Why 99% is NOT Enough - Marble Machine X Accuracy test 

A surprise tool that will help us later

All those little tricks he's picked up through working with everyone on the discord and all the trial and error he's done himself... It's so amazing to watch him go through such an amazing process.

Every time

@@harborwolf22 the process of reiterating content at a minimum of 10k dollars a month you mean :-)

@@harborwolf22 Well said.

Hahahahaha, yeah can I have more "stress" please? It's very relaxing.

And a little stressful. As soon as the large queue was through I did a big exhale lol

But just before the queue reached the fish stairs in the back, Mr Marble saw the upcomming problem and helped speed up the marbles with a little push... Is that allowed, when stress testing? I felt kinda cheated.

Makes me want to play with some shiny beautiful metallic marbles

It looks like a way to absorb energy from the marbles. It's probably done on purpose

WOW, look how efficiently it produces nothing of value - something I have dedicated my life to.

I think he would get far more part longevity if the dividers and races were made of hardened steel.

@@flyman451 But this is a VERY good way to prototype, cheaply, before the increased cost of CNC'ing metal works.

Yeah, only thing I’m worried about is if the rockers could be made quieter, and how much they’ll wear. Your stream last night was great btw.

Hi desinc I’m glad you liked my gamer village monument thing lol

DeSinc, you're everywhere

Oh hey it's Asmongloid again. You have great taste

Solid state? The original was transistor-based?

Imagine if the creation process of the 3 violin machine or one of the others was documented.

That's why I'm confident it will end up in a museum. It's not only a feat of musicianship and engineering. It's a feat of the information era and crowdsourcing - the first of its kind.

@@coder0xff I find it to be the most fascinating aspect of this whole project. What was originally a singular effort by Martin has evolved into an entire online community pouring out their collective resources and expertise to help one man design one of the most intricate instruments ever made.

This machine is museum worthy

Weird that 5 years of this, and still people think the original machine was a working thing and not just a prop for a music video.

Yes, but perfection can be the enemy of good enough. When is the last time you heard the marble machine make music? He's obsessing over 100%, but what was the objective? Sometimes you can get so lost in the minutae of perfection, you lose sight of the beauty you were trying to create in the first place.

anyone can make a bridge that stands up an engineer can make a bridge that barely stands up

@@pawpawstew i so want to see this beatifull machine play something, but 99% isnt enough for martin so he quits, but for probably most of us 99% is far better then expected, if he loses 0.5% marbles it doesnt really matter to the listener, he only has to have a hand full on him so every time they get low he can refill them. we all loved the first one, yet we can understand that its nowhere near good enough to go on tour, yet this one got in my opinion close enough since in normal music you also have a chance to brake a string, bow, or clog a pipe. so noone expected 100%.

@@patdbus really sad we are never going to see or hear this in action 😢

Level 4 of that marble divider could be in the shape of the divider channels, so they won't hit the opposite wall while being divided, instead make a "V" shaped wall, so they travel smoother :)

Best process, is no process ;)

False dichotomy! :)

Those loose bolts are like sliding marks made by SN15 landing legs; all most inconsequential but will be fixed for next time.

Sometimes things need to be loose for reliability. It might look dodgy, but sometimes it makes that last bit of difference between a reliable machine and a paperweight

@@233kosta Yeah I think they are loose on purpose, because the marbles might bounce off the stopper in undesirable ways if it was stiff.

@@wombat4191 Bit of damping never hurt anyone, but this isn't an ideal solution - it'll wear and generate dust. Better off with a proper soft-ish damping material instead.

@@wombat4191 with the washers and difference in height between the two bolts, I think it was just an assembly oversight.

For real

Good practices are recommendations, you don't have to follow them, even if you yourself said it xd

If you look at each part he has made, he has tried to build everything as simple as possible. You never know if something might fail. Easier to fabricate a new part if the design isn't overly complicated.

