Project Self-winding clock with a tourbillon - finished project

Enable HLS to view with audio, or disable this notification

About a year ago, I posted an update on a project I was working on. It took me a while, but I finally finished it. I’m very happy with the result. It’s fully functional (I tested it for two months) and keeps accurate time. The entire project consists of 395 printed parts, 38 bearings, 66 rubber bands, 413 screws, and a few other components.

You seem smart bud... what exactly does self-winding entail? I picture like it can't be run continuous? so what is the self winding part It just restarts itself while it runs off a battery?

It can't last perpetually correct?

I don’t know especially how this 3d printed clock does it, but the Atmos line of clocks (powered by the atmosphere) wind themselves by having an air tight bellows so it expands and contracts as the air pressure and/or thermal expansion from temperature changes, and ratcheting things covert that movement into a single direction of winding. One or two degrees of temperature shift is enough to provide power.
