

crisis because

form from function

would go for the modular design instead

of the all-in-one design

making smaller modules makes marble

hunting easier because of less marbles

from ralph yes

definitely agree

and um

yeah

this is going to be the big battlefield

in in the upcoming week

because

this is the only thing i'm thinking of

right now this super high level decision

is it still fun is it still a marvel

machine or have we have we pivoted into

a completely new project so love love to

get all your thoughts about this

next design um

so this is a circular design again

some um the vibra plates are a bit too

far on this image yeah so this is the

circular pattern but you divide them out

so you don't have any mid-air collisions

illustration by eddie 171

almost vertical bass person playing the

bass

so the circular design is so popular

yeah it's

it's getting a lot of traction out there

yeah

out there

drop point flight path capture point

rotate the bars 45 degrees along the

axis

resonator should not interfere and will

not have

mid air collisions marbles can route to

the rear of the machine only downside i

can see slightly wider separation of

bars

but you can keep the normal layout for

manual play

drop point is green flight path

so it's angled to the side

tricky

how the the vibrato shaft that goes

through all the resonators is one

straight shaft

how do we build the vibrato shaft

that's the that's the trickiest thing

with this design

here is i think from consonator right

this is gone

and programming module control panel

bass drums vibrophone cycle power module

or seat the worst thing is that gonzo is

right here cycling the tempo would be

one of the easiest way to feed the tempo

perfectly

sometimes at the gym i do like this

cross trainer in time with the music i

try to put the one handle on the snare

drum

and i think actually this would work but

it's too much circus exchangeable

vibraphone section

including note plate and resonator pipes

and we have a comment from warlion

wintergatan with a modular design is

gonna remind me big of any music setups

smiley face all we need are the lasers

yeah the modular design is it's another

thing

it might be less interesting it might be

better music and definitely better sound

the modular design allows us to separate

the drums away from the vibrophone which

will be

wonderful martin

here's a beautiful comment for you

svenska disc golfer

so uh this is cool so

swedish disc golf uh

society send some strange to find the

best solutions from the entire swedish

disc golf community i um competed at

national level in par sm once

for slotskogen disc golf club and i was

eaten like the goat in jurassic park by

these uh players i i think i had a

single match against someone who took a

european championship silver

and it's super fun i and this golf er is

just the best sport of all so super fun

to see you here so nice swedish disc

golf ss

society

exchangeable very fun section um

my mental game and this golf was not

good i could do good on practice and if

i did well in a competition round i just

um

i just

got locked up after half the round and

throw through the disc into the forest

okay so this is a mandrakil module

exchangeable of our phone section

including node plates and resonator

pipes gets dropped in replace with every

song gets prepared as programming wheels

are prepared too with simple sliding

mechanism clearance to other components

when being exchanged need to be checked

just a big box by handing

this

is a super good idea

man this is what we call the mandrake

module

let me uh hang on i'm going to

um

find

not yet but i am going to find

our decision matrix

some of you might have seen it

let me

so it's of course in here

so here we go um

your solution

are all these um see if i can get it a

little bit bigger yeah

like that

so this solution is referring to all

these mandrake module um things here

um

so and they're not circular

and when when we did this

i tried to make my biased solutions win

but your the the thing you suggested

gets got a lot of points in the test i'm

gonna drag it over so we can see the

total

so there was a kind quite

much more of a close call than i thought

so judging from the decision matrix that

we used

if we go back to the idea your idea is

really strong

and

if we go for an all-in machine

i think we have to use this idea

the mandrel module

uh and henning had the same idea except

independently from mandrake so

it just hurts me to think about it and

this is where i think the whole project

is pivoting right now like i want a

music instrument that can play

i want to make a real vibraphone with

full musical expressivity

but i think i've realized that i can't

have an all-in-one solution

with that design requirement so

if i decide no we want to beat the old

machine we want to make the classic look

then this is going to be

uh the solution

chat reminding me here

oh h3k we are in part two of the live

thank you

there we go thank you so much

thank you

um

let's take the next design i'm gonna

keep on going here

cool circular vibraphone

what's this

marble gate

oh yeah it's a funnel in front so you

catch them right away

ah

so

maybe

let me sketch on this a little bit

so i i've excluded this idea from my

head

and the reason i've excluded it is

because i thought that

it was

it's going to be visually too annoying

i thought about it like this

and i thought that the funnels would be

like this

but let's say

because we know that marbles

marbles doesn't bounce

really well

on on vibraphone so if we if we angle

them a lot

and if they only bounce like this

and then here it can bounce a lot

on the drum

the little catchers represented by blue

maybe it doesn't need to be that high

so here you still have good visibility

so

here is an eye

the eye if i draw a straight line from

the eye you can see the bounce you can

see the bounce you can see the bounce

and if we make sauron's tower here

or thank you

and we'll put a little frodo here

there we go there we have it love it

next design

uh boo boo sham bibo champ what about

making only the drum loop machine

separate that way the sole of the mm

microphone play can be focused on first

if the loop fails you can have a real

drummer take over

and it's not a bad idea

so here is a rotating stage for visual

impact wherever you're seated at arena

this is a beautiful model we feature

this in the thumbnail because i love

this model

it's so well

well put together as well

um

just the visual imprint impact of this

i mean it looks so cool i don't know how

it would work in reality but the look of

it is like oh

i really like how it looks yeah so when

you see this you're like well you just

you do that but there's no functionality

in this model yet so it's it's more

formed and function but look at this

it's beautiful

mike perry teaching me here in chat as

well of course it's baradur

thank you so much

we got our our looter

lore wrong

so thanks for sending these beautiful

very inspirational models

let's see what is this

height adjustable

input q built into component volume

cables allow these to be anywhere

angle adjustable for liability testing

uh

ball capture built into component

it's kind of the same idea as we had

before with the with catching the marble

right where the

instruments are

input variant from above

[Music]

um the bass can be the flywheel i think

consonator is referring to this

i have to run around like a squirrel

then i can power it like a squirrel

wheel then you can just run

get some cardio in on the on the concert

itself

fun to see you here gonzo

i'm engineer

marble divider marble lift

programming wheel vibraphone panel so

a lot of people love the vertical

programming wheel

but

this means that we will read

the program on different heights

and it just introduces like a whole new

i would say these vertical programming

wheels are kind of out of the questions

because

all the components would want to fall

down

alongside it and i just haven't thought

about how to make it

um but beautiful sketch vibrophone frame

marimba

have the ability uh to use the same

resonator pin but change the instrument

from viraphone

to marimba no i don't like sound of

marimbas it's the lion king uh no it's a

little mermaid

so um i'm only in it for the vibraphone

i don't like marimba or xylophone sound

at all

so

this

is

um

[Music]

thank you for the suggestion though

um

drum bass

keyboard vertical again right

yes it's a yeah it's a vertical

programming wheel i think it's too

difficult i would like to see that with

more uh like granular uh sketch so we

can see more about how it would work i i

don't see it working but maybe i'm just

stuck in my old ways

microphone placement to avoid mid air

while keeping full-range vibraphones

extra nodes slots for node repetitions

yes so the thing here is that

you have collisions everywhere in this

sketch because i want to use 40

millimeter

uh marbles so let's just take the first

chan the first white key up to the left

would um collide

with um the first gray gray key next to

it so the marbles are bigger than your

center to center distance here

um

but as i said in one of the

live streams i don't think this is a

problem because we will know exactly

what note interval has a collision so

for example a black key to white key

like this

can never

sorry that can collide

white key to black key can't

and if you want need to play this

in the exact rhythm where a collision is

so you know

we have perfect control over how where

the marble is because we have perfect

musical timing hopefully which means

that we will figure out and this is

maybe something we can do in physics

testing we will figure out the exact

timing interval when a collision can

happen

and basically we can make a list

in what bpms

we can't do a certain node repetition we

can know in theory

exactly how to avoid uh these collisions

so i think the collisions are kind of a

non-issue but it's a known issue and we

have to we have to deal with it

quick tip for procreate turn on pawn

reaction on the ipad and rest your hand

how mick you will on the shrimp turn on

palm rejection on the ipad linus t

coming in with the pro tips because the

the stupid thing always switched to

um

switch to

uh

eraser for me

and i can't make good sketches so

linus leaners i have to implement this

right away

palm rejection how do i do that then is

that a main setting on the ipad or is it

inappropriate can you google that sir 3k

of course i can yeah my friend can

i'll go on with the review austin

is suggesting a beetle space this is

exactly the same base as we had on the

first machine i do love the look on that

and it's more narrow as you as you say

so we need a sound note here

sir 3k link from pro to mormon thank you

i can't live without those

[Music]

