Arduino DCF77 Master Clock with pulse outputs for driving electromechanical slave clocks - A Master Clock synchronised to the DCF77 radio clock that provides pulses for slave clocks
Arduino powered DCF77 Master Clock for driving electromechanical slave clocks **broken link removed**
See 4K demo video below showing clock chiming 10 0'clock
Features
Arduino 328 Microprocessor is used to decode Time & date from the DCF77 "Atomic" Clock in Mainflingen near Frankfurt Germany
The DCF77 signal is decoded using the fantastic new...
I've made 2 slave clocks, 1st used an analogue 1 using its 2nd hand + a magnet going around to switch reed switch (all powered from 1½ volt dry electric cell), then 2nd used 555 timer & 2 transistor flip-flop & +1 transistor & also reed relay [@ 9 volt] to 1½ volt dry electric cell.
