RUclips made this video available in 4K finally! There have been some issues with youtube not displaying our recent videos in 4K but if you have a 4K screen you can now take a look at the clean floor in hi res.
That's what I was thinking too... it's a lot like balancing car wheels, and with flywheels in particular, mass balancing matters a whole lot more. I've once seen in person what happens when an unbalanced mass of only about 5kg is spinning up to a targeted 3000rpm. The outcome was not pretty. No injuries, but frightening carnage to machinery.
Dear RUclips: please don't recommend super awesome and fascinating videos in the middle of the night, when I'm just searching for something to lull me back to sleep.
I admire this man and his attitude so much. I hope he never forgets he’s doing so much more than building a machine, he’s motivating millions of people.
martin: bad news and good news! me: oh dear martin: bad news is the flywheel is unbalanced me: oh dear martin: good news is *pulls out unholy angle grinder rig forsaken by god* me: OH DEAR
Martin, the purpose of the squished cable in the angle grinder is strain relief. My guess is the issue was in the plug, but I recommend putting the strain relief back in because if you don't the cable might pull out of the internal switch, short, and in the worst case start a fire.
If it's to squished too hard and it gets too hot, the wires melt together and short. However, could also just be that this will happen with any grinder (or any machine) that gets used beyond its duty cycle and load.
@@cjansson It can't be "squished to hard". The inbuilt plastic crimp is sized to compress the insulation sufficiently to prevent cord pull out under normal wear and tear but not compromise the insulative properties of the jacketing.
If it shorts out, it will pop the breaker. Just one strand of copper is enough to start a low impedance arc which will trip the breaker in tenths of seconds. A short circuit does not cause fire, unless the electrical installation of the building is bad (or if you reclose a breaker with the fault still existing - that can pit contacts and eventually weld them together...) Intermittently arcing contacts to the load can cause fires, but in this case you'd immediately notice if the grinder is not running smoothly and most of the times the plastics are flame retardent. I agree there should be strain relief, otherwise it'll just work itself out of there quickly.
@@williamcchinworth7367 I'm pretty fucking sure the inbuilt plastic crimp was never "sized" for anything, it has just been thrown in there to "looks fine" standards. Which may easily include "it's not fine at all you idiot" situations.
@@Talaxianer ah okay, just curious ^^ as he is originally from Sweden it's no big wonder. I'm from Germany, we also write "Idee" but pronounce it completely different.
Can we stop for a moment to just appreciate how wicked cool that music is? I was listening to the snare drops trying to understand the rhythm of the two 16th note beats in succession and was delightfully surprised to see how it all worked in the song. Martin, you're a genius!
As an engineer who has worked many years in “Quality and Reliability”, you cannot put the six in the FAILED column. They did not fail for what you were testing. They are a “new failure mechanism”. Analysis shows a design defect in the feed mechanism for not limiting the flow for such a small flow of marbles to the main mechanism.
I think he counted the 6 in the count because he's not just counting marbles that escaped the machine where the marbles were let loose to hit the instruments. This was an overall whole-machine stress test (except for the unplayed portions) and those 6 lost marbles showed there was a specific set of conditions that need to be addressed.
As a QE. Martin’s Definition of a defect was a marble on the floor. So it counts. The cause of the failure is different. If writing a FMEA it would have the same effect but different cause.
@@calvinthedestroyer actually it is a feature when you think of it: it's a damage free fail-safe which allow for the continuation of the feeding loop, at the expense of losing x marbles from it. I really would have put a tray and let it stay were it for me: fixing it would probably make it worse if something happened
especially when you think that out of ballence does not mean i has to be straight on the otuside. the inner parts need to be balanced too. how true it spins has less to do with shaking than mass distribution, so yeah, he is making it harder on himself. But it's still fun to watch
This vid really shows how much work went into this music machine. Its almost overwhelming to see all the little tweaks and adjustments needed to make this brilliant piece of art work. Its crazy.
10 year after: we have some temperature vibrations, so we freeze mmx to absolute zero) 1 fail of 10000000000 marbles, next vieo we stabilized gravitation and playing in vacuum
Hi Martin, some thoughts from me: -I think the missing thunnel hit occurs when you have a fast double bounce on the snare, one marble is landing on the snare when the drum skin is moving up from the previous marble. It is like beein two people jumping on a trampoline, with a perfect pace you will get an extra high bounce caused by the other guy. You should therefor test the dropping with all different intervals you can set on the programming wheel. Maybe this phenomen is even worse on the vibrophone?? -A belt tensioner shouls always sit on the slack side of the belt, look at a mountain bike chain as a example. You will loose efficiency by having one on the active side and therefore add drag in your system. And if you weld it onto your frame, make sure the tensioner is ajustable with a sliding slot!! Another cool way to solve a tensioner is a "ring tensioner" google it, would look realy cool on your machine. -I see a big risk with the gates. There is a long leverarm down to the gate from the actuator. Even if you make this gate work fine, you will have problem when you start install the other gates bechause you dont have the same height between the actuator and the gates. Therefore the leverarm will have different length and that will affect the traveling lenght of the gate opener, also affect the pull out force on the gate opener. To solve this you need to redesign the gate. Instead of having a lever arm you should having a vertical pull from the actuator and a link in the gate to pull it out. That would make equal force and traveling lenght independent of the height between the actuator and the gate. Thanks for you amazing work so far an to share it to us! /Johannes
From Johannes to Johannes, so much this! Especially the last point. My mechanical engineering heart hurts more and more because I feel like martin it slowly but surely digging a whole he can't get out of. I sincierly hope he can fix the flaws and get over the whole reliability thing.
The "bouncing problem" you describe can maybe also be adressed by tuning the snare to a different note, so the vibrations of the drumskin have a lower probability of positively interfering with double marble drops
sherlock_norris I concur totally, as a drummer I know the different actions of bounce on different tensions on the drum head, my first thought on the last video was, the double bounce on the snare is causing the miss, this is the only variable change from the video where there was no misses
@@clonkex Yeah that's true. But so far on this journey we have been with Martin throughout all his wins and fails. So it would be really good to be with him as he achieves one of the biggest milestones ever on the MMX
I love how this channel began as a music channel with cool instruments, then turned to an engineering channel with a musical sidedish of music and is now slowly combining both
It is weird to see the cell linking feature to not be used with maths like this. It is so much easier and reliable to just construct the formula once and then copy it to the rest of the rows instead of risking inputting incorrect variables.
Martin, it's a good thing those marbles fell off at the end. A perfect test teaches you nothing. This test identified a failure mode. Loved the video as ever!
Let's appreciate for a moment the character it takes to publish days* of personal failure and a moment of success with that flywheel. He could have skipped that and we would not have known, but he shared it.
You are like the most inspirational engineer/musician. I love that you don't stop at easy, but you design for maximum functionality as well as aesthetic. As a wannabe musician/mathematician/computer scientist, I love watching your videos and they make me want to apply my knowledge the way you do. Btw, if you had stickers in your merch store, I'd buy some.
Everything about this. The design, trial, error, solutions. It's absolutely beautiful and I am so happy that you are able to share this with us. Thank you so much!
Completely harmless? One day a marble will get stuck between moving mechanisms and jam up the machine. The only safety feature in this case is the fly wheel disengage mechanism which will probably put to much force on the jammed mechanism and locally destroy the machine. Failing marbles are always a risk for this machine as long as there are almost no safety features in place. Martin is going to find this out someday. So sadly enough failing marbles are not so harmless in my opinion :(
@@FrankyieFrank I think in actually practical usage he would be able to look for the errors and stop them before they happen. Well, that's what I think.
@@FrankyieFrank Yeah but the thing is that the cause of the fails is not a part that is going to snap of a desing flaw that needs some plastic surgery. It's just a interchangeable part (and too many marbles in my oppinion) that caused the overflow to, you know, overflow. If one of those stray marbles would cause something to break would absolutely suck, but compared to the other things he had to do this far, I would't even call this a fix. Just a bit of fine tuning.
@@FrankyieFrank Sure, I agree that it could cause a jam somewhere else, and I also agree that the machine needs more failsafes. But I still think the test was a roaring sucuess.
@@FrankyieFrank I think what was meant is that only six marbles failed due to the test setup: If all instruments are playing, the line of marbles will never back up far enough to flood the stair elevator.
I hovered round the unsubscribe button when I saw him bring up the calculator to do calculations for the spreadsheet!!! The data cells are just beside the percentage cell!!!
@@heitman78 I mean I'm not gonna pretend I'm anywhere near an excel expert, but this is simple formulas. Literally just type = in front of the formulas you already have and it'll do it for you, martin!
Martin takes out the angle grinder to balance the Flywheel: Me (working for a reasonable time in a balancing company) - thats not how balancing works. I suggest using magnets. 2mins later: Martin uses magnets.
@@dmdeemer Same here. I just noticed my tires getting out of balance yesterday. Today I see this and I see the grinder and cringe. Then he fixes it proper and I sigh in relief.
Exactly. It didnt matter if the flywheel was true, it mattered that it was balanced. He was equating true with balanced. At the machine shop they true flywheels so the clutch mates, and then balance them so they rotate smooth and dont shudder.
We need a “Look At That CLEAN FLOOR” shirt. Also, be wary, Martin. It feels, right now, like everything is perfect; but I think there’s a flaw in your logic. You’re testing for stability in an unfinished product. There’s going to be a lot more mass, and shifting of mass, one *all droppers are installed.* Testing for stability before you have initial stability measured is going to make you sad later on, when additional active and installed gates change the dynamic of the whole machine. I recommend focusing on that aspect before running any extreme amount of marbles; especially because it’ll make that test a lot faster and, most importantly: realistic.
I also worry about the world tour. A lot of stages will be portable stages, resting on soil or something. Won't there be lots of vibration in the stage floor with half a dozen people moving around, moving instruments around, etc.? How will he eliminate that?
@@thanbo The vibration from the audience might be the one need to be careful about. For the vibration from the technician moving around on stage and other musician moving around on stage, there is a simple solution. As the MMX is centerpiece, using a dedicated stage for it is good enough. You know, just like DeadMau5 concert where just for him they made a dedicated stage. MMX don't need that large of dedicated stage, so I think its possible to make a "portable-ish" dedicated stage for it on world tour. For vibration from the audience, yeah it needs more expertise to deal with it.
You know, there is always some setup time before a show ... Installation, tuning, tests, and so on ... I'm sure that, with all the works done now, it will cut down on setup time and will be manageable in the end !
Also, having such a high reliability in perfect conditions gives some headroom for errors when the setup is suboptimal on tour. As many have pointed out it's not the end of the world if some marbles escapes during a concert. If 1/10'000 escapes in the studio it might be 10/10'000 on stage with limited setup time. But it makes sense to get it as good as possible now.
Yeah, setting the machine up to be exactly the same each time might be quite the task. I can see different venues having different temperatures and humidity, the machine may also need to acclimatise. I don't know how this would affect the machine working but I'd probably want to do some long running tests in different environmental conditions.
@@isakefternamn it isn't the fact that the machine has high reliability in studio conditions that worries me...it is the fact that it needs high reliability to work properly. As we have seen already, minuscule deviations from "perfect" cause a cascade of issues. It is this very narrow "operational window" that gives me anxiety.
Its cool how not only is this refining the machine to be smoother quieter and more accurate, but its also serving as a sort of break-in period for the machine as well.
I love how this whole series seems to be a guy saying "There was an easier way to do it... but that wasn't nearly as fun." People like this need all the support we can give.
I was the opposite! I thought, he won't burn that machine up, he'll just grind the wheel down to nothing!!!! I was actually frightened, then even more so when he says 3 days.....AHHHHHHH!!!! Then the magnets come out to balance things, oh thank goodness!!!
At some point, the marbles that miss are going to be caused by a slight breeze coming through the window, and Martin will engineer something to counteract it
Quite simple, actually. Just contain the MMX within a vacuum so there's no air to make a breeze! Thinking about it, that might also solve any humidity or temperature change problems. Huh
