Thank you for Watching! Tune in next week for more videos :) - Jak na to + styl
Watchmaker here,
You did an amazing job!
Little advice for the discs...
Make them lighter or cross the center one out like you do with gears 🙂
Also friction fit discs are more forgiving regarding alignment
In clocks the center wheel has a clutch system named cannon pinion in Watches... Main purpose is so you can set the time without affecting the operation of the clock
Hope this helps you and looking forward to seeing more great videos like these 🙂
Waaiiiiit. You’re Swiss? 😅 I don’t know why but I always suspected that you’re from Norway 😂
Half and half😉
Fully swiss, been in norway for more than 20 years :)
At first, I thought you were French Canadian.... Until I saw the European electrical plugs. So not canadian.
Is norway better for living than swiss OR it was love 😁
Actually thought he was swedish because of all the awesome furnitures he's been building. I always look forward to your content - always so smart and fresh.
Bigger stepper motor! Just stacking all of these different mechanisms into one machine is impressive in itself. Very cool!
or another gearbox on the stepper
Yeah, bigger stepper motor which has more torque!
Might break those creaking gears instead
@@rexsceleratorum1632 it looked like he didn't need to give it a huge amount of help with his hand, so I'm guessing the mechanism is not close to breaking. With a little more mechanical advantage, the motor can probably do it. Or with a little more torque. I don't know if anything would have enough stress to be worried about it wearing down quickly, but it seems like it's possible it might not be an issue.
@@doctorbobstone The nudge from his hand had significant mechanical advantage so it's not the same thing. There's a bottleneck where he reduced the speed increasing torque, and then reverses it to get the fast motion. He might have to try another approach or use metal for those particular gears which were creaking
I definitely want to see you go ahead with version 2.0. This is a super cool project.
As for your mechanical advantage problem. I think it’s more simple than you might think. You should apply paste wax to all of your gears once you tighten the tolerances. You don’t have to use wax. You just need to lower the coefficient of friction. I’m sure there’s plenty of ways to do that including a change in the materials you build it from. Perhaps even polished 3D printed gears might do the job because you can add lubricant to them.
That's what the bearings were for. I get what you mean though. Surface to surface friction needs reduced. Coating the already made parts would tighten tolerances. The hard part, finding a material that would coat mdf and expand it, and allow for a lower friction. Epoxy or acrylic might expand the mdf and may allow for better movement, those do tend to stick to themselves when held together under pressure. Possibly an aluminum, brass, copper or similar could be used to line the gear surfaces that contact each other.
Me too! Or we just add a second motor to drive the numbers off the hour, but I know, this would make at less cool.
He could use the plastic covering that usually finishes the MDF and grafite powder to lubricate. Making it smaller should help too.
He can use a dry lubricant or a smoother finish to the gears
Kapton tape or adhesive teflon tape might work well.
Making this out of transparent acrylic (in different colours), with epoxy numbers would be really cool.
Well... I think it's really cool even in this version!
@@saveriog.825 Sure, but imagine that all those currently hidden gears are actually visible…
Acrylic is expensive
@@anthonycomes7896 For special occasions. Not a prototyping material.
@@anthonycomes7896 Valcromat isn't really cheap either and the total price for this in acrylic wouldn't be much more than $300 or so, so it all depends on what's "expensive" ;)
Hey, Alex! Great stuff as always and I like seeing a lot of people suggesting ideas about the inner disc. But something came to my mind right after you have shown the 3rd ring. It already has 24 numbers on it! You don't really need 4 moving discs/rings, you just have to adjust your font a little and write TWO digits on the third ring. This will allow you to get rid of that fourth iteration that is so complex and adds a lot of stress on the stepper motor. And you don't even have to adjust anything else, it already does the right motion! As an added bonus hour numbers are now aligned 100% of the time.
true, this would be way easier. good idea
I was thinking the same thing the whole time. Kinda face palming. It woulda worked so well with just 3 discs solving multiple problems. Either way it was cool though. Part of me wishes he timed all his projects so we can actually see the suffering he probably went through, lol.
Yeah... I was really confused at why the fourth wheel existed, the problem with it though is that he can't simplify it without it moving a ton at the end of the day (from 3 to 0) without the same problem as the fourth disk, I just say that cause I think it would look cooler with everything a bit more spread out
The numbers would get smaller, there isn't room for 24 digits on the innermost disc. This could be solved by increasing the offset between the two planes of dials so that the hour dial can be a bit bigger, but that would necessitate a new frame.
This is already being driven with an Arduino and a stepper motor and, hopefully, a Real Time Clock Module. A redesign using two stepper motors - one for the minutes and one for the hours would reduce your torque requirements. Better still use four steppers and tighten your gear tolerance. You'll get much better alignment. Four motors might tax the Arduino's memory capacity. A Pi Zero could certainly handle it. Don't stop now Alexandre. The concept is COOL. Improve upon your design. You can make this work.
