Oh so that's why my drill doesn't explode when it gets interlocked in something, always wondered how it works

[@michaelocyoung]

Mine always does because I don't play a 80s keyboard while I'm drilling.

[@mbrsart]

It's also adjustable so that you can put screws in without them going too deep.

[@Adventium_]

@@mbrsart it's more so you don't strip the screw head when you drill it in all the way and it stops turning

[@No-pm4ss]

Is it the exact same mechanism in the drill? Using ball bearings and springs?

[@randombloke82]

Anki that depends entirely on the manufacturer and even the exact model. Torque limiting is almost an entire subject in itself.

[@tokay.]

In my imagination. On the world tour you will have a crew of a bunch of people to change the song. And it will look like a formula one pit stop. Edit: When i say f1 pit stop, what I mean is that a bunch of guys come out and they all have one job. E.G Guy #1 changes left song plates Guy #2 changes right song plates Guy #3 changes first half of vibraphone scale Guy #4 changes second half of vibraphone scale Guy #5 tunes bass Guy #6 adjusts the music timing clutch Guy #7 and 8 fixes any problems and get martin whatever he needs (cranking that crank for upwards of an hour will get exausting) Martin entertains crowd All in 10-20 seconds Hope that clears up some confusion Edit2: thank you so much for getting me top comment under one of my favorite youtubers everyone!

M Jons I would think a backup machine could be built exponentially faster once the OG MMX is complete and all testing, tweaks, and final dimensions are in. At that point the cad will be fully representative of the final product, all parts can be ordered/ built with 100% confidence and final assembly becomes the adult version of legos

I LOVE PROCRASTINATION! More please.

[@ExTess]

I told you to add a braking system like this a year ago! Good to see you actually realizing it before something bad happened and someone lost a finger, or even an arm. The torque limiter is a fantastic idea, and I'm just glad you're making safe possibly the most dangerous part of your machine. Keep up the good work, you mad scientist.

[@SurajChandiramani]

You should put a line gauge on the allen key wrench so you can tension the springs equally on the flywheel limiter rather than counting turns.

[@NealD]

Suraj Chandiramani I was wondering if there was a way to equalize them all. Since 1 turn is 1 thread, a line on an allen wrench will be inaccurate. Bottoming out all of the screws and counting backwards, is probably the best way to go about it.

[@vnyggi621]

@@NealD seen that yesterday on a carburetor cleaning tutorial

[@Finnspin_unicycles]

@@NealD You could go and do it evenly by starting either bottomed out, or screws all the way out and counting it evenly. But they don't necessarily need to be equal, if you think about it, so it's not that critical.

[@NealD]

F1NNSP1N I wondered about the necessary consistency. It seems the friction would add up across the marbles? Or will the limiter be limited only to the one tightest marble?

[@Finnspin_unicycles]

@@NealD Somewhere inbetween. It won't completely add up, since due to different tolerances in the hole spacing and since not all marbles will get the same forces. If you have a spline connection, you estimate that somewhere ~70% the strength of the sum of all connection points is used. Due to the springloading, which will make it somewhat more forgiving on tolerances, I'd guess that it probably adds up almost completely in this case.

[@AttilaAsztalos]

What @Marius said; bikes freewheel without any torque being involved in one direction. If your bike would have what we have here, it would try to back-spin your pedals until you would oppose that forcefully enough to trigger the decoupler.

Can we all just take a second and notice this mind-blowing comparison. Marbel Machine mark 1 and then cut to the MMX beast towards the end of the video. The difference is astonishing and breathtaking, at least for all of us who have been closely following this journey. The MMX, already at this stage, evokes both fear and amazment. Just as Martin said - an intimidating mechanical masterpiece. I'm paraphrasing but can't you feel the excitement too?? All the difficulties of this project make it even more worth while to see it to completion and be presented to the world in its full deviant glorry!

[@anderselse6862]

Good work. I appreciate your effort in explaining the physics behind the design, however, you seem to confuse the terms: Torque, Moment of inertia and angular momentum: 0:41 : The flywheel of the toy car gains angular momentum - its moment of inertia is not changing. 1:30 : More weight is not necessarily equal to higher moment of inertia. it depends on geometry as well and more so than mass. what you meant to say is that moment of inertia is linearly proportional to material density. moment of inertia is proportional to the square of the distance to the axis of rotation. 1:30 : Reducing the diameter of the pulley wheel, does not increase the moment of inertia of the flywheel. i suppose what you meant was the because the gear ratio is higher, then you can obtain more angular momentum of the flywheel with the same speed at the crank-wheel. Extra comments: 4:45 : You explain that the ratcheting noise is from the area of the graph after the clutch has disengaged and stays at a constant low torque value. I would say that the noise is from the "marbles" springing back into their seats (or the extra ratcheting mechanism) after the clutch has been disengaged and rotated 1/5 revolution. therefore the ratcheting noise is from the torque limiter, and the graph should not have single ramp, but be a saw tooth :P whose frequency matched the frequency of the frequency of the ratcheting. 15:00 : The extra ratcheting mechanism is in principle the same mechanism as the one with the marbles. The only principal difference is that the second ratcheting mechanism only has a sloped cam surface to one direction of movement, whereas the "marble" ratcheting mechanism has sloping surfaces to both sides. you could just have increased the slope of the marble seat in one direction and achieved the same result, with less noise probably. It is really inspiring to watch the build process of the MMX :)

[@maximilliansummers3725]

I've been following your progress on the Marble Machine X for over a year now, and I am continually amazed and inspired by what you're doing. On top of your more obvious talents, you're an excellent presenter. If you come anywhere near me (Australia) I guarantee you I'll be coming to see you play.