let's see new chapter hello it's my idea

to simplify registrator

one that we have already start being so

complicated this one is easy to modify

and a small footprint

every part is independently mounted on

shaft gravity help to back red lever

to main position

muting is possible by rotating second

shaft

which block lever in standard position

manual lever as the red one is

independent and can be run in any time

about program switch to second song red

lever can be shifted along the shaft

with some extra handler greetings from

chris sutco

manual lever independent um

so the programming pin is coming

this is this is interesting

what is the green lever doing

oh that's a manual lever

if i want to play manually i think

um i'm not going to play the marbles

manually

on

so this actually uh reminds me that it's

an imp in important um

design requirement

to if we should be able to play the

manual

the marbles manual or not chad said you

missed one suggestion

from the organ guy but i don't know

yeah maybe it's not in the slide okay we

have to check that later

um

so

i think chris uh that your suggestion

falls apart because you're sliding

you're sliding the red thing along

um

along the axis and that will

be half hits and stuff like that so the

way we're now switching between program

a and b is the only way i think that

would work

um

but when i see your image i hoped it

would work i i don't think it will work

to switch between the programs let's

check the next sketch one bowden cable

enters

to leave

ratchet in input allow to flex out

as the input is pulled

the cog spins 90 degrees the lugs on the

cog pull on alternating outputs every

cycle

as the input is released it is allowed

to flex outwards to slip past

this is probably smart but it looks like

much more parts and much more

complicated parts than just

uh doing the mc throttle solution

loop drum beaters and a little chapter

marker please from circa thank you

i'm still here

alessio biancone

orange recoil spring container blue

programming drum gray actuator

exploded view of actuator and spring

container this should be mounted on a

fixed axis

actuator gets rotated by drum

actuator power can be programmed into

the drum positioning gear teeth

before the needed beat

ah

and cannot move the actuator

okay i'm i'm getting this id and i

actually have a new id regarding that so

we're going to take a detour here and i

want to sketch for everyone in the in

the do you want to try to add the rest

palm thing let's see if we can fix that

really quick okay

in your

in your ipad home settings the system

settings can you bring up the comment

again or is it gone

uh i can see if i can find it

so

home so let's not share that right now

uh home okay

so we're fixing so i can rest my palm

this is from what's from linus and i

it's been super annoying that i can't

rest my palm on it scroll down on your

apps until you find procreate

where do i start i mean

yeah there should be a procreate

somewhere

okay

trying to go slow here

so this would allow me to rest my palm

procreate yes and then there should be

some palm support fine mode or something

palm supports tm level

that must be it

disable palm support i had checked palm

support

fine mode palm support standard flying

mode i think

fine

no standard i think standard okay try it

that way let's try

i will switch over now

oh yeah you can switch over so now i'm

resting my palm on the sketch pad and

nothing is changing oh this was the best

tip ever thank you line

maybe i can show it without pulling out

the cable

uh i can now like have my palm smudging

the surface and still draw

oh yes

glory

thank you so much for that tip oh

changed my life

and

perfect now when we're also going to

sketch for this uh thing so and also

just quickly another little ding ding

ding there

from jimmy crosby wonderful and

musicians

good luck with the guitar playing yeah

thank you for your wonderful support

this means the world to us or is it the

bass guitar maybe so cyberbase

go back to the last suggestion so i get

everyone on board here because this is i

think this is riveting because this

has never been done as far as i know in

the history of mechanical music

and this is another technique that i'm

not

thinking about implementing but alessio

bianconer

have

given me a new way of doing it i think i

have an even better way that i like

figured out yesterday so let's go to the

sketch pad and let's figure this out

so this is the old problem about the

spring loaded

beaters so here's the programming loop

and here we have the

programs

coming down like this

and here's the pivot and here's the

reader

and here is the drumstick

um

and of course there's a spring here

so

[Music]

um know what let me try to add

the pivot in a second layer so i can

rotate it

wouldn't that be something

we got even more

ipad pro create tips here something you

could think about

make sure to turn off apple pencil

double tap so you don't switch to eraser

mode on accident oh that was

so and

maybe you can research where i do that

of course i can oh no this went wrong

so as you know

this thing

can i rotate it rotates like this

kind of

tick tick tick tick tick tick tick tick

tick

and the

um

yeah i have it now okay i'll take it

later

because i'm if otherwise it's hard for

the viewer to follow if i'm if i'm

interrupting um

no

i'm in the wrong place

this

is not for this

this idea is for

um

using

this was actually from idea from paper

roll

when we were talking about paper rolls

so here's a paper roll with hulls

and it doesn't have a lot of

force you don't want to use a lot of

force or the programming drum it can be

used for as well

and we talked about pre-loading this

orange

drum thing so let's just make the drum

here

there's the drum

so

how do we pre-load um

i'm going to make a red

drum beater

here

which has been preloaded

with a spring force

and here it has been locked into some

kind of

latch here

so you can only you can pull out

this latch

pull out latch

equals boom

it plays

and the problem was how to make this

preload

but not make the preload exactly

when the stick is

going down

orange to make a boom

boom

and um

in alessandro's idea

that is made

by introducing

gears

uh here on the wheel if i understand it

correctly

so first you have a pin

and then you have a gear

so you put the you you put the gear

exactly after the pin

which means that

on the pin is probably here

which means that the thing is

going up gets released and then

it's returned

pre-loaded again

but my idea

it's a little hard to explain this i

hope you can follow

is

is

to have

no palm rest on my keyboard

again

but look at this

what do we have

in a programming wheel that happens once

per every note

we have a programming pin

[Music]

so my idea

prog

prog pin

my idea is to

um

read here

read here

and then

use the pin

with another pivot to recharge

here afterwards reload

here

which means that

let me take like some new color purple

this reading here

would pull out the latch

and this reading here

would reload the thing

my sketch sucks

hard

but

the solution doesn't suck

i hope i made myself clear did i yeah

you explained this to me prior but i

think

i think the audience will get it let's

see what chad says

let me make a custom because i think

this is okay another one i think this is

important this has never been done what

i what i know

in history

of music so

red programming pin

is

the read

read the music program

this goes to a latch

let's pull this way

[Music]

release

release

which means

uh that

the stick

uh sorry

i run out of space all the time why why

do i run out of space

the stick makes a boom

uh

afterwards the same programming pin

becomes orange

and it's red again

so we create um

we create another mechanical movement

and this is reload

reload

which means that the stick

goes up in tension again

because

we only the thing is that we only want

the reload to happen

when the release is not playing

and this would just

this was just make always always the

same rhythm play and reload

play and reload play reload play reload

and this would make it possible to have

spring powered drums

reloaded by the same pin that is

actually playing the note

i think it's pretty cool and

quite a fun tangent for a solution that

we're not even planning on using

let's go to the next design everyone

so thanks for this lsu it's it's

brilliant uh i think my version of your

same idea is uh slightly simpler and i

love the coil spring though that's a

beauty

oh any music our favorites this we

already saw this is uh

june

brown june brown drum causes shaft to

rotate

uh spring stores rotational energy

because of positive stop drive side of

shaft release and cause his whole arm to

rotate back the other way arm over

rotates

and boom stick hits drum arm returns to

rest position

okay so it over rotates angle to taste

flexible grip boom stick

i love the term boomstick boomstick

this

is my boomstick it looks greater arm

returns to address position via spring

and positive stop combo not

i'm wondering what the difference is

here between normal spring

oh that's a pivot

uh robert towel so the drums aren't

going to be played via marbles the idea

is to have the loop drum let's go to

cad so i can show that

um

so uh robert

the drums are played both by this lower

wheel in a loop that goes

um

with 16 beats

and by marbles from the big wheel that

goes 64 bits so basically what you can

do

um in this design in a way is that you

can do a

loop of the drum

but then you can add marbles

that fill in there was the marbles yeah

so both is the answer

next design

um

silicon rubber grip for a more natural

hit that's a little cool to to

mimic a human hand still snug in the

middle could possibly be tight and more

in the middle via a large set screw

bonus sticks are easily swappable

replaceable

interesting they will give a more human

touch and sound perhaps it's a nice one

only one spring for both directions so

this is the same idea as alexandre had

alessandro

with the coiled spring here

alessio alessio yes alessio biancone

to have a

torsion spring or a coil spring instead

of an extant two extension springs

um

it's interesting

problems with current drum beaters and

the desire to play dynamics by peter

o'neil

sounds like a little essay i love it

when only partially muted to play quiet

spring tension is less actuator level

hits less on programming heal thing

drumstick starts further away

these added together will cause for very

drastically different timing

you're absolutely right other solutions

that will not work due to changes in

release timing suggested in my own head

and by others on the stream adjustable

length of registrating arm adjustable

height of spinning heels on programming

drum so

the adjustable height of spinning heels

on programming drum is my favorite

solution but i've also been thinking

what would it do to timing

so can i see what's written there under

us

no longer same piece of metal as

registrator unfortunately i don't have a

way to make this yet but maybe better

minds can get there so i love the

humility of pointing out errors but also

um

acknowledging

that you don't have a better solution

it's i love that humility

somehow this angle needs to be

adjustable only by moving the starting

point of the registration arm this will

keep the starting point of the drum

stick fixed and the release point of the

registration arm fixed

only the tension from the amount of

pullback will change

i think this

is a brilliant um

brilliant comment um

i want to make a note on this comment

because this is something i've been

thinking about

so in the um

in the harry window or what it's called

with the known nouns and the known

unknowns

known

no nouns and the known unknowns

this is the topic for next stream we

have a couple of known unknowns and

dynamic

dynamic

boom sticks

as they're called nowadays

um

bad timing

this is like

this might be i'm happy you pointed it

out because this is something that we

have to deal with and think about

next design and lucas vandal is in the

chat well you can compensate for the

difference in timing of the different

height ramps depending on the way that

they are actually manufactured

great point lucas let's uh sketch that

because since we

will be able to know

exactly

so the idea

so

here

is the exact point

you would think that someone like lucas

being so smart have kind of a whole

instrument music mechanical musical

instrument museum to derive this kind of

deep knowledge from

so here is boom

[Laughter]

