round three

fight

hello everyone

we are back after a

intense weekend

with

sir 3k who can't speak

after we went to the swedish

metal band power

um

yeah

how do you feel today sir three i have

never felt better but as you can hear my

voice is

a little bit all over the map right now

a lot of singing along yeah nice to be

with you out and watching some live

concerts and just embracing life

it was the first live concert we watched

since uh the pandemic and the energy in

the room was brilliant because everyone

had the same feeling like it's happening

again and like yeah i was i went from

the concert and it's like oh god i miss

play i'm historian i'm just playing live

brilliant energy of that band and the

whole crowd singing along chanting and

just fist pumping all the time

as you can see yeah it took a toll on me

at least but here we are we're ready to

start again

and today we are going to discuss um

marbles size and material so i'm trying

to evaluating if i even think i can make

a machine that works and

i have some new nice tools for that so

i have made a new documentation central

which you can find on

our website and in the description of of

this live stream

and

um in this documentation central you can

also see kind of some upcoming live

stream topics and

what is nice here this is like it's an

excel it's a google sheet but i made it

like a website so you can click on the

links

and you can also always go back to the

front page so it's almost like a little

excel sheet website

like um

wiki for the marble machine three yeah

and

basically on a very very high level i am

i am

this this is going to be some more

abstract weeks for you all

because we're trying to evaluate um

really how

if there is a design that i truly

believe in i've grown to become

extremely skeptic and

i look back uh

on the previous efforts

um

[Music]

i yeah i think i can show the image

there and and

the naivety i had in those machines so

basically right now i've fallen over to

the other side where i think nothing

will work

and

so uh

my plan

to combat this feeling that nothing will

work is

to use them

um

just

like think about the stuff that i can

think about

in smaller

portions and then marbles is one of

those things so also in the

documentation center we have the known

unknowns matrix

and i want to kind of

all these topics

i want to kind of investigate them and

then i want to as soon as possible

like

come to a realization that there is a

possible machine three because right now

i don't even think it's possible

honestly after this weekend how are you

not just happy about life and just get

keep this going there is no surrender

this time

well if we reach a point where it's

physically impossible then well we've

done everything we can but we're too far

away from that now

we just need to focus up and get this

sorted and you're just laughing because

h3k's

voice box

has taken some damage

it's absolutely beautiful

yeah so yeah it's it's it's

it's fun because it's like

um

yeah it's it's it's fun because it's

like tormenting me to not be

my my normal mode is like everything is

possible and i don't recognize myself in

this like nothing nothing is possible

kind of kind of mood

however

i know that it will make me kind of

happy to go into the topic of marble

research because

there will be kind of a lot of important

um aspects with the design based on two

things so

i made um i just want to say quickly

there from desert pillar anything is

possible we're on the same hype level

right here

there we go that's that is uh that is

nice from desert pillar and um

and uh han has been dealing with me the

whole day i've not been

i feel sorry for for this hype man over

here trying to hype up this this this

this um kind of mood mood whatever i

have today let's turn this around so

uh hope you're all doing great out there

we're so happy to be back um okay marvel

sizes and materials

so i've um i've prepared two decision

matrixes let's see if i can show them a

little bit better to you here

so

um

in these documents you can leave

comments try to be sparing but you can

leave comments and you can link to your

own documents there's a whole section

actually i should actually just tell you

all about that because

i love the interactions we have and i

want to have

i built this um

this whole documentation central as a

way to

so here under the contribute tab

you can see exactly how to contribute

your ideas uh to the mar machine 3

project so i kind of structured it a

little bit more during the weekend and

um

so for example

today let's take let's take an example

so we go back to marble sizes

we're going to research steel core

rubber balls today and if you want to

leave like a link or if you want to

leave something you can leave it in this

document as a comment

uh like so that's one of the way you can

contribute so let's get into what we're

gonna talk about today marvel matrix

we're going to do two decision matrixes

here so i'm going i have prepared

what material for marbles which is the

first decision matrix

and then here

we have what's size for marbles

and to fill in this i think i need to

make some

research and see what there is

and i know that there is for example

steel core rubber balls from industrial

steel core rubber balls

so yeah that's the marble matrix uh and

let's get straight into

we can see what we're going to talk

about today marble size

than marble material and then how the

marble lifting is affected by both of

these variables and then we're going to

be done

so yeah let's get into this

i feel rusty yeah it's been a while

since we've been here my voice is

definitely rusty

it will kick in a higher gear pretty

soon

is it time for humble bragging moments

right at the start of the of the stream

as well no no nothing we have to get

into the topic first okay do it then

take the wheel go

um

we'll save it as a nice easter egg

that's a nice little treat at the end of

the stream there we go what about that

with that it's it's epic it is epic

okay everyone let's let's let's get into

this um

marble size everyone

um

let's go to the decision matrix for

marble size and i'm just going to

communicate a little bit here first how

a decision matrix is used so we have the

criteria up here

and then we have this assign options

here

so i'm going to first make the weight of

the criteria

so

uh sound for a vibraphone how important

is that to one two five

um

it's pretty important for sound for

snare three sound for kick three sound

for height three sound for bass it's

actually only one because we're gonna

use the hammer jammer

so um the hammer jammer should be

playable in

whatever um

this the size is oh sorry i was on the

materials

so the size is actually

no no no this is this is good

so then we go ahead supply chain should

be like i'm gonna um hmm

that should not be here let's remove

that

uh

cost

wait the supply chain oh no sorry yeah

so

see i'm my brain hasn't started yet it's

start it's like cranking up yeah yeah

yeah yeah yeah yeah as you're at the

machine

so

uh supply chain

cost let's put three

looks two functionality five

most important one

lifting four

noise

five

marble division five as so it's very

important

machine footprint three

and then um

[Music]

now i can kind of grade the different

options

um so

um

this is going to be pretty difficult

actually

um

we're gonna do them at the same time so

that's for the

size and now i'm going to go up to the

material one

um

just want a nice little comment here

from joe

jory brahms

played my first post covet gig last

friday rocked my i believe shirt on

stage because i believe like never

before that's so cool yori what kind of

music are you playing i'm jealous about

your that you premiered your post covet

gig i'm looking for my one and a serious

question from foldy one papyrus

how on earth are you going to choose

without practical tests no way to know

how they sound without really testing

them so you're rightfully one preparers

although i do know uh

that a metal ball will sound harder than

a wood ball

and a rubber ball will sound softest

so

um

like

there are some assumptions that we can

make

with a certain level of certainty

that is not perfect as a real world

prototype with actual things but talking

about your comment i am going to try to

during this

stream to order some um some some rubber

balls

and test them yeah so um

i saw the coolest one i found

right let's see if we can open this one

in a new tab is it going to be a new tab

yes

so these are the coolest ones

um for rubber and let's see if i can

steel core rubber balls with different

coating materials so we're gonna go into

this later so we are going to test them

these kind of things

um so let's see i put the same weight

on the criteria for the

um

material one so let's um

i think during this whole live stream i

will keep filling this in

when we look at the different options

um

but i can just tell you like um

for example a pure wood ball um are you

seeing this big enough maybe i should

make this bigger for you enhance

i have to like manually enhance but it's

okay yeah we're among friends yes

yeah there we go so pure wood balls

is awesome for the hi-hat

so we put a five there so we go one two

one two three four five is the grade

and then you can see that this is

getting multiplied by the weight for a

total score of 15. yeah there are some

formula actions in this document

and steel core rubber balls is horrible

for the hyatt so there's a one

um pure rubber balls is horrible for the

hyatt so that's a one

ball bearing no wait

yeah

ball bearing steel spheres is kind of

three

it's kind of bad it's kind of two

and metal core wood marbles is a five

for the hyatt i don't even know if

metalcore wood marbles exist maybe we

have to make our own i don't want that

but we i included them for the sake of

of the discussion

um

so so um

i prefer if i could just choose

i prefer um on the hyatt to use a wood

marble like the ones i have here

um

but i don't think they weigh enough so

for the weight

the all the marbles with the

steel core are better

[Music]

noise

so noise is an interesting category ball

bearing steel spheres are bad because

they sound a lot pure rubber balls are

perfect they will sound the least steel

core rubber balls almost as good for

pure wood balls

three

metal core wood marbles

two

so

it's um

so you can see here we have

rubber balls are taking the lead fast

here oh yeah

um

we got a

a follow-up from jewelry brahms

we tend to call our music progressive

punk but it's always hard to put a label

on your own music yeah i mean there's

you know the struggle as well marcus

people we we've been all over the world

oh my best when i released uh when with

my first band we had a japanese record

label

and they released with the band was

called the tikti burn so so and they put

it like we were like pep we were like

cardboard cutout dolls in like the

japanese music store pretty proud about

that

and

do you know which stronger they put

detective debut album in

oh

it's gonna be something really strange

right

is it hip hop r b so so

because shelf space is limited in a

record store they put us in world slash

healing

world really i mean that's great

that's all there is the power yeah yeah

power of music but brilliant world slash

healing it was we

and pan flute uh

synth pads

so that's fun so i i know your struggle

it sounds fantastic it's bbp no option

for glass marbles oh

well done

glass marbles

um

[Music]