You do understand that most instruments, even though they seem simple, are way more complicated and delicate than a machine he built out of plywood in his garage? Like, his example was perfect, using a midi keyboard, if you think about it, a keyboard is overcomplicated as f lol

2:22 Nope, it still was dividing equally lol it just appeared so as 1 and 2 *STAYED* full

Indeed. It was also very sensitive to its internal geometry so any machining errors will come out as a channel preference, likewise with erosion over its lifespan (which are both very real considerations in a passive sorting mechanism like this that relies on principles of balanced gravity and friction!)

it also be sensitive de vibrations

I concur with all of the above

I thought this too. The old divider would still work well but it would need to be perfectly horizontal in the 'exit plane' and only slope from the single entry point towards the 4 exits to ensure all forces on the marbles were more equal than previously. I still think that the V2 version of the divider is still the strongest and viable option as there are less pieces so less points of failure. An option to manually add marbles would fix any flaws if needed but I suspect a slope on a single angle would fix it's flaws and remove marble preference to the lower lanes.

I was thinking "he's building in a mole and it's going to pop up whenever the floor isn't perfectly level." Glad to see he decided to go to a mechanical splitter.

the most german statement ever

Why is the divider tilted? Isn't gravity causing this problem?

@@mviz2299 yes the original design relied in oerfect6 balance, but it would always favour one direction, due to the corner and momentum.. or wavelength issues

How to overengineer it ? Maybe a gate with computer control ??

As Elon Musk says it's less impressive of what an engineer can make and more impressive of what an engineer can delete.

It really reminds me of the time spent on factorio, but way more satisfying to watch.

Nothing? Keep watching more of his vids and you'll realise that it's far from it!

@@themastermoo dont tell me

That's kind of like saying fitness is useless because your just lifting weights to put them back in the same place again.

I think he has lost his marbles

Agreed, its essentially a system with binary memory instead of analog memory (the exact position of the marbles) which determines the output of the flow divider, and since each divider only has two states its easy to troubleshoot and implement now.

Thats what i thought. A manual logic gate haha

It also doesn't need to be as level either, since there isn't a way for marbles to favour a path on any incline; the gates guide things to exactly where they need to go.

Now I'm just waiting to see a turing complete marble machine

@@pow3rstrik3 We will be doomed! Doomed I tell you!

@Homunculus Yes he is

2:22 Nope, it still was dividing equally lol it just appeared so as 1 and 2 *STAYED* full

@@firstnamelastname8790 i think it mightve actually been slightly off bit even if it were perfect, there was still the issue of clogging resulting in catastrophic failure in only 13 minutes, barely enough time for about 2 medium sized songs or 1 longer song. The new design not only matched the incoming flow but was able to process marbles fast enough that it'll likely never clog again there.

It's like watching the musical equivalent of Elon Musk. Due to necessity, suddenly an engineer is born. This isn't the end, this isn't even the beginning of the end, this is the end of the beginning.

me and many more kept nagging on Martin to watch more "clock mechanics" videos.. show's that he rly get's more in to mechanical engineering now than music x'D

If you haven't already you gotta watch one of his videos where he is actually using it to make music.

How does that happen?

@@merlijnbakker8797 shutter speed of the camera is matching the movement speed of the machine. Look up "Helicopter rotor matches shutter speed" for a really good look at the effect

