0:00:08.060,0:00:12.400
[funnel sound test]

0:00:16.000,0:00:19.700
Hannes: - What has been going on[br]in the beautiful world of the MMX this week?

0:00:19.700,0:00:23.680
Martin: - Yeah, it was really time to try to do something about

0:00:23.680,0:00:26.240
the sound of the marble funnels.

0:00:26.460,0:00:29.599
When we designed these marble funnels[br]it was just like trying to make them

0:00:29.600,0:00:34.680
look as cool as possible, you know, and[br]on the Marble Machine a special design requirement

0:00:34.680,0:00:37.200
is to leave a lot of air and space.

0:00:37.200,0:00:42.960
I wanted a kind of transparent funnel,[br]but all transparent materials are like

0:00:42.960,0:00:48.320
plastic and I knew I didn't want a[br]plastic funnel so we ended up with this

0:00:48.320,0:00:53.440
steel cage, the stainless steel cage,[br]and I was like over the moon happy about

0:00:53.440,0:00:58.300
the looks and the function and everything,[br]but the big problem was the sound.

0:00:58.300,0:01:03.359
And the team members kept asking me: [br]"Is it not going to be a problem with the sound?"

0:01:03.359,0:01:07.680
And I was like "No, signal-to-noise, we[br]just choose the right microphone".

0:01:07.680,0:01:12.480
That is kind of a very naive[br]way of doing things.

0:01:12.480,0:01:16.860
This naivety has now caught up with me[br]and the sound of the stainless steel funnels

0:01:16.860,0:01:19.240
is actually a real problem.

0:01:19.680,0:01:22.320
So here you can hear a test I made with the hi-hat.

0:01:22.320,0:01:25.840
I recorded this with a very strange microphone, so it sounds bad

0:01:25.840,0:01:29.240
but you can hear clearly that the sound of the marble funnels

0:01:29.240,0:01:33.120
is actually equally strong as the sound of the hi-hat.

0:01:33.320,0:01:37.060
[loud metallic sound]

0:01:45.040,0:01:48.960
As I explained, you can fix this by[br]putting contact microphone on the hi-hat

0:01:48.960,0:01:52.640
or putting a microphone much closer to[br]the hi-hat away from the funnels and

0:01:52.640,0:01:55.920
stuff like that but I wanted to try to fix this problem

0:01:55.920,0:02:01.200
at the source by actually reducing the[br]sound of the funnels themselves.

0:02:01.200,0:02:05.620
When I told about this problem we were swamped by the idea

0:02:05.620,0:02:08.080
to dip the funnels in plastidip.

0:02:08.460,0:02:13.280
I didn't have plastidip but Alex[br]ordered me these products that is like plastidip,

0:02:13.280,0:02:16.640
so it was time to take the funnels off the machine

0:02:16.640,0:02:19.440
and start to coat them with this

0:02:19.440,0:02:23.120
transparent rubber coating for automotive industries.

0:02:23.120,0:02:28.680
Today I've been making a lot of coatings[br]and I'm not really happy yet, but this is the funnels

0:02:28.680,0:02:33.100
and I want to put some more coatings[br]and I can really already feel

0:02:33.780,0:02:35.420
that the metal sound is gone.

0:02:35.420,0:02:40.800
Hannes: - Oh wow![br]Martin: - It's more of a duller sound.

0:02:40.800,0:02:45.599
So right now I'm going to head over on[br]the Marble Machine and try this on the machine.

0:02:45.599,0:02:48.720
So the feel of this funnel is completely[br]different

0:02:48.720,0:02:52.440
and the rubber looks great; it just created a gloss.

0:02:52.920,0:02:55.360
So I attached it here...

0:02:55.580,0:02:56.540
[less metallic thump]

0:02:58.960,0:02:59.880
Well...

0:03:00.540,0:03:01.540
[another thump]

0:03:02.720,0:03:07.380
Oh, it's so much better; it isn't perfect[br]but it's so much better.

0:03:07.720,0:03:08.600
[another thump]

0:03:09.520,0:03:11.340
Wow, did you hear that?

0:03:11.560,0:03:12.380
[another thump]

0:03:14.080,0:03:18.400
I think I can increase the layer[br]thickness to reduce the sound further.