i don't know

who knows yeah who knows let's be

open-minded glassport i think we should

should write porcelain poor slain

because that's the kind of fully colored

ones

uh who who knows

they are light though

um

noise they get bad on noise one

um

so let's take a quick look at cad

because this is so abstract so we were

we were looking at this in the last

stream

with having the drums on the side and i

just added the marble cues there like

this

and i'm a little skeptical about this uh

after some pondering but this is not

what this live stream is about but i

just wanted to show like where we left

it off last week

like in the end of the stream everyone

was like so excited we like thought we

figured it out

still an option

i don't know

you love this right sir 3k i love that

we finally

ventured into the options of putting

instruments like on the side of the

machine and stuff like that that was

exciting me and a lot of people in the

audience

uh

using all that space that's available

so maybe we'll find a perfect compromise

somewhere in the middle of this yeah so

the way i'm trying to untangle this knot

of the marble machine three is to go for

things

that i know i can look at

individually and then try to get like

somewhere where where

and i think marbles is a great great

place to start

so uh yeah yoshik v tumanai shouldn't

durability also be a criteria in this

good idea um

i think

it's on under functionality okay yeah

and so for example i'm going to give

like uh i think

i think the glass marbles i'm going to

probably they would hold up really well

but i'm going to give them low score on

functionality because of that reason

yeah

so bob let's let's do that category ball

bearing steel spheres functionality is

five because they're so precise

pure rubber balls i think is three

because they're too light

weight and that i'm gonna punish that on

the sound as well for that reason

silk rubber balls f4

pure wood balls

because it's hard to get them completely

around a three

metal core wood marbles like a two

because they're hard to get i think

um just got a tip here from mike lucas

mcmaster car sifting balls is a really

good suggestion oh interesting let's

have a look at that right away sifting

balls um so i have if we go to cad we

can insert a mcmaster car

uh part here

and let's see if i can show you this

little more zoomed in like that

sifting balls

is that for like polishing machines

maybe

what is this for sorcery you're this is

why i love live streaming

what is this

wow semicolon oh they have all the

what do they have with different cores

oh here's the durometer cool so

durometer is something that i learned

from marius these values are hardness of

the rubber okay

um

and what is really really really cool

so on vibraphone um mallets

you also have

all the different hardnesses

so

if these balls would work

we could actually

we could actually order a test for each

and choose what kind of sound we want

yeah which is really really really cool

so here's harness rating and a lot of

people in chat are talking about um

probability of being a lot of friction

with rubber balls yes yes yes yes so

this is this is the

this is the big um

um

this is the big issue yeah so just to

say that just to show that you're

skating where the pack is going

in the document it says here friction

from rubber marbles creates new design

requirements compared to steel marbles

um so for example uh i would love to use

a marble pump lift

uh like

this one

um

so

i'm just gonna find it

i thought it was here in the end

there it is

so a pump lift like this

would be awesome but i think it's

complicated with um

with a lot of friction

[Music]

so

it's it's a good idea what do you think

the pump

yeah it's totally brilliant

you love the pump yeah that's a really

cool idea should be

shouldn't be too much issues with that

right

no as uh except if they're too

too much friction so that's the that's

the bad thing yeah the rubber could be

problem there

okay so what are sifting

use these polyurethane balls as seals in

pumps and check walls or let them bounce

inside of vibrating sifters for an

effective screen cleaner

they are made of polyurethane which

combines the shock absorbing qualities

of rubber with the strength of plastic

balls with a steel core are heavier than

standard balls so they are often used to

offset buoyancy buoyancy is if it can

float or not

or to reach a specific weight and that's

what we're after so let's see if we have

a steel core

option over here great see through that

a mandrake you just posted here

just saw your post on instagram it

explains a lot why hannah's voice has

gone chainsmoker's style

and yeah we weren't like it was a real

heavy metal concert all right

yeah it was fantastic we've been

listening to the non-stop since we went

to the concert

i wanted to have the steel core option

here

um

oh

here's steel cores oh i heard a little

chime here because jimmy crosby

just sent us a nice super chat and

asking us have you thought about using

different balls for different

instruments you might need to use

heavier balls for the drum slash lighter

balls for the vibra

and

yes gretzky style right yes yes

definitely so

one of my original ideas for machine 3

was to use different balls for different

instruments then we have to just catch

them or sort them somehow catch them

different catch them individually thank

you jimmy for for for the suggestion and

the support um

this is still an option so let's make a

notepad

where should i make notes should i just

do it on the ipad perhaps

no no no no no no i should do it in our

documentation central that's why i built

it

um so let's go to

[Music]

we go here

and i'm going to go

in to

here

so here i can just write everything

jamie prieto it's not the same if h3k

h3k can't say woohoo

you know what for you jamie i would try

and say whoa

it's still kind of there different

marbles for

different

instruments

um

possible

it's noted

um

[Music]

i just saw here on mcmaster car

balls with weighted core so this is

exactly kind of what i want

um

but am i reading this correctly that one

ball costs

36 dollars

one inch and one quarter these are kind

of big

uh

or is it a package of hundred

i mean

is it each

that can't be

that's super cheap

that's so expensive we're in the wrong

business harness wow we should be

mass produce marbles balls with weighted

core it's like it's a very

i'm adding it to my order

huh

let's see okay so these are extra hard

95a

um

so

the bigger the marbles are the easier it

is to see them and the easier it is to

um kind of

so let's go to i'm jumping around a

little bit to find my pace here let's go

to

um

let's go here

to the size decision matrix

and just make it clear that for looks

for the marbles anyway

um

bigger the better i i think

i'm gonna do this five four three two

on in the looks category

um

and we have another little super chat

here from aroma pearl

have you considered dense heavy wood

balls ig ligno vitae and that's cool

that's it maybe a mistake to dismiss

wood balls based on the typical light

woods available

very very very good

can you remove that window yeah i don't

like i can't see

um

so uh avron pearl very very good uh

comment i'll note it here straight away

um

i my obs setup is also lacking today

everyone yeah we have been enjoying

ourselves uh during the weekend we we're

gonna get up to scratch very quickly

here um

heavy

dance

wood balls

i think it's very very expensive the

this cool material ling nerve

lingnov vitae

let's do a quick um

quick google ling nerve vitae

wood sphere ball

um

okay

but how do you

do you think these are really true

i don't think these are from

anyway

i don't think that the weight is going

to get get there

it will be so cool though

and for the hyatt

sphere

yeah so

everyone

if you can research

if you want something to do during the

stream

you can find good links to kind of uh

and then you can just make a comment in

here

and just um

like cohen has uh made here the cohen

has suggested snooker balls which i

thought was really really cool um

like a cool outside the box thinking and

i'm a big ronnie solomon fan

as well

so if you

can find like heavy wood balls

um put that in a comment here on my

heavy dance wood balls cell in the

documentation central

um

[Music]

so

maybe i should make maybe i should make

a little bit simpler for myself maybe i

should make like little pros pros and

cons just to get so i can show you all

how i'm thinking

um so

let's see if this works now

[Music]

oh

wonderful

pros

cons

so

uh

let's start with the obvious one so

metal which we know we can get they

exist in all sizes they are super

precise super sphere spherical

metal

um

so

the cons

the cons here

comes chuck chuck bros

is noise

and sound

uh for vibraphone

and hi-hat

just wanted to add here from mike perry

what about del rin slash acetol you can

buy 2 000 of them on amazon for like 200

bucks what

delrin balls so nice to see you here

mike again um

what should i search for mike do you

think in the

uh mcmaster car database uh no so

someone suggested golf balls also

that material

golf ball is pretty cool

i mean the material at least

like

um oh maybe oh no it's going to be so

much circus i also have to make the

machine bike power then yeah bike

powered and golf balls

golf balls is uh

we could just have like a green on the

stage and see if someone hits the hole

so we could have a machine like over

here

and we're playing the music here like

yeah and we have no

funnels and instead they're just over

here and over here we have this office

putting range you know with a little

gold flag

and then we can have

so like that

and then we what we also could do hannes

yeah

um

is that we could actually mount

you're not gonna believe this we can

mount a gopro right here

[Laughter]

that is looking down into the hole i

can't believe this go no bro and we

project it like on huge screen like this

so during the concert you have only like

this big thing and then when a ball

rolls in there's gonna be like a

thunderous roar from the crowd and

everyone it starts rolling whoa

yes

as soon as i crank the machine get in

the hole

[Laughter]

that's brilliant

okay yep

i love this idea golf balls

i'm so intimidated by this project i

need to we need to laugh a bit i need to

i need i need i need golfers i'm going

to add the golf balls

to the list right interesting to know

what they're made of right

because i think they would make like the

perf perfect sound

we could get

like imagine to get uh

is it wilson or is wilson only a tennis

isn't wilson also a golf brand

yeah i think so right yeah

we have to research this i will do it

wilson golf ball

wilson sporting

wilson golf

yeah but check this i i have it

there we have it and look

wilson's staff

and there you also have the image of

wilson there

oh yeah

[Laughter]

this is the original wilson

okay so not so far from the truth

great suggestion actually i think sound

wise they would actually work

um

okay

i'm going to try to get myself together

to see um

let's see golf balls is in the list

thanks for the suggestion mike perry is

a follow-up here look up on mcmaster car

delrin ball bearings and scroll all the

way down and you will see them but they

are limited on the metric sizes but if

you find imperial equivalent equivalent

it should work

so thank you so delorean

delrin ball bearings

[Music]