so

and this

is exactly

10 centimeters

from a certain point here

so then when we want to make the soft

note

the red triangle that is much lower

then we can uh

make this distance

seven centimeter

from this point and this point is the

timing point so we can actually learn

the mechanical difference by trial and

error and we can have different

these triangles

and on this triangle you you can kind of

say like

it will be like uh

a hardness

like maybe it's a soft on it

and

that soft thing is shorter to offset for

the slower hit

lucas solved it

which means that we can move it from the

known unknowns

into known already and we're getting

there next the sign

uh i'm the one who pressed marblegate

let's have some water and let's enjoy

everyone ascending a fantastic level of

i said to hannes before the stream

the audience who are here now it's like

really the hardcore

interested people we don't receive a

single bad suggestion like every

suggestion has been interesting so far

which is kind of crazy the level of

brilliance in this community is insane

you're terrific everyone who's tuning in

here and as i said earlier a lot of new

folks

are joining the chat today and that's

really fun to see you here so don't

forget subscribe awesome like this video

it helps us

be more visible

hannes

sir 3k has a subscribe upgrade and i

just love it

absolutely love it

marblegate

uh dexter

so this when you open this

uh more than one marble will fall down

and be loaded but the pacman gate which

is

a little bit what you have designed here

is actually in the an interesting

solution again i also been talking over

email with my favorite swedish artist

john cardell about this

um

who is an amazing mechanical instrument

builder so you're on to something but

this very version would

um

you have only drawn one marble on the

top but i think when you open this gate

you will have four marbles loading at

the same time

i am like me

no bad suggestions hold my teeth

dual channel clock escapement gate two

dropper wheels on the same escapement

okay i've seen this uh several times

actually or two times now from enoch

daniels

the reason we have only eight marbles is

that uh zero figured out that that

leaves the marble dropping to be the

most secure because of the angular

rotation

uh on this wheel every marble would just

rotate a little bit to be dropped

and as the signs on our wall here says

what would rousseau do so we should not

um mess with perfection so

enoch thank you but

rousseau have made it otherwise

bebo champ mark robert

uh rober

just did a video about an automatic

piano i saw it actually that does a

beautiful breakdown of the function of a

piano hammer i think it would be worth

watching that part it starts at

timestamp 142. mark robert's videos are

and

amazingly well made i i saw the video

actually

and i also thought that that video was a

great uh demonstration of how boring it

is with solenoids

so i mean the piano was super impressive

but just putting solenoids

it's just a one-trick pony i feel and

and you get bored of it very fast but it

was beautiful beautiful beautiful

um and very quick

two gates dropping on the same key to

avoid doubling keys you don't drop in

the center anyways always open gate one

first falls lower than gate two ball two

cannot catch up and collide with ball

one um

and mad props for your

your photo editing software here yeah

it's is it paint

paint or early photoshop i don't know

it's beautiful it's beautiful

from in dooney this is basically exactly

what we're what we're going to do so

um

we we are going to do that um inverted

belt drive for marble gate from timing

wheel

inverted belt drive for market from

timing wheel

by jared so i think this is an extra

part

um

we do

yeah i i think it's it just adds too

many new parts

by kevin anand

in marvel game redesign not being played

not not needed

when used

in the bridge is halfway to prevent any

furthermore fall then when a knot of the

programming wheel it pushes the bridge

into place

so this looks like

this is very much what we had

on the first gate on the machine oh can

can i read the text

when not used the bridge is halfway to

prevent and

no it pushes turn bridge in place this

lets mar fall and then when it's not

when when the note is finished or not

needed it moves back to the halfway

point yeah it's it looks like the

the gates that i had on the martian x

it's actually the gates that are on this

image if we go to if we go to uh my

uh cat

um

these are actually the gates and as you

can see gates not reliable

so

the clock escapement gate or the pacman

gate are superior in in in almost every

sense i think

marble get placement idea

could it be possible to mount marblegate

below the arc of the vibraphone marbles

no need for a giant drum if you do not

need to have one

um

yeah perhaps

it's a lot of

if we make the machine very high this is

possible

and i just think that this is an uh

to put them on the side of each other so

we don't have this problem at all

it just seems to me just to be like

ah

do you see what i mean oh yes yes please

can we get to that zone

everything

convoluted on top of each other is

causing us so much headache

um the havoc machine

if you rotate oh we saw this one before

um this one um we checked before

love it

drop caught my fabric funnel vibraphone

backup drop caught by fabric funnel this

is basically exactly

how i've been imagining

and i think this is going to be so ugly

except if we make it circular then it

would look like a beautiful ballerina

a skirt almost

or like an upside down mushroom

so this

is um

how an idea should be presented like i

wish i could sketch this clearly this

just tells exactly this is a brilliant

idea

if we would want to do

this turns around everything that i

thought of i had

all the time turned around it's a great

idea

if we want to make the convoluted thing

where's the resonator pipes though

so that's the thing like here it looks

great

but what's missing the resonators are

missing

and they would

make just everything impossible

so

um good idea but i don't think it's it's

working now this is a viable one so this

one

i saw this one behind the stream and i

don't know if this is

low-key

the

the worst like what is it called

control right

it's rolling

this is the best trolling yeah

and a little little teasing of what

we're trying to do here but i love it

100

so marvel's going inside submarine

string is released causing the submarine

to flow to the top marbles are released

at the top tank is filled with water

string pulls submarine down

yeah i know i know i know i know that

midi keyboard is better the case for

constant drop height but it was fun

though the case for constant drop height

well let me just fix it so it looks even

better

there we go

brilliant

oh we didn't give credit on the last

image um there's sadly no chris yeah

paul pingas paul fingers popping us

the case for constant drop height by

rare earth um

so these these are some mathematics to

prove

that if we don't have constant drop

height oh and if we make modules what

can we have

constant drop height

so i think someone has done a lot of

thinking here so let me drink some water

and actually really go through this and

try to understand

because these graphs uh these

formulas what is it called

it's fun that the cartoons of us are

smart hey the smart people are back we

know what it's called it was the

cartoons who didn't know what this is

called it's called equations okay yeah

and i just want to once again hear

with all the talk about the

piano hammer

kevin mullart i concur with beboot champ

not the solenoids the design of the

piano hammer as an inspiration for a

drumstick seems like a good idea

and then

other people in chat is also like plus

plus one on this side like check out

how the piano hammer works

yeah the piano hammer has a very cool

reset function um so i've been repairing

piano hammers

on my own pianos but

i haven't thought about it for a long

time so definitely a good idea so thanks

for pointing me to this

to it um

here we go

the case for constant drop height

drum rotation is constant at each tempo

pins have a linear velocity relationship

between when pins trigger is linear with

distance

and then some um some

egyptian hieroglyphs down there which i

don't read

we can call like a hieroglyph expert

perhaps i've seen them in these tomb

documentaries

marble starts at rest acceleration from

force of gravity is constant

time between marble release and hit has

exponential relationship with distance

i'm gonna try to wrap my head around

this

gravity g 9.8 meter per second squared

drop distance by d drop hit velocity

this is so cool because i think this is

actually like because

my intuition i made the constant drop

item on the war machine x because i knew

rare earth is the goat son of astronaut

oh is that true is that

is rare earth like a

a youtube channel or something

please chat because i kind of recognized

the rare earth

maybe you can find it out sir 3k

chat will will tell me

um

because i did recognize the name

um

can we go back to our cartoons oh there

was not knowing in

no nothing behind there conclusions if

instruments are at different height

between dropper and impact the distance

between pins must be adjusted but you

already know that adjusted pins will

only have perfect timing at one tempo

because the pins are set for a linear

