[marble rolling]
-
Hannes: - What has been going on
in the beautiful world of the MMX this week?
-
Martin: - Yeah, it was really time to try to do
something about the sound of the marble funnels.
-
When we designed these marble funnels
it was just like trying to make them
-
look as cool as possible, you know, and
on the Marble Machine a special design requirement
-
is to leave a lot of air and space.
-
I wanted a kind of transparent funnel,
but all transparent materials are like plastic
-
and I knew I didn't want a plastic funnel,
-
so we ended up with this steel cage,
the stainless steel cage,
-
and I was like over the moon happy about
the looks and the function and everything,
-
but the big problem was the sound.
-
And the team members kept asking me:
"Is it not going to be a problem with the sound?"
-
And I was like "No, signal-to-noise,
we just choose the right microphone".
-
That is kind of a very naive
way of doing things.
-
This naivety has now caught up with me
and the sound of the stainless steel funnels
-
is actually a real problem.
-
So here you can hear a test I made with the hi-hat.
-
I recorded this with a very strange microphone,
so it sounds bad
-
but you can hear clearly
that the sound of the marble funnels
-
is actually equally strong as the sound of the hi-hat.
-
[loud metallic sound]
[louder metallic clack]
-
As I explained, you can fix this by
putting contact microphone on the hi-hat
-
or putting a microphone much closer to the
hi-hat away from the funnels and stuff like that
-
but I wanted to try to fix this problem at the source
-
by actually reducing the sound of the funnels themselves.
-
When I told about this problem we were swamped
by the idea to dip the funnels in plastidip.
-
I didn't have plastidip but Alex
ordered me these products that is like plastidip,
-
so it was time to take the funnels off the machine
-
and start to coat them with this
-
transparent rubber coating for automotive industries.
-
Today I've been making a lot of coatings
and I'm not really happy yet, but this is the funnels
-
and I want to put some more coatings
and I can really already feel
-
that the metal sound is gone.
-
Hannes: - Oh wow!
Martin: - It's more of a duller sound.
-
So right now I'm going to head over
on the Marble Machine and try this on the machine.
-
So the feel of this funnel is completely different
-
and the rubber looks great; It just created a gloss.
-
So I attached it here...
-
[less metallic thump]
-
Well...
-
[another thump]
-
Oh, it's so much better; It isn't perfect
but it's so much better.
-
[another thump]
-
Wow, did you hear that?
-
[another thump]
-
I think I can increase the layer thickness
to reduce the sound further.
-
Maybe use a real plastidip product where
I'm actually dipping the funnels rather than spraying.
-
Let's now add this that hasn't had a treatment.
-
[metallic sound]
-
[metallic sound]
-
And go back to the treated one.
-
[softer sound]
-
Wow, did you hear that,
when I was holding here?
-
[softer sound]
-
Holding there.
-
- Are you happy with it?
-
- I'm really really happy.
-
If, as you can see in the before and after,
we made a big difference
-
and it just looks actually better,
so, yeah, it's a big success actually.
-
I'm really happy this was a really annoying thing.
-
You know what Tim Keller told me the other day?
-
- What?
-
- He said that the Marble Machine X
is not sunken cost fallacy.
-
I was so happy to hear.
[chuckles]
-
- Okay, he's a good liar, though.
-
[laughter]
-
Martin: - You say goodbye to the audience, Hannes.
-
- See you later.
This was the final episode of Wintergatan Wednesdays.
-
I think we ended on a high note.
-
Well, Martin, surely the funnels weren't the only thing
you worked on this week.
-
After renovating the music studio I'm back as
project manager for the Marble Machine X project.
-
I'm working on these yellow tasks
of populating the task list
-
and the task list looks like this;
-
And we have quite a lot of fun things going on.
-
Lucas is working on a lifting solution
-
which we're gonna put some
-
bolts in the legs of the Marble Machine to make it
easy for me to move it around when recording video;
-
Richard is working on these cyber capos.
-
Here's the inbound ramps, was a discord suggestion,
-
they're gonna make it silent
when the marbles go into the plywood gear here.
-
When I'm looking at the issues list
I've been color coding things,
-
so the yellow is the ongoing tasks,
the green is the finished tasks,
-
all these green ones over here is me
fixing the music studio.