@@merlijnbakker8797 Manual fast forward (think old movie projectors) works by increasing the rate at which frames (still photos that comprise a movie picture) move through the observer’s view. In the digital world, data compression is only so good, so it starts to cut out frames to create the illusion of increased speed. If you cut out the right frames in the right order, you can create all sorts of wacky visuals. Think of the fish stair as a series of movements on camera. At the bottom of the cycle, the fish stair picks up a marble [an action we will represent with this circle icon ⏺]. Then it lifts up the marble to the next step [this one will be represented by an upward arrow 🔼]. After the fish stair reaches the top, it deposits the marble in the next step [to be represented by this square ⏹], and then goes back down [the obvious choice here is the down arrow 🔽] to begin all over again. In symbolic form the whole process looks like this: ⏺🔼⏹🔽 If we string multiple cycles together, we can get long repetitive chains: ⏺🔼⏹🔽⏺🔼⏹🔽⏺🔼⏹🔽⏺🔼⏹🔽⏺🔼⏹🔽 (Five full cycles) ⏺🔼⏹🔽 ⏺🔼⏹🔽 ⏺🔼⏹🔽 ⏺🔼⏹🔽 ⏺🔼⏹🔽 Now, let’s say that we’re filming the fish stair with a camera that takes one frame every time that we would use a new symbol. If we were playing that video back at regular speed, we would just see the same thing we observed in real life: ⏺🔼⏹🔽⏺🔼⏹🔽⏺🔼⏹🔽⏺🔼⏹🔽⏺🔼⏹🔽 (Still five full cycles) ⏺🔼⏹🔽 ⏺🔼⏹🔽 ⏺🔼⏹🔽 ⏺🔼⏹🔽 ⏺🔼⏹🔽 If we wanted to fast forward this video, we have to start cutting/compressing frames. Let’s say that we want to run this again at x2 speed. That means cutting out every other frame so that we can get the same length of video into half the time. With our pretend camera it would look like this: ⏺⏹⏺⏹⏺⏹⏺⏹⏺⏹ (Two frames from each cycle remain, two have been cut [✂️]) ⏺✂️⏹✂️ ⏺✂️⏹✂️ ⏺✂️⏹✂️ ⏺✂️⏹✂️ ⏺✂️⏹✂️ See how we lost all of the frames showing up and down motion of the fish stair? In your brain, that would make it look like the machine was running twice as fast (or like really bad stop-motion animation) because your brain fills in the gaps between the frames with what it imagines is happening, just like any video. But, things start to get trippy if we want to run our special video at x5 speed specifically. We would have to cut out four of every five frames, which leaves us with the following: ⏺🔼⏹🔽 (The reason it looks like this is because we are getting a different frame from each cycle and stitching them together in the right order) ⏺✂️✂️✂️ ✂️🔼✂️✂️ ✂️✂️⏹✂️ ✂️✂️✂️🔽 ✂️✂️✂️✂️ In this particular instance, even though the rest of the objects in the frame would appear to be moving five times faster than usual, the fish stair would appear to be operating at normal speed. This is what was happening with the real fish stair at x32 speed in Martin’s video. The playback was lining up just right so that the selected frames were showing the fish stair as though normal, while everything else was still being shown at great speed. Sorry for the long-winded explanation: I hope that it helps!

@@LOVEMUFFIN_official Wow, thats a clear explanation! I get it now, crazy that even the rolling marbles seem to go at their normal speed, as if they are actually unique marbles. I played it on 0.25 speed (the x32 speed part) and saw some marbles jumping back and forwards through the pmma pipe, which double proved me that Martin didnt edited the video to see if we would notice it which i thought was the case initially.

Yeah. It's Physics and logic/statistics.

Those are ball bearings

@@mchinZR lol

Too bad he's seek for perfection lead to the project's death.

@@Speed001 I think he's taken the statistics out of it.

I thought its ugly too, but then I named it as a frog-desing. Then became nice Wilsons friend.

"Pain is temporary..."

😂

I could be imagining things, but to me it sounded more quiet than the marbles moving along the top and possibly even in the pipes.

Cool. I used this to make a rain counter once. Instead of measuring the amount of rain, I needed only to count the number of flips and flops

"what instrument do you play?" *SHOWS THE WINTERGATAN INSTRUMENT WALL*

Don't forget the frisbee ;-)

Ball bearings

I feel like Martin also plays the washers... Definitely in the uttermost beautiful way he pronounces it.

You mean Resilient

make it idiot proof. problem is ...theres always a better idiot

The KISS principle.

