Here's a quick test of the PCB electromagnet, snapping the hour hand into position. It works!
This is just with a lab supply.
I designed a controller PCB for this too, and even got it manufactured. I don't think I'm going to bother populating it, though. If I ever come back to this, I'll have to do some serious thought about how to get a powerful enough battery into that tiny package.
Shelved! I have lost interest in this, for now. I'd love to get some better photos and videos, but it's all currently buried in a box now.