@@alvardo3000 That actually wouldn’t be a problem for most of the MMX’s instruments. The bass has pickups, so it doesn’t need air, and Martin mentioned someone’s suggestion to use magnets with the vibraphone bars which essentially gives them pickups as well. The kick uses a contact mic, so again, no air needed. The main issues would be the snare, hi-hat and cymbal, because those don’t use pickups or contact mics. You can still give them all contact mics, but they likely won’t sound the same or as good. So if you didn’t care about getting a perfect sound, a vacuum wouldn’t be an issue
But... making a vaccum that big is practically impossible, especially on the go in the world tour. He also would need to stand inside of thr vaccum to operate the machine, killing him due to lack of oxygen.
Martin: builds worlds most impressive mechanical musical instrument Also Martin: uses a calculator instead of formulas to fill out his Excel spreadsheet Martin I will gladly give you a 30 min tutorial on how to do this properly
💥💥IMPORTANT SNARE INFO💥💥(coming from concert band percussionist) - I’m not sure if you’re aware of this already but the snare is similar to the vibraphone in the sense that you almost NEVER hit a snare dead center as it gives you a much more dead/less crisp sound and is know as.....THE DEAD SPOT (optimal striking position is usually a few inches from the center). I would be extremely intrigued to see you do some basic tests regarding drop placement on the snare as I think this could greatly improve your sound quality in performances but especially recordings. I hate to be that guy but I feel that this is important since snare is in nearly everything. To anyone who reads, please like and reply to this so he can take this into consideration!! Much love Martin❤️
@@CupcakePump I'm also a percussionist and can confirm it's definitely true. It's not as big a deal with a snare drum as it is with a tympani (those you _never_ hit 'em dead center because it won't resonate at all), but the sweet spot is almost always about halfway between the center and the rim. Compare that to mallet instruments where you DO want to strike near the center because that's how their resonance works.
Something that may help with those vibrations. To reduce "ressonance", try cutting a couple of holes at the top of the square tubing and filling the frame with sand. Sand will add mass to the supporting frame and absorb part of the vibrations. I recall ToT also did that on his CNC building series.
@@litrick5471 I've known so-called-pros who grab a hammer and start hitting before thinking to fix any-and-every-thing... Martin tends to grab the angle-grinder first and can almost fix anything with it.
Martin: Uses google sheets to record test numbers like a reasonable human would Also Martin: ALT TABS TO A CALCULATOR TO DO THE COMPUTATION AND FILLS THEM IN Why are you doing this to us Martin? T_T
Music is art, is math, is engineering, is art , is music...breath, relax, laugh, cry, shout, learn. What a marvelous journey/exploration/experiment. It gives me hope for humanity that we can be this close to the Creator and kissed by humility enough to see difference. Shalom!
After seeing this I now envision the angle grinder being part of the world tour. It goes like this: music reaches a crescendo, Martin throws a lever up top, angle grinder sends sparks across the stage while a large LED display behind him flashes "Pain is temporary."
I've said this before, but he absolutely has to write a pair of songs for the MMX of which one is called "Pain is temporary" and the other one "Glory is forever"
@@IbakonFerba With build clips of the MMX playing on the screen behind. Massive effort to develop, install and perfect, only to be cut off for the next, better, version.
@@riddixdan5572 yup, in Cars they use small lead weights to Balance the wheels. whenever you get a new tyre, the weights have to bei adjusted so the wheel is balanced
Your runners need to be spring-loaded or you'll run into trouble. Over time with the runners stressing the belt combined with temperature swings the belt is going to stretch, this is what lead to the problem you have now that made you add runners, by making them static/not adjustable you're just kicking the can down the road, you need to plan for this. In your workshop things might be okay for months before you notice a problem but on the road? you'll be going from warm venues to not temperature controlled vans over and over, if the van is generally colder than the stage you'll have extra stress on the belt when you're not using it and when you come to use it the belt will be loose again. If the van is generally hotter than the stage then when you're on stage you'll have that extra stress while also being under the load of playing. At some point it's going to stretch and it may cause you to drop from your 99.99999% goal
this has been one of my big frustrations throughout the entirety of the series really. He'll have a good idea, but then do a half job implementing it. Which then causes problems. Which he'll solve with another clever idea, but once again with a half job of implementing. I get that he has also been learning this entire time, but you'd think with a team of engineers backing him that stuff like this would get caught and corrected.
Belts are probably cheap and readily available enough to just be replaced on the road. Not to mention the main portion of the vibration, which was causing the drops, came from the flywheel being unbalanced. So the belt thing is probably more cosmetic than necessary.
And he should only have an idler on the slack side of the belt. He gets half-way there with these designs, but just doesn't have the engineering experience and exposure to fix it once, so he ends up in integration hell.
Honestly, even though 6 marbles fell, it actually wasn't 6 failures. The reason being that it was loading multiple marbles and they all fell at the same time as part of the same overflow failure. So reliability is actually higher
There's also the fact that the failure happened obviously outside of normal operation ie. several hours of uninterupted use of a single instrament. If it were me, I would note it down as a possible point of failure while moving forward with the rest of the instuments. It's possible that using more gates at once would prevent this from happening again, or even just the breaks between songs. The cause of the failure may even just be that MMX had more marbles in circulation than it could handle when only playing the snare.
@@Sorestlor that is why he should do a calculation of minimum number of marbles needed for the machine to play smoothly. As well as calculate maximum number of marbles that the machine can support.
While the probability is low. This was just one of many future gates each with the same potential failure point. So the real failure probability is actually quite high, almost to the point of being certain over the course of an entire concert. In addition, the marble loss is a minor symptom compared to the potential failure of several instruments downstream of the blockage from receiving any marbles at all.
You are using your brain and life in the exactly the way you where ment to. FREE. I love to hear you talk, the freedom in your voice is remarkable. We all have stressful lives your no exemption. But your contribution to our world will live on forever. You are so appreciated, it makes my heart joyfully for you. Be well and never stop
I think Martin was lucky with this test. If he had stopped 5 minutes sooner, he wouldn't have found the fault. It would come up eventually and possibly ruined the next test.
The test was a success man, it did exactly what it was supposed to do, find a flaw, and thank god it found the flaw right at the end of the test and you didn't have to run another one.
I feel like martin needs a crash course in statistics. Also, the simultaneous use of spreadsheets to display information, while using a pocket calculator to calculate things makes me crazy.
My head was exploding on why he didn't use excel to do the formulas. Martin if you're reading this and need help with Excel/Google Sheets, hit me up! I'll be glad to help out :)
Reminds me of my mom who does the exact same. A spreadsheet is just a handy table to out numbers in, all calculations are done on her physical calculator. No adjustability whatsoever. W I C K E D
Yes and no. Assuming the snare channels were the only ones with improper marble heights in the marble divider, then you likely wouldn't see this issue occur, however it still delays marbles from getting to the hi-hat and bass channels, which is an issue this test doesn't show. But if other channels also had improper marble heights, the issue would be compounded as there would be buildups causing and adding to more buildups, so the issue would actually happen *more* frequently
Also, this is one of the most complex channels because of the longer parts and drops, so what he learns here will easily apply to rebuilding the other channels.
Not gonna lie, when the bass and guitar came in on the play-along, I literally teared up. It’s just so awesome to see music involving the marble machine actually coming together, after all this time. Plus Martin’s beautiful musical mind generating tear-jerking chord progressions. I can’t wait to see the million 0 drops video. I also can’t wait to see it live on the world tour.
This is the most complex and demanding DIY one man project I've ever seen online, your dedication is outstanding, people like you are just so precious for all human race, never stop sharing your genius!!!!
I hate, really hate myself for this comment. When you said that the flywheel was unbalanced, my only thought was! Take it to a tyre fitting centre and get them to balance it or mark it. Sorry.
@@sven31415 Even owning a bicycle you might get the odd out of balance wheel and learn the simple fact that geometry alone does not balance a spinning wheel.
3 года назад+11
Imagine the guy at the tire fitting center angle grinding your wheel to balance it
Just remember this as well: theoretically some problems, especially those with the marble divider, should be less likely once you start using more channels!
Imho I would argue that this is actually good test case to refine for. We wouldn't want a break/slow down in the song, or if we just shut off a ton of channels for a while, to become an issue. I'm still nervous when i look at the marble divider in terms of capacity. If you ask me, the marble divider should be able to hold *all* of the marbles that could be in the entire machine while running. MM1 had massive marble divider space.
@@sunray501 I mean, it took gradual build up over FOUR hours of constant playtime for the failure to occur, and that was in the edge case of only one channel being played. With more channels seeing use over, let's say, a 10 minute song (probably generous) I don't think it even counts as an issue.
May be an issue if too many marbles are in the machine. Take a few out so there's no chance of that backlog. Or maybe have a reservoir somewhere other than the top of the machine
an overflow condition must be accounted for. depending on the conditions it may actually be *more* likely to happen because of the total number of marbles in the machine; a high "marble flow rate" could cause a failure to cascade much more quickly and cause new/more problems
We're all frustrated at his efforts applied to grinding the flywheel, but the dude is a genius and works way harder than I would. To say nothing about the time spent making the video.
I'm not frustrated. This guy is a musician with no formal training in building or engineering. The amount of things he has learned/ taught himself over the last 3 years is staggering. What frustrates me is the number of actual engineers shitting on him in the comments with short, self important criticisms and complaints :( There's also a lot of helpful, productive commenting, but all the positivity of the comment section circa 6 months ago seems to be gone
It's not really that big of a deal when you consider this is how your car tires are routinely balanced. Only pound on lead weights for regular rims and sticker weights for Mag rims.
I like marbles 🐢 In all seriousness, you my friend are one of the most talented individuals I have ever had the pleasure of seeing in my 35 years of life. Thanks for sharing your talents.
@@conradkai9705 It's actually the same concept behind car wheels. Basically none are perfect, which is why mechanics add balancing blocks on the inside or outside of the rims to stop them from shaking
This video came on my recommended 2 weeks ago. “Hey! That’s the marble machine guy!” Two week later, I’ve watched every single episode up to this point. Truly inspired by your commitment and also how this project has changed the way you work. You inspire everyone here to work harder in whatever we do! This is now one of my favorite channels and I hope to go to one of your concerts once the world tour happens!
Martin: "We have to balance this wheel..." Me: "Ah, no sweat - the auto mechanics do this all the time using little weights they weld on" ... 3 days later Martin: "This geometric balancing did absolutely nothing to the balancing of mass" Me: "are you freakin' serious?!" That being said - this has to be one of my absolute favorite projects and it's mindblowingly awesome to follow you through all these efforts. To some extent, it just wouldn't be so enjoyable if everything just went nice and completely according to plan. I love all the glitches, problems, terrible decisions and wrong solutions - that's basically how life works, ain't it?
I TOTALLY AGREE! Success is good, but solving problems is ....ecstatic!. Seeing all the analysis, observations, thoughts, trials and errors is wonderful . It shows that even a genius can miss things , or get too focused . And it shows a positive side of failing....i LOVE his attitude ! This is pure craftsmanship at work ....i mean ....lamenting his welds 😆... I loved that part .....thats an artist - 98% of people aren't even gonna notice the welds let alone even think of them ....and he's going " they're not pretty enough "😂....but he's right.....no matter how small ....each element counts. And it was sorta funny he did three days of grinding ......and 3 little magnets fixed it😜.....i laughed my ass off 🤣
Not going to lie, it hurt a little bit to watch him do that. If you're going to be using a spreadsheet, then take advantage of the features of the tool you're using to do all the math for you rather than doing the math by hand and potentially introducing additional error into the data by mis-transferring the values.
@@zeushi German here. In Germany, we use comma as decimal separator and the point as group separator for thousands. In Switzerland, they say "comma" but use both point or comma. They also use single quotes or spaces for thousands. In India, they use a decimal point but don't group into thousands, but thousand and then hundreds. So these are different notations: English: 123,456,789.1011 German: 123.456.789,1011 Switzerland: 123'456'789,1011 or 123 456 789.1011 India: 12,34,56,789.1011 The German format also introduced a problem for CSV files, since comma in numbers are important and not just for convenience in reading, like the commas in English number formatting. Therefore, the "German" CSV files use semicolon as separator. I think, the world should finally come together and use the metric system with English number formats.
@@NFSHeld Also, in Australia we use 123 456 789.1011, prior to 1970 it was separated by commas instead of spaces.

