The canonical way of using pendulums as time reference in electronic circuits, is to use magnetic pendulum coupled a special circuit (a bjt and an inductor) that would not only sense the pendulum but also reenergize it.

- wkjagt 3y agoOh 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.
- zokier 3y agoIf 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
