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
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
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]
