Ie the gear down to generate minutes/hours to tell time is also what creates the leverage to control the dynamics. The range this trick works goes from Big Ben to desktop size. And then you switch to a balance wheel oscillator instead of gravity, to go down to wristwatch size.

Anyone who gets this kit built and ticking smoothly on first attempt is some sort of mechanical genius. I’ve gone: 10s, 30s, 55s, 5 minutes, 25 minutes, 55 minutes, 4.5 hours, and now back to 20-30 min range. I suspect it’s the spring force wind-down.

Yup. Rewound to full tightness and it’s going steadily again. I may be down in the noise zone of friction. It’s not a specific sticking point. To test this, I’d have to note all gear positions at each stall. Should be uniform random?

I’ll measure this, but after first stall at 4:30, with each gentle impulse on rocker it went for a shorter interval each time. By the time it was ~1 minute, strength of initial impulse was determining the duration so pendulum was driving, not spring.

Looks like the spring is maybe not actually designed for 24h
Well let’s see how long I can get it to run, and how much energy is left in the spring when it runs out.
I’m guessing 5-6h with my slightly shoddy assembly, maybe 10-12 if perfectly assembled.https://twitter.com/Knipps/status/1306438464175403008 …Show this thread -
New record: 4:59....



Damn thing couldn’t scrape through to 5 huh
I’m gonna call this done. Looks like this is actually close to the spring limit. Probably only has another hour of juice left tops, if I keep rejogging the rockerShow this thread -
