As soon as you were talking about where to position each magnet so that they only match up in one position, I was thinking "prime numbers should come in handy here". I was very satisfied when I saw that the gaps between the magnets ended up to be 1, 2, 3, 5, 7 and 7.

The year is 4172. Humanity has achieved functional immortality, all material needs cared for. Ivan Miranda begins work on his marble nanosecond display
I've loved these videos for a while, but the magnetic torque limiter which auto-realigns itself is on another level above the other mechanisms you've built for these projects. That feels like one you could patent and license out, it's such a brilliant solution.
This series should be a must follow for students when it comes to problem solving. It is all about encountering issues and then needing to finding a solution and that means do not try to come up with the wheel, but find out who made the wheel and how it works and how you can implement it to solve your problem.
I genuinely think you are a madman. My kind of madness though, it earned my subscription and I watch every video in the series as soon as it comes out. I hope you keep embracing the madness.
Just wanted to say that I appreciate the thought you give to the aesthetics of your prints even while trying to solve complicated engineering issues. Form is still following function, but that doesn't mean it can't also be beautiful while doing so.
the 7-magnet pattern you ended up with for the torque limiter reminds me of a few mathematical patterns - i'm not sure which would be closest off the top of my head, but it reminds me a bit of prime numbers, the fibonacci sequence, and the golden ratio regardless, i'm looking forward to seeing this project continue - i'm confident you'll be able to make it work fully!
The gaps between the magnets are prime numbers. 1, 2, 3, 5, 7, 7 (I think the last one can be 7 instead of 11 because their aren't enough positions around the ring to have the magnets repeat positions on the 7s) (1 is not prime but the rest are)
@@ChilledOutGuild There is actually a spot in which two magnets are aligned, 7 apart, that Ivan missed. It's at 11:44, but it's a bit hard to pause at the right moment. But indeed if he went with a 11 spacing you'd end up with the 5 spacing repeating one time because the wheel isn't large enough, so it can't be helped.
The whole time he was adjusting the spacing I was thinking "I bet prime number spacings are what he'll wind up with" Glad to see someone else did the work of counting for me 😅
They're the prime numbers of measurement/Segmented numbers (OEIS A002048 - the numbers that are not the sum of any set of consecutive smaller terms), except indexed at 2 instead of 1. The normal 1-indexed: 1,2,4,5,8,10,14,15,16,21... And the 2-indexed used here: 2,3,4,6,8,11,12,16,17,20... ...except it wound up being a little off (his goes 2,3,4,6,8,8,9), presumably because he made the wheel first with only 40 slots, resulting in 2 extra overlapping sets of magnets that he didn't show - the two 8s, and then the 2+3+4 and 9. To have 7 magnets with no possible overlaps, he'd need at least 46 slots, or 44 if he started with two adjacent magnets (so using the first sequence here).
I'm glad the magnet clutch worked out and you have a good spacing. To increase the strength later on, you can add more magnets, but with the opposite polarity facing out so that they won't be attracted to the magnets that are already placed.
Lego has also torque limiter gears. I don’t know how they work, but there are include in any Lego Technic Set to protect the motors. These gears exists with different Nm settings.
Those limiters aren't indexed, when they slip, they slip by a partial revolution, if that was put into place here, the first time the elevator slips it would fall out of sync with the rest of the clock and throw things out of alignment. This one is indexed, so when it slips, it waits for the rest of the revolution and falls back into alignment when it recouples. The single magnet coupling is insufficient to move the elevator, so since there is no coupling of multiple magnets until it completes a full revolution and re-engages all six pairs, you can call this torque limiter as being indexed, as it maintains alignment with the rest of the mechanism.
They are primes, because there's only one way to line them up that many of them will match up. They have no common factors, which would cause there to be multiple ways to line them up.
This is honestly one of my favorite engineering DIY channels, the sheer number of different solutions being brought in makes me so happy!~ I'll be looking forward to seeing the complete clock and it feels like it can't be that far off anymore! Which is it's own brand of exciting!
*@Ivan Miranda* 2:05 Example of use: In a metal workshop school, the metal lades has a gearbox, where one of the gears is made from plastic (instead of metal), so if (when) a student crashes the metal carver into the spinny thing, only the gear breaks & is easy to access & replace, instead of the entire machine breaking, especially to protect it from some hard to make part breaking.
Love it. The configurations for the coupling had me thinking "This would be a nice Advent of Code problem". The marble cyclone at the end is fantastic.
It has to be extremely mechanically complex in spirit of the project, so a giant rotating arm that will sweep the whole room and an auger to wick marbles to centre
@@ivanmirandawastaken This is a hilarious idea, and could be done with really "Dumb" control system where they just drive around randomly when they don't have a marble, and when one, by shear chance picks up a marble, have them drive towards some bright IR light source to drop it off when it gets close.
Every video you think, surely THIS is the video that the clock will be up and running, then Ivan explains a thing and we’re like “of course yeah, the thing” like we have clue what is going on. In the end though we’re glad because it means another video is bound to come out and we get to enjoy that one too
Our dude has been stuck with this over a year .. and is still producing more videos. Not only - has millions of views! My hat is off to your perseverance!
This was somehow the most satisfying episode so far. It kind of didn't really progress the main clock project in a sense and yet added so much value to it. Classic foundational sub-process that would go unappreciated in many projects, even while it's there making things "just work".
Awesome, around 12 years ago, I made my own printer, and one of the first things I designed was a set of magnetic gears, thinking that it didn't exist yet. I might still have an old youtube video up showcasing them haha. Magnets + 3D printing opened up so much space to create magical ideas. I still keep coming up with new stuff daily. I love to see what you come up with next! I still remember watching your older videos like that one time you made a small rover that drove on the beach of La Concha Bay in San Sebastian when it came out. Good times!
Ivan, I wanted to take a moment to say thank you for a very entertaining 2024. I love this series and I hope the new year brings many fun new engineering challenges so we can watch you solve them, as long as you're still having fun that is! Happy holidays, and have a happy new year!
an elegant solution, and a video made that suggest that you just kind of stumbled on to something that would handle the proper configuration on the first try. i love it.
Ivan, your positivity is simply infectious! Watching your videos creates within me the energy to get things done. I greatly appreciate the time and effort you've put into building and documenting this project. Thank you very much for allowing us to witness your triumphs and lessons.
I both want this series to be over because the entire thing works flawlessly (and is going around the world to different science museums so people like me can see it), and I never want it to end because seeing the engineering behind every subprocess is incredibly fun.
At 15:27 in the outro, you can see one black marble going into a white channel. Maybe fully closing the channels would fix that issue. Right now, it is definitely a handy way to access the marbles, but this problem should still be addressed later to ensure consistency with the numbers. I just watched all the marble clock parts and subscribed! I love your content and immediately bought a 3D printer.
I hope you have someplace in mind where this thing can go on public display (like a STEM museum or something) because it'd be a shame to build such a contraption and have it gather dust.
There are various machines I've seen that are basically giant marble runs. They often show up in airports as something to watch while you wait for the plane. I don't think that would work for a clock, though, especially one that's complicated enough that it might get the time wrong. You'd have to find somewhere that people aren't on a tight schedule, just like a museum.
There's something mechanical that is used in high torque conditions to open the clutch of a vehicle. In Italia or is called molla ragno. It Is a particular spring that opens a closed clutch depending from the applied torque. This is thought to avoid the wheel to slip on the asphalt (old mechanical approach used in high performance engines, for instance by Ducati superbike clutches) now replaced by more tunable electronic systems, but it works
15:08 My parents have a central vacuum system (like, the vacuum itself is in the garage and 2” PVC pipes were run throughout the house to little hole/outlets to plug a hose into the wall) and when we were kids, my dad made a similar vacuum tool with a 3 gal bucket and an old vacuum hose (from an old shop vac or something) that we could push the vacuum hose into one side of the bucket lid and vacuum up Lego pieces into the bucket with the old hose on the other side. There weren’t any filters, just gravity, so most of the dirt and dog hair would get picked up and carried out to the actual vacuum and we had a bucket of (mostly) clean Lego pieces to dump back into the Lego bin. He didn’t have a 3D printer back then (he still doesn’t. But I do, so I get sent things to print off), so aside from the hose and bucket, it was all wood and sealed with gaskets cut from old tire inner tubes.
It was fascinating watching how you worked out how to build a magnetic torque limiter with automatic drive phase resync. Even so the amount of try fail try succeed "engineering" involved in this project is not only interesting but also a bit insane.
I hope you know how much joy you brought me with the whole "o-o-o-o-o-o-o-o-o-o-o-o-wan" bit SuperVinlin (the inclusion of madables in the ad read was also hilarious LUL)
This is so cool??? I unironically LOVE a good failsafe, they’re so much more interesting to me than when people trying to build systems that can’t go wrong. It’s better than perfect, it’s SAFE