Huge Kuddos for showing a project that didn’t end up perfect. Such a cool accomplishment to get there. Keep up the great work
First Step in Engineering: Make something that BARELY works.
Second Step: Refine til it's perfect.
Next version needs the day of the week and the month and the year. To cover a millenium changeover perhaps a car starter motor to drive it? Perhaps compromise with an AM/PM indicator then the hour can be a single disc? Can you add a seconds indicator on a worm drive going backwards and forwards or something?
Brilliant idea for a build. Such fun, deffo one of your best projects.
UPDATE
You didn't mention if you lubricated the gears? Some wax or something could make all the difference. Also If you change the stepper to one tick per second it becomes 60 times stronger if you gear it down...
Never AM PM 24 hour (or fully decimal - 1000 beats!) is the way to go!
Why stop there? Might as well make it a giant Antikythera!
@@steveh8724 Small fry. Sure he can build a Google search engine computer out of cogs and gears.
@@loopinnerthe Or the Conway Game of Life.
@@GregorShapiro This whole channel is a game of life.....
Great video, I would definitely want to watch a sequel where you try to make it perfect.
An easy fix could be to change the gearing of the stepper motor belt, so it has more torque but lower rpm. That way it would take a little longer to turn but it might at least be able to do it.
You literally read my mind. I'm designing a clock that works using a planetary gear train. It's not as complex as yours, but it has some nice esthetics. Also, what if you add a spring which is initially unwound and as the motor moves, it winds it up, later when lager movements need to be made the spring is engaged to help the mechanism. Another suggestion would be the to increase the torque delivered by the motor by introducing a gear train.
I love the idea of a booster spring. It's like a mechanical capacitor.
Came here thinking to make the comment about the spring myself. Glad someone else did, too. If perfectly tuned, the motor would then be doing the same amount of work all the time, effectively "driving" all the discs even when they're not moving.
The gear train idea is good too. Same principle - *always* drive *all* the discs. Use differentials between each stage (they'd have to be somehow asymmetric to even out the torque).
In both cases the existing mechanism becomes a timing mechanism, simply "allowing" the disc to turn every 10m, hour, or 10h/4h.
Nothing but great and respectful comments which I totally support. My 2 cents are having the numbers cut out by the CNC completely, filling them up with translucent PLA or acrylic and shine LEDs through them where the numbers line up to display the time. That way it would even work in the dark. Other than that: very cool project, I absolutely love it. Great effort and very unique and original!
Try to make your last iteration of this clock out of aluminum. Mainly the gears and supports, although it would be slightly louder and heavier the gears would slide better, last longer, and would be able to withstand random dust and debris from wearing them out over time. You might be able to move the motor to one of the inner disks and use gear reductions to keep the outer disks in sync giving the center disc more torque. I am no clock expert, so it may not even work.
Love the great work, keep it up.
Metal gears are a good idea, but moving the motor... I don't think it's possible if you want to keep the step-moving style; for a continous moving mechanism it should be ok, but it will be unreadable.
Less friction if made out of alu instead of mdf as well, that should help too
I genuinely was having a bad day and this video is making me feel better.
I'm seeing combining this with the new wireless LEDs I'm seeing going around (instead of the number frame, light them up), and this could be really fun. Well done.
Oh, that's a great idea!
magnets could be used to snap each number into place. And yes a larger stepper motor for sure. Thank you for sharing your clock project with us .
In the next version the top plates should be partly transparent so you can see parts of the mechanism 🤩
This is awesome. You should make something like the ClockClock 24!
Please please do this again and get it working, this was AWESOME!!!!!
Incredible project! If you choose to refine this and release plans, I would definitely buy them.
I would as well
I would too
I’m in for sure!!
Same here
Also willing to spend money.
Best bit of advice I can add is after you tighten your tolerances if there is still slop add a spring to the aesthetic disc to try and take that slop out; I noticed when you put your hand on the first (smallest) face and pulled up on it it locked all four into alignment
Wow. This gives me some appreciation for what the early clock makers must've gone through in figuring out how to build clocks and watches. Imagine *inventing* this without access to fast prototyping materials like mdf and tools like cnc?
In order to fix that stepper motor problem at the end, you could have the LEFT side of the clock be the side that you read the time on, instead of the RIGHT. That way, the outer ring is the one that turns the largest amount also has the largest mechanical advantage.