I personally like the mechanical noise, it's satisfying to hear such a beautiful machine run, and for me, the biggest appeal of you channel is watching all the moving parts come together to do something so great.
Well, I must say, you executed that with precision, and brilliance! In all my years I have yet to see someone as focused as you are my friend. The way you were approached with a challenge, and excepted it, with enthusiasm and vigor. Yes, you cleaned that floor perfectly! Oh, and that music thingy, that’s cool too!
That’s why it’s the best because of how simple and effective GLaDOS I hate them and I know they did the song for portal and stuff but I still hate them so much
I have been extremely lethargic most of the time for years, and outside of work I've not had consistent hobbies in forever. I'd try learning guitar.. and quit after like a week. Get a camera, barely take it anywhere. Try learning 2d art, can't convince myself to ever actually play. But recently you have inspired me to actually do something. I've been teaching myself CAD and piano, and have been keeping at it for a while, making significantly more progress on both than I have on just about any other hobby I've had in such a long time. Congrats on this milestone, and thank you for sticking to this project, for posting such great videos, and for not giving up on this beautiful masterpiece of yours.
You could have saved yourself some trouble with the fly wheel if you would have gone to a tire shop and asked how they balance wheels. The magnet (weight) solution is exactly what they do, except they are clipped or welded to the wheel.
It's so cool to see that, now that you have "completed" the MMX you can now focus on how to "tune" it. This has been so interesting, all the ways the machine can fail, and you persevering in fixing it, this is my favorite series on RUclips!
Sometimes when watching these MMX vids it's easy to get caught up in all the engineering details and forget that Martin is such a truly _marbelous_ musician.
I'm glad the patron and RUclips member counter is going back up! These last few videos have been my favorite (although I've watched all the build videos) and the fact that almost 2,000 people cancelled their membership last month was very sad to see. Keep up the good work Martin, we're still supporting you!
@@AfonsodelCB That's true, but it's possible most of those are just $1 a month, and I'm sure all the parts cost quite a lot. I wasn't really worried about Martin financially, though. My point was that it was sad how many people stopped supporting him when he changed how he worked and did his videos.
@@mduckernz You know what, that might be it. What's funny is I didn't even consider that. Maybe that means that not so many people were unhappy with Martin's changes after all.
"The more mass, the more energy it takes to move this..." This prophetic quote will come back to haunt you when the roadies go on strike because the machine is too heavy to move...
It wouldn't be hard to add mass in a way such that it can be taken off and put back on again easily. Lumps of iron (or sand boxes) that can be screwed on in specific places, for example.
RUclips made this video available in 4K finally! There have been some issues with youtube not displaying our recent videos in 4K but if you have a 4K screen you can now take a look at the clean floor in hi res.
You're so freaking COOL! LIKE OHMYGOSH I WANT TO BE AS COOL AS YOU ARE

