Oh cool I didn't know that existed. In my case I don't have to re-energize it because I use an existing mechanical clock.

If you are curious about this sort of thing, look up master pendulum clocks. They were precision clocks that provided electric timing pulses to network of slave clocks or other uses. Afaik they were common in mid-20th century

Here I was imagining you had to wind your computer with a key every morning.

I also got a rotary encoder with the plan to use it with a wind up clock. So maybe one day!