AWESOME BUILD! I have an invention I'm working on for 3+ years, and I need more of your "Just Do It" energy. I am now going to look into seeing if a "Geneva Drive" can benefit my gear system.
absolutely incred can't wait to see the finished version
You should build it inside out. So the 0, 1, 2 is on the outer ring. The time would be displayed on the left side then. Not sure, but it might do the trick.
Brillante! me encantó la idea y la ejecución!
I really enjoyed the video.
I have an alternative idea for the mechanism. Basically you make a continuous rotating mechanism, but it winds up springs (instead of turning clock hands), then there is a release that makes the wheel turn by one number. like a pallet fork on an escape wheel.
This way there isn't a surge in required force to turn the wheel. And the escape would help orient the wheel correctly.
it feels like you're reviving a lost art & i'm here for it.
The "0 1 2" disc could repeat the numbers several times to move a shorter distance.
Also if the numbers where cut through showing a black background everywhere except the readout area, that would look clean - but might complicate things a bit more ;)
Really nice project :)
Yes!
I love gears so much, and this is why!
It's so interesting what people can make when they set their mind to it!
This is the first video I saw on this channel and suffice to say you now have a new subscriber. I hope you try this again and try to get the center to function, great job, love the video, best wishes!
You can make those numbers move precisely by using indexing mechanisms on the wheels. The easiest kind is just a weight bar against a rotating hex nut. That provides six precisely-positioned stops (where the flat sides of the nut allow the weight bar to reach its lowest position), even when the nut is being driven by movements that are kind of vague. The down side of indexing mechanisms is that they increase overall resistance if they're added to an existing design. The up side is that you can often have a simpler design which has less resistance in the first place.
This is one of the coolest thing I have ever seen, I am always surprised with this amazing projects and I absolutely love the work.
❤️
failing is not bad , it is a teaching moment, it is better to try and fail then have a idea and never do something with it…..love the video
Awesome project! Do it again!! It would be worth it and you know it!
for the center circle, you could not only add more repetitions of the numbers, but also shrink it a bit (less weight) and have the space freed up by that act as a window to see the cogs behind it.
Im excited for a part two to see it work!
Bigger stepper. I love the giant leap on the 10 hour mark.
Alexandre, This is a really nice presentation to make a very large clock. As a watchmaker I suggest that (in a manner similar to chronograph watches) you added a spring detente. This spring will lock the number to a repeatable location. The shape of the spring is -----------v. The "V" slides over the top of the gear tooth, down the backside, and exactly positioned the time wheel into your window. Also, lubrication of the gear teeth will help with the turning of the large wheels! Friction if one thing we all have to fight against with time machines. Again good job and a real fun presentation!
This is so sick!!! I love seeing people make unique contraptions like this.
This project looks super cool!
One suggestion I would have is to combine the centermost and second centermost disks into one unit. You've already got 24 spots one your second centermost disk, adding the tens digit directly to that disk would simplify quite a few of your gears and solve your mechanical advantage problem. Though it might take away from your aesthetics.
For the aesthetics, make two separate rings and then bolt them together so they're driven as a unit, but appear to be two independent moving parts. The give-away would come once each hour when the first digit ticks over from 1 to 1 to 1 to 1 for 10 hours, then 2 to 2 to 2 for 3 hours... for 0 to 9 leave the first digit blank and nobody will notice a blank rolling over.
Great Project!
Great project!
I love the way it looks from back side. All of those gears motion. Great gob!
What a great clock, looks really nice to see all the gears move!
Crazy, just awesome.
Do it again!! Pleeeaaasseeee!! Such an amazing looking clock
So cool!
Love this...
"Did you know this is what he was going to do with it?"
"Uhhh, no sir. We told him it was great for woodworking. He may have gone a little off script."
"This man is a god." :D
Wow. Just wow. This is phenomenal. Love it!
Very impressive, I liked this one a lot. Really nice to see that everyone experiences hardships learning new stuff as well
Fun! This is cool! I look forward to see your corrected one! : D
Please do version 2! Maybe an annual project? I'll be there!
Amazing effort, would love to see this working and all line up nice!
I want to have one now. It looks amazing
When I eventually save up enough to get my first 3d printer, I want to make a smaller 3d printed version of this. I think I would also make the front disks in clear acrylic so you can see the gears from the front.
I'm surprised you needed the motor, it should have run just off your enthusiasm alone! Awesome project and a great video, thanks mate!
Also, some of your gears that don't have full set of teeth need some restraints when they are not engaged, or they'll get misaligned when they are not connected to the drive force (Geneva gear has that moon-shaped disk for this).
my first comment is not showing for some reason. Numechron is a rather popular rotating-disk clock. you might want to check how the power is transmitted from one disk to another there, might help you to get some ideas on improving your design. some Numechron designs are available online
Great build Alex! Definitely want to see you perfect this thing! 👍
Wait, you already had twenty four numbers on the third wheel, so why did you add the fourth?