displacement to just an exponential time

and drop distance relation

if every drop is the same height then it

doesn't matter how much time the marble

spans in the air it is better for timing

to adjust the dropper heights small

adjustments to get a constant drop

distance rather than moving the

registrator like you currently plan love

this um

this lesson

and i feel i shouldn't have skipped so

much math in in school

i'm i want to stay a little bit of this

because i think this is very important

we should definitely go to the design

requirement documents

um to to talk about this

um

rare earth rare earth is a great channel

but no math involved yeah i kind of

can can you pull the channel up on us

because i think i've seen something

um so that's let's see rare earth

comments also no i'm not that had filled

rare earth but i'm still cool

okay oh rare earth you're here

so fun that you're here thank you so

much for for your wonderful lesson

and you're wonderful like it was like a

mathematical proof so this is where

where this gets super super fun it's

almost like a mathematical proof on why

a design requirement should be in the

design requirement document so

i'm going to

just

improvise here impromptu

marble

marble

drop height um

and registrator

timing

proved

we have to rewrite this by rare earth

um

similar

same

drop height

is

it's

best for

timing blah blah blah i

never mind my bad language right now

um

so elia g the easiest solution is

clearly to adjust gravity depending on

each song's tempo

i would like to add like

drop time

so for example if we introduce a little

curve

to delay the drop time

and if that curve is constant so

if we drop one marble from high

unobstructed we drop one marble from low

with a little curve and make sure that

that curve adds a delay so they always

have the same time so i would say

actually that drop time

is drop time is the important

part

equals the time

it takes for a marble

to fall

from release

to hit

so

um

for the machine

to play tight

in different

tempos drop time

must be constant

so

the design requirements

be this marble drop time must be

constant

um

and and this this will be another

reason for the modular design

um

because

i did do it on the machine x because

everything is right next so to the to

the second point of rare earth

um

can we go back a little quicker we can

um that it's better to uh

adjust the tempo

in the marble

drop height

is interesting smaller just wants to get

a constant drop distance

so

this is kind of my my um

my small improvement on your thesis here

rare earth

is that it it's actually the drop time

that that we that is the thing

um

so but maybe you took for granted what

i've said that i would have everything

in free file and then it then drop

distance and drop time is the same thing

and i was thinking about skipping

height control this time around

because i wanted to make

i i just want that was a super annoying

part of marmot in x

but now you makes me make me think and

if we go back to the design requirement

um

re because i still think that we

definitely

registrators

must be adjustable

um

because what i realized um

and you need something to equalize the

timing for the drum machine yes from mr

gone snider like a

timing clutch

so

on the margin x when i switched four

centimeters in drop height i didn't see

a difference in logic pro on this on the

recording it was like

it's

it was so little time difference so i

could almost not record the difference

so

maybe in the best of worlds we have both

adjustable registrators and adjustable

drop height

and in all honest in all honesty i never

got really to trying different tempos

so

before in my mind i said i'm gonna skip

the design requirement to have the drop

height adjustable because it's annoying

but after i'm seeing your papers i think

i'm going to put in registrators must be

adjustable

drop height

must

be

adjustable

or

or drop time

um

are you trying to wake me up no i don't

want to say that we got a little nice

supporter from i sack so thank you very

much fantastic beautiful human being and

thanks

thanks for this thesis let's go back

i've barely belated the point enough

already i can have a second one here

yes

this was wonderful rare earth thank you

here we go single axle with cam lobes

that are 180 degrees offset would allow

you to simply rotate it 180 to engage

one side to the other

uh

can you remove us

there's nothing team

team camshaft

yeah so so um

simply rotate it 180 yeah so i think

this

this is a question of taste in how much

um

how much travel we want of the boating

cable it might be that we need want as

much as possible

to better hit the perfect peak because

it's about the resolution because if we

only have like 10 degrees maybe it's

super hard for me to hit with the lever

as a fine adjustment maybe it's easier

if we rotate exactly 180 degrees

and maybe we can also make the camshaft

so if we do 170 it's still correct if we

do 100

290 is still okay

so redund um resiliency in the angle so

it's not so sensitive and still make it

work

um i think it's a good idea

uh next design a b programs and muting

pink axle inside holes green one

so this controlling a b channels and

muting would be done by two levers

rotating the pink and green axles at the

side of the machine

this is the pipe and pipe solutions

and with six or seven individual

instrument groups things are starting to

get too complicated but thank you alien

i alienator

muting and track changing registrators

are always engaged

only the connection to the gate is cut

off

this mechanism was in the other old

machine each track has two registrators

for changing the music inner joshua

gretzky of engineer skating where the

puck is going this is exactly uh the

solution that we have came come out with

and you reach there independently i'm

super impressed this is the solution

that works well done

there's more from

inuyasha while unmuting the gate

connection comes down but does not

transfer movement yeah this is the same

solution yeah i'm super impressed that

one more you got it

muting and track choosing it's the same

and here we have more camshaft things

with the a b state that we have now

excluded but thanks for the skate sketch

and here we have a bowden cable lever i

think by overdubbed this is how the

cable goes back and forth

um

square bar with identical cam profile

stacked and rotated depending on what

channel it corresponds to

love it easy to manufacture

um

and it's from a swedish person i think

because you can see on the box there's

some swedish there so

thanks from a fellow swede

um

and a fourth shaft that will allow

you to quickly move from green to both

and red to both so the both state

has been cancelled we don't need the the

green parts here in the picture but good

good idea if we need the state

oh it's a video i think okay let's see

the video

i love when people are using lego

what

beautiful

also this is the train

thing

wow

cool it's the master lever

thing i love the the

the

the straightforward examples thank you

you have an image immediately after

thanks so much for that yeah master

level levers beautiful demo thank you so

much whoever it was from

uh channel one playing both channels

muted

channel two playing how is this

uh

channel one playing

oh they cross each other that needs two

pivots more complicated i think

um

did we see this before no

use detent to give feedback on the

rotation yes that's the ball

um that's to make the lever stay in the

correct position to determine the muting

state of what it's playing use a machine

rod that is shaped such that its

rotation determines whether b is muted

yes

so i think this is spot on this is what

we're going to do

out there

[Music]

nice timing there of the sound you saw

it in the next slide i did it i cheated

go back one beautiful look at this

yes this is brilliant this is a template

that alfonso samano made so

if you suggest

you can take a screenshot of this

and just use this

because of course we are obscuring this

area yeah these annoying people are like

always obscuring in there

so alfonso samano great idea in the

speaking of great ideas in the spirit of

no bad ideas mm3 junior um detachable

row of mm3 junior registrators bowling

cables to

another but this is the module id

actually so alfonso

i'm actually contemplating using this

very idea so absolutely no bad ideas

i think what alfonso is meaning here is

that you can read the programming wheel

at many times at many points and send

the information through bowden cable to

whatever you want to control

oh

uh hi martin get one of these for

controlling your viewing cad spend 20

minutes to get used to it and you'll

never go back to using your mouse to pan

around ever again best tool for cad ever

suggestion from dk i have the one on the

um on the right the space mouse compact

so my question and i tried to get used

to it and i couldn't i can't get you to

use a magic mouse so how is this gonna

work

but i do have problem with tendonitis in

my right elbow me and matthias bundle

have that in common

and the only thing working is actually

it's actually lifting weights

and

so i'm thinking maybe this could help me

but my question for to you yalta is

are the more fancy models better

is it because i bought the cheapest

simplest one that i didn't see the the

reason

do i need to go for the starship space

mouse enterprise

[Laughter]