0:03:18.400,0:03:23.980
Maybe use a real plastidip product where I'm actually dipping the funnels rather than spraying.

0:03:26.320,0:03:29.400
Let's now add this that hasn't had a treatment.

0:03:30.040,0:03:31.080
[metallic sound]

0:03:32.800,0:03:33.880
[metallic sound]

0:03:41.200,0:03:43.300
And go back to the treated one.

0:03:45.980,0:03:46.920
[softer sound]

0:03:47.700,0:03:50.280
Wow, did you hear that,[br]when I was holding here?

0:03:51.320,0:03:52.280
[softer sound]

0:03:55.920,0:03:58.280
Holding there

0:04:14.720,0:04:15.900
- Are you happy with it?

0:04:16.440,0:04:18.020
- I'm really really happy.

0:04:18.320,0:04:22.639
If, as you can see in the before and after, [br]we made a big difference

0:04:22.639,0:04:28.720
and it just looks actually better, [br]so, yeah, it's a big success actually.

0:04:28.720,0:04:31.387
I'm really happy this was a really[br]annoying thing.

0:04:31.387,0:04:33.560
You know what Tim Keller told me the other day?

0:04:34.100,0:04:35.020
- What?

0:04:35.980,0:04:38.900
- He said that the Marble Machine X is not sunken cost fallacy.

0:04:39.860,0:04:41.080
I was so happy to hear.

0:04:41.500,0:04:45.120
- Okay, he's a good liar, though.

0:04:45.560,0:04:47.560
[laughter]

0:04:49.600,0:04:52.540
Martin: - You say goodbye to the audience, Hannes.

0:04:52.540,0:04:57.160
- See you later. [br]This was the final episode of Wintergatan Wednesdays.

0:04:58.120,0:04:59.660
I think we ended on a high note.

0:05:00.680,0:05:05.380
Well, Martin, surely the funnels weren't the only thing you worked on this week.

0:05:06.000,0:05:10.020
After renovating the music studio I'm back as project manager for the Marble Machine X project.

0:05:10.020,0:05:14.400
I'm working on these yellow tasks of populating the task list

0:05:14.400,0:05:19.700
and the task list looks like this; and we[br]have quite a lot of fun things going on.

0:05:20.120,0:05:23.028
Lucas is working on a lifting solution

0:05:23.028,0:05:28.080
which we're gonna put some bolts in the legs of the Marble Machine

0:05:28.220,0:05:31.000
to make it easy for me to move it around when recording video;

0:05:31.100,0:05:33.560
Richard is working on these cyber capos.

0:05:33.560,0:05:36.800
Here's the inbound ramps, was a discord suggestion,

0:05:36.800,0:05:41.480
they're gonna make it silent when the marbles go into the plywood gear here.

0:05:41.480,0:05:44.520
When I'm looking at the issues list I've been[br]color coding things,

0:05:44.680,0:05:49.440
so the yellow is the ongoing tasks,[br]the green is the finished tasks,

0:05:49.440,0:05:53.000
all these green ones over here is me[br]fixing the music studio.

0:05:53.220,0:05:59.000
The blue issues is everything that's going to be solved with the marble divider redesign.

0:05:59.520,0:06:04.160
I have realized that I almost delegated[br]everything that I can delegate right now

0:06:04.160,0:06:10.620
so that's quite an achievement for the PM butterfly[br]and now I need to design some stuff in CAD

0:06:10.620,0:06:13.340
before I can delegate it too for manufacturing.

0:06:13.340,0:06:19.120
So today I'm gonna do exactly that with this pink task here; issue number 60: conveyor belt intro.

0:06:19.440,0:06:24.240
Let's head over to Fusion 360 and look at the old design.

0:06:24.240,0:06:28.300
As you can see there's a lot of parts[br]and when I tried this design on the machine

0:06:28.480,0:06:31.520
I realized this is way over complicated.

0:06:31.520,0:06:36.720
We don't need to constrain the marbles[br]as hard as I thought; that just causes issues.