It makes it more visually interesting, but changing out the third wheel for one with the numbers 00-23 and scrapping the fourth wheel would give you a working clock like object.
That would definitely ruin the whole look of having all numbers rotate one by one. Also, this would have the clock look cluttered with the 10-hour ring having 0-0-0-0-0-0-0-0-0-0-1-1-1-1-1-1-1-1-1-1-2-2-2-2 on it
@@Rob_65 There wouldn't be a ten hour ring, just a minute, ten minute and twenty four hour ring. (Going 00, 01 02 03 04 and so on upto 23)
@@Jenn-ri4ld That is exactly my point. This breaks the symmetry.
Amazing!
great video. Thanks for making it. I would watch one of the whole process, right from design up.
Sooo cool!
you should add wheels and rail to the insides of the facewheels so they don't brush up against each other, should make it much easier to spin and you can make it invisible, just cut a groove from behind where you add it
I would love to see in a video your design process. Nothing fancy, just screen capture of your design ideas, calculations, sketches and modelling work!
Brilliant mechanism!
Do you think the alignment of the correct numbers could be more precise if there's a constant tension applied to the whole mechanism? Maybe that could solve the problem of the tolerances of the gears adding up to make the numbers look misaligned.
Nice job! Loved your explanations about all these gear tricks
This is amazing!
I had a great TIME watching this.
You my friend, you are a genius!!!
one of the most enjoyable projects to watch so far. This man deserves more subscribers.
So cool
Please make another one with all the mods. Need to see it work. Well done on getting so close to perfect with this one.
Cool project. Most watches use a snail gear and spring to build up enough energy to jump positions.
Wow this is so coool!
Great job for what it is I can't wait until you upgrade and make it work exactly how you're trying to do that I think you can do such great job God bless 🙏🏾
Even though it doesn’t work it’s an awesome idea and I’m sure what you’ve learned from the project is priceless!! 👍🙌🏻
Ambitious! Nice job for a first pass.
This is so awesome, I think you done amazing considering how complicated it is, the amount of time and effort it must of took to make and it turned out pretty cool. I look forward to a follow video👍
Your creativity knows no bounds. I would never make a clock like this but it sure is entertaining watching you do it. You should sell something like this. This would be a great conversation piece at my house!
Well I'll be... a Direct Read watch in clock size. Love it. I'm sure you've seen these, and they're not as precise as this clock is, but it might be an idea to start off slow and then progress. Because in the case of a direct read watch (in contrast to a Jump Hour watch), the arms have just been replaced by a disc. Have a look at the Fossil JR1140 or the Police Speed Head for example.
Id definitely buy a kit of this!
This is a really cool project
If you position the actual time reading on the other side (left) you could have the first gear telling just 0,1 or 2, meaning that the motion would be much smoother and the most stressed ring (1 to 9) would make a tiny increment (proportional to the distance from the motor and the friction it has to win to rotate). Anyway super cool design! I loved it!
Then you'd have to move the drive to the inside gear and work your way outwards, right. Or am I getting your model wrong?
You always have to drive you minutes, not your hours.
Wow.... hats of mr :)
Great video. I love it. Kept thinking if I were making this I'd just use 4 stepper motors, one for each ring. A lot fewer gears, less to go wrong, easier to sort out problems but certainly no where near as cool. Though it could still look the same from the front.
brilliant
Very cool love clocks
you should be cutting all the faces and frames out of plexiglass so that you can see all the gears and mechanisms you worked so hard for, and then have the location where you read the time be the illuminated location when the etched numbers in those panels arrive there.
This is amazing... I would love to see you make more projects like this ❤
I... needed to see this.
I tried building an oversized, over-ambitious CNC cut arduino clock a while back... it failed. And... I stopped.
I've lost my way. I need to find it again. Thankyou for showing me it can be done ❤❤❤
really awesome!!!!!
Dude you are awesome!! Amazing clock!! Best regards from Argentina!
The swiss are amazing with woodcarving as well.
Impressive, Alexandre!
Love this channel ❤️
Use a DC motor instead of a stepper. Just attach a small magnet behind each digit on the outer ring. Then a Reed contact can sense when the digit is in the correct position.
You even don't need any fancy electronics. You can even use relays and a 1/60Hz clock source. Start the motor when the clock source triggers and stop it when the reed contact closes.
This is awesome, I hope you get those little issues sorted out, because I could see this being an amazing clock.
amazing design idea :D
Nice clock love it this will been nice in small version
You should have made the innermost ring be the ones digit of the minutes and worked outward from there. This would make the time display be on the left side of the clock, but if that doesn't bother you, then all the mechanical advantage works in your favor for the later digits.