Ah, so that's what it was. Hurray for higher bitrates! :D
Martin learned that geometrically balancing the wheel isn't the same as balancing its mass :D
That's what I was thinking too... it's a lot like balancing car wheels, and with flywheels in particular, mass balancing matters a whole lot more. I've once seen in person what happens when an unbalanced mass of only about 5kg is spinning up to a targeted 3000rpm. The outcome was not pretty. No injuries, but frightening carnage to machinery.
Don't confuse Martin with facts.
All of us who owns a lathe knows this very well.
The second he showed the angle grinder contraption, I knew this would end in tears.
it was really grinding my gears
Martin: breaks both of his angle grinders

@@henrysteinway_ Buddy, that's even worse!
Martin, the purpose of the squished cable in the angle grinder is strain relief. My guess is the issue was in the plug, but I recommend putting the strain relief back in because if you don't the cable might pull out of the internal switch, short, and in the worst case start a fire.
Omg imagine a fire destroying the mmx...
If it's to squished too hard and it gets too hot, the wires melt together and short. However, could also just be that this will happen with any grinder (or any machine) that gets used beyond its duty cycle and load.
@@cjansson It can't be "squished to hard". The inbuilt plastic crimp is sized to compress the insulation sufficiently to prevent cord pull out under normal wear and tear but not compromise the insulative properties of the jacketing.
If it shorts out, it will pop the breaker. Just one strand of copper is enough to start a low impedance arc which will trip the breaker in tenths of seconds. A short circuit does not cause fire, unless the electrical installation of the building is bad (or if you reclose a breaker with the fault still existing - that can pit contacts and eventually weld them together...)
Intermittently arcing contacts to the load can cause fires, but in this case you'd immediately notice if the grinder is not running smoothly and most of the times the plastics are flame retardent.
I agree there should be strain relief, otherwise it'll just work itself out of there quickly.
@@williamcchinworth7367 I'm pretty fucking sure the inbuilt plastic crimp was never "sized" for anything, it has just been thrown in there to "looks fine" standards. Which may easily include "it's not fine at all you idiot" situations.

