“Connect” to an atomic clock in space! GPS, DCF77
This project is a clock with radio receivers that can receive the exact time from the GPS satellites or from the DCF77 transmitter. by hkdcsf @ hackaday.io This project is a clock with radio receivers which can receive the exact date and time from the DCF77 time signal transmitter or...