oh wow look there we have water

resistance is to machine

resin balls into water resistant wear

resistant oh water resistant

that's great when we're going over the

atlantic ocean easy to machine okay this

is cool so if you want to build your own

something you can put it in a cnc and

kind of

so let's go metric

um

eight millimeter is the

largest that's what that's what mike

said

so let's go to

inches

one inch i think

i don't think they will be heavy enough

i wonder if i go to product detail that

we can see kind of the weight

friction rating very slippery

that's great

thermal stability good

for use outdoors no

um

so we know of course the

you know what we should do we should do

a cal await

i want i want them to be as heavy as

possible to make a good sound but of

course

if we lift them and if they're light our

life becomes easier as well

these would work fantastic in the in the

marble pump

yeah

this is also interesting from

it's jesus

someone mentioned that golf balls would

bounce unpredictably but you can

actually buy dimple less golf balls one

man i have never seen

i'm definitely going to

[Music]

dimple less golf balls that's fantastic

so i am um

i wanted to show you something else here

um

this is a super cool marble lifting

technique i think

moving part round

so let me just find the end here

with the demonstration

here's the demonstration

so imagine having multiple of these yeah

it will pick up the marble

turn it around

and raise it up

is what louvre did on his machine marble

comes in

move that around

and lift that one up it's pretty pretty

brilliant right yeah and you have like a

whole stack just moving upwards

yeah yeah look at that that's cool and

now

we'll get into the build

so credit to um

this video here

jim steinbrecher 41 000 views super cool

video

um

so

dimple less golf ball let's let's look

at that

golf ball

no dimple

it's like a mini

what

cool

but do wilson have them that's

that's the important one

ah no dimple golf ball i heard a little

chime there

let's see what we have here

the face in the wall

could maybe use computer mouse balls

they are 21.5 uh 21.5 millimeter in

diameter fairly cheap to an ir i

i i rc a steel core however maybe not

the easiest to source

but that's a cool idea you know

those old-timey cool mouses

super suggestion thank you so much thank

you so much i am

um

computer mouse balls i thought they were

without steel core but they're probably

definitely like steel core yeah um

so

let's get over here

it's cool with

options that i absolutely didn't think

of

um

like

this

steel core rubber balls

i think

the computer mouse balls are the same as

the steel core rubber balls that they

use some kind of industrial solution

because they were

producing a lot of of computer mouses i

guess yeah

with balls they're called a track ball

of raw pearl says ah trackball trackball

um

[Music]

and also we actually have to add to the

list

delrin

balls

mcmaster

so

hmm someone has done the math here

quentin harley one inch diameter delrin

ball will be 12 grams oh thank you

quentin

um

[Music]

one inch

12 grams

thank you because it's way too light a

16 millimeter so let's how much is an

inch in millimeter let's let's let's

check that

inch in mm

yeah so

25.4

so

um

25.4

millimeter one inch is 12 grams

and the ball bearing steel spheres

uh is 16 millimeters

was

how much was that

oh you're talking to me yeah

i mean i made all those tests

was it almost the same

i don't remember or was it six was it

like 16

yeah

we can find this out for all of this but

the most important thing is that to get

volume out of the music instruments you

need strength

you need weight

and

you need to dampen the sound as we did

on the original things with this latex

thing so you can hear the difference

[Music]

it's not as sharp

so that's why it would be so cool to not

have this on the vibraphone but to move

it to to the

to the marbles

consonator

it's asking squash balls question mark

wash balls they are made to not bounce

pretty big but perhaps they're smaller

ones right squash balls too soft i think

too soft yeah i think they're too soft

so i'm thinking about this european

supplier here for steel core rubber

balls um

[Music]

i think this is a european supplier

um

so as you can see here in the

[Music]

in the notes here there's so many

options yeah you can have

all of this

whatever that is

[Laughter]

but the ball diameters 35 starts at 35

millimeter

yeah

and for the big balls you have diameters

higher than 160 millimeter two welded

hole of steel hemispheres are used so

that's 16 centimeters so these are some

kind of

mega industrial applications i guess

yeah that's for the mmxl

yeah good one i got this right yeah

absolutely a great one

so and it also comes down to

that's probably where i should be

just diligently filling in the decision

criteria here now when we've been a

little bit everywhere

let's let's diligently fill this in

because

bigger marbles

also need wider uh marble gates yeah

so um

but let's try to do let's try to make a

guess here so we can start the

discussion uh

sound

um so the ball bearing steel spheres

is a two

pure rubber balls is a five

steel core rubber balls is a five now

pure

marb pure rubber balls is a four

pure wood balls

is a three

metal core wood marbles so three

um

and the other ones i don't know

and then it's quite interesting because

for the snare

you actually want something else i think

the steel marbles are perfect for this

knife yeah

we already know that that works

pure rubber i think would work steel

core rubber better

pure wood balls would work

maybe metal would go better

sound kick we want metal on the kick

heavy metal on the kick oh yeah

rubber balls not so good still

corruptable a little bit better pure

water ball

pure wood was bad

metacore wood marbles

a little bit better

base

i will give them five all of them

or just three so it's not differentiated

um

you can also see that the weight of that

criteria is low in the decision matrix

supply chain five on the ones we know

uh and probably three on these

um

and two on wood balls i think it's hard

to get them

and metacore woodwolf would be one it's

very hard

cost

i think ball bearings are going to be

cheapest

um so i'm just guesstimating here to

guestimating guesstimating yes um

life itself is a guesstimation sir

3k um

no no no no

i i don't feel this decision matrix is

so useful right now

uh looks let's talk about looks looks

that kill do you like the ma the look of

the metal marbles of the mormon genetics

yeah i do

kind of uh yeah yeah i do i i got so

known with them so yeah nostalgia member

berries tingles okay okay i understand

black rubber balls would be worse though

looks wise right

it's more cool with the shiny yeah yeah

the aesthetics yes

so i'm gonna put two on the rubber balls

the wood balls

for me rubber balls or wood balls is

more it is for something that's really

tiny

it's really hard for me to grasp on a

big machine but it could be cool though

i'm

i'm not against it at all three and

three

i just want to say something here that b

boot champ and some others have talked

about please keep in mind that with new

materials you're introducing a whole

world of new variables you're

invalidating nearly every lesson learned

from the mm1 and mmx think of the value

of knowledge

there is something called the lindy

effect i don't know if that's a let's

say what next um you're so right that's

dead on bible champ

lindy effect

um oh that's a crypto

let's not open that can of worms no um

so

let's

use

instead

um

knowledge or prototype

prototype

prototype

um

knowledge

so

bibo champ i think you are i i've been

thinking like

this actually worked the liquid latex we

found that out so we know that we can

solve

the hyatt um

the hyatt could work with steel marble

so

your point

is so important i'm gonna put five on

this

criteria here

and i'm going to give the ball bearings

a five because we we have experience

with them

and i'm gonna give all of the others a

one because we start from scratch

and i think

because this is so daunting and

intimidating this whole project and that

we have to use

we really have to use our experience

[Music]

and i think

with steel marbles um

[Music]

there is uh there they just have that um

advantage

marble division it's same here actually

because i think the high friction

marbles might be really hard to do

marble division on because they would

kind of get stuck in each other

so i'm gonna put a four on the things

that we know and a two on everything

else

i heard a beautiful chime there

and that means a little super chat here

from david's stream hey recommendation

why don't we test the materials plastics

versus woods versus steel slash metal

versus rubber versus maybe set up

independent lifting systems per

instrument

that's a that's a great comment thanks

david and um

we have we

uh oh i see some comments over here as

well that's nice

we have um

why don't we test the materials plastic

versus versus rubber versus maybe set up

um

[Music]