-
The blue issues is everything that's going to be solved
with the marble divider redesign.
-
I have realized that I almost delegated
everything that I can delegate right now
-
so that's quite an achievement for the PM butterfly
and now I need to design some stuff in CAD
-
before I can delegate it too for manufacturing.
-
So today I'm gonna do exactly
that with this pink task here;
-
Issue number 60: Conveyor belt intro.
-
So let's head over to Fusion 360
and look at the old design.
-
As you can see there's a lot of parts
and when I tried this design on the machine
-
I realized this is way over complicated.
-
We don't need to constrain the marbles
as hard as I thought; That just causes issues.
-
We can just basically make an open tray
for the conveyor belt to pick up marbles in
-
So I can delete all this.
-
But I don't want to redesign this from scratch,
-
I'm just going to basically butcher the old design.
-
You can see the little triangle I get there?
It's because I'm in the middle of the line.
-
So I'm just gonna add a little here...
-
Let's add 40 millimeters...
-
See, I'm locking onto the line there
-
and that means the spline is tangential with the side.
-
So I'm happy with that shape
-
and then I can just cut and take mirror
-
and I'm gonna choose
this line and this line,
-
I'm gonna de-choose this line
and then I'm gonna choose this line as a middle line
-
and there you see it's mirroring on the other side,
so now we have a symmetric shape.
-
I have an 18 millimeter opening of the PMMA pipe.
-
I want this opening of the PMMA pipe
-
to be tangential with the level of the floor
-
like that.
-
Boom!
-
And then if I make a 22 millimeter,
which is outer diameter,
-
and I x-ed that so it's
not a construction line anymore.
-
If I then show the body
I can then make an extrusion
-
and then we have a cut-out for the pipe so,
minus 20 millimeters,
-
that's the entry of the pipe.
-
This whole thing is hurting my CAD pride now.
-
I'm gonna start over next to it...
-
"New component", yes, I'm gonna throw you away,
-
"Size of a marble", 15.875...
-
Boom!
-
This, the thickness of the acrylic, 15.
-
So cute they are, the marbles they are
waiting to be picked up by the conveyor belt!
-
And I want this angle to be...
-
eight degrees.
Boom!
-
And I want this little detent to be a little bit longer,
-
and I can go back to my plane
-
and do it five degrees instead.
-
Did you see how that little detent became longer
-
because I'm, like, reducing the angle of the plane?
-
So now again I can cut the opening for the PMMA pipe
-
and now we're gonna make a top side of this.
-
We don't need six screws, Martin.
-
That's typical Martin-2019 idea.
-
Four screws is enough
-
and the acrylic stock is 15,
so we take this 15 millimeter straight up,
-
so I actually cut a little bit here
on the underside so we could clamp
-
with the screws on this PMMA pipe.
-
You will see the PMMA pipe from the top;
-
It's actually pretty cool.
[mouse clicks]
-
Here you can clearly see
the cutout I made for the clamping.
-
I think that feature is really nice in this design.
-
Are you ready for the final comparison?
This is Martin Molin à la 2019.
-
This is Martin à la 2020. [chuckles]
-
No complicated top side
-
and we're not like trying to constrain the marbles
more than they need to be constrained.
-
I've noticed that the marbles are behaving great
-
if they're just free in a tray
the conveyor belt is picking them up.
-
This part broke when the conveyor belt broke.
-
So now I'm just gonna upload this step file into dropbox,
-
put the dropbox link in a project chapter,
-
send it off to the octopus
-
and in a couple of weeks this part will arrive to me
manufactured, hopefully, and it will work. Yeah!
-
And I put it on Discord and Alex CNC
accepted the task.
-
Alex CNC has made all the acrylic parts
with flame polishing and stuff, so
-
I was very happy.
-
Hannes: - And speaking about the e-team:
I've been talking to Christof, a new face in the team.
-
What are you currently working on,
on the machine itself?
-
Christof: - Mainly I'm responsible for the sound wiring,
-
which is the pure wiring.
So I'm not picking a microphone,
-
that's easier if you're close to the machine,
that's Martin,
-
but getting all the microphones that are
already on the machine
-
and that are coming to the machine,
ready and wired in a neat manner
-
so no cables hanging into gears that are moving
-
and no cables being ripped off or
melted while somebody is welding.