[@outputcoupler7819]

Museum Speelklok hasn't asked for the original Marble Machine already? I am genuinely shocked, it would be a fantastic addition to their exhibits.

[@ManuelGennaroMusic]

They already had the machine for some time to show at their exhibitions and they returned it to Martin.

[@daanwilmer]

They had it, and then returned it. Perhaps the cost associated with keeping it in running condition wasn't worth it (and it's not as interesting without being able to play something).

[@ralphjqa3929]

It was never in playing condition, not even when Martin played it. The original video was made over several takes because the machine would keep breaking down. It’s in an earlier video.

Only 10 more until we reach number 100!

[@leonardoeneria3100]

Heyyy you again!

[@ManuelGennaroMusic]

I see that Justin Y is a man of culture as well.

[@Heggrik]

Jesus, how far you have come. This is pure engineering magic imho. Well done Martin and the boys and girls that contribute to the MMX.

[@Dmanning11]

Can’t you simply donate the original machine to the speelklok museum, I’m sure they would love to have it on permanent display.

[@qwertytwinkletoes3955]

He did a while ago but he got it back

[@Drick10]

Yea they didn't have enough space to keep it

[@jeffro7856]

So beautiful to watch the MMX in action

[@Kazutoification]

7:40 I'm reminded of Megalovania.

[@bradmaggard1996]

"Counter" clockwise. You are awesome Martin.

[@amdnable]

you just made me understand why we use Zener diodes. Yes I'm an electrical engineer...

[@LukasFink1]

I would rather compare it to a fuse or more precise a voltage regulator with over-current protection. But basically I had the same idea to compare it to electronics.

[@umpoucodetudoealgumacoisa]

I'm in the very first year of electrical engineering and I haven't studied those yet... Now I'm curious! Can you please explain why the comparison?

[@telefon72]

Lukas Graphen I second this, don’t really see where the zener fits in

[@hdrenginedevelopment7507]

@@telefon72 a zener when in reverse bias is used like a safety relief voltage shunt. One use is in automotive and industrial microcontroller I/O where you have to protect a sensitive input. For example, a 5V logic level input with a tolerance of 5.5V maximum before damage is done, a 5.1V zener tied to the input line in reverse bias to ground will shunt anything over 5.1V to ground (example, wire insulation becomes damaged and 12V supply touches 5V signal), and the micro input only sees 5.1V and is saved. They are also used in the same manner as a simple voltage supply regulator.

[@amdnable]

@@LukasFink1 I respectfully disagree. A fuse would be like one of the solution they described: a screw designed to break at a certain torque. I see the comparison with a Zener diode that channels the overcurrent to the ground (through a resistor) when the voltage exceeds a certain value. It's a system that rests itself, just like the marble in the coupler.

[@indylux]

I gasped when you stuck a 2x4 into your running machine. That is true trust in your engineering prowess!

[@tommes55]

Martin should be " Q" in rhe next James Bond movie.... 😁

[@peterkelley6344]

That would be ... fun! If not entertaining.

[@paulrichmond6903]

Martin, you have pulled together quite a diverse and skilled team. It’s wonderful to watch whatever you guys come up with. You guys rock!

[@IrishAnonymous01]

Just a warning that you've less than a day to buy a MMX poster on Teespring!

[@BeansproutPost]

Thanks, dude! I was meaning to buy a poster from the beginning, but I got distracted. I would've been devastated if I couldn't buy a poster.

[@catherinecarter3465]

Thanks from me too. Been meaning to order for ages, dashed over and ordered just now

[@MAV98765]

Thank you. Just ordered mine. Didn't realize it was time limited.

[@IrishAnonymous01]

@@MAV98765 I didn't either. I just went on and saw that there was only a couple hours left

[@daryamaysam373]

The MMX keeps getting more mind-blowing!

[@Endermanso]

Imagine LEDs turning on when a note is played, like when the keys light on a Midi. I would love that instead of those fingers. A regular ends switch and some cables should be enough, you could even get the power from an XLR cable that spits out 48volts with a resistor

[@Timooooooooooooooo]

That could be really cool

[@ManuelGennaroMusic]

It would be cool, but Martin has made clear that he doesn't want to introduce any kind of electricity in the MMX. Only mechanical movement. I personally don't mind the fingers, as long as they aren't as floppy as the prototypes he made in the other video. Having them as a solid, rigid piece of plywood would make them look like the ones on the original marble machine.

[@marvin3242]

As a mechanical engineer, this is some of the most entertaining content ive ever seen. Bravo

[@carrievandal]

Please don't sell the first Marble Machine!! You might regret that some day.

[@SlartiMarvinbartfast]

I agree, it's a really bad idea to sell it (or even loan it out again). It's a fragile machine and has already been damaged when it's been shipped around, plus Martin will one day in the future think "I wish I'd kept it" ! KEEP IT MARTIN ! :-)

[@BerlinMauer]

As much as I am madly in love with the original Marble Machine, I agree that Martin should keep his invention or have the Marble Machine in an appropriate museum like Speelklok.

[@Mrcaffinebean]

Very cool! This is the first time I’ve fully understood the flywheel and crank components. Very impressive design!
