Voltmeter Clock Timelapse

Short timelapse video showing my Voltmeter Clock working over a 90 minute period compressed into 40 seconds. This hi-lights the synchronization pulses from my Master Clock and re-synchronisation of the Voltmeter Clock as it drifts out of sync. The clock drifts as the 20Mhz crystal driving the PIC microprocessor is a terrible time keeper.

My Master Clock is synchronized to the "atomic" DCF77 clock in Germany.