so different marbles for different

instruments possible we have we have the

command but it's of course uh

it

adds

adds the design requirement

to sort

marbles

um

so it is to use different marbles is a

com complication perhaps

but i would love to

i would love to

to do that but

if we can use one and the same then we

can have the same marble gate for

everything on the whole machine but i

think like that the kick drum wants

actually larger marbles than the hyatt

and stuff like that so

um

it's difficult

the face in the wall is back i found an

alibaba supplier that does white black

or transparent rubber coated steel balls

where do i send the link

and that's a great question right he

could use a documentation central right

and add a comment somewhere fantastic so

thank you so much for that question and

support facing the wall um i can take

this opportunity to show exactly where

i've given i've given the instructions

so if you go to the first the front page

um

here

i'm in a new browser today that's why

the window keeps traveling around on

your screen i apologize i'm

i got teased for using firefox by

certain okay because you always tease me

about safari yes we're teasing each

other now we we bullet each other to

both use chrome for today's stream and

look what happened and it just messes

things up so

on the first page there is this um

how to make written contributions and

comments page and you can actually go to

that page and here i made a step-by-step

instruction

so for the face in the wall

you

in your case how to make short comments

short helpful comments with great ideas

no long text here so one locate a cell

inside the marble machine three

documentation central that relates to

the subject of your comment

two open comment history right top

corner three add a comment keep it short

and it's in this comment where you paste

your link so this is my new

i'm trying to make our collaboration our

crazy uh over internet collaboration

between you the core

uh

fans of the modern machine three that

are here now in our in the darkest of

times when when the project is most

abstract and so hard to understand we

appreciate you so much the

the small crowd who is here with us yeah

and i really want to work together with

you because i know you're interested for

real in helping me solving this so

that's why i made this

new system with the communication um

documentation central and i hope it will

work out so that's the instructions for

how to leave a link

and yes from a brilliant username also

master caution

if you don't like the sound of steel

balls directly hitting some instruments

don't switch balls just have the balls

hit a pad that makes a melt hit the

instrument which is made of something

you like oh

oh there's a hammer jammer comment

actually yeah

so

yes

yes master caution for the base that's

exactly what we're going to do we're

going to use a hammer jammer for the

base we have it in cad

um

whoops

fusion 360. it crashed let's take a

beautiful look at us instead

i'm i have i have it back pretty soon i

think save ass

didn't crash it

okay

well back to well back to the drawing

board

so um for the bass guitar we're gonna do

exactly what you're suggesting but for

the

i think for the

for the vibraphones

i i think we want to see the marbles

hitting the vibraphone bars right we

don't want to like add

this my toothbrush

we don't want to add like a hammer next

to it

um

so

let's go to

the marble sizes again

so we're almost done with filling this

in

so

here we go

we're getting there

we're getting we're getting there one of

these days

lifting ball bearing steels first is

like easy to handle in the lift

but they're also heavy pure rubber balls

i'm scared of some of the lifts there

pure wood balls

would be probably easiest

so according to this quick and dirty

ball bearing steel spheres is winning

the tr

tried and tested

the one we have experience with

so now i can read the comments uh that

you put in during the live stream avi

perry rubber that is too grippy could

jam the machine

if they will not roll nicely together

can temperature have an impact here good

comment from avi

here is a comment from avi possible

issue denting and damage over time so

as of all the options listed these are

made to be used in the least difficult

aggressive environment on the computer

mouse

and on the winning we have a comment

um

let's see how i can show that like this

um so these are comments made in the

live stream so these are kind of a live

chat through google sheets brilliant in

here it works so well doro s tip for the

total column mark the cells go to format

conditional formatting color scale this

will then color the numbers in different

shades to see easily which one has the

highest and lowest number

that's kind of a nice thing conditional

format color scale

let's try that right away we have to

have some fun with google sheets as well

yeah that's why we're here fun

fun and hard work i'm going to

i'm going to show this in big

format

and conditional formatting

um

color scale

um

so i wanted to go

minimum value i want that to be kind of

uh yellow

max point i want to be red

midpoint orange

midpoint is a percentage

and it's orange

um

no this didn't work well

if i go blue no

this is

you smell feel the smell of

procrastination

i feel the

smell of a happy mind

that's funny

okay i should probably do percent on all

of these because i think the scale is a

little bad

why did why did why did oh yeah now it

looks no it looks good cool

and damien villa wants to throw in also

the nylon coated steel balls

nylon coated

that sounds very interesting that's from

mcmaster car i think

nylon coated

nylon

coated steel balls so what properties do

nylon have actually

[Music]

riot balls

now that's some kind of weapon thing

um

let's see if we can actually go

i'm going to try to fix my fusion 360.

do

that you know

and people are already screaming at you

about your

uh

sheet set up there your condition

shouldn't include zero

don't highlight the zeroes

uh that's why we had so bad a mix

okay

gretzky's in the chat let's fix this

because uh we we have to oblige to the

great kids satish kumar choose only

non-zero values

um

this is cool we can learn this together

um

and damien villa and they're also nylon

is durable used in caster wheels

that's a very interesting so then that's

like a pla that's like a harder plastic

around

a metal core which should probably then

not be grippy but it's that's maybe

that's this may be it

spar thier kiwi warrior nylon coated is

a good option low friction and

reasonable hardness for wear and tear ah

okay so thank you

everyone

after i fix this google sheet formatting

thing we're going to look at sizes for

steel marbles with nylon coating

maybe we're getting some maybe they can

be found in white yeah there we go

and listen to those beautiful stones

those tones means that l2m loyalty has

sent a super chat our way

i'm not an expert or anything but i have

been thinking about this for a while

what if there's a straight hole drilled

in the middle and if we can find a way

to use that to make a reliable lift that

has a very unique look

wow that's outside the box thinking

i would be a little bit scared of the

hole

being hit when it's bouncing and then

the marble bounces strange

because it's

so you mean for some the marbles would

go and kind of organize that and be

lifted up in the hole

oh that's crazy

and he also follows up here

he might be a little high

okay he's a great idea though outside

the box thinking right there l2m loyalty

in vino veritas so

we we really appreciate you being here

with us and having a nice time and for

all the love and support so yeah thank

you thank you so much

a lot of beautiful people out there

sending super chats our way that's so

nice and like the way you support us in

this since we we canceled the patreon

now it just sounds like i'm crying with

my voice

you're so beautiful out there it means

the world to us to have the support like

you're buying merch and you're giving a

super chats that's really really nice

that's what i wanted to say without

crying

and i fixed the the the chart here so

let's go from green

and maybe yellow

why is it

they are too they are so close to each

other but you're right when i excluded

this everything everything uh turned out

so much better i think this is the best

we have

no sorry

orange in the middle

here we go

wow wow

the darker red

the better option

cool cool idea thank you

let's get in to

marble material let's

go and check the nylon option

so where i wanna make my fusion 360 work

um

it is a it is a bug

when i have full screen windows and i

switch between them

and

fusion 360 disappears

so i have to fix that

and the gretsky hall of famer mike perry

says h3k you won't be the only one with

a sore throat i'm heading to a hockey

game tonight and i give it my all at

hockey games much like you guys did at

your concert

great mike perry i'm jealous of you i

want to go to more hockey games i wish

you the best

scream your lungs out you're a longtime

nhl mega fan aren't you yeah yeah yeah

i've been following for a lot of years

so mike uh what what team are you going

to root for tonight

um

yeah cad is up and running again kind of

um

so

um

let's go to mcmaster car

and let's dive a little bit deeper here

into the

steel core

rubber balls

now see sifting both what what what was

the magic word

oh

you wrote it down didn't you yeah it was

wasn't it sifting balls

sifting balls

you have to know this crazy so do we

have um

nylon here

is one of these nylon but i don't know

it

like what's the technical term for nylon

technical term you know what to do chat

help him out here

and mike perry says i'm going to boston

to watch the bruins play the toronto

maple leafs cool yeah that's gonna be a

real clash those two teams have some

history late years here

kind of epic rivalry going on since

boston eliminated maple leafs i think in

the playoffs a couple years ago

there we go there we go mike perry you

have a fellow you can talk you can talk

okay with this guy no problem

with the fountain of knowledge right

there

uh neoprene so i'm going to go and

google the tech nylon technical name

here we go

nylon

technical name

polyamide

so it's a polymer

yeah poly shatter saying

probably

so is every poly a an island the

technical term for nylon is nylon lol

polypolyamide

[Music]

could that be that

so

maybe there are some links to nylon

balls are here lino by technical term is

nylon it's a collective name for a bunch

of poly polyamides

ptfe balls

steel core rubber balls from face to

wall let's go and check this out

factory large supply high quality iron

rubber balls

night

so it it is a thing it's used for a lot

of things i think

it's a thing that is used in a lot of

things you think

love that

i i just mean that

apparently some industry needs these

things

which just means that we could find

something that would work

i wonder if this had nylon what is this

psycho dad 1604 try pa6 or pa 6.6 okay

that

let's let's

what is

pa

six

material polyamide pa6 also known as

nylon six or polycaprolactarm

it's one of the most extensively used

polyamides globally

nylon six okay cool psychothat thank you

um

[Music]

semi-crystal material

ball diameters

so i don't see in this

i don't

see

veton rubber

this is kind of like where my

this is where i should if i could like

if i was able to

like um like

my knowledge i'm so limited here like

the plastics and everything i just get

confused by it

there's

i don't really know how to find

it's such a it's such a yeah

this is like a good example it's not a

monumental task to actually

learn what what there is in just one of

the

one of the fields like just only for the

marbles but this is where we we should

get into it

um

[Music]

so

maybe i should just call these people

and ask them

on rgb

balls

so

but

everyone's who suggested nylon balls did

you see them um

steel

core

nylon

balls

oh

our friends at spakuma

awesome

so

wow they have so much

so specula has been actually sponsoring

the first machine so they're from

stockholm

uh sponsoring

there it is oh look at that

so um wow i didn't see i didn't know

about this but i love specula they've

been so fantastic with us

um so it's been like a no money deal

they just sent us that we marvel you

know that these marbles work because

they are the ones used and they have

other stuff

ceramic balls they're beautiful um

rubber balls

can supply so-called satellite balls for

polishing and here's the balls that uh

someone um

like check this out they have holes in

them like someone suggested oh yeah

um other rubber walls with steel core

and steel balls with partial or drill

through hull and drill balls with a

threaded hole

wow look at this it's from rgp balls

[Laughter]

