Imagine telling someone from the 50s or 60s playing with their lego bricks that you could make a fully functional clock out those in the future. Super creative project and well executed as usual, although I think absolute reliability is not achievable with mere lego pieces, maybe if they would be swiss lol. So 4000 cycles and 3 seconds per hour seem like an absolutely acceptable margin.
@DefinitelyNotEmma I believe acceptable reliability is actually achievable. I created a similar design that has been running non-stop for over 4 months now. Eliminating the seconds display will allow the Hub battery to remain charged, and the accuracy issue can be mitigated in software.
@@darrellaldrich8334 Sure, but how does it relate to my comment? This Sariel's clock is not functional. Period. Other, more functional LEGO clocks exist. Double period.
@@krzysztofmatuszek Sorry, I believe I was replying to @DefinitelyNotEmma Hopefully, my post makes more sense in that context. I edited the post to make it clearer.
To make it affordable, more silent and power saving: remove the seconds, and use a Technic Hub (4 ports) programmed in Pybricks. You can then set the time using Bluetooth.
Wouldn't you still need to change batteries pretty often? I don't think LEGO has a current product that allows a wall power connection other than the soon-to-retire Mindstorms Hub. I agree though: Remove the seconds display to make it smaller, quieter, more reliable, and practical.
Wow, this thing is soo much bigger than it looked on the WIP photos! Maybe if you don't gear up the seconds motor, it'll draw less current and the battery will maybe last longer.
The sound reminds me of older films, such as the ones by Chaplin, where people work and move by the sound of the clock in their company to make industrialisation look bad. The accuracy is very impressive. Keep it going👍
This is awesome! I wonder if you could use an arduino or raspberry pi to run the motors/code, to overcome the power drain issue. That would require a non-LEGO component though, so maybe not 😋. Super impressive project, great work!
Very cool clock. I would like to see a version with only hours and minutes. The bobbing colon (this thing --> : ) indicates seconds, so it's not really necessary to have the extra track for the seconds digits if this were to be used as a clock. 3 seconds per day is actually pretty good accuracy, well within the realm of what mechanical wristwatches back in the day would get. I think removing the seconds belts would also improve reliability, since it seemed that got stuck pretty often.
Using 100% Lego pieces, there is a way to use AC power from your house electricity to directly power modern Power Functions and Mindstorms motors and bricks without the need of batteries. All you need is an old train set power station an old Power Functions motor compatible with that power station, and a new Power Functions motor. Have old motor spin the new motor and the the new motor now becomes a generator.
@@searme Better control of power output. Can spin the newer motor (now generator) slower for less voltage, or faster for more voltage (wouldn't go too fast or could damage the motor, but it can be spun fast enough to safely put out more power than it otherwise would require to operate). For example most new Power Function motors require 9v but can be safely spun fast enough to produce up to 12v. You can manually modulate the power output by either using the dial on the train set power station, or by mechanical means, such as gear ratios getting the generator to spin faster or slower. You also bypass the battery completely, as the USB charger only provides power directly to the battery, and everything connected to the Mindstorms brick then takes power from the battery.
Hmm. Familiar :) I made a similar clock with just hours and minutes programmed in Python last year. The Mindstorms clock functions appear to wrap after about six days, so I had to add a wrapper function to compensate.
I didn't know the new Mindstorms set could control up to 6 motors, and the motor from factor finally looks decent! I'm kinda wondering if I should get into it again after slowly loosing interest ever since NXT... I do love the challenge of reducing motors though. For example, you probably could get away with just mechanically coupling the 0-6 display, reducing two motors, one for each the seconds and minutes display. You also only need one direction, so you could multiplex one motor to drive one output when going clockwise and driving both output when going anti-clockwise. (Or perhaps just one output at a time if it requires too much torque.) This way you could perhaps reduce the whole thing to 2 motors. Though speaking realistically, it is already not reliable enough to be practical even with 6 motors. Dropping the seconds display would let it run a couple of days instead of hours, so that would make it more usable. Having a sensor to detect if the display toggles could allow you to try to run a "get unstuck" routine, say trying to wiggle the belt back and forth before continuing. It would also help preventing the time from drifting. Perhaps you could let it automatically go the the correct time after manually getting it unstuck if it fails to do so itself?

You never cease to amaze. Easily one of the best channels around. Also, you got me back into Lego after 20 years so I can never thank you enough!
Glad to hear that!
Uuhhj
HOLY CRAP! Thats gotta be the best lego clock I've ever seen! It looks almost like an actual clock too! If this were a real lego set, I would buy it.

That's definitely NOT a functional clock. People make purely mechanical clocks out of LEGO, ones that run for over 24 hours.

What I'm getting from this is that if you abandoned the seconds counter, you could make an actual functional clock out of this
Once again, Another great Creation by the master of technic
All hail Sariel!
It would be a perfectly good clock even without any seconds indication, and then it would run reliably much, much longer.
“Only slightly bigger than your average wristband”

Unbelievable clock!
Someday I want put this clock on my desk.
Nice job
It works better then expected :)
Similar to normal watched and the number of gears needed .. this works great
Sariel mechanic clock will be in next batch of Lego Ideas final review. So excited, hope it can get approved.
Great! Now build a fully mechanical LEGO clock. That's a rabbit hole, though...
It’s been done
I did: th-cam.com/video/f20X0adLF3o/w-d-xo.html
Just unbelievable work👍👏👏

Amazing!
Might use this idea for a GBC ball counter 😊
Looks better than I expected, but it's huge. Anyway I wonder if this is the direction where the Ideas clock could go.
Lovely clock!
Gosh Sariel, this must have taken you so much TIME.
Definitely interesting design. I wonder if using less motors would help with the trickle charging problem.

Timelapsing so fast the ones digit in the second rolls backward really messes with my brain
Great job!
Amazing I have only one thing to add: leave the panels of, skeletonize it :D
You are a genius.
Next project: a mechanical wristwatch 😅. Just joking, brilliant project as usual.

did you lubricate moving parts at all? I imagine the seconds would start wearing out parts after a few hours otherwise
No, that's cheating.
I want a lego clock now!
Fantastic!
😊 потрясающе!
6’s with tops good
amazing!!
When it fast forward the clock 2:59 i saw the seconds display scrolling backwards 💀💀💀💀