0:06:36.720,0:06:41.620
We can just basically make an open tray for the conveyor belt to pick up marbles in

0:06:41.840,0:06:46.880
I can delete all this but I don't want[br]to redesign this from scratch,

0:06:46.880,0:06:51.120
I'm just going to basically butcher the[br]old design.

0:06:51.120,0:06:55.820
You can see the little triangle I get there? [br]It's because I'm in the middle of the line.

0:06:55.820,0:06:58.080
So I'm just going to add a little here...

0:06:58.080,0:07:02.540
Let's add 40 millimeters...[br]See, I'm locking onto the line there

0:07:02.540,0:07:05.580
that means the spline is tangential with the side

0:07:05.580,0:07:09.480
so I'm happy with that shape and then I can

0:07:09.480,0:07:13.440
just cut and take mirror and I'm gonna

0:07:13.440,0:07:18.000
choose this line and this line, [br]I'm gonna de-choose this line

0:07:18.000,0:07:19.880
and then I'm gonna choose this line as a middle line

0:07:19.880,0:07:24.980
and there you see it's mirroring on the other side, [br]so now we have a symmetric shape.

0:07:24.980,0:07:29.040
I have an 18 millimeter opening of the PMMA pipe.

0:07:29.260,0:07:31.680
I want this opening of the PMMA pipe

0:07:31.680,0:07:35.300
to be tangential with the level of the floor[br]like that.

0:07:35.300,0:07:40.480
Boom! And then if I make a 22[br]millimeter, which is outer diameter,

0:07:40.480,0:07:44.000
and I x-ed that so it's[br]not a construction line anymore.

0:07:44.000,0:07:48.060
If I then show the body I can then make[br]an extrusion

0:07:48.060,0:07:52.400
and then we have a cut-out for[br]the pipe so, minus 20 millimeters,

0:07:52.400,0:07:54.587
that's the entry of the pipe.

0:07:54.587,0:07:59.540
This whole thing is hurting my CAD pride now.

0:07:59.540,0:08:00.879
I'm gonna start over next to it...

0:08:00.880,0:08:07.340
"New component"- yes, I'm gonna throw you away,

0:08:07.340,0:08:11.320
"Size of a marble" - 15.875...[br]Boom!

0:08:11.320,0:08:14.260
This, the thickness of the acrylic, 15.

0:08:15.280,0:08:19.560
So cute they are, the marbles they are[br]waiting to be picked up by the conveyor belt!

0:08:20.280,0:08:24.980
And I want this angle to be...[br]eight degrees. Boom!

0:08:24.980,0:08:28.560
And I want this little detent to be a little bit longer,

0:08:28.560,0:08:31.500
and I can go back to my plane

0:08:31.500,0:08:34.240
and do it five degrees instead.

0:08:34.240,0:08:37.360
Did you see how that little detent became longer

0:08:37.360,0:08:40.399
because I'm, like, reducing[br]the angle of the plane?

0:08:40.399,0:08:44.399
So now again I can cut the opening for[br]the PMMA pipe

0:08:44.399,0:08:47.426
and now we're gonna make a top side of[br]this.

0:08:47.426,0:08:49.160
We don't need six screws, Martin.

0:08:49.160,0:08:54.440
That's typical Martin-2019 idea.

0:08:54.440,0:08:59.920
Four screws is enough and the acrylic[br]stock is 15, so we take this 15

0:08:59.920,0:09:03.680
millimeter straight up,[br]so I actually cut a little bit here

0:09:03.680,0:09:08.399
on the underside so we could[br]clamp with the screws on this PMMA pipe.

0:09:08.399,0:09:13.680
You will see the PMMA pipe from the top;[br]it's actually pretty cool.

0:09:13.680,0:09:17.519
Here you can clearly see the cutout I made for the clamping.

0:09:17.520,0:09:20.320
I think that feature is really nice in[br]this design.

0:09:20.320,0:09:22.040
Are you ready for the final comparison?

0:09:22.040,0:09:28.080
This is Martin Molin à la 2019.

0:09:28.080,0:09:35.480
This is Martin à la 2020.[br]No complicated top side

0:09:35.480,0:09:40.080
and we're not like trying to constrain the marbles[br]more than they need to be constrained.

0:09:40.080,0:09:42.740
I've noticed that the marbles are behaving great

0:09:42.740,0:09:46.140
if they're just free in a tray the conveyor belt is picking them up.