are you connecting the dots here

so

okay so specula so this company that i

got really interested in is actually

supplying spakuma which i already have a

super nice contact at

well

the blood thickens

jesus christ honest three thousand i'm

all over the place yeah what like um

where do we go from here there's just so

many options

okay how do you feel in your mind then

uh

how much of a deal breaker is the steel

marbles just steel marbles

that actually worked

that's a good place to start

um

it's the best for the kick drum yeah

it's the best for the snare drum yeah

uh i th or maybe like uh

yeah i think it's pretty good for the

snare drum yeah

you could also have different sizes

perhaps perhaps perhaps that's kind of

annoying

um

it's

not it's not fantastic for the hyatt but

it's not a deal breaker at all yeah

um

you could even maybe maybe have

like

with with drumsticks and then

maybe maybe the

no it's not a deal breaker

yeah

this is the vibraphone that's the main

issue right

but listen to this wood ball it does

make pretty hard sound

yeah

yeah

that's i don't

and then with the vibraphone we can

solve it with these

and they're very reliable we know

we

and in a way like i would like to beat

these marvel into submission right yeah

the the the

it's so funny that they have this image

on this bearing side with the with the

mars that conquer me you can see the

army of mars here going to defeat me in

this battle yeah and i lost

we actually do have some footage

[Laughter]

so

um

look at this comment here it's from

satish kumar look out look out for under

plastic balls is bakuma for nylon balls

oh nice

um

products

uh balls

plastic balls

let me

hone in on this yes

there you have nylon yeah and delrin

also what pa we supply balls in

different plasma materials such as nylon

pa

rubber balls

so

well

my friends i think it's um you need to

order a couple of these right sending an

email to spokuma and ask if they have

steel

um

well spotted satish kumar not only are

you always first in the comment section

you're all also on point yes um

so

um

nylon pa so so there was a technical

name for nylon like someone said

um

so

i'm gonna give myself homework

yay

[Applause]

um

and i'm going to there are more comments

here now nice i'm going to uh put here

um

email spakuma regarding

steal core balls with nylon cover they

will know even if they don't have it

they will know if it exists yeah and

they can send me some technical info yep

um

so

homework

and then i'm gonna show it to my

teachers in the chat and see if i can

get a golden star next time on the next

lesson let's see um

that's kind of fun

let's talk about size

yes size yeah

and

the idea

if this would be if it would be possible

to have

two different kinds of marbles how

how great our risk is that i mean

there's

ways to sort it right

but they're gonna behave a little bit

different

so do you mean

[Music]

we saw some renders earlier on the

people is like an old is it in pinballs

or no coin machine or what is called

the old machines where they sort yeah

it's coins right in different sizes yeah

sort on size is no issue yeah okay that

is no issue but it's of course it's

another design requirement short on size

is no issue it's more the

catch separately

so

if we have

if

i thought it would be nice for this

machine to not

have to catch each instrument

individually to catch all the marbles in

one big funnel

and if we have this

um

so if we can make a sorter that sorts

them and it's fine then we can do that

it source them like on the top where it

stores them somewhere else

but if we have to catch if we can't make

a sorter then it's an issue yeah i think

so

um

it's jesus rather than sorting different

marbles could just keep them separate

isolated loops yeah isolated loops but

this uh it's hisses then we need to

catch them separate as well yeah

which which we come to the big net in

front of the vibraphone right now

oh yeah yeah the big the big fishing net

yeah to catch all the marble fish um

i just have this idea that i want the

marbles to be bigger on the moon machine

three it's

feels like okay remind me we it was a 16

we had yeah okay

so

machine 1 was 11

11.

x was 16.

so basically we just have to add five

millimeters if the

for marble machine three and someone i'm

just gonna see here oh that's perhaps a

little bit big but jerome blom share 27

millimeters is the pinball standard size

you could use off-the-shelf parts for

the handling ah interesting

tyrone blomshier

that's interesting in for jerome thank

you

i'm sorry we stole the skate olympics

gold from you guys

um

27 is the pinball 27 millimeter

pin ball

uh

standard

strange to have that as a standard

27 would be kind of awesome

it's gonna be easier to see

um

it's gonna be heavy

i like it

a real oomph to the drums

so

and for the steel balls i can just order

actually a few tests and test with the

vibraphone things i have here

um

add a lot of oomph to the drums

so

let's just go through this as well

[Music]

this is very

i'm just gonna fill this in so fast

yeah it's a little bit overkill but we

we get to think about all different

kinds so it's

serving a purpose here so for example

functionality

if i if i take in footprint in that the

machine is going to be larger the larger

the marbles are so i'm going to reverse

here i'm going to give bad grades for

large

i'm better for small

lifting should be the same actually

small get good grades large get bad

noise

um

probably equal

marble division is easier with smaller

yeah

um

small is getting a lot of points here

um so this is where the decision matrix

helps you right machine footprint was

already in here okay

um

four

three three

two then i'm going to not punish that

one so much

supply chain

i think it's a little

um a little worse wait cost yeah i

turned cost around yeah someone said it

exactly now yeah it's the wrong way

around isn't it yeah so cheaper is the

smaller

and i think it's the same with the

supply chain so

sound base

i think

20 is the best option i'm just gonna put

three on other ones

sound hi-hat i think 40 is too big

actually

30 is okay 20 is okay and 16 is less

okay

sound kick then i really want the

biggest ones

um

sound snare

40 is too big actually if we're gonna

use steel if we had plastic then 40

would be perfect for the snare so that's

also kind of an annoying

that's why i think i'm not good enough

to be able to like finish this project

because there's so many variables in

everything and my my mind goes into all

the variables in everything and you just

lose track on the like mvp the minimum

viable product

yeah

so we just get lost in the forest for

all the trees that's not the expression

is it you can't see the forest for all

the trees yeah that's that's the one

uh snare sound that's too heavy with a

steel ball for

so also this decision matrix sucks

because

i wanted to i want i didn't want to put

size and material in the same one but i

should have okay

so

three

16 is good for here i think is three and

here's two

okay so smaller so 40 millimeter is

really not a

good option let's do the conditional

formatting here that uh

the beautiful viewers have told me

here's a little mini tutorial in google

sheet for everyone in this epic live

stream all right that i just learned

from the audience when you have a range

and you want it displayed as a color

expression like this

choose your cells

go to format

i should also show that

format

choose conditional formatting

boom

and

up here

you go for the color scale

boom

and then you do some settings

um

so let's do percentage on everything i

don't know which one is best

i'm gonna do the same

as i did on the last one and then red

and i want to preview

[Music]

what

happened oh they're all red maybe

oh i can lower the percentage

um

i suck at making these fast tutorials

we're getting there

i'm so much in a mood today because i

think the marmitin won't work that's it

you just need to come around

it's a good sign to be afraid or scared

that means you're trying something new

my friend ah

say kumar cell selection is lost

you missed the cells

you were on the wrong cell

status

what's that it okay it looks better now

so awesome i

i was in the keynote okay

now i know why you couldn't see it so

let's uh let's let's let's do color

scale

oh yeah now it works thank you satish on

point as always

um

we gonna do percentages

it's just for fun

yeah

we need some fun

it was actually better when this also

was yellow

okay and here's my kelly

saying you'll get it done just remember

it's a process those who have never

failed something have never tried

something new

and i totally agree you need to be in

love with the process

everybody wanna be a beast yeah there we

go

you're the only one to score

you're not in love with the process

you should face a linking chat if they

want some motivation speech calor thank

you so much for for for that comment was

it from my kelly mike kelly hi kelly um

we were in stockholm this weekend and i

was in a restaurant with a friend and

all of a sudden someone just steps up to

me and says and and just goes towards me

and just do this no nothing else

excuse me it's going to work we don't

care how long time it takes we believe

in you nice seeing you here have a

wonderful day bye and he just went and i

was like wow it was so fun so great

right people were so people

people were so supportive and it feels

like not only you are here watching it

feels like there's so many who are maybe

not watching or like still rooting for a

picture you know sometimes you forget

that like okay there's a lot of people

out in the world who actually follows

this journey

so people come up to you in the streets

and like when we're in on a heavy metal

concert guy next to me just shook my

hand and said good luck with the catting

so funny

that was brilliant

so

dorouse gave me this tip and now we have

this color for both so according to our

sloping decision matrixes here

it's

the same ball as we used on marble

machine x it's a 16 millimeter

ball bearing steel sphere ball

that is winning

currently but um

with the caveat that i'm going to do my

homework to send an email to spekuma

about the nylon we have a lot of

links here

silicon coated

[Music]

let me see what you are seeing

here we're back to this

bread tea how heavy does the marble have

to be to not be blown of course during

windy concerts wow i didn't thought of

that alone of course

yeah we're gonna play outdoor stages

you're right about that brad

so which means that they they need to be

they need to be heavy

so

steel marbles will not be bone blown of

course

jean le belle different size marble can

easily be sorted so use several size for

several materials

yeah so what what do you mean jean or

jean is that i guess that if we want um

this is a great comment

um

if we want a

bigger ball

and this smaller ball no no no if we

want wood and steel

so the idea do i have my rubber balls

here somewhere

well we have marbles on our entire floor

they're infestated the office floors now

our biggest nightmares it's behind the

desk maybe you can see it on the webcam

i don't know

can we

no i see

a cable or two i can see behind there

you found it

i found it nice

i think i found it look at our

professional setup here especially look

at the posters in the back there

that's fold

so

i think that's a fallen warrior back

there if i understand your comment

correctly it's like if you have

if you want rubber balls for one

instrument and wood balls for another

it's hard to sort them on material but

then if you deliberately use different

sizes then you can make a ball sorter so

let me sketch the simplest ball sorter

for you right here

so that's a great point

so

it's just a classic coin machine trick

so two tracks with

widening um

area

and then

we have the green ball

and the green ball falls

into the green box

like there and then we have the red ball

that is bigger

the red ball falls

over here

so

down like this

and down like this simple huh

brutal do you get it yeah yeah

an r feel

no yeah arnie feel bored use a magnet to

sort steel from rubble balls

and that's a no-no word right now right

magnets yeah i

it's it's a little bit of a no-no word

but

um

mine uh blue magnet

versus marbles my favorite favorite

video

is it even from oh it's from caplamino

um

so there's there's a wait i'm gonna find

it here okay turn off the music yeah i'm

gonna turn the music up

and maybe we're gonna get copy

copyrighted if we show it but i just

need to show this one sequence oh yeah

this is brilliant yeah this whole video

is fantastic it's my favorite video of

all times

um

was it maybe in the beginning

oh yeah it's the first shot here

okay everyone

have you set it up for me

yes wait

wait for it

uh yep full screen or yep

do you have full screen

oh no i don't wanna because they maybe

copies copyrights claim it okay it's

better like this

um

check this out in this row up here

there are uh two forms of ball stars um

this is such a brilliant trick i can

explain

[Music]

