[time-nuts] synch for pendulum clock....

This was talked about several years ago, but did anyone get a fully functional design running using electromagnets to synch at one or both ends of the travel?
In the meantime I am using a sensor to measure the time period of the pendulum for this particular new grandmother wall clock and from that, I can synthesize a pulse train from one of the 10MHz lab clocks to drive the electromagnets to cause a subtle synch at the end(s) of the pendulum travel. The pulse train freq is custom for a given clock.
Anyway...... that's my scheme for now.