on the left thank you for a great great

great suggestion program installer from

iphone so i think we saw this

rollover drum this is a little bit too

complicated alpha so i think the the the

wheels are better

this one we saw as well um in another

stream in another stream it's a

brilliant idea for tuning resonators at

the moment we're not tuning resonators

but for example if we want to make the

11 note module

and we don't want one resonator per note

this would be the solution love this

idea by

amr alpha and skill stalker who made the

cad

gussets

so

don't waste gusset here already stiff

because of triangle

oh this is a good this is a good um

point put gussets where they're needed

basically that's that's a really good

point dear martin team

i'm glad that you're now using some

validated tools for decision making and

analysis another great resource similar

to the one you linked in this week's

summary vid is

and then a link

it's a handbook from an organization

similar to the asq that lists easy to

use tools for different times during a

process improvement journey the photo

below is from my own pocket-sized

version

and shows how the tools broken down by

topic or possible use you can order a

large size too i've used these tools in

the past to train process improvement

teams wow this is so so gnarly to train

process improvement teams

in a large engineering company with

great success oh

i pressed something you really pressed

something

let me help you sorry everyone

yes thank you

um

we also sent our teams to a global

competition for such teams and my teams

who used these tools and handbook were

judged best in the world

not once but twice

not bragging trying to encourage you

your continued use of the tools smiley

face cheers and best wishes from me here

in australia dallas

um

former

youtube member thank you so much this is

so this is so interesting like i love to

learn new stuff and

my

my challenge in this project

is to just use the tools enough but not

making them separate rabbit holes

so to just inform myself on like

how to avoid the worst practices

but definitely going to

um

can you maybe pull that link up

goal

qpc.com

not at the moment no exactly not when

we're running this okay slideshow okay

so thank you dallas so much and we'll

definitely look look more into it

uh fishtail is suggesting

a testing ideas folder to the dropbox

here we can add ideas for

at the point you decide that the cad

file does represent a viable machine

that you want to build you should add a

testing ideas folder to the dropbox here

we can add ideas for what to test the

whole community might be able to come up

with tests to uncover unforeseen issues

some of us are really skilled at finding

failure conditions

in this case

so

fishtail took a picture from my

explanation why the martian x didn't

work

in this case we might have suggested

what happens when the tube fills up and

cannot accept more marbles by fishtail

this is

gretsky skating where the puck is going

i think

i have different chapters of this

project

and right now we're in the

thinking about if we should do the

project or not and i'm going to try to

make a cad file to make this decision if

if i should build a machine 3 or if i

should actually if it's not worth

pursuing at all

so

once we are once we have a cad file with

everyone

can know i would love to

do this kind of thing

because i think

this is going to be so cool to put it

out to all of you who can see the issues

in the cab that i don't see

it's what makes me think that we can

make a cad design that will be

manufactured and work

first try

so i love this suggestion by fishtail

it's going to happen if we are deciding

to to make the machine

modular mm3

by mr burns vibe drum franken mm3 love

it this is very very practical this is

basically i think the best solution

right now

a lot of programming drums will be

needed though you don't need a lower

drum on the vibrophone

and you only need one and maybe only one

on the drums so

maybe you can remove two of these drums

and control the drums from the left top

drum

it's actually an idea to this is

actually a sketch to remember

this is kind of form from function i

think anus yeah

to make marbles more visible use

fluorescent paint um

kind of cool idea

i

yeah maybe maybe it would work maybe

maybe the tolerances won't be so

uh

problem and if we use these wooden

marbles

they would take the paint really well as

well

machine touring version designed to be

played with the band the machine plays a

midi vibraphone drums and bass can be

played by the other band members

so kirsten tart has really gone the what

if we made this simple

um

me the vibraphone though

um

[Music]

so in a way carson tart is

kirsten tart is

into the modular thinking

so what's interesting with the comment

we had before that if we make it modular

we can mix and match kind of instead of

the all-in-one

um

and this is kind of you have a

vibraphone module

although the midi vibrophone it's like

oh it doesn't feel right for me it feels

like done

we can use a midi keyboard with a

vibraphone sound

but i love the modular thinking here wow

how this how did this slide managed to

get on air i don't know

everyone knows that the best way is to

have sir 3k spitting out the marbles at

the correct place

and it also says school on the front

wow

marble pass as previously

uh let's see this is a beautiful sketch

can we remove there we can

splitters and mergers caused issues and

added complexity

lift limit nodes count marbles hard to

catch

one lift per gate

no splitting merging reduce the height

to the minimum minimum to play the note

pros increased reliability high marble

throughput compactness

so

my take on streamlining designer

removing parts boone is cool points for

you if you can make a one plate gate and

lift assembly

one plate gate and lift assembly

hmm so

the idea is is to have isolated loops

which means that the base notes

only go into the base marble lift and

the base

marble gate

so you have isolated echoes

echo systems

um snare marbles goes to the snare

only problem with this is that you have

to catch them accurately if i play this

note

it cannot be catched by this funnel

which it's next to it

so

my idea for the marmot machine 3 is to

only have one large funnel

and then we need the marble gates but on

the project that we've been working on

during the break the machine maker kit

we

we tried to have isolated loops and it

worked really good

so it's a good idea but it takes

the lifting system will be much larger

and the capturing system needs to be

completely exact

we have to catch each marble into its

specified marble tunnel that's difficult

i just want to say here doro doing the

lord's work here

when people understandably

questions why the mmx was uh not pursued

anymore

doral

pointed

that those people to this link please

have a look at vintage.net

pages and mmx there you find the

explanation why the mmx was not ready

for performance great job doro thank you

so much doro and at queen we really

understand that people are wondering so

i made a picture exactly for you

and um so go there and you'll and you'll

see the explanation yeah some of all the

problems that's not all not those who

fit in one picture

so here's a suggestion for a mini camera

for video and here is a suggestion to

use a space relativity space to make a

um

organically created it's from magnus

science and again who had another

suggestion earlier i think

so these are space grade metal 3d

printer probably super cool but very

very custom and a little bit um

nervous about um probably really cheap

as well repairability and maybe a little

bit

um

maybe a little bit expensive but metal

3d printing is is the future

guaranteed

maybe a bit too ambitious but maybe a

solution to avoid marble collision so

the same idea as a lot of people have

and matt m credit for like showing all

the marble lanes and stuff like that

um

so i just don't like this i don't like

to have this

it feels like people with um

with masks on during corona it feels

just like it feels like we're just

muffling the whole instrument with these

walls

and i rather play a mini midi keyboard

what if it was see-through plexiglas

yeah it's plexiglass

so it's a great idea but i just feel

like let's just

it's again this whole con convoluted

everything is on top of everything and

we can't be free

making the marble gates for this will be

super difficult

um

i love this suggestion but it reminds me

of why this is so tricky the the

all-in-one machine idea

same suggestion

bloghost it might not have functioned as

expected but martin definitely made a

piece of art with mmx thank you for that

uh nice comments used to forget that

sometimes yeah yeah it's i don't yeah

you were in the deep with that machine

you didn't see it from the outside as

some of us did okay

yeah

i've seen people react to it when they

come into the room they are like silent

for five minutes so it has a it has a

big impact

um

this is cool drive train under the floor

this is a real steampunk old factory

kind of solution

under platform marble collection area 90

degree power transfer case

um

oh yeah that's how it can be done foot

pump control levers

foot pump drum zone

bass controls xylophone

so mike rathbone

hi guys sorry for the crude artwork your

artwork is beautiful i have one big

criticism though

xylophone we're not playing inside of

when we're playing vibraphone

what was the name again i missed it

because we're over it now

mike wrath

love this sketch mic so thanks so much

for sending it

and

i mean

talk about

visionary thinking

and so the shaft that connects all the

machines you could actually have it

above in the air as well

um

super super cool

and ralph is here yet again with this

wonderful modular thing

okay everyone we are going to a smaller

problem

but one of the most inflammatory

the flame and the fire that have been

thrown at each other in this discussion

and we start with something inflammatory

right away so damien villa has made a

beautiful presentation of this um

totally overkill programming pin instead

of removable pins use integrated pins

with lashing latching mechanisms like a

retractable pen

and

the reason this doesn't work

is that we need 50 000 instances on the

programming wheel

um

so

um

the concept is brilliant but it will be

way too hard right yeah there's just too

many

they can't fit physically on the machine

and 50 000 of them

etc etc there's a video

so this video is when we had to switch

the programming pins over

and i'm gonna shout out where the half

hits would have occurred

um

because right now it was changing

you can't change whenever you want to

with this design

so our new design is uh more um

resilient

and

programming wheel ideas

um so this is the slot in idea this is

we're not going for this anymore because

we are having it removable

and paper roll we're not going to use

which will sketch though

machine media interfaces from michael

with programming wheel requiring cutting

to program it

it is harder to experiment

oh no that's not true so when when we do

cutting we can put a pin anywhere so the

cutting is just a

template as a white sheet so you can

make any kind of any kind of music and

so there will be

so here's also suggesting solenoids and

i want to do the world's

best sounding best playing

mechanical instrument that has ever been

created um

and easy enough here we go mechanical

means no electronics so so that that

goes away

um thank you for for the mutual sketch

and this is beautiful

um

so this is still the removable

programming wheel

or is it moving sideways programming

wheel can put on a shaft from one side

without getting the belt

same can be done for the drum wheel yes

so this is the old we've moved forward

from this we're actually removing the

gear with the with the programming wheel

and here's a cool

kind of thing a programming sheet

um so we're not doing

oh well this is great so this is a

template made from a durable material

like tyvek and printable on a large

format printer to aid in programming

songs the sheet is relatively

inexpensive and you can have multiple

copies in case one is damaged lost or

given as a souvenir

sheet registration feature on drum

so this is from robert thompson fort

collins colorado

um

there's going to be a south park concert

in colorado sir 3k just informed me with

the band playing the south park theme

song

so if you're in colorado maybe check

that out i think it was in colorado it

should be

um

this is exactly how i'm thinking that we

should use so this is just for the

programmers to know where to put a pin

in

[Music]

