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.

[@darrennew8211]

Exactly. I was thinking either primes or fibonacci.

[@justingolden87]

Yeah would fibonacci work? Phi is "the most irrational number" and the ratio between the fibonacci numbers approximates phi closer the higher you go

[@battlemasterbrian]

Came here to make this exact comment. Finally something in common between magnets and cicadas!

[@ouzoloves]

@@darrennew8211 The problem with fibonacci is that the wheel only had a very limited number of positions, and the way fibonacci scales, you would run out of room quite quickly.

[@haydenc2742]

i think even the occasional 2 magnets in line will still be a viable torque limiter/magnetic clutch....only when it lines up with 6 or 7 does the "torque" really increase heavily Very very very cool!!! He should really look into magnetic gears!

[@BramBiesiekierski]

Could easily do it without a single "onnnne" just by using prime numbers spacing

[@JusDoc]

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.

[@darianleyer5777]

I think that's been done already, but I totally agree.

[@billkeithchannel]

Martin Molin: TAKE NOTES! @wintergatan

[@MikelNaUsaCom]

yep, the magnetic torque limiter would be great on the tank or the skateboard.

[@Lintary]

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.

[@SeanHodgins]

That is insanely cool. You still need a little robots whose only task is to drive around picking up marbles.

[@linecraftman3907]

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]

Hundreds of them!! And each robot only can pick one marble at a time!🤣

[@SeanHodgins]

@@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.

[@entropic-decay]

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!

[@ChilledOutGuild]

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)

[@Sulphur_67]

@@ChilledOutGuildit’s not 2 it’s 3 no?

[@esuelle]

@@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.

[@alexkaiser4569]

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 😅

[@MH_Binky]

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).

[@kentswan3230]

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.

[@Rulerofwax24]

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.

[@properprinting]

"After watching that, it will still make no sense to you" is like you're reading my mind😆 I'm loving this man!

[@ternilapilli]

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".

[@A38-d7y]

that's a genius contraption! Simple and elegant solution, to quite sophisticate problem (as it seemed in the beginning). Probably my favorite in this clock so far!

[@markswayne6326]

This was particularly brilliant-which is saying a lot. Great series. Loved the introduction of the marble vacuum at the end. I think there’s a good chance that the display will wind up being even bigger than the tank.

[@Za11oy]

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!

8:54 editing is getting much better. That build montage was very satisfying.

[@JeffreyWestOnGooglePlus]

[@FedoraMark]

I love the evil grin energy at 12:53 after you realize it won’t break and want to go for more.

[@veitkunz9524]

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.

[@Avetho]

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.

[@Leron...]

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.

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.

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.

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.

[@sebbes333]

*@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.

[@ScriptCoded]

I was thinking just the same 😄

[@darrennew8211]

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.

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.

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.

[@kylek29]

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.

[@darrennew8211]

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.

[@FaithfulPixl]

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.

[@maxper75]

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