0:09:46.140,0:09:48.580
This part broke when the conveyor belt broke.

0:09:48.580,0:09:52.100
So now I'm just gonna upload this step file into dropbox,

0:09:52.100,0:09:54.120
put the dropbox link in a project chapter,

0:09:54.120,0:09:57.839
send it off to the octopus[br]and in a couple of weeks this part will

0:09:57.839,0:10:03.200
arrive to me manufactured,[br]hopefully, and it will work. Yeah!

0:10:03.200,0:10:07.080
And I put it on Discord and Alex CNC[br]accepted the task.

0:10:07.080,0:10:11.200
Alex CNC has made all the acrylic parts with flame polishing and stuff, so

0:10:11.200,0:10:12.400
I was very happy.

0:10:12.400,0:10:15.120
Hannes: - And speaking about the[br]e-team:

0:10:15.125,0:10:17.357
I've been talking to Christof, a new face in the team.

0:10:17.357,0:10:21.008
What are you currently working on, [br]on the machine itself?

0:10:21.008,0:10:23.760
Christof: - Mainly I'm responsible for the sound wiring,

0:10:23.760,0:10:27.585
which is the pure wiring. [br]So I'm not picking a microphone,

0:10:27.585,0:10:30.480
(that's easier if you're close to the machine, that's Martin),

0:10:30.480,0:10:34.640
but getting all the microphones that are[br]already on the machine

0:10:34.640,0:10:39.271
(and that are coming to the machine) [br]ready and wired in a neat manner

0:10:39.271,0:10:43.020
so no cables hanging into[br]gears that are moving

0:10:43.020,0:10:45.440
and no cables being[br]ripped off or

0:10:45.440,0:10:47.660
melted while somebody is welding.

0:10:47.800,0:10:50.160
Exactly how the cables are routed

0:10:50.160,0:10:53.680
will come a little later and it's not[br]important right now.

0:10:53.680,0:10:57.760
So, we're making a sound central (how[br]Martin calls it)

0:10:57.760,0:11:02.400
in the back of the MMX, that everything[br]will be connected to.

0:11:02.400,0:11:07.360
But how we keep the[br]cables out of moving gear is a decision

0:11:07.360,0:11:10.540
that we much easier can make on the machine,

0:11:10.620,0:11:15.720
so we wait with that [br]until we can all meet in France and decide that.

0:11:15.723,0:11:18.800
One of my different projects is a holder

0:11:18.800,0:11:21.460
for microphones under the vibraphone.

0:11:21.460,0:11:25.760
It has to be flexible[br]because we don't know exactly how the

0:11:25.760,0:11:29.120
vibraphone resonator pipes are going to[br]look in the end.

0:11:29.120,0:11:34.040
They might be open or closed, short or[br]long, bent or straight,

0:11:34.040,0:11:36.720
that is still very much[br]up for debate.

0:11:36.720,0:11:41.040
And one of those flexible solutions is[br]spanning a net

0:11:41.040,0:11:44.320
close to the resonator pipes and just[br]hanging

0:11:44.320,0:11:46.618
several microphones in that net.

0:11:46.618,0:11:47.839
So I built a frame,

0:11:47.839,0:11:52.240
and what I used is a carbon fiber pipe[br]and rubber connectors that you can

0:11:52.240,0:11:56.399
easily buy off the shelf (that are[br]normally used for kites).

0:11:56.399,0:12:01.519
And because they're rubber, [br]you can just slide things along to

0:12:01.519,0:12:06.000
stretch the net a little more or less[br]and then you have...

0:12:06.000,0:12:08.316
exactly the type of net you want.

0:12:08.316,0:12:13.760
The double layer net... gives us the[br]opportunity

0:12:13.760,0:12:18.240
to angle a mic in a certain way by just[br]using different holes in the

0:12:18.240,0:12:19.900
top and the bottom net.

0:12:19.900,0:12:28.240
So the hope is that this net is dampening enough[br]so that all the noise that is inside the

0:12:28.240,0:12:33.200
frame of the MMX will not transfer to the microphones,

0:12:33.200,0:12:39.440
and they will only catch[br]sound that's in the air, not in the frame.