Martin has yet to adhere to this standard though, the problem isn't the subassemblies but the design of the overall machine, Martin tries to apply engineering principles but he let's the musician in himself take over, both in subassemblies and in overall design, I'd argue more in overall design since it was made some time ago and he was less experienced engineering wise at that time, it still creeps up a lot though, a majority of which I would argue is because of that old overall design, as a programmer, if I get to a point in a project where I continously rewrite some part of the code because of underlying architecture I start wagering to rewrite that underlying architecture, it may be more work now, but it will save much more work in the future, and these rewrites tend to happen multiple times before an efficient and user friendly architecture is found, in the end, everything is a prototype

@@msx80 I mean no actually. Why I used the word reliable is because I want to encapsulate the idea of a very low failure rate as a whole. While making a thing resilient is important part of that, you also have to make it consistent, durable and easily repaired

First I thought you are talking about the overflow at 3:10.

I estimate there is (front to back) 61, 60, 59, and 59 marbles in the tubes to the pinch. So yeah that is a decent amount of weight.

In that context this would just be a round-robin LB, right?

You've saved me the time of making the very same comment.

@@onetdev Thank you and you're welcome! I wanted to say so much more. But, less is more.

..passing so fast you can't see it move.

Dust in the wind....all we are is dust in the wind

I get u, but even at 32x speed, it takes 2 seconds for a minute to pass. ~2 minutes for 1 hour to pass. So time really wasn't moving that fast.

Sometimes i stare at myself on the mirror and think about my existence and why did this world and everything on and around it appear and who made everything?

@@dirtblock1383 mind-numbing questions that can either break you or deliver you to freedom.

just subscribed to you, your channel looks interesting :)

But it does introduce some noise, but you could change where it flows into the flop, maybe another bit of pipe or slight angle change.

The best divide by 4 is no divide by 4. There are simpler more reliable ways to recycle marbles but Martin keeps holding onto risky designs which he already saw fail in the original marble machine, like this...

@@tommj4365 I don't understand the need for a divide by 4, one at a time. Why not divide by 4, always grabbing four at a time?

​@@brockstanford7608basically Martin wanted the cool visual effect of a fish stair pumping in sync with the music, and 4 at a time provided the ideal throughput. your idea (if I understand correctly) of just grabbing 4 at the bottom of the fishstair was actually suggested and prototyped, but it seemed pretty quickly dismissed for some reason.

I don't belive they would. If you start it with all the rockers the same way (toward the camera). Starting from the camera back would be slots 1,2,3,4. The marbles go up. The 1st marble would go into slot 1, 2nd to slot 3, 3rd into slot 2 and 4th into slot 4, repeat. Since the 4th slot marble loads 1st each time it would go to slot 1 changing the color. If I figured it out right, slot 1 and 4 would alternate between each other while slot 2 and 3 would stay the same.

@@JasonDeath It would still be neat to see... probably a great visual effect in the long term, but given the weight (and random size in glass) difference between glass and steel marbles, it would be hard to do. You couldn't just paint the marbles either... they would have to be different colors of steel, which would probably have to be specially manufactured.

I love the idea of the colored marble experiment. However, I think that depending on what music was being played, the marbles would go to different paths to hit different notes, etc, and would then have to travel back to the supply tube via different routes, and therefore would mess up the placement of each marble. Cool thought though and I'd try it anyway. 🙂

accuracy when not playing, but if they jump "out" back to the system in different speed, then all stuff will change

This this! I think having a count that's from the bottom, as that will show how many marbles that are used to make the music.

definitely!!

@@raphaelho3551 failing marbles (not that we want to see some) will get their own counter, labeled "body count"?

Great idea. I've watched musicians play and wondered just how many notes they just played. Now we'd know!

Where would the counter go?

That means the elevation movement itself synchronized with the 32x video framerate, creating a movement illusion. I'm pretty sure there's a technical term for that, but i have no idea.

I see that, amazing woodworking and design.
