First experiments with an electromagnetic pendulum.
The pickup coil (a steel bolt with about 100 turns of enameled wire) picks up the passing of the magnetic pendulum. This is then fed into a microprocessor that energizes the coil just long enough to give the pendulum a push.
This is the basis for the next clock I build on the new CNC.
(The Arduino is included purely for blog cred…)
Now I just need to design a suitable escapement…