0:12:39.440,0:12:45.120
Martin: - Ding ding-a-ding-a-ding! [br]Oh, the mail just arrived with Christof's package.

0:12:45.120,0:12:50.240
Hannes: - Oh my god, how exciting! Live!

0:12:50.240,0:12:54.600
- Whoa! Check this out! [br]- Wow, paper!

0:12:54.600,0:13:01.640
- Wow, these are so cool.[br]Carbon fiber sticks,

0:13:02.120,0:13:05.040
oh, beautiful elastics. [br]I've never seen so cool elastics.

0:13:05.040,0:13:09.440
I think with this I can build any frame[br]I want and...

0:13:09.440,0:13:13.060
I love all the pieces you sent Christof![br]So awesome!

0:13:13.060,0:13:18.520
Thanks for being part of the MMX[br]e-team and deliver so cool stuff.

0:13:19.180,0:13:23.560
- Christof delivers. [br]- Christof delivers big time.

0:13:23.560,0:13:25.333
Thank you Christof, awesome!

0:13:25.340,0:13:28.860
Speaking about people who delivers big time:

0:13:28.860,0:13:37.920
[singing simply to rhythmic chimes][br]♪ C-o-m-m-u-n-i-t-y C-o-r-n-e-r ♪

0:13:37.940,0:13:41.080
♪ Community Corner ♪

0:13:41.080,0:13:42.380
- Wow!

0:13:42.380,0:13:45.520
[thumping bass beat]

0:13:45.520,0:13:48.360
[compressed voice over added][br]"There's something new under heaven."

0:13:48.380,0:13:51.500
"Something that has never been there before."

0:13:51.560,0:13:53.300
"Ladies and gentlemen,[br]we are bringing you..."

0:13:53.300,0:13:59.900
"...the most important story of this century."

0:14:00.800,0:14:03.200
Martin: - Yeah!

0:14:05.280,0:14:07.080
Wow!

0:14:08.820,0:14:10.980
[music fades]

0:14:12.480,0:14:18.399
What? It's fantastic! [br]Why is the water purple in the end?

0:14:18.399,0:14:22.656
And Benton Collins Photography[br]may... is maybe aware of

0:14:22.656,0:14:26.560
that ice is my favorite thing, [br]that I drink everything with ice.

0:14:26.560,0:14:31.187
- It's so cool! [br]I only have one big critique on that video:

0:14:31.187,0:14:34.000
Where was my name in the stars?

0:14:34.000,0:14:39.279
- What? He used the list in youtube[br]about contributing and you didn't help

0:14:39.279,0:14:41.519
at all with the Marble Machine X design, Hannes.

0:14:41.519,0:14:44.640
- Oh, sorry! Okay yeah, well that's true.[br][laughter] It's on me.

0:14:44.640,0:14:47.380
- You were just there, like drying up my tears

0:14:47.380,0:14:49.700
when I wanted to stop with the[br]*first* machine

0:14:49.700,0:14:51.601
and you have been there ever since.

0:14:51.601,0:14:56.585
But apparently Benton Collins doesn't care about that. [br]- No, he doesn't care about me.

0:14:56.585,0:14:59.780
- Fantastic editing and I love the... [br]- The floating angle grinder!

0:14:59.780,0:15:03.460
- Thank you Benton, [br]really, really awesome!

0:15:03.480,0:15:07.780
[fast glockenspiel melody,[br]accompanied by mechanical noise][br][♪ J S Bach: Bouree in E-minor BWV 996 ♪]

0:15:18.740,0:15:22.660
[another melody]

0:15:27.000,0:15:31.020
WOW! Okay, this is fantastic!

0:15:31.080,0:15:32.420
And you know what?

0:15:32.420,0:15:36.620
If you just put some more dampening[br]material in the box

0:15:36.623,0:15:41.680
you have like a perfect sound [br]where the marbles are falling.

0:15:41.680,0:15:46.000
Look at me, like teaching other people[br]how to stop the marbles from sounding,

0:15:46.000,0:15:51.803
while I'm like failing exactly with that thing [br]in the same video.