so did you see what happened there it's

worth it it sorted all the metal balls

because of the small little magnets

there around the band and all the

porcelain went

better so

we it is a good comment it it is proven

to be a proven method to sort yeah um

but if we can avoid it i'm i would be so

happy but this video i just want to say

to caplamino magnets and marbles with 25

million views this is one of my favorite

videos of all time that's so great yeah

it's great

okay

where do we go from here honest 3 000.

let's try to summarize

um

i'm going to go through all the comments

as well um

just checking what people are writing

here

jean labelle had a wear and tear column

that's a in other words durability yeah

it's a good idea um

fibonacci weights

makes for better adjusted totals it

appropriately

proportionally balances few highly

important versus numerous low importance

okay interesting one two three five

eight

few highly important versus numerous low

okay that's a great idea for future

so louis aragone suggested um

using one two three five eight instead

that's a great idea

and this one we saw

peter kim you could use hollow plastic

balls which you can fill with whatever

material you want

hmm

that's cool idea as well

peter kim

it's not sure they need to be super

metal powder and syringe wow

but then we have to make them ourselves

that's a little tricky silicon nitrate

balls are durable and most importantly

they are black

possible issue denting in damage over

time

i just want to say this here from nina

serve by honest

one thing martin might want to take into

account is the square cube law

doubling the diameter of the bulk result

in a ball that is eight times heavier oh

that's so cool info i have to write that

down

um

we should have a

my lips are breaking because of the

weather or something no it's like oh

it's everywhere it's like sand

gets everywhere dust on the microphone

we've been gone too long yeah yeah we

took a hiatus for four days the whole

studio dusted

the square cube law the square

cube law states

that

doubling

a diameter

will make the weight of a sphere

eight times higher there we go wow

wait that's really cool which means

that a 40 millimeter steel marble

is eight times heavier than uh than a 20

millimeter one you wouldn't think that

that's cool

that was very helpful yeah

helpful high level stuff

ili gideon so here's a nice link

ptfe are less durable

you can use resin

coated wooden balls it's going to look

great and have smooth smooth surface

with low friction from enigma i think

that would look really really nice but

they're too light

and it would hold up i think

florian cg there are hollow steel or

hard metal balls as well

weight could be adjusted that way

let's have a quick look here

oh look at this

oh yeah that's a hollow one

look at these cool star wars so cool

right

it's like

never seen those before

so here's a hollowed

wow

and cleaner kit for your

house

pipe

so yeah this website is looking for the

customers who needs kugelman teal and

also there are actually these bars in

these yeah and deodorant you have there

as well oh this is every application i'm

so stupid

so fun

for your gaming controller

cool

what i don't have in me

in design and manufacturing and

engineering i make up for with bad jokes

okay yeah yeah yeah

humor you get a five out of five

okay so

um

basically

conclusion of all these marble stuff is

go with the ones we know that's the most

trusted way

and get in touch with spakuma to get

some different kinds

of coated stuff right

so

so if if anyone out there want to

aid with research

i'm going to try something here um

[Music]

research

[Music]

research gap i'm going to call it

and i'm going to put it down here

[Music]

so

what i feel like that i would really

need to know more about

is

[Music]

steel core

[Music]

nylon coated

marbles

and

steel core

rubber coated marbles so for example

if there is a page

kind of who can show you different

dimensions that also have the wall

thickness of the rubber coating and also

the dural numbers or the hardness of the

rubber coating i mean they there will be

in some list somewhere

and especially if there is a place where

we can order from from sweden because

mcmaster car is not possible

um

so

if if you already know about something

you can fill it in right down here in

the red that was a bad color let's do

this one

and let's make a nice frame

if you want to impress people in your

google sheets frame them learn how to

make frames okay

[Laughter]

i showed this to my sister and she was

like wow you really learned so much the

past years i was like yeah it was a well

invested time

sir cad a lot sir catalog is sir sir

spreadsheet a lot nowadays

so

how do we tie this into uh the big

picture and where do we go from here

let's look at our list marble lift

yeah yeah

so that's really interesting so the

marble lift

um

[Music]

i think the marble pump

is such a cool idea so this one

let me show you

the first thing i'll need is uh take

some quarter inch plywood

and i need five squares

three and a half inches square

where is the demo here

so if you didn't see this in the

beginning of the stream shout out to yim

steinbrusher

which because this is a fantastic video

what's so cool with this lift

so if you think about that lift

and if we go to sketch

[Music]

so we have

uh

no

we have the machine here and check this

out if i hold the pen

i can make an ellipse and i can make it

straighter like this wow you learned so

much spreadsheets and now sketching

and

if i just make a line here if i hold it

boom look at that wow

whoa

so imagine we had this

oh that doesn't work hang on

so that's the pump

so there's no moving parts i think it's

very silent actually

and

you can make it you just make this thing

rotate down here

and you can have all the marbles

climbing up somewhere on the side of the

machine it's also easy to position like

on the back or on the side or anywhere

um

the only thing as always with everything

is pinch points

i don't understand how they get away

from that because if the q

pinch

so it will pinch if the q runs out pinch

if

q

runs

then this thing is not practical anymore

but you can power this with the gear

train of the machine which is super cool

um

how many of these lifts would be needed

do you think

yeah and that was the cool idea we

talked about in the other

if we dragged out like this

so we can have several columns

and then you had the idea yes sir 3k

because i'm all about visual flare when

it can be it can be created easily

yes so sir 3k had if we put this on on

an off axis

that we could create a wave-like pattern

in how the marbles are moving yeah

so they don't move

you can have a little bit of

yes

which would also

spread out the load otherwise it would

be load load load load and now it's just

like

load just like um

um like eight cylinder engine

is is is it's booming at different parts

of the rotation of the shaft or how it's

working

so

like

let me just clarify what i mean

on this first disk

let's say we have four disks

so we offset the loading point

so here is the loading point at 12

o'clock and the next one is at uh three

o'clock the next one at six and the last

one at nine then you will have a

wave-like pattern of which queue

uh moves up so we have here we have four

cues and do you have you thought about

the material there are no plastic tubes

this time where it's going to be plastic

tubes it's going to be

we can have that we have acrylic

see-through tubes yeah because there's

not gonna be bands so there's no they're

not gonna get stuck that way right as

long as they are machinable uh and no

like um

no not from me

manual bending no manual banding and we

need nice fittings and straight pipes

and yeah and and then i would love

imagine just a wall

man in a wall with like

20 acrylic tubes

and just a waterfall of marble climbing

up through them that is goosebumps right

there it is pretty that is goosebumps

and i mean flare when it's easy right

[Laughter]

[Music]

it is pretty cool uh foldy one papyrus

says those sort of pumps fights against

the weight of the marble and more

importantly the frictional forces so you

need the marbles to be low friction

material yes i absolutely agree

and um

i think a conveyor belt

is the

uses less energy for that reason because

it's just

a conveyor belt

doesn't

have any friction towards the marble

it's just lifting them up

steadily and a lot of people in chat are

also uh

talking about the

uh the screw

lift on the archimedes screw yeah the

arcade screw so i can just i can just

put the archimedes screw here on the

sketch pad

i always thought it's too slow

so it's i can't really um

like this and you have a cord in the

middle here

and either you can have the marbles

sitting on one side like this or you can

have them in the screw it's used a lot

in agriculture to transport dirt and to

transport

and in the in this industry

and

i think it's very noisy

because the marbles are rolling on these

surfaces here

when when this thing is spinning around

and

but i think actually the pump is also

noisy you could kind of hear it in the

video before yeah

[Music]

um so conveyor is

it's pretty nice someone also wrote a

comment in the documentation central and

why why just why lift the marbles at all

why not just not have them fall down and

then refill between songs to have like

enough marble

to to to play the whole song which is a

good outside box suggestion and it could

be a feature on the gig you running

around with a vacuum cleaner

just collecting all the marbles i've

seen that before what do you mean you

don't like the idea i love it

i've seen it before i can see it all day

yeah

it's um

let's go to cat here

it's

it's um um

yeah i don't know what to say

oh i'm here most of my car um

[Music]