The magnet gap sequence (shown at 11:39) is a variation on the segmented numbers (sequence A002048 on the OEIS). Rather than starting with 1 (adjacent magnets), he starts with 2 (magnets with a gap of 1 between). So instead of going 1,2,4,5,8,10,14... He goes 2,3,4,6,8,11,12... ...except presumably because he made the wheel with 40 slots first, his sequence goes 2,3,4,6,8,8,9. This causes two possible misalignments not shown in the video - the two gaps of 8, and the gap of 2+3+4 with the 9. To have 7 magnets with no possible misalignments, he'd need 46 slots (or 44 if he started with two adjacent magnets).
Strangely, the sequence starting at 1 isn't always better. With 15 or 16 magnets, the sequence starting with 2 would need fewer slots, and with 17 magnets, both sequences would need 299 slots.
Just when i thought i saw him create the most beautiful invention yet, he pulls out the marble vacuum without further explanation. Absolutely incredible.
this video just got you a new patreon.. I was near the tipping point and you just keep rocking! I can't wait to see more! Your sense of design is just awesome
You could even add some sort of sensor, electric or mechanical, that tells you when the magnetic torque limiter slips (and perhaps even how many times). This might help when debugging, or just testing performance consistency.
When you said you were gonna throw a wrench in the thing and presumably do something to intentionally screw it up, I didn't expect you to literally stick a wrench into it. XD