0:15:51.803,0:15:58.240
Przemek Pytel, I am really impressed by what you did here.

0:15:58.240,0:16:03.440
I think I never heard a Marble Machine[br]being able to play so fast and so good

0:16:03.440,0:16:08.660
and I think you just absolutely[br]pull this one off.

0:16:08.660,0:16:10.800
Thomas: - Hi Hannes and Martin.

0:16:10.800,0:16:13.700
The little sister of the MMX:

0:16:13.700,0:16:18.720
The brain, arduino nano with power transistors and keyboard.

0:16:18.720,0:16:23.860
The mechanical control unit for the marbles [br]and the solenoids.

0:16:23.860,0:16:26.520
The marble divider...

0:16:26.520,0:16:28.080
- Cool!

0:16:31.120,0:16:32.540
Wow.

0:16:32.540,0:16:37.840
- and the glockenspiel.[br][plays short melody]

0:16:38.240,0:16:43.380
- Wow! Thomas, thank you so much for showing this, this is awesome!

0:16:43.380,0:16:48.026
The whole design of this machine,[br]Thomas, is like how I wished

0:16:48.026,0:16:50.639
I had designed my machine[br]if I designed it

0:16:50.639,0:16:52.788
completely in CAD from the beginning.

0:16:52.788,0:16:57.040
Everything looks so clean and things just working...

0:16:57.040,0:16:58.800
Wow Thomas, that was really impressive

0:16:58.800,0:17:02.700
and I just searched for Exergia and I[br]found his youtube channel

0:17:02.700,0:17:07.136
and Thomas has like[br]invented a candle car kit, thermal generator...

0:17:07.136,0:17:10.079
There is so much cool stuff. Kurbel Generator...

0:17:10.080,0:17:13.980
So this candle car looks amazing,

0:17:13.980,0:17:16.761
like a car that [br]burns on a candle, I guess,

0:17:16.761,0:17:18.760
so check out Exergia's youtube channel.

0:17:18.760,0:17:22.140
Awesome Thomas, thank you so much for sending it in.

0:17:22.140,0:17:26.240
[speaking Spanish][br]"Por todos las chicas y chicos de España."

0:17:26.240,0:17:31.120
"Tenemos un youtube channel, [br]se llama Wintergatan ESP."

0:17:31.120,0:17:36.920
"Estudio guitarra flamenca, en el sur de España en la ciudad de Sevilla."

0:17:38.480,0:17:43.400
"Hablar un poquito, comprendire nada."

0:17:43.700,0:17:50.520
"Pero mon amigo Carlos ..."[br]He is a very nice guy and he is translating

0:17:50.720,0:17:56.300
all our Wintergatan videos into Spanish [br]on the Wintergatan ESP youtube channel.

0:17:56.300,0:17:59.020
If you know anyone from Latin America or Spain

0:17:59.020,0:18:00.880
who you think[br]might be interested in becoming part of

0:18:00.880,0:18:04.338
the Wintergatan community,[br]please tell them about

0:18:04.340,0:18:07.360
the Wintergatan ESP youtube channel

0:18:07.360,0:18:09.740
because the algorithm is[br]not really finding it yet.

0:18:09.740,0:18:12.020
So if you could tell them about that, it would be

0:18:12.020,0:18:15.780
a great help for the Wintergatan youtube channel.

0:18:15.780,0:18:20.140
And I actually did study flamenco guitar in Sevilla in the south of Spain.

0:18:20.140,0:18:26.080
It was... I was a disaster as flamenco student[br]but I picked up a little bit of Spanish,

0:18:26.080,0:18:28.126
but Carlos is doing it really well.

0:18:28.126,0:18:30.780
Thanks, to Carlos Montoro from Anjuda Guitars,

0:18:30.780,0:18:35.240
for making all the translations for the Wintergatan ESP[br]Spanish youtube channel.

0:18:35.246,0:18:35.919
Check it out!

0:18:35.919,0:18:40.400

0:18:42.327,0:18:44.020

And you know, we see you next week

0:18:46.844,0:18:49.840
on the next Wintergatan Wednesdays.

0:18:49.840,0:18:54.000
Take care everybody.[br]Bye!

0:18:54.440,0:18:57.440
- Boom!