yes i think like

what i'm going to try to do is

this is the first time

since i got the idea of building the

first machine that i don't know how to

build a marble machine and i think it's

so good that i'm in this position but

i'm questioning everything

and

so

currently i'm just on the mindset that

nothing will work

so

i have to kind of

go back to the design requirements

and try to make them less dumb

and i'm going to keep on exploring the

mvp the minimum viable product and mvp

is something

it's actually a good segue i'm going to

talk a little bit about mp mvp because

that's top of mind for me right now

um

so

let's add a bonus subject in in this

stream

bonus segment

one more time one more song encore

mvp

and

it's also of course not for nothing that

minimum viable product also means most

valuable player right yeah yeah yeah

there we go so this might be the most

valuable player in

our uh

learning so what an mvp is

uh i had uh i had a page before

mvp i just heard a little tingling song

coming up there because joachim monson

asks how does pinball machines do it do

you know that martin oh and joaquim is

an accordion player nice to see you here

joakim

you would prob you would eat me for

breakfast as a gordon player i'm sure

um pinball machines um

how how they lift them yeah i don't

think yeah with

i have no clue you have no clue

but they fall down

yeah you lift them with the spring right

you push you you push them

you you

[Music]

like like you charge something and you

drop it on the mechanical one and the

ball goes up or they have they are

shooted electronically okay so there's

no lifter no lifter but if you're a sir

if if you mean if you refer to this to

sorting and then gating they use the

pacman marble gate

um which is like a half moon shape

so mvp

my minimum and good luck with accordion

by the way minimum viable product

um and this is a concept used mostly in

software

so it's mostly for digital app

so but i saw a nice tutorial uh mvp

let's do an image googling and i think i

can get it here

um

oh hannes actually found this before the

stream this is a brilliant um

a brilliant thing

if i can just

get my things together

so

the mean on the top example here

they are built making a cake so the

product is cake

and so it's in swedish so they show like

when you only have the bottom of the

cake and the cake eater is not happy as

you can see very dissatisfied with this

cake yeah yeah um it's just not a cake

yeah yeah and frosting just frosting no

no no no no no no that's bad yeah and um

and then you put a little cherry only

one cherry that's not good

but look

how happy

the smile is on the fourth step so

that's the minimum minimum viable

product

for for the cake and i'm trying to make

that but then if you look under

a little cookie

already happy yeah

a little muffin wow yum yum

about a pie

and the cake

so

can we make a little cookie marble

machine and still and still have me

being

i don't think i'm ever going to be as

happy as even the least happy smiler

here but if

if i would be

we should make like a little machine

um

[Music]

cookie

let's look at another example

um

oh so this is okay i'm getting into it

here now

so minimum viable oh this is brilliant

okay

so when you want to make a car

you don't start with the wheels

and the customer is

like

what is this you don't start with two

wheels the customer is like what is this

you have three wheels and nothing in the

customer is like this still completely

not usable and the fourth step

you have you have something that someone

can actually use

so if we look underneath you start with

a skateboard and the customers

actually not as

someone can actually use it for

something yeah yeah yeah and i think

i think that's the thing the minimum

viable product is something that

actually can be used yeah

sorry you were no no no

i forgot my bad joke keep on going

it's so sad that we never get to hear

that one um

then you have a skateboard with

something or it's like a kickback

kickback thank you

and and it's usable bike wow yeah and

motorbike

and a car yeah so

what is like the skateboard cookie

version of the marble machine three

and how can i use this minimum viable

product mindset to kind of come up with

the design requirement

that make uh the machine feel viable at

all yeah makes you at least a

regular smiley face

not the whole like whoa

[Music]

yum yum

so that's why i wanted to

to kind of go into the marble sizes and

we already have i just want to say we

have 24 comments on that things i'm so

happy for that i'm gonna go

through them off stream

so high level hannes where do you think

we go from here

we found a great comment from mark

marketing right here this is great

honestly i've had to follow countless

project management classes but seeing it

all hearing practice is very fun you see

we make project management fun

nice to hear mark marketing it's it's

i think there's a lot of people like you

out there who's going to enjoy

seeing this whole project just being

completely broken down to to

to fragments like now because when i

started cutting two weeks ago i was like

we're gonna fix this i had the same

mindset as i had in the first two

machines

and now i'm like oh we have to really

take some steps back

and make make something viable so thank

you for thank you for kind of being into

this very abstract part of the journey

and shiran the mvp is only a vibraphone

and no bass and nor percussion and let

the band play the rest yeah

that could be uh

something right

so that's a marvel played vibraphone

yeah because the vibraphone is the most

delicate thing that's the thing we're

having most trouble with right now

that's your whole decision that's what

messes with your brain right how to

solve the vibraphone the vibraphone is

the thing that is completely unsolved

for me yeah

and then

shayaran helping with saying that the

vibrant is the mvp yeah which is very

helpful sharon because that tells us

that

um

so maybe then in

maybe then

the design required the work on the

design requirements should be focused on

only focused on the vibrophone mvp

version

something like that yeah it's hard for

me to communicate this part of the

project i and i think what we're gonna

do like this week's we're gonna have

like

we tried last week's to have

very

easier to follow live streams

and i think what's going to happen this

week

is that i'm going to allow myself i'm

we're going to just let you in as flies

on our wall i think this week

um we're going to probably become even

more abstract even more hard to follow

because what we're getting into uh here

is um

it's going to be abstract and very very

loose and and very all over the place

but the beautiful audience we have here

they seem to enjoy it they're not

screaming at me that we suck or anything

they're enjoying it here good to hear

and as this fun actor says the mvp is

martin

is that is that the most valuable player

or minimum viable product both yeah okay

both

yeah so yeah so

during this whole stream i just felt

that we talked about marbles i'm tr

my plan for this stream was to try to

hone in on one subject

and i just feel

i can't really look at the parts

bit by bit

i feel i can only look at a large

picture because i i felt when i was

filling in like the decision matrix

it's it's it's too

honed

it's too zoomed in

yeah

like that's why that's why maybe like

during the whole stream myself like what

what am i actually doing and it's like

you always said like it's so difficult

with a machine like this because if you

change something somewhere it

affects 20 different things on the

machine as well yeah it's really hard to

be in really zoomed in on one subject

and don't talk about the consequences of

all the other things

right

exactly and that's why like the design

requirements that is

that should be written

sign agnostically like not about how

but why and what

um which is like the super super super

strange

piece

but i've been i've been talking to a lot

of friends this weekend a lot of artists

and creators

about

[Music]

the machine

and

thinking about like

ways for me to

[Music]

relate to the machine in ways that i

could someday actually finish it yeah

and one of the things um

barnaby dickson

shared with me um

was that like the machine will never be

feel finished because you already have a

new version in in the head

so

what i what but what i should do is to

kind of work on the sign requirement

that would give me kind of a feeling

where i think i can feel like it's

finished so for example last week a high

debate was about how many vibraphone

notes we should have yeah and i think

for me now when we talk about marbles

i just need to go back to

i think that is the

it's the next fork road decision yeah

the because i've been thinking

about if we do the 37 note vibraphone

we have a certain machine

if we do the 11 note mandrake module we

have a completely different machine yeah

um

so

you have to find that sweet spot where

you're

fine with it

yeah

so i think i'm i'm like it's like

peeling the layer of an onion like i i

need to

and i feel so

i feel really insecure about all these

design requirements i don't know

it's a lot of nice words and we worked

hard in writing starting to write them

and i learned how to learn more about

what design requirements are

um

but it's still like

the thing is hanging so much mid-air

yeah right now that's a great thing i

feel because that means a lot of options

is on the table that's what this machine

needs right

we're not immediately just building mmx2

but so how do we and that's maybe a

question for for for the true metal

warriors out there in chat right now

like how do we

do you have any ideas for like how can

we share this process with you in a way

that is

toro has a little suggestion here that i

think is

pretty great actually

doro says to sort things out to make it

a bit more visible maybe create a mind

map for it there you can also build

clusters to see what is connected to

what

that would make it visible also for the

audience not only in your genius mind

and we can like group things together so

like when we talk about okay this change

affects this group up here

that's a that's a very

nice idea doro and it's kind of maybe a

little bit what i tried to create um

with here

um like

i haven't i i feel like we're so every

all over the place and and with the

documentation central i i kind of wanted

to get get a sense of control

and maybe the mind map

a nice visual aid

maybe the mind map could be

[Music]

highest level

so tim keller had a beautiful mind map

tool

and a beautiful mind

that too

with clusters

okay that's a that's a that's a nice one

dora because that's also something that

we can look at and work on together

during the stream that

and because as soon as you go from

telling to showing

it's the bruce springsteen thing it's

that's why it's called show business

and

we

that's a that's so that's a great idea

bloomberg says

another way might be to do a flowchart

spend some time on that and see where

decisions lead you see that wonderful

friend of mine so nice to see you here

um

to do a flow chart what's a flow chart

steven what's this flow chart i'm gonna

google it

flow chart low charge

also that's

is it like a mind map

yeah that's a flow chart there we go

what decision leads to what kind of

thing yeah yeah yeah

okay so

so what would you put student you would

put kind of

um

marble size

leads to marble gates it's it's x this

is going to be a really big flow chart

this machine is

it's so complicated and big so it's all

these things explodes right away

[Music]

