This is a video of an electromagnetic clock I made. It follows a conventional wooden gear clock with a wind up mechanism which soon became a bind to wind up every other day and required a large drop for the drive weights.
This clock is pendulum driven as against a conventional clock which drives the pendulum via an escapement. Rare earth magnets are located in the bottom of the pendulum and are pulsed via an electromagnetic coil located inside the rear part of the clock. The length of the pulses can be varied using the two buttons at the rear. This allows for the pendulum magnitude to match the mechanics of the ratchet and pawl drive. This means I don't have to wind it and can position it anywhere I choose.
Responses would be appreciated as I am hoping to sell these clocks complete or as a kit. (less info)