-
Exactly how the cables are routed
-
will come a little later and
it's not important right now.
-
So, we're making a sound central,
how Martin calls it,
-
in the back of the MMX,
that everything will be connected to.
-
But how we keep the
-
cables out of moving gear is a decision
that we much easier can make on the machine,
-
so we wait with that
until we can all meet in France and decide that.
-
One of my different projects is a holder
for microphones under the vibraphone.
-
It has to be flexible
-
because we don't know exactly how the
vibraphone resonator pipes are going to look in the end.
-
They might be open or closed, short or
long, bent or straight,
-
that is still very much up for debate.
-
And one of those flexible solutions is
spanning a net
-
close to the resonator pipes and just hanging
-
several microphones in that net.
-
So I built a frame,
-
and what I used is a carbon fiber pipe
and rubber connectors that you can
-
easily buy off the shelf,
that are normally used for kites.
-
And because they're rubber,
you can just slide things along to
-
stretch the net a little more or less
and then you have...
-
exactly the type of net you want.
-
The double layer net...
gives us the opportunity
-
to angle a mic in a certain way by just
using different holes in the
-
top and the bottom net.
-
So the hope is that this net is dampening enough
-
so that all the noise that is inside the frame of the MMX
will not transfer to the microphones,
-
and they will only catch
sound that's in the air, not in the frame.
-
Martin: - Ding ding-a-ding-a-ding!
Oh, the mail just arrived with Christof's package.
-
Hannes: - Oh my god, how exciting! Live!
Martin: - Thank you!
-
Whoa! Check this out!
- Wow, paper!
-
- Wow, these are so cool.
Carbon fiber sticks,
-
oh, beautiful elastics.
I've never seen so cool elastics.
-
I think with this I can build any frame
I want and...
-
I love all the pieces you sent Christof!
So awesome!
-
Thanks for being part of the MMX
e-team and deliver so cool stuff.
-
- Christof delivers.
- Christof delivers big time.
-
Thank you Christof, awesome!
-
Speaking about people who delivers big time:

-
- It's so cool!
I only have one big critique on that video:
-
Where was my name in the stars?
-
- What? He used the list in youtube
-
about contributing and you didn't help
at all with the Marble Machine X design, Hannes.
-
- Oh, sorry! Okay yeah, well that's true.
[laughter] It's on me.
-
- You were just there, like drying up my tears
-
when I wanted to stop with the first machine
-
and you have been there ever since.
-
But apparently Benton Collins doesn't care about that.
- No, he doesn't care about me.
-
- Fantastic editing and I love the...
- The floating angle grinder!
-
- Thank you Benton,
really, really awesome!

-
[another melody]
-
WOW! Okay, this is fantastic!
-
And you know what?
-
If you just put some more dampening
material in the box
-
you have like a perfect sound
where the marbles are falling.
-
Look at me, like teaching other people
how to stop the marbles from sounding,
-
while I'm like failing exactly with that thing
in the same video.
-
Przemek Pytel, I am really impressed by what you did here.
-
I think I never heard a Marble Machine
being able to play so fast and so good
-
and I think you just absolutely pull this one off.
-
Thomas: - Hi Hannes and Martin.
-
The little sister of the MMX:
-
The brain, arduino nano
with power transistors and keyboard.
-
The mechanical control unit for the marbles
and the solenoids.
-
The marble divider...
-
- Cool!
-
- The material
-
Wow.
-
- and the glockenspiel.
[plays short melody]
-
- Wow! Thomas, thank you so much for showing this,
this is awesome!
-
The whole design of this machine,
Thomas, is like how I wished
-
I had designed my machine if I designed it
completely in CAD from the beginning.
-
Everything looks so clean and things just working...
-
Wow Thomas, that was really impressive
-
and I just searched for Exergia and I
found his youtube channel
-
and Thomas has like
invented a candle car kit, thermal generator...
-
There is so much cool stuff.
-
Kurbel Generator...
-
So this candle car looks amazing,
-
like a car that
burns on a candle, I guess,
-
so check out Exergia's youtube channel.
-
Awesome Thomas, thank you so much for sending it in.