I hate to ask this, but what is either the second digit that updates every 10 seconds. I love to watch your journey and enjoy your approach in creating amazing things
ya know... it's a good thing this guy has 3D printing. I shudder to think what he would be building if he only had a scalpel, a graveyard, and an assistant named Igor! ;)
that was brilliant. making sure there where only single couples of magnets that connected when its not in the locked position making all other positions equally weak in comparison meaning it will reset when it comes to the locking position :)
Used to have a clutch on conveyors for large clothes hangers systems. so on the face of 1 disc, you have a hole with a spring and on the top a ball bearing, then on the opposite side a groove the radius of the ball, face them against each other and presto. When the torque overcomes the spring pressure it slips and doesn't smash everything(or bend coat hangers in my case) and is easily tunable with different numbers of balls and springs on the face and different spring weights. Might be a nice idea!
thinking of the interesting use for shaped magnets or whatever they are called, so that only specific magnet pairs would attract, and would repel or not interact in all other cases, pair that with uneven spacings, and you could have a torque limiter which would run completely smoothly other than its magnetically locked position

You can change the two magnet spaces to adjust the torque. You can make the bottom or the top shaft a variable spacer for the magnets.
The best 3d printing channel by far
now that what i call progress. so impressed man.
The magnet gap sequence (shown at 11:39) is a variation on the segmented numbers (sequence A002048 on the OEIS).
Rather than starting with 1 (adjacent magnets), he starts with 2 (magnets with a gap of 1 between).
So instead of going
1,2,4,5,8,10,14...
He goes
2,3,4,6,8,11,12...
...except presumably because he made the wheel with 40 slots first, his sequence goes 2,3,4,6,8,8,9. This causes two possible misalignments not shown in the video - the two gaps of 8, and the gap of 2+3+4 with the 9.
To have 7 magnets with no possible misalignments, he'd need 46 slots (or 44 if he started with two adjacent magnets).
Strangely, the sequence starting at 1 isn't always better. With 15 or 16 magnets, the sequence starting with 2 would need fewer slots, and with 17 magnets, both sequences would need 299 slots.
This has gotten so complex. I love it.
So happy that I found this channel. This project is so interesting to watch. Thanks for the great content.
Woo Hoo! Ivan is making steady progress!
The easier quick n' dirty torque meter solution would be a lever arm plus a scale.

Getting tricked by the comments into a 10-month long project (so far) is crazy
I really like this series though, hopefully it'll be done before 2050!
Just when i thought i saw him create the most beautiful invention yet, he pulls out the marble vacuum without further explanation. Absolutely incredible.
I absolutely love this series, everything you come up with seems to fit perfectly, you are incredible keep it up!!
Love your problem solving skill. Epic!
this video just got you a new patreon.. I was near the tipping point and you just keep rocking!
I can't wait to see more! Your sense of design is just awesome
You could even add some sort of sensor, electric or mechanical, that tells you when the magnetic torque limiter slips (and perhaps even how many times). This might help when debugging, or just testing performance consistency.
When you said you were gonna throw a wrench in the thing and presumably do something to intentionally screw it up, I didn't expect you to literally stick a wrench into it. XD
Tu cerebro funciona de maneras que todavía no entiendo, es una maravilla ver cómo solucionas los problemas con soluciones más complejas que generan más problemas y aún así te funciona correctamente….eventualmente, es increíble
I hate to ask this, but what is either the second digit that updates every 10 seconds.
I love to watch your journey and enjoy your approach in creating amazing things
You could also add sensor to the torque limiter measuring rotation on both sides. If it slips, you can disable the motor.
ya know... it's a good thing this guy has 3D printing. I shudder to think what he would be building if he only had a scalpel, a graveyard, and an assistant named Igor! ;)
I think you just invented the first smart clutch! A really inspired idea!
What a fantastic project man...
I just love this build! Keep on the work!
Damn, that magnetic clutch is CLEVER!
that was brilliant. making sure there where only single couples of magnets that connected when its not in the locked position making all other positions equally weak in comparison meaning it will reset when it comes to the locking position :)
I genuinely laughed out loud at the outro because it was so unusually chill 🤣
Used to have a clutch on conveyors for large clothes hangers systems. so on the face of 1 disc, you have a hole with a spring and on the top a ball bearing, then on the opposite side a groove the radius of the ball, face them against each other and presto. When the torque overcomes the spring pressure it slips and doesn't smash everything(or bend coat hangers in my case) and is easily tunable with different numbers of balls and springs on the face and different spring weights. Might be a nice idea!
thinking of the interesting use for shaped magnets or whatever they are called, so that only specific magnet pairs would attract, and would repel or not interact in all other cases, pair that with uneven spacings, and you could have a torque limiter which would run completely smoothly other than its magnetically locked position
I can’t wait till you build the full complete version and put it in a museum