the sheet can be automatically generated

with software from a midi stream

manufacturing requires cutting each hole

so what i think is that you can actually

make this on the cnc machine with the

rotary feeder

we saw this

before

stephen clark from switzerland

programmable elements so these are the

dragon slayer plates i don't want to do

them again programmable elements so not

the entire thing right

yes these are the four seconds yeah

these are the four sections um

maybe

maybe

with the rotary cnc machine

maybe i shouldn't be too quick to

judge this idea away because of course

it would be

it would it would mean

let me go and

open

open this

hello

here we go

there we go so

with something like this i think these

sections that you're suggesting can be

made much more accurate than the

sessions i was struggling with

so

and then they could also be made for the

loop wheel so

if we're just thinking so we're we're

down to trade-offs again so if we're

just thinking about um

about

touring

with

four of these

with full structures

and gears and everything

and they are huge

or

we have the templates we have the

skeletons on the machine

and we're just touring

with a whole stack of half moons like

this

it is of course

very efficient

but i am

your check v2 main no i recognize your

name from one of the suggestions yoshiki

cool no don't reintroduce the dragon

i feel

that's how i feel spontaneously

um

i

[Music]

the precision i want of this wheel

which

we have to be able to snap these on and

off

and we can't have holes in the edges

between them

i agree we're gonna have big trucks

enough ramstein takes fire flames that

are like 30 meter high to their concert

and i'm planning to

play at least 100th of the size of their

arenas

flexible room removable programming

plate

the flexo printing

uses such a system perhaps it is

possible to create a flexible

programming plate that attaches to the

rotating tube so it would be possible to

create several songs on different boards

and only change them as needed would

save a lot of space and speed up the

change process all the best from a

brazilian tea lycra or licre

maybe that kind of clamp could hold the

flexible this is spot on um this is

exactly what i want to do

and if there is a process where you can

also make easily make holes in

this flexible sheet

um that would be awesome

um

beautiful

project management nothing there so

moving on from that section and the

audience is like

we don't need anything from project

management in on this channel

idea for how the registrators move to

switch paths okay we do not move the

registrators anymore but thank you so

much for the suggestions from jacob from

jacob

um by jayden t um

black and white registrators are free to

slide

brings the receiver to

buy cycle cable

backup registrators are heavier

not immediately understanding it from

jaden t australia

registrator

i'm not getting it immediately and i

don't see if it's simpler than what we

have

no half hits so this pivot thing we

looked at before we're not going to do

that

cylindrical registrator internal acme

thread external acme thread on lower arm

lasse so this is a way to adjust the

timing without having the extra screw

it's kind of interesting

um

[Music]

what is an acme thread actually

is it a bigger thread can can we google

that i can google this a little quick

you can google it my i'm

locked in here

you have my keyboard as well yeah i do i

do

across red

um

[Music]

oh yeah it's a bigger thread

what does aqua thread stands for

american screw thread oh there we go

no no no america

between

it's another kind of threading okay yeah

i think it means that it's

um

it's more like a machinist thread i

think

oh wait here

[Music]

overdubbed uh rotating the assembly oh

i am like me uh gotta go but i think you

should tame the dragon and use his

psychic abilities to help guide the

marvels to the right notes no bad ideas

hold my teeth thank you so much for the

support i am like me and the the

wonderful the comment keeping us

light-hearted in in this process love it

like the fun we're having together like

it's it sounds stupid but it's so

helpful it has boosted

this project like 200 percent yes we're

actually having a lot of fun yes

yes although i'm

currently scared for for the modular i'm

here to hold your hand it's gonna be

okay

i'm daunted by this machine we will

wrestle it down to the ground together

you can wrestle while i'll watch yeah

drink your coffee i'll wrestle here we

go

over dowd is sending in rotating the

assembly with an offset head could solve

your problem with half hits

so this has been solved probably super

smart solution but i want to use the one

we have

um mechanical paper interface

um

wow what a sketch though beautiful

sketch

oh yeah so the support will

be what spring

do we have a credit on this one

oh i can't see

no small size long programming is mute

interaction

so so this is a cool idea that i haven't

okay so yeah it's worth just to

explaining for the viewers

when the paper

is not

strong enough

this is something that i also think has

never been done

um

in the history of mechanical music so

the paper is weak

but to help the paper we have matching

holes rotating underneath so the little

lever falls down through a hole in the

paper but it's carried forward

by the

teeth in the programming wheel beneath

and it's this beautiful solution i've

seen it before

i think what would happen though is that

all the registrators would slide on

the paper so it would make a big

sound

at all times

because they had to have some

pressure down on the paper

to fall down into the halls

but it's a super cool solution we're not

going to use paper but if we are

something like this could could save us

and cypunk215

teaches us akhma literally means the

highest it's a common name for various

businesses in america it is also where

the coyote buys his devices to kill the

road runner

and also their acme threads are strong

to change rotary forces to linear force

as seen in a vice

from mr b fox 1775

and

we have a new chapter timing belts maybe

you should read out the chapter names

sir 3k

timing

belts

on but you have to read them with the

the sound then it's give me one more

chance then

timing belts

in the section of timing but this works

this works this this is going to be

great hang on here

the mohan of engineer galore

gretzky hall of famer who have come up

with so many beautiful suggestions for

the machine x thanks for not giving up

on us demo and you're always bringing

the goodies simplicity with gears

option one

if the programming drums go opposite of

each other it could be like in the image

with two gears from the one to the other

option two if the programming grounds go

the same way one gear in between would

fix that for both the gears can be

bigger smaller than the drums can still

use herringbone gears yes gear ratio can

still be one to two

preset timing can still be

adjusted with the dividing head design

no belt on timing critical equipment

demo and i have to ask you if you ever

hear this

do you think

that belt

has less accurate timing than gears

because

i thought that this was impossible

because i wanted the

loop wheel below

to have a one to eight gear ratio from

the crack now i actually want to have it

to have a 1 to 16 which means that we

only need a

one to four gear ratio between these two

drums which actually could potentially

work

so your solution

might be

viable is what i'm saying and i am

i have been thinking about maybe taking

back the herringbone plywood gears so

i'm curious why you prefer them over um

timing belt

timing indexing for timing indexing we

are seeing a solution from john lee

um let's see here this is a beautiful

sketch we have to click ourselves away

um

what is this

um

timing of the machine can be controlled

through a series of hypermodal

angulative

mattresses

and any luck ambulatory feedback is

rerouted through the primary polycyclic

and cafetolab biography shaft

effectively eliminating nearly all

perceived relative face eddies this can

be achieved by using an encapsulator

device which uses six hydrocopic

marshall veins and an ambi efficient

lunar wane shaft to prevent unwanted

side fumbling john lee inventor and ceo

of over 30 companies

john you have to translate this to

english for me

so um

super cool um john to see that you are

um

uh let's see there's one of two

oh yeah maybe we can come back here into

into frame

um

lunar rainshaft

prevents unwanted sign

wayne shaft and moon gears goes in here

connected to program with

earth gear

so there is rocket science here

so um

wait

so john

ceo of over 30 companies i'm only ceo

over one company and i guess i have to

learn some new words too

this was impressive and the sketch is a

total beaut right yeah that's super cool

to have you here john

i'm

it's way over my head your suggestion i

don't there's too many words that i have

to learn

so

is it possible to dumb it down

um

and idea to be perfected

and i'm also curious like where all the

way original machine

so what i feel with this suggestion is

there might be some genealogy hidden in

here that i'm not grasping at the moment

mm3 timing solution

level of development

and you get so much into the sketch so

i'm i

okay let's see if i can understand this

when shaft and move

connected to program entire assembly

goes on programming wheel

is it kind of a gearbox

marcel veins

there's so many words i never heard

[Laughter]

it's super fun to get your suggestion

and and

wish you good luck with your 30

companies although i don't think you

need it it sounds like it's going

everything that was pretty hard to

understand but something that's easy to

understand is that we have the best

community in the world and this is from

miguel antilla martin the mmx might not

work but the journey was such an

inspiration and gave me so many tools

for dealing with creative projects

loving the new format and new journey

always inspiring and a heart emoji and a

heart emoji right back at you thank you

so much for your support that's

wonderful

thank you so much mikkel it's it's it's

it's really nice to hear that that

me trying to do something even though

i'm failing

it's i have given some value to others

that means everything so

thank you for that we have an

explanation of the sync solution

because i asked for it so the inside

thing adjust the tension

and the outside thing adjust the sink so

thanks for explaining pedro now i

understand this sketch

people are saying that it was absolutely

trolling that last one

trolling here

no it's a 100 a troll boss this is an

ancient engineering joke

yeah so i think we have two trolling

jokes today then

[Music]

which is

we both have the the

submarine solution and we have this

um

turbo engine later is a joke look it up

it's hilarious

[Music]

