What I love most about it is the simplicity of the magnet. When seeing the thumbnail, i was already over engineering it in my head thinking about how the rotation of the minute hand would be geared up in the center so that it moved the hour one…

[@nafiul.j]

me too . sometimes we just have to think a bit simply about stuff

[@hglbrg]

ha! glad I wasn't the only one.

[@the-shork]

I was a bit disappointed that it wasn't some kind of pulley system

[@yobgodababua1862]

You were definitely not the only one. Bloody magnets.

[@jakubkolcar6789]

exactly. I thought there was system of gears inside the minute hand, which would rotate the hour hand.

[@Craxin01]

I love how this clock works. And it's actually far simpler than the appearance would suggest. Elegant and simple, very nice combination!

[@themidnightbanshee5927]

Magnets, that's a simple, yet elegant solution and way less complex than what I had in mind, which is running a thin rod through the center of the large arm and stick a diagonal gear to it which would spin the small arms diagonal gear

[@supraaznpride]

Do both. Put the magnet into the minute hand and have that connected through gears to rotate the hour hand. That way it would be a true contactless floating clock.

[@That_Awesome_Guy1]

My thoughts would be slightly more complicated, but would give a better illusion. Basically, you just glue the hands to two separate acrylic discs and then attach those discs to two gears like in the video. Then you can simply spin each gear independently which would rotate the glued hands. This would make it look like the hands are just floating there completely.

[@vinno97]

@@That_Awesome_Guy1 What I like about this one is that there is no glare or anything at all. Maybe a tiny strip of acrylic through the diagonal for each of the handles would also work and be less noticable

[@SaltyMikan]

@@supraaznpride That's not really possible, or at least, I would be very very impressed if that was ever stable

well it's a nice clean build & custom enhancement... though I would have appreciated it if you gave a little more of the spotlight to maker Shiura who actually designed, made, refined, & shared this, his 4th version of his awesome "Hollow Clock"... instead of just a super brief mention at the start of your video. ... based on the title, a lot of folks probably assume you actually "made" the clock instead of just "building" it from Shiura's hard work (like keeping the electronics in the base) as evident by some of the comments here. ...anyway ... cheers!

[@srdjanstokic]

How do you set it up initially? Do you somehow advance the minutes until it gets to the right time? A cool addition for the next revision would be to have two hall sensors at the bottom, so you know when the hour and minute hands cross the bottom part. Then you can make it self-correcting, but adding a wifi module and pulling time from the internet.

[@therealjibrano]

lol found the engineer

[@weiliangzhang2214]

simply set the position before putting the upper part on the base, then it will keep moving from there. you can see it at 4:35

[@MrCreeper20k]

I hall sensor would definitely be best especially if the thing gets unplugged. I do think it's interesting though that a lengthy calibration could have it in tune enough for a year. If you assume one full rotation of the minute hand takes 5 seconds, then it would take 12 hours to simulate a year. So a 12 hour calibration process would have it guaranteed accurate for a year (assuming the motor does not change in efficiency, which is a big assumption).

I love how simple yet mesmerizing the design is, like you wouldn't have expected this to work unless you had some engineering knowledge

[@fifis101]

I desinged something very similar to this like 15 years ago. I never made it because 3D printing wasn't a thing back then and getting the parts made in a workshop would have cost $$$$$. How 3D printers have changed the world for the at-home designer!

[@joel6376]

Prototyping is easier, for sure, so you could have worked out the kinks before ponying up the $$. But outside of printing circles I doubt many people want layer lines or nasty looking plastic as a clock, even if it is interesting.

[@GamMngitSssEmoTionaL5953]

​@joel6376 indeed most to dont that's why you can easily and cheaply use electroplating to give it that nice smooth finish look 😎🙏

[@stabbysmurf]

Absolutely ingenious. And a fantastic build, too!

[@lucalauc]

This is great for putting all the electronic at the bottom part. I thought there might be some wires in the upper ring.👍🏻

[@marioeagle93]

When I first saw the thumbnail I tried to take a guess at how this was made. So I thought I would use a couple of plexiglass circles with the clock hands glued on. Each circle has tooth gears on its edge, and those would be hidden by the outer wooden ring. Then the motor would be linked with them and hidden into the base. Cool to know that there was also a different way to make it!

[@santopino756]

Nice idea. When designing a PCB that I know I won't be using connectors, I prefer providing a hole to have the wires pass through or a double hole to use a pvc wire strap.

[@mareksvrcina5279]

This is THE ONE application that truly does require a PCB at all. I understand that this video isn't a PCB design lecture but rather an ad for a PCB manufacturer. Still, I think that it is quite silly.

Mind blown!!! Recently I saw a similar looking ring-clock but in a more classic fassion: there was a static vertical bar comming from the top of the ring to the center, holding a regular clock mechanism. When I saw it I thought it would be awesome if the minute hand was actually connected to the ring and moving, with an adjusted mechanism for the hour hand on the "center end" of the minute hand - a few days later I see this in my Recommended list :D Thank you Algorithm Overlord for that spark of joy! ;)

[@石山-z3o]

This is a reproduction of Jefferson golden hour clock , very popular in US 1950 period. We can still get from US vintage market.