Can we stop for a moment to just appreciate how wicked cool that music is? I was listening to the snare drops trying to understand the rhythm of the two 16th note beats in succession and was delightfully surprised to see how it all worked in the song. Martin, you're a genius!
I concur!
As an engineer who has worked many years in “Quality and Reliability”, you cannot put the six in the FAILED column. They did not fail for what you were testing. They are a “new failure mechanism”. Analysis shows a design defect in the feed mechanism for not limiting the flow for such a small flow of marbles to the main mechanism.
It's a FEATURE!
I think he counted the 6 in the count because he's not just counting marbles that escaped the machine where the marbles were let loose to hit the instruments. This was an overall whole-machine stress test (except for the unplayed portions) and those 6 lost marbles showed there was a specific set of conditions that need to be addressed.
As a QE. Martin’s Definition of a defect was a marble on the floor. So it counts. The cause of the failure is different.
If writing a FMEA it would have the same effect but different cause.
@@calvinthedestroyer actually it is a feature when you think of it: it's a damage free fail-safe which allow for the continuation of the feeding loop, at the expense of losing x marbles from it. I really would have put a tray and let it stay were it for me: fixing it would probably make it worse if something happened
"I'm not here to make things easy for myself" is probably the best description for this channel I've ever heard lmao

especially when you think that out of ballence does not mean i has to be straight on the otuside. the inner parts need to be balanced too. how true it spins has less to do with shaking than mass distribution, so yeah, he is making it harder on himself. But it's still fun to watch
Life isn't easy.

This vid really shows how much work went into this music machine. Its almost overwhelming to see all the little tweaks and adjustments needed to make this brilliant piece of art work. Its crazy.

We also can’t observe it because of quantum uncertainty so maybe that one marble failed or maybe it didn’t. Next we'll test 10 billion marbles
@@fmga schrodinger's marble
Hi Martin, some thoughts from me:
-I think the missing thunnel hit occurs when you have a fast double bounce on the snare, one marble is landing on the snare when the drum skin is moving up from the previous marble. It is like beein two people jumping on a trampoline, with a perfect pace you will get an extra high bounce caused by the other guy. You should therefor test the dropping with all different intervals you can set on the programming wheel. Maybe this phenomen is even worse on the vibrophone??
-A belt tensioner shouls always sit on the slack side of the belt, look at a mountain bike chain as a example. You will loose efficiency by having one on the active side and therefore add drag in your system. And if you weld it onto your frame, make sure the tensioner is ajustable with a sliding slot!! Another cool way to solve a tensioner is a "ring tensioner" google it, would look realy cool on your machine.
-I see a big risk with the gates. There is a long leverarm down to the gate from the actuator. Even if you make this gate work fine, you will have problem when you start install the other gates bechause you dont have the same height between the actuator and the gates. Therefore the leverarm will have different length and that will affect the traveling lenght of the gate opener, also affect the pull out force on the gate opener. To solve this you need to redesign the gate. Instead of having a lever arm you should having a vertical pull from the actuator and a link in the gate to pull it out. That would make equal force and traveling lenght independent of the height between the actuator and the gate.
Thanks for you amazing work so far an to share it to us!
/Johannes
I never heard about a ring tensionner, very smart idea, but it works with chain gears only I guess...
From Johannes to Johannes, so much this!
Especially the last point. My mechanical engineering heart hurts more and more because I feel like martin it slowly but surely digging a whole he can't get out of.
I sincierly hope he can fix the flaws and get over the whole reliability thing.
The "bouncing problem" you describe can maybe also be adressed by tuning the snare to a different note, so the vibrations of the drumskin have a lower probability of positively interfering with double marble drops
@@GoelWCS A flanged sheave would work too for a flat belt/timing belt, probably.
sherlock_norris I concur totally, as a drummer I know the different actions of bounce on different tensions on the drum head, my first thought on the last video was, the double bounce on the snare is causing the miss, this is the only variable change from the video where there was no misses
Martin when you play 1 million marbles you should livestream it
We all wanna watch and be there for that success
Totally agree!!!
Wow, I never thought of this, sounds focking cool!

On the other hand it might make an already-stressful test even more stressful. Just thinking Martin may not enjoy that so much.

Six marbles failed, in a way that is completely harmless to the machine, and you know exactly why it happened. I see that as a total sucess.
Completely harmless? One day a marble will get stuck between moving mechanisms and jam up the machine. The only safety feature in this case is the fly wheel disengage mechanism which will probably put to much force on the jammed mechanism and locally destroy the machine. Failing marbles are always a risk for this machine as long as there are almost no safety features in place. Martin is going to find this out someday. So sadly enough failing marbles are not so harmless in my opinion :(
@@FrankyieFrank I think in actually practical usage he would be able to look for the errors and stop them before they happen. Well, that's what I think.
@@FrankyieFrank Yeah but the thing is that the cause of the fails is not a part that is going to snap of a desing flaw that needs some plastic surgery. It's just a interchangeable part (and too many marbles in my oppinion) that caused the overflow to, you know, overflow.
If one of those stray marbles would cause something to break would absolutely suck, but compared to the other things he had to do this far, I would't even call this a fix. Just a bit of fine tuning.
@@FrankyieFrank Sure, I agree that it could cause a jam somewhere else, and I also agree that the machine needs more failsafes.
But I still think the test was a roaring sucuess.
@@FrankyieFrank I think what was meant is that only six marbles failed due to the test setup: If all instruments are playing, the line of marbles will never back up far enough to flood the stair elevator.