i just want to say from fan here hannes

you're the ultimate hype man yeah thank

you so so much that means the world to

me

that's true that's true okay so

i

i'm

our wush on the engineering joke over me

i thought someone uh made it okay wheels

for the machine yes we're gonna have

wheels this is cool though wintergatan

proposed the mark machine three frame as

a hand track

and these uh roto caster wheels provide

movement in any direction this is a

pretty cool submission they look so

badass they look badass so thanks to

whoever sent this in

we have from isaac

one unnecessary tall two not a strong

but could use dummy axle three stronger

of all three but not too tall could be

in front or slightly up and used so it's

the back brace there it's a good

suggestion here from isaac

and we have more casters people love the

casters thanks to cason mc for sending

these beautiful casters and here's some

lift of some sort wow

that needs to be incorporated

this is um

oh this is actually very relevant

this is that

the fact that they're tilting this to

get this inside doors

[Music]

look at that little hydraulic thing

this is actually maybe super super

relevant to have the machine just tilt

the ball

and then the height does not matter

anymore oh ba-boom

then it's kind of baboom so if we want

to have the all in

one solution this would be very very

helpful

more casters

uh and then we have the

vibraphone vibraphone okay let's go to

the viral phone

so these angled plates

are problematic because of the rotating

shaft underneath

um i don't think we can do these angled

plates because the vibrator shaft they

have to be on one plane

um but thanks for the idea from

anonymous

vibraphone hammer jammer from alfonso

who sends in a lot of suggestions thank

you alfonso

and i'd rather play the vibraphones with

the marbles direct it feels too

convoluted to have the hammers i am

thinking maybe making a machine with no

marbles at all and

i'm only using mallets and sir 3k has

baptized that machine to the mallet

machine yeah yeah what a letdown

everyone

we'll we'll see

digger mia

with the beauty leaving them hanging

with that yeah

mallet machine the mallet machine so

show me chad how many are team

can we make a poll marble machine

machine no no melody machine

i'm not doing that poll not even a poll

no just for fun

just two options

what should we make marble machine or

mallet machine

is well i'm just curious to see

two-sided fabric cloth

big part

oh yeah this is pretty cool but again

it's like the mouth protection

i i was using mouth production all the

time i'm not against that

um

youtube don't cancel my channel

um

but this feels just like we're covering

it up too much

here's the same ideas that someone else

have dropped from behind

it's still this convoluted feeling it's

a beautiful sketch though

this is cool this is the circular idea

and i have to sketch how big this circle

would be this is the attention-grabbing

design

so

if we want to go viral again like last

time this is what we're building

but is it form from function

is the is the question

so here moving things to the side

from danny way

same ideas others have

convoluted but would work but hard to

build hard to build

vibraphone marble collector oh it's a

hammer jammer idea for the vibraphone

same as alfonso had

and here will speed up the the

registrator but this idea doesn't speed

up the marble release which it's our

limiting factor so it won't make us um

play faster but it's a beautiful idea by

ls

and here gunsonator's vibraphone spiral

thing of true beauty think of true

beauty only how do we put the marble

gates for this

i think this would be

very difficult to to feed with marbles

and this is one of our favorite sketches

of all time

the wide mm3 by crafted by aura have all

the instruments laid out as columns so

no overlapping instruments that's what i

mean with the convolution

and you have the marble

lift in the middle there and i can play

the vibraphone manually and you can have

the snare drum on the very far away

right so away from the vibrophone

this is probably the most practical

thing we can build um

well look at this proudly supporting the

mm3 project with useful design ideas

since 2022 the oregon guy maybe this was

people yeah yeah yeah

barrel has 44 tracks for the vibraphone

22 each for track a and b from the

registrator exit only 22 about in cables

to the vibraphone the vibraphone has

the gates are orientated in a v

formation to allow playing black black

and white keys

without cutting the ots microphone in

half the 22 bowden cables get attached

to marble gaze as required per barrel

what

smaller barrel that's not chromatic

all gates remain untouched between

barrels manual playing on margaret's

room impossible for

small amount of making changes

hmm

this is super interesting but i don't

understand it so

2 x 37 marble gates the gates are

oriented in a v formation

to low playing

black

the

ots

over the shelf vibraphone in half

but how

22 each for track a and track b

i don't understand how

22 bowdoin cables

can play

two

can play 37 marble gates

can play

two times 37 marble gates

how do you transfer

so my question to you um the organ guy

is how do you

how do you control um two times 37 gates

with only 22 cables

that's what i don't understand but i

would love to i would love to know if

it's possible it's awesome

angle the marbles onto the black and

white keys in opposite direction with

the vibraphone sitting level this is

probably the v

v idea

you still have the mid air collision on

the way down here but that means that

you just can't play at the same time

which you should probably yeah you want

that when you play a chord

so in this solution you wouldn't be able

to play

a chord like the x-files at the same

time

[Music]

there we have organ guy attached as

needed per barrel

um

[Music]

i still don't understand how do you

how do you get 22 nice to see you here

the organ guys thank you for your

suggestion

how do you um

[Music]

are 22 active channels you couple them

as needed ah

so you move the connectors for each song

ah i'm getting what

now i'm getting the idea however

if we if we have gone through the hard

work of

actually making 32 x 37 marble gates i

want to be able to play them all in one

song

um

so we're leaving too much um potential

unused and by the way organ guy thanks

for using the

um upload template

brilliant brilliant

um

i'm gonna end this poll now

327 votes

81 for a marble machine okay

i still have 19 with me on they're just

trolls team

i'm ending this now

you're ending this suffering i'm ending

this okay so paul has ended

milo's machine is not popular

37 key modified keyboard to play marble

machine manually first set of bowling

cables go to the barrel

um here's a v formation secondary set to

a 37 voting cables

known issue no fast double notes as only

one gate

yes i was aware that you were planning

on doing the manual solos with actual

mallets on the very phone but then you

might as well play on another vibraphone

not to one from one machine with my

suggestions you're at least not reaching

inside the mechanics yet still play

marvel's so

several suggestions are pointing at

should the vibraphone be manual manually

played or not so let's go to the design

requirement document just what the organ

guy just filled in there also

the idea is you do not need all notes in

each paragraph yeah

i i see um that's it's a good point if

we need to make the barrel smaller

um

definitely um

but i think

if you only have 22 tracks

on the barrel then i prefer the mandrake

module with only 22 knots that's

then we don't have to reconnect the

bounding cables we just plug in the new

nodes and we plug them straight out for

the next song

um

and maybe we end up having to do

something like that um

vibraphone requirements

um

so

the big question is

the vibrophone

must be manually playable

with

mallets

and marbles

and this is the question mark

um

so in my mind

just because i did it in the first video

i haven't thought so much about this

i think

what do you thinks are 3k marbles

no no no this is a

[Laughter]

i see mallets there okay yeah so the

question is in the original music video

i dropped marbles by manually

opening this oh yeah okay yeah playing

solo now yeah yeah do we need to do that

with marbles or can i just play with

mallets mallets if you're soloing yeah i

don't need to do that with marbles you

don't have to manually open the gates no

no that's

i was going to say bs

that is bs

mallet is better right

i mean i i could do it on the top of the

machine um by pushing from the back but

um

[Music]