but some visual aid

yeah and here's some

mental aid for you from mike perry

think of the project as a funnel and you

the marble start with the general design

requirements

widest part of the funnel and then begin

to move down the funnel until you finish

the project smallest part of funnel

that's beautiful

that's that's that's really um that's

really smart

oh a little chime there

steven martin knight nine you need a

dependency table work out what part of

the system affects the most other parts

and lock that parts designs specs in

first interesting dependency table

um

i also need some

some guts to believe in myself but maybe

a dependency table can help on the way

so a dependency table

green consumes what is this

wizard

first degree dependencies

what is a dependency table

let's go let's go to

how do you create a dependency

so

work out what part of the system affects

the most other part and look look that

part design specs in first yeah i think

that's what i'm

and stephen followed up here saying for

sure it's gonna be big but not used for

smaller details maybe but for a large

flow of the project great okay that's

awesome student i have

i have kind of

so maybe maybe you can make different

ones for different areas because i have

in here i have project timeline

so i've just sketched out project

chapters and timelines so we're in

chapter one project feasibility

evaluation that sounds like a musician

at work right there

feasibility evaluation

oh yes it is the it is the title so this

is where we are

and we won't go to chapter two if

chapter one doesn't prove that we can

make something

so

but

this is a very high level for the whole

project and chapter nine my friends is

the world tour oh yeah um

so this i want to read all the chapters

in this book

especially after seeing brothers of

metal

at frieza in stockholm

but

so your your idea is good student and

yeah

i think the vibraphone

the vibraphone range and repeatability

that we talked about whole whole last

week i couldn't really make up my mind

because i'm scared of making the machine

too large

so so here so here it comes down to it

here it comes

full screen for this

either

um these are my fears

giving the full um range of the

vibraphone

and repeatability

will make the machine

physically so big

so that it becomes daunting in that way

but

the wonderful thing with allowing this

machine to finally spread out and not

look like the previous ones that failed

is that things are not in each other

yeah look by the way here's my rune from

the viking concert

i can't really see it yeah it's a rune

there no

there you have it yeah

[Music]

so the big machine

not a modular use of one big machine

um

it gives all the space for the component

needed for for that requirement so but

but i'm scared of that it's too big i'm

also scared of making an instrument that

is too similar to the previous ones we

made with only 11 notes for the

vibraphone and i'm pro all of a sudden

composing and i'm like

[Music]

and i'm making like a hit like that

um

and there's 12 notes in the melody

we're screwed then we're screwed i

actually like that melody it was like

happy wasn't it yeah

[Applause]

[Music]

it was kind of yeah nice kind of nice we

got a hit going a little sunshine for

you all there um so that's this is my

two fears too big

because i did stupid design requirements

i wanted everything and i got nothing

too small

and we made the same mistake three times

that we built something just because the

previous machine looked like that and we

didn't do form from function properly so

those are my two nightmares i don't know

which one to go for there we go that's

where we're at i don't know what to do

thanks for being here

i have no clue i'm like

sinking down in my chair now oh yeah i

have no clue what to do i have no clue

no should we look back at our previous

week we had some fun at least right

friday

saturday sunday

no no i'm i'm feeling i'm feeling so

happy that i'm not naive like before and

it's just like a new i'm not used to

this yeah because i was always excited i

always knew exactly how to do absolutely

everything i also told everyone else how

they should do their things absolutely

all that time

so this is like this uh

this uh humble that comes with the with

with wounds

from the battles cars are i think the

humbleness is probably what's

going to help us in the end but right

now it's like ah

i just don't know how to build this

machine yeah

yeah

let's go to cad let's go to camp let's

head back

no i think i think um

this is a good good point to kind of

leave everyone with this big big big

question should

should we have room

for

i want to tell new stories

i want to tell beautiful stories on this

machine

so i'm i'm just leaning very much

towards the 37 note vibrophone damien

via martin you know what kind of songs

you want to play create sound that can

that can play that thank you damian

that's that's

that's exactly you saying the same thing

i'm saying now i think

i think i need the 37

notes of the vibraphone and that is some

mvp

design requirement for me

that makes me love the project and then

everything else just have to follow from

that for example one thing that i

thought about the other day

everyone are scared for the

reprogramming time

but then i sometimes forget that we have

a band

so

let's just say that the programming

wheel is so huge so you can't remove it

easily between songs

you can reprogram it on the machine but

then you play another song while that is

happening

um

so so then you program it on the machine

state live

so

um that's a minimum viable product thing

who says that we have a design

requirement that we have to repeat songs

fast yeah um and that's real the marble

machine need to play 20 songs in a row

no we need dynamics on the concert also

the machine plays a song and then

vintage got on the band just take stage

hit up valentine just blasting valentine

why someone reprogrammed drums and then

we're on another marble machine so

whoa

there we go the who is back there who is

back

yeah i i i was thinking so because

if we're gonna make the 37 um

[Music]

3705 phone the programming wheel is

going to be big

and

i was like thinking i have to build oh

there we have the design no that was

actually a crash

so i put this as my desktop background

and every morning when i put my computer

on i met with this image and i get so

happy from it so

this is a good place actually to to um

to

take this all the way home that

i just heard a little chime here and

it's from ontario britain

and h3k with many highly coupled

components i can only manage such

complexity by separately

separately defining modules and defining

interfaces among them oh

i love this

so ontario britain this is brilliant

um

i heard things like this before

but you put it so succinctly can you

make the can you make it not go away or

does it go away after some time i will

keep it here

so i'm gonna make a sketch here in the

design requirement

[Music]

define

separate modules

so actually we got we we really got

somewhere in the stream because what i

learned from you is that the mvp is the

vibraphone yeah

and

i can start designing by approaching the

vibraphone as a module it doesn't have

to stand

away

but so it's not modular so we have three

different machines based drums

vibraphone it's just it's part of the

machine but we look at it as a

separate module define separate modules

so vibrophone i'm just putting that as

an example

never mind spelling

manage such complex by

and then

define interfaces

between modules

so a little bit when we when we started

this is brilliant ontario uh

so if we go to our old design

requirements document

this is a little bit

maybe the the framework for how we

should write the design requirements so

instead of

thinking of it as

features

as features being a module

and

known um

like

user inputs

so here we have like user inputs

um

[Music]

instead of if i think like vibraphone is

a module

and

then

the muting

levers

is a module

and the bounding cable are the

interfaces

what i think that's what what ontario

means yeah

or no interfaces made with the bowden

cables is a module and the interface is

just the connections are never mind

i guess what you mean

so

as always i've been i've been guided

towards the light

uh

by by the gods of uh of the gretzky's

yeah so thank you all for being here

through us with in this very abstract

part of the project and i mean you can

hear from my voice

that we had a great weekend it started

off with a brilliant friday

being at the gym with martin and doing

some amazing stuff and then a whole

metal concert where we just felt

the fire in our hearts were lit with the

live music brothers of metal you can

hear my voice i was screaming quite a

bit in the beginning of the stream we

promised something extra and i want to

brag to you all about my friend sir 3k

who made an amazing personal best last

friday in feet up bench press we're just

going to share that with you we've

prepared a little something for you here

to just share what this wonderful man

can do well well and there's something

there with you as well

not taking away anything from you you're

doing amazing progress as well

i mean where to humble brag but in these

streams right with these amazing people

it's just an inspirational thing it's so

fun to be around hannes and it's fun to

introduce

what you'll be doing so let's get let's

get into it

so here we have the personal best in

bench press 1.7.5 kilo no

135 there we go what raising the board

here becomes 142.5

yeah there we go wait there's more

look at that look at that stack and you

know i was i don't remember this i was

blacked out i was so focused actually

look at this

this is this is this is where i am now

we're going we're going to improve on

that over time but congratulations

hannah congratulations to you i remember

just a couple of months ago

i saw you epically fail on that wait it

was really tough for you then and now it

just flew up this time so you've done a

lot of improvements as well it's

impressive as

hell

now i i see immediately people say don't

pump alone you need a spotter and you

know there's safety racks on that so

even if i fail there's no

i can't get stuck there's safety

safety rack between

i failed a lot of times there and you

don't get stuck that's nice thing with

it

yeah so we wanted to share because it's

um that's our life nowadays it's part of

it's a part of the process here that

we're trying to do and and small

improvements on on the on the weight

number and small improvements on the

design requirements that's that's what's

going to get there one day 155 kilo with

the feet up which is more difficult is

really impressive hannes yeah thank you

so so much and i mean that's what

sparked the entire weekend imagine if i

have failed i've been i would have been

so miserable

but that was a start of an amazing

weekend it was so nice hanging out with

you my friend doing out of work stuff

just having good times yeah it's it

feels like the world is getting better

after the pandemic a little bit in that

in in that sense so

anyway as always we're humbled uh and

and and gratified by you being here

helping us out with this

and i have so much to think about but i

feel like

yeah

when i meet during this weekend when

people came up to me and said it's going

to work take your time uh i was so

touched and it's just like right now it

feels completely impossible and it's the

first time i felt that and i thought i

knew how to build the more machines

before i'm repeating myself here now but

so

thanks for being able to deal with this

uncertainty the big the big audience

hates uncertainty and surprises

and uh it feels like you are who are

here now you kind of uh love the

uncertainty

and i feel that and and i love you for

that so with that let's see you on the

next stream we don't know what it's

going to be about but it's going to be

about the beauty of it it's going to be

about maybe getting a little bit closer

to some

finishing minimum viable product let's

do this yeah yeah yeah

take care everyone

see you on the next one have a wonderful

day

[Music]