Martin takes out the angle grinder to balance the Flywheel: Me (working for a reasonable time in a balancing company) - thats not how balancing works. I suggest using magnets.
2mins later: Martin uses magnets.
The funny part about this: It wasn't 2 minutes, but 3 days for Martin.
I was just thinking about the little clips they put on tire rims to balance new tires.
@@dmdeemer Same here. I just noticed my tires getting out of balance yesterday. Today I see this and I see the grinder and cringe. Then he fixes it proper and I sigh in relief.
Exactly. It didnt matter if the flywheel was true, it mattered that it was balanced. He was equating true with balanced. At the machine shop they true flywheels so the clutch mates, and then balance them so they rotate smooth and dont shudder.
@@MrAntimonty i
We need a “Look At That CLEAN FLOOR” shirt.
Also, be wary, Martin. It feels, right now, like everything is perfect; but I think there’s a flaw in your logic. You’re testing for stability in an unfinished product. There’s going to be a lot more mass, and shifting of mass, one *all droppers are installed.* Testing for stability before you have initial stability measured is going to make you sad later on, when additional active and installed gates change the dynamic of the whole machine. I recommend focusing on that aspect before running any extreme amount of marbles; especially because it’ll make that test a lot faster and, most importantly: realistic.
I also worry about the world tour. A lot of stages will be portable stages, resting on soil or something. Won't there be lots of vibration in the stage floor with half a dozen people moving around, moving instruments around, etc.? How will he eliminate that?
@@thanbo He won't. The occams razor solution which is easier than everything in the video: Bigger marble catches
@@thanbo The vibration from the audience might be the one need to be careful about. For the vibration from the technician moving around on stage and other musician moving around on stage, there is a simple solution. As the MMX is centerpiece, using a dedicated stage for it is good enough. You know, just like DeadMau5 concert where just for him they made a dedicated stage. MMX don't need that large of dedicated stage, so I think its possible to make a "portable-ish" dedicated stage for it on world tour. For vibration from the audience, yeah it needs more expertise to deal with it.
To be fair though, I think that's one of the reasons he only considers it 0.15% complete. He still has a long way to go!
At least we're getting the angle grinder x flywheel video now, instead of near completion of the machine :P

@@resonantwoods you really dont need to mention that that is a game lol
I am genuinely concerned with such levels of precision being needed that this will not be repeatable when transported without significant setup time
You know, there is always some setup time before a show ... Installation, tuning, tests, and so on ... I'm sure that, with all the works done now, it will cut down on setup time and will be manageable in the end !
Also, having such a high reliability in perfect conditions gives some headroom for errors when the setup is suboptimal on tour. As many have pointed out it's not the end of the world if some marbles escapes during a concert. If 1/10'000 escapes in the studio it might be 10/10'000 on stage with limited setup time. But it makes sense to get it as good as possible now.
At least it could be perfect for studio recordings when je will have the time to adjust everything
Yeah, setting the machine up to be exactly the same each time might be quite the task. I can see different venues having different temperatures and humidity, the machine may also need to acclimatise. I don't know how this would affect the machine working but I'd probably want to do some long running tests in different environmental conditions.
@@isakefternamn it isn't the fact that the machine has high reliability in studio conditions that worries me...it is the fact that it needs high reliability to work properly. As we have seen already, minuscule deviations from "perfect" cause a cascade of issues. It is this very narrow "operational window" that gives me anxiety.
Its cool how not only is this refining the machine to be smoother quieter and more accurate, but its also serving as a sort of break-in period for the machine as well.

*Spoiler alert*😢 😅
At some point, the marbles that miss are going to be caused by a slight breeze coming through the window, and Martin will engineer something to counteract it
Yes. It will be a mechanical fan attached to the planetary gearbox that produces a breeze in the opposite direction of the window.
Quite simple, actually. Just contain the MMX within a vacuum so there's no air to make a breeze! Thinking about it, that might also solve any humidity or temperature change problems. Huh
Connor McInerney there will be no sound in a vacuum tho, having the MMX in its own controlled micro climate might be the go though.
@@alvardo3000 That actually wouldn’t be a problem for most of the MMX’s instruments. The bass has pickups, so it doesn’t need air, and Martin mentioned someone’s suggestion to use magnets with the vibraphone bars which essentially gives them pickups as well. The kick uses a contact mic, so again, no air needed. The main issues would be the snare, hi-hat and cymbal, because those don’t use pickups or contact mics. You can still give them all contact mics, but they likely won’t sound the same or as good. So if you didn’t care about getting a perfect sound, a vacuum wouldn’t be an issue
But... making a vaccum that big is practically impossible, especially on the go in the world tour. He also would need to stand inside of thr vaccum to operate the machine, killing him due to lack of oxygen.

💥💥IMPORTANT SNARE INFO💥💥(coming from concert band percussionist) - I’m not sure if you’re aware of this already but the snare is similar to the vibraphone in the sense that you almost NEVER hit a snare dead center as it gives you a much more dead/less crisp sound and is know as.....THE DEAD SPOT (optimal striking position is usually a few inches from the center). I would be extremely intrigued to see you do some basic tests regarding drop placement on the snare as I think this could greatly improve your sound quality in performances but especially recordings. I hate to be that guy but I feel that this is important since snare is in nearly everything. To anyone who reads, please like and reply to this so he can take this into consideration!! Much love Martin❤️

I have absolutely no idea if what you're saying is true, but I guess it is, so I'm commenting this hoping that Martin will read this :)
Jibbert
@@CupcakePump I'm also a percussionist and can confirm it's definitely true. It's not as big a deal with a snare drum as it is with a tympani (those you _never_ hit 'em dead center because it won't resonate at all), but the sweet spot is almost always about halfway between the center and the rim. Compare that to mallet instruments where you DO want to strike near the center because that's how their resonance works.
Something that may help with those vibrations. To reduce "ressonance", try cutting a couple of holes at the top of the square tubing and filling the frame with sand. Sand will add mass to the supporting frame and absorb part of the vibrations. I recall ToT also did that on his CNC building series.
I'm pretty sure they do the same thing to rollercoaster tracks.