[@sallerc]

Interesting, thx for the info

[@FelixNielsen]

That is quite clever, but if I ever get around to making one, I think I'll limit it to two moving parts, or parhaps three, including a second hand. I'm not quite sure how easy that would be.

[@maevwat]

you could layer 2 discs but friction will be a problem

[@zotzot5]

I remember when I realized something like this was possible! Glad someone who could make it did too! Edit: my idea used some form of mechanical linkage through the minute hand to drive the hour hand though

[@zgrb]

Just looking at the thumbnail, my guess is two motors, one in the center to move the hour hand counter to the minute hand, which moves with a ring around the full edge. That sounds nuts and I can’t wait to see how it’s actually done Edit: oh my god that’s genius

[@lrvogt1257]

Nice variation on a Jefferson Golden Hour Mystery Clock (which I have). The Jefferson has just a motor and the minute hand is geared to the hour hand which is locked to a glass disc that rotates smoothly without steps. The only thing in your very nice design I wondered about is why you glued a red minute hand to a black piece instead of just making that black piece red... but the engineering is ingenious simplicity.

[@nicodanger13]

The black hand give the optical illusion to the red cover that is a little shorter than the main black hand... the end of the black is visually confused in the black ring and the red piece seem floating.

[@a6dulsalam511]

great, but it doesn't really tell the real time, you should add RTC real time clock module or using nodemcu for getting the time from the internet. but still nice to watch

[@sed6]

5:18 You must not have watched to the end...

[@AndrewSpek]

@@sed6 the oscillator on an arduino isn't particularly accurate, will go out of sync by the end of each day, if it's 0.5% it'll be up to around 7mins out of sync plus or minus. Also can drift a bit. Nice idea though, but definitely should use a RTC module if you want to stay in sync for more than the 20 minute demo in the video.

[@thanhvinhle2893]

one way to make the minute hand looks "disconnect" (no touching the outer circle) is to attach the minute hand to an acrylic round gear (as big as the outer circle) and rotate the whole gear with the minute hand attached to it. With the big round gear as a clear background, it will be hard to notice the rotation

Some miniatures are actually available at online sites but they are not like same or either so costly, so its my request that please can you help me with some of your views and ideas with this and creating an ARC-REACTOR which is non-3d printed, cheap cost ,looks and glows same, easily usable, less problematic.

saw a version of that the other day, it had both hands mounted to an acrylic plate and being moved by magnets. but it was bulky af, probably so that the magnets don't interfere? this version is much more elegant!

[@StuartRobinson123]

to have both hands floating separately from the frame, you could spin the actual plexiglass for one hand, and use magnets for the other

[@luigimaster111]

I feel smart for guessing how it worked from the thumbnail. Ultimately though, easy guess, a magnet is pretty Much the only possible solution for this form factor. You could make the hour hand a circular pane of acrylic with a hand glued in or painted on it and rotate that, but that ruins a lot of the magic.

[@Omegajunior2658]

Wow that is amazing! I love it! I'd say you're pretty good at making things, aren't ye? Greetings from Ireland 🇮🇪

[@PicklesTheOtt]

Would it be possible to build this, but have the hands mounted to a piece of acrylic in the middle, with no signs of support, and BOTH hands controlled by magnets? Or would the magnets interfere with both hands operating independently?

[@anonymousAJ]

Would interfere, but maybe you could have the long hand magnet driven and the short hand linked by 12:1 gearing

[@phunkydroid]

One controlled by magnets, the other by the acrylic piece rotating.

[@JollyChilly]

Very nice build... would you mind sharing the rotor cover with hour markings as well?

[@spavliskojr]

Theres a vintage 40s-50s clock called the golden hour clock that looks similar but done mechanically. the hour hand moves by gravity and a gear box in the center.

[@kisupantteri]

Aa it used magnets for the hour dial. I think it could be made with just gears running through the minute dial too. Nifty project

[@OrangeC7]

That's actually a pretty awesome idea But now do it with the minute hand floating, too.

[@Produkt_R]

That is going to drift out of time very fast. You should add a RTC.

[@Produkt_R]

@@fernandocanogonzalez6034 it's a real time clock. For more precise time keeping.

[@Mange070]

And just add some sort of led on or around the outer ring for the seconds.

[@snowcatman]

I like it. I am wondering if you can take it a bit further and add a metal seconds hand and do the same thing gearing the magnet with the minutes hand. Making it a bit more of a floating realism effect? Maybe add lighting so the the effect looks more real to everyone that its floating in mid air. what a allusion. Thank for the KZbin video.

[@nick-leffler]

This project is great. It's one of those there where it's simple and makes sense, but it just messes with your mind.

I thought he would glue some hands to acrylic discs and rotate them, but this design is much more ingenious and is actually hollow.

[@1983sergev]

"Perfectly accurate" is pretty strong word there, with how loosely fitted those simple plastic gears are it won't be long before it fails on accuracy... Altogether a fun project for kids that want to get into 3D printing and a great promo for the chinese companies selling the electronics, magnets and printers, but hey, to each their passion.

[@albertoctavianuscandi7299]

You can use another method for better accuracy of time. Days after days, months after months, using Arduino alone will make more error in time calculation. So, another method is to use RTC module, which is more accurate. Another method is to update the time periodically using internet.