with mallets

um

if the if it introduces problems being

able to play the gates manually then

it's a no-go for yeah i'm gonna exclude

it for now

with mallets

um

the

vibraphone

does

not

need to be manually

playable

with marbles

contrary to previous

mmx

version the vibraphone does not need to

be annually played

only one time per year

manually playable with marbles

negative design requirements should

probably not be in here

but maybe maybe

maybe we're gonna do some clarifications

if i do this again

uh i just italic that thing

next design

whoa

um to do

22 marble gate tracks on one rod shift

them to the notes needed as per

requirement of the song

movable marble gates yeah it's the same

here if we have all 37 notes i want to

be able to use them in one song

so if if we make a note limitation i'm

going to reduce the number of

imagine if we do 11 notes we put them in

a circular pattern that would also be

cool and and if they moved when hit this

one again this beautiful one turn the

arm from 90 degrees and just make the

machine deeper

frozen tie

ah to put it

ah to put it the other direction

oh it's going to be super deep i think

so this is the same suggestion a lot of

people had the same suggestion

it would work but it's convoluted again

easy access to manual play change

between songs slightly rotated based

allow marble drops on sideways vibra

gaps to avoid collision

yeah this is the 90 degree we had a

sketch like that the other day

so these are good outside the box

footprint ideas because this is the

biggest unknown known unknown the

footprint of the machine this is kind of

a hybrid between the modular and the

all-in-one yep

uh that's actually the in-between

solution yeah i'm leaning towards that

camp a little bit you're a little bit

there yeah

why not

we can't exclude

if there's if we're able to put some

instruments on the sides or anywhere

else i mean it hurts in the artsy

heart

but if it works it works

and it would be good for sound because

it's far away from the from the snare

drum

a known unknown is the

can we pull about in cable that far

without having a lot of friction yeah we

don't know that yet

moral gate so this is the same idea with

the front catchers

by juan carbajo

vibraphone design requirement uh you got

distracted when measuring this and put

wrong value easier than what you did

state maximum bpm and note subdivision

and calculate from that for example a 16

north at

which means

zero four or four and per quarter than

200

from jme so i

think the idea here

is that this design requirement

is not bpm

sensitive

so

i think it's easier to just notice

requirement is um three in in like 300

milliseconds

so for me i think this is easier and i

think the answer was 400 but i changed

it to 300 just to have some um

so i changed it from 400 to 300 in the

stream just to have some um

resiliency and to just give a little bit

of a margin i think it's easier to note

this requirement without stating um the

bpm

right there mike perry just stated my

quote earlier they're talking about art

arch question mark this is form from

function absolutism

yeah this is this is what's funny

because it's i realized that maybe i'm

not interested in creating something

with form from function absolutely

so

that's why i'm like honestly to everyone

here i'm i'm really not sure i'm going

to build this machine and only if we can

find the design that that keeps me up at

night and that gets me so excited then i

can power through two more years of this

process

i

so this is really just an investigation

to see if

if i think this program is feasible so

when i say that i we might decide

against even doing the project i'm dead

serious

um vibraphone double and no crossing no

collisions i don't want to hide half of

the vibraphone

this takes a lot of space but it would

work

and

in the vibraphone itself i don't think

collisions are bad because as as we said

we can't play this

but we can play this

and if we need we just

take a key to play it we can't play x5s

here

that was wrong

[Music]

let's go next design next the sign

rotation on y-axis

circular chromatic uh vibrophone on

circumference of

programming wheel

you know what this would work with

mallets oh this would be beautiful with

mallet it's another shut your mouth

but it would work it's formed from

function absolutism

maybe maybe the thing to use marbles is

a design requirement

jme talking about the bpm there

ah jean-miguel expositor being the knife

you misunderstand the actual value you

measured was about 200 milliseconds

and got distracted and entered 400 which

you refined to 300 we have to get to

bottom of this maybe this is true

um

i think i have the document close by

here let's see i'm going to try to open

it first yeah hanas

here we go

let's dig into this control controversy

um it's a big controversy in the marble

universe

so

um

or was it in

[Music]

so it was from this note

539

so up here i think my zoom is not going

to work it works too well yeah a little

bit too well wait if i point it

there

so we're at five to five milliseconds

on the first note and i go to the second

note

and we're at eight five six

but this is in 181

leave leave the comment up there

i didn't do anything i'd run away

no let's see if i can find it um

so someone later told me

um

the actual value measure was about 200

milliseconds

so right now i'm getting 300

milliseconds here

between these two repeated notes

[Music]

and

someone told me that the mar machine

song was actually 145 bpm

so now

and in 145

we have 400.

so yeah i i still don't understand uh

where this confusion stems from

um but please correct me on please

please explain again

what value i measured

and

how it went wrong um

it looks i double checked now and and

it's correct

let's go for the next design in the

meantime

yeah this is beautiful

top view net it's the same net idea a

lot of people have this

it just feels like convoluted it's a

good idea from pan-pangolina's um

and this is the this

push latch

activate two gates with one pin use ball

pen mechanism

so

yeah so i saw this before i think it's

one of the sultana's most coolest videos

ever

only only question i have is how would

you implement it on the machine

um

circular vibraphone marble module ideas

rotating vibraphone bars inwards allow

use for one central funnel

that's pretty awesome

spiral bar path complicates the sign but

would allow pins to be aligned with

marble gates and can use a simple

release mechanism

you should be domain the interval

between semi

quavers semi-quavers

i don't know what that

means sixty thousand

yeah so yeah i i don't

60 000 milliseconds per minute

okay so i think you're all are like over

complicating this uh

i don't still understand here often when

i talk about timing we end up in this

discussion

so please if you

please um please explain like with more

words uh what what what you mean because

i'm not

following

16th semi quavers is 16th not just yeah

so again

like the thing that i'm the thing that

i'm checking it doesn't matter if it's

16 doesn't matter if it's eight

i'm only measuring in the dimension of

time um so yeah i'm i'm lost uh on what

you mean here

um let's see if you can unload him matt

s

um

that's a cool sketch matt s

now that the vibraphone is vital the

horizontal space under the bars can be

utilized for the

resonator pipes matt s i want to use

custom resonators from an off-the-shelf

machine even if we cut it apart

so the resonators are going to be

straight

by the way why

why not enter that as a design

requirement so let's go over to this

design requirement

um

and let's add

that

here

um

vibraphone

resonators

are used from off the shelf

vibraphone

regardless of

implementation

fix the first vibraphone please the

vibrahone

no there we go

okay next design

can you switch back no i'm reading ah

sorry

angled full-size two-row vibraphone this

is awesome

with the big yeah that's a rock concert

right there yeah we're gonna we're gonna

revisit some of these in the footprint

stream that we're planning in the future

this looks like jean-michel

yeah a circular keyboard

um

so your shake v to main has a suggestion

here the vibraphone shall be able to

play every second simic quaver

so so here

i so i really appreciate um

the engagement in this subject but what

i don't understand is why we are

discussing the bpm the only thing we

need to discuss

is

milliseconds

it's my idea

um

so the bpm has

it's not needed for this design

requirement

because we have triplets we have other

configurations

here we go

what is this

repeatability you can double the

registrator and marble drops

it is nice to have both of you back from

patrick decking nice to hear that from

you patrick programming will top view

four lines per one channel and there

will be a phase shift delta plus one and

marble fall time difference yes these

are the drop height another math person

here

um

would be paying to program but the speed

would be doable

yeah we need to solve the double marble

drops somehow that's another known

unknown

[Music]

for that stream

thanks for the sketch

roberto perry is sending cascade marbles

controlled

oh yeah

oh is it hammers again

no are they they're like dropping down

through pipes and exiting there like

yeah but there there it's a hammer

jammer it's the hammer it's mallets

i love it answer 3k

you

next design

beautiful sketch roberto the same

blanket idea from thomas k that so many

people have or the protection idea we

went through a similar here there's too

little rotation of this marble drop

because rou00 didn't

reservo didn't do this so we can't do it

by team shaffer but

a lot of people have this idea but it

would give a less stable

marble release

so we have the resonator pipes between

the two drums and that was an idea we

had in the beginning i don't think we

have to do that anymore which i'm happy

for now take it slow because you're on

the last one coming up here

okay is this the last one yeah space

enough for the resonator pipes

so

yeah

this is honestly so much fun everyone

just want to thank everyone sending in

both chats and um suggestions

thank you all for for giving these

perspectives

the big theme

of everything we have seen today

is that we're trying to solve a problem

that we don't need to have we're trying

to solve that everything is intertwined

and on top of each other we're

desperately trying to make the machine

we have on the wall behind us

it's time to move on

perhaps i don't know

time to make something that works at

least

it's

it's itching in me

when we're trying to solve when we put

everything too close to each other

and we're trying to make solutions

it's the elon musk video less dumb

design requirements

this is what i was fighting against like

constantly on on the previous machines

and i think

these two machines the more the more i'm

working on this project i think it's so

hilarious that they look so similar

and i think

for the next steps in this process for

now what i'm going to do now is that i'm

going to

allow

new dna to enter this

this project i'm going to allow for new

things

and it just creeps in me when we have to

make strange solutions because people

some parts are sitting too close to each

other

so even though we can solve all in one

machine

but the reason we want an all in one

machine is because of

dna and in identity it's not because of

function actually

and then

and here's my point

the more machine x you saw everything

everything is in the open you see every

marble being released you see every

marble

hitting the instrument

on most of the solutions we've seen

today

the marbles are obscured the release is

basically we would have an all-in-one

machine where you would see nothing

then i would prefer

at the moment i prefer a larger machine

where we don't have things on top of

each other

but

the larger machine is scaring me because

i think the programming wheel will be

big

the machine will be

just big

and i'm kind of daunted by the the

footprint of the machine so

yeah

a lot to think of but eternal gratitude

for the fantastic level of suggestions

right yeah totally brilliant and you

know what please do as the owner of

moving to

step three on your list

oh wait for it and

i'm going to

oh

thank you so so much

so yeah

i thank you all out there for this

beautiful stream

your awesome company

don't forget to subscribe and like this

video thanks for all the super chats

it's one of the only ways to support us

these days is buying our merch and the

super chats so we're so thankful for

that

and take care

everyone out there and we'll we'll see

you

on the next one absolutely thank you

everyone