Your runners need to be spring-loaded or you'll run into trouble.
Over time with the runners stressing the belt combined with temperature swings the belt is going to stretch, this is what lead to the problem you have now that made you add runners, by making them static/not adjustable you're just kicking the can down the road, you need to plan for this.
In your workshop things might be okay for months before you notice a problem but on the road? you'll be going from warm venues to not temperature controlled vans over and over, if the van is generally colder than the stage you'll have extra stress on the belt when you're not using it and when you come to use it the belt will be loose again. If the van is generally hotter than the stage then when you're on stage you'll have that extra stress while also being under the load of playing. At some point it's going to stretch and it may cause you to drop from your 99.99999% goal
Yeah, but he can make a auto adjustable runners like in the cars, a spring and a pulley
this has been one of my big frustrations throughout the entirety of the series really.
He'll have a good idea, but then do a half job implementing it. Which then causes problems. Which he'll solve with another clever idea, but once again with a half job of implementing. I get that he has also been learning this entire time, but you'd think with a team of engineers backing him that stuff like this would get caught and corrected.
Belts are probably cheap and readily available enough to just be replaced on the road. Not to mention the main portion of the vibration, which was causing the drops, came from the flywheel being unbalanced. So the belt thing is probably more cosmetic than necessary.
He could make them adjustable, or just use bigger bearings. It's a problem, but not a major one.
And he should only have an idler on the slack side of the belt. He gets half-way there with these designs, but just doesn't have the engineering experience and exposure to fix it once, so he ends up in integration hell.
I love how mechanically inclined this guy is. The spray bottle cooling the flywheel was a good idea

Honestly, even though 6 marbles fell, it actually wasn't 6 failures. The reason being that it was loading multiple marbles and they all fell at the same time as part of the same overflow failure. So reliability is actually higher
There's also the fact that the failure happened obviously outside of normal operation ie. several hours of uninterupted use of a single instrament. If it were me, I would note it down as a possible point of failure while moving forward with the rest of the instuments. It's possible that using more gates at once would prevent this from happening again, or even just the breaks between songs. The cause of the failure may even just be that MMX had more marbles in circulation than it could handle when only playing the snare.
@@DeathOfLife3764 Exactly. Unless you plan on playing it for over four hours, there would be zero issues the way it is.
Using triplet notes will avoid this for the next test.
@@Sorestlor that is why he should do a calculation of minimum number of marbles needed for the machine to play smoothly. As well as calculate maximum number of marbles that the machine can support.
While the probability is low. This was just one of many future gates each with the same potential failure point. So the real failure probability is actually quite high, almost to the point of being certain over the course of an entire concert. In addition, the marble loss is a minor symptom compared to the potential failure of several instruments downstream of the blockage from receiving any marbles at all.
This man has the best hobby ever. This machine will be worth an unimaginable amount of money when it’s done.
Itll all be labor costs
There's no end for this lol,, how can it be done, this is infinity²+1
You are using your brain and life in the exactly the way you where ment to. FREE. I love to hear you talk, the freedom in your voice is remarkable. We all have stressful lives your no exemption. But your contribution to our world will live on forever. You are so appreciated, it makes my heart joyfully for you. Be well and never stop
Well Lordy, we discovered something Martin doesn’t know about- how to balance a car tire!!!!!
Yes, I would have thought balancing the wheels to start with but less entertaining hah
Well ... now he knows 👍
Or how to make use of spreadhseet formulas.
@@Mikenperu how does one do that ?
I think Martin was lucky with this test. If he had stopped 5 minutes sooner, he wouldn't have found the fault. It would come up eventually and possibly ruined the next test.
The test was a success man, it did exactly what it was supposed to do, find a flaw, and thank god it found the flaw right at the end of the test and you didn't have to run another one.
Loving the electronic voice which comments on the clean floor! You're the KING, sir!
I feel like martin needs a crash course in statistics. Also, the simultaneous use of spreadsheets to display information, while using a pocket calculator to calculate things makes me crazy.
Spreadsheets are just boxes to put text and numbers in don't you know...
THIS. Someone teach the man how to calculate with copyable equations
But I like doing my math in paper
My head was exploding on why he didn't use excel to do the formulas. Martin if you're reading this and need help with Excel/Google Sheets, hit me up! I'll be glad to help out :)
Reminds me of my mom who does the exact same.
A spreadsheet is just a handy table to out numbers in, all calculations are done on her physical calculator. No adjustability whatsoever.

Forgive me if I'm wrong, but that last little issue wouldn't actually exist if the machine was playing more then the snare drum, correct?
Yes and no. Assuming the snare channels were the only ones with improper marble heights in the marble divider, then you likely wouldn't see this issue occur, however it still delays marbles from getting to the hi-hat and bass channels, which is an issue this test doesn't show. But if other channels also had improper marble heights, the issue would be compounded as there would be buildups causing and adding to more buildups, so the issue would actually happen *more* frequently
Correct. The solution, the "prescription" if you will: *MORE COW BELL*
Also, this is one of the most complex channels because of the longer parts and drops, so what he learns here will easily apply to rebuilding the other channels.
I believe so as well. He just needs to turn it up to 11.
Not gonna lie, when the bass and guitar came in on the play-along, I literally teared up. It’s just so awesome to see music involving the marble machine actually coming together, after all this time. Plus Martin’s beautiful musical mind generating tear-jerking chord progressions.
I can’t wait to see the million 0 drops video.
I also can’t wait to see it live on the world tour.
This is the most complex and demanding DIY one man project I've ever seen online, your dedication is outstanding, people like you are just so precious for all human race, never stop sharing your genius!!!!
I hate, really hate myself for this comment. When you said that the flywheel was unbalanced, my only thought was! Take it to a tyre fitting centre and get them to balance it or mark it. Sorry.
One never needs to say sorry when stating the plain hard truth.
That whole segment was really painful to watch. Even more painful, considering he worked 3 days on it.
I thought the same. I guess he does not own a car or never got new tyres fitted.
@@sven31415 Even owning a bicycle you might get the odd out of balance wheel and learn the simple fact that geometry alone does not balance a spinning wheel.
Imagine the guy at the tire fitting center angle grinding your wheel to balance it
Just remember this as well: theoretically some problems, especially those with the marble divider, should be less likely once you start using more channels!
Imho I would argue that this is actually good test case to refine for.
We wouldn't want a break/slow down in the song, or if we just shut off a ton of channels for a while, to become an issue. I'm still nervous when i look at the marble divider in terms of capacity. If you ask me, the marble divider should be able to hold *all* of the marbles that could be in the entire machine while running. MM1 had massive marble divider space.
@@sunray501 I mean, it took gradual build up over FOUR hours of constant playtime for the failure to occur, and that was in the edge case of only one channel being played. With more channels seeing use over, let's say, a 10 minute song (probably generous) I don't think it even counts as an issue.
May be an issue if too many marbles are in the machine. Take a few out so there's no chance of that backlog. Or maybe have a reservoir somewhere other than the top of the machine
an overflow condition must be accounted for. depending on the conditions it may actually be *more* likely to happen because of the total number of marbles in the machine; a high "marble flow rate" could cause a failure to cascade much more quickly and cause new/more problems
We're all frustrated at his efforts applied to grinding the flywheel, but the dude is a genius and works way harder than I would. To say nothing about the time spent making the video.
I'm not frustrated. This guy is a musician with no formal training in building or engineering. The amount of things he has learned/ taught himself over the last 3 years is staggering. What frustrates me is the number of actual engineers shitting on him in the comments with short, self important criticisms and complaints :( There's also a lot of helpful, productive commenting, but all the positivity of the comment section circa 6 months ago seems to be gone
It's not really that big of a deal when you consider this is how your car tires are routinely balanced. Only pound on lead weights for regular rims and sticker weights for Mag rims.
Genius work smart, not hard.
@@primtones Entertainers work entertaining, not smart. The solved problem is boring next to the absurd failed attempts of solving it.
I like marbles 🐢
In all seriousness, you my friend are one of the most talented individuals I have ever had the pleasure of seeing in my 35 years of life. Thanks for sharing your talents.
"So how do you tune it?"
"It's... complicated"
takes 3 days to tune lol
oh ya know, 6 magnets
@@conradkai9705 It's actually the same concept behind car wheels. Basically none are perfect, which is why mechanics add balancing blocks on the inside or outside of the rims to stop them from shaking
Tim Pool likes your comment.
Angle grinders and sand paper 😂😂😂😂
"This is my best idea ever"
Almost sets his house on fire
This video came on my recommended 2 weeks ago. “Hey! That’s the marble machine guy!” Two week later, I’ve watched every single episode up to this point. Truly inspired by your commitment and also how this project has changed the way you work. You inspire everyone here to work harder in whatever we do! This is now one of my favorite channels and I hope to go to one of your concerts once the world tour happens!
This man can absolutely take a punch in life with a smile. Amazing engineering, I love it!
Martin: "We have to balance this wheel..."
Me: "Ah, no sweat - the auto mechanics do this all the time using little weights they weld on"
... 3 days later
Martin: "This geometric balancing did absolutely nothing to the balancing of mass"
Me: "are you freakin' serious?!"
That being said - this has to be one of my absolute favorite projects and it's mindblowingly awesome to follow you through all these efforts. To some extent, it just wouldn't be so enjoyable if everything just went nice and completely according to plan. I love all the glitches, problems, terrible decisions and wrong solutions - that's basically how life works, ain't it?
I TOTALLY AGREE!
Success is good, but solving problems is ....ecstatic!.
Seeing all the analysis, observations, thoughts, trials and errors is wonderful .
It shows that even a genius can miss things , or get too focused .
And it shows a positive side of failing....i LOVE his attitude !
This is pure craftsmanship at work ....i mean ....lamenting his welds 😆... I loved that part .....thats an artist - 98% of people aren't even gonna notice the welds let alone even think of them ....and he's going " they're not pretty enough "😂....but he's right.....no matter how small ....each element counts.
And it was sorta funny he did three days of grinding ......and 3 little magnets fixed it😜.....i laughed my ass off 🤣
Weld on? 🤨

