Quartz clock pendulum movement teardown with schematic.

I wasn't expecting the circuitry in this unit to be so clever. It's using standard discrete components, but in a very clever way that allows the coil to push and pull while also sensing and synchronising with the pendulum movement.

It's worth buying these movements just for the pendulum kicker module.

Here's a generic eBay search link to the UK site:-

If you see a listing that you like but want to buy it from the com site, try changing co uk to com in the URL.
Target price is around $2.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