Martin: uses an excel sheet to write down diagnostics
Also Martin: uses calculator to do Maths on the data in the sheet xD
Not going to lie, it hurt a little bit to watch him do that. If you're going to be using a spreadsheet, then take advantage of the features of the tool you're using to do all the math for you rather than doing the math by hand and potentially introducing additional error into the data by mis-transferring the values.

@@zeushi Having localized point of sale software to Germany, I can confirm: radixes (radii?) and time formats suck
@@zeushi German here. In Germany, we use comma as decimal separator and the point as group separator for thousands. In Switzerland, they say "comma" but use both point or comma. They also use single quotes or spaces for thousands. In India, they use a decimal point but don't group into thousands, but thousand and then hundreds. So these are different notations:
English: 123,456,789.1011
German: 123.456.789,1011
Switzerland: 123'456'789,1011 or 123 456 789.1011
India: 12,34,56,789.1011
The German format also introduced a problem for CSV files, since comma in numbers are important and not just for convenience in reading, like the commas in English number formatting. Therefore, the "German" CSV files use semicolon as separator.
I think, the world should finally come together and use the metric system with English number formats.
@@NFSHeld Also, in Australia we use 123 456 789.1011, prior to 1970 it was separated by commas instead of spaces. The radix, however, has always been a period, or full stop if you're Australian.

I personally like the mechanical noise, it's satisfying to hear such a beautiful machine run, and for me, the biggest appeal of you channel is watching all the moving parts come together to do something so great.
im the other way around, a machine especially a complicated one running nearly silently is mesmerizing to me.
Well, I must say, you executed that with precision, and brilliance! In all my years I have yet to see someone as focused as you are my friend. The way you were approached with a challenge, and excepted it, with enthusiasm and vigor. Yes, you cleaned that floor perfectly! Oh, and that music thingy, that’s cool too!

I have been extremely lethargic most of the time for years, and outside of work I've not had consistent hobbies in forever. I'd try learning guitar.. and quit after like a week. Get a camera, barely take it anywhere. Try learning 2d art, can't convince myself to ever actually play.
But recently you have inspired me to actually do something. I've been teaching myself CAD and piano, and have been keeping at it for a while, making significantly more progress on both than I have on just about any other hobby I've had in such a long time.
Congrats on this milestone, and thank you for sticking to this project, for posting such great videos, and for not giving up on this beautiful masterpiece of yours.
Who would dislike this? Dude puts so much energy into a machine that’s only purpose is to entertain us.

@@Nevict Or nostalgia inducing old russian/soviet movies, due to the xylophone
You could have saved yourself some trouble with the fly wheel if you would have gone to a tire shop and asked how they balance wheels. The magnet (weight) solution is exactly what they do, except they are clipped or welded to the wheel.
Your work and ability of creating such incredible things are simply amazing. Thank you so much, just for delivering fantastic content
For your final test, you should play your song made by your first marble machine, to honor how you got to the day the machine is finished
That would be epic.
What can you say about a guy creating a machine and his quest for perfecting movement... AMAZING!!! Unique way to show love for music.
It's so cool to see that, now that you have "completed" the MMX you can now focus on how to "tune" it. This has been so interesting, all the ways the machine can fail, and you persevering in fixing it, this is my favorite series on RUclips!
Sometimes when watching these MMX vids it's easy to get caught up in all the engineering details and forget that Martin is such a truly _marbelous_ musician.
How long have you been waiting to use that one? 😄
I get it.
i spent a good 5 seconds wondering how mega man x was relevant

I'm glad the patron and RUclips member counter is going back up! These last few videos have been my favorite (although I've watched all the build videos) and the fact that almost 2,000 people cancelled their membership last month was very sad to see. Keep up the good work Martin, we're still supporting you!
it is sad to see it go down from a motivational standpoint but from a financial standpoint, that's a lot of cash
@@AfonsodelCB That's true, but it's possible most of those are just $1 a month, and I'm sure all the parts cost quite a lot. I wasn't really worried about Martin financially, though. My point was that it was sad how many people stopped supporting him when he changed how he worked and did his videos.
@@jonathanbost8427 Even with all at $1/month that's a lot more money per month than I make. I'm still happy to pay my tiny part though!
@@jonathanbost8427 That might be it, but it may also be that people have less money at the moment due to the whole global plague thing
@@mduckernz You know what, that might be it. What's funny is I didn't even consider that. Maybe that means that not so many people were unhappy with Martin's changes after all.

"The more mass, the more energy it takes to move this..." This prophetic quote will come back to haunt you when the roadies go on strike because the machine is too heavy to move...
Just put it on wheels. :)
@@two_tier_gary_rumain fly wheels?
Get better roadies
It doesn't matter because he make the machine modular.
It wouldn't be hard to add mass in a way such that it can be taken off and put back on again easily. Lumps of iron (or sand boxes) that can be screwed on in specific places, for example.
It is so beautiful to see that science and mechanics can make this wonderful and enchanting to listen at
