[Udo] decided to build a clock using the DCF77 radio module seen above. This of course has been done before: the hardware draws a clock signal from the atomic clock in Braunschweig, Germany. So he ...

Here’s a sunrise alarm clock that keeps perfect time. It was designed and built by [Renaud Schleck] who also published a post detailing the process. As you can see, a series of white LEDs inside of ...

A popular project among microcontroller aficionados is to build a radio-controlled clock. Tiny receiver boards are available, with a pre-adjusted ferrite antenna, that receive and demodulate the DCF77 ...

The project is a DCF77 radio clock receiver that uses USB to connect to the host computer along with a small 8-pin ATtiny45 microcontroller and smart firmware AVR-USB & AVR-CDC for programming. The ...

NetTimeLogic’s DCF Master Clock is a full hardware (FPGA) only implementation of a synchronization core able to synchronize other nodes via DCF signal ...

NetTimeLogic’s DCFSlave Clock is a full hardware (FPGA) only implementation of a synchronization core able to synchronize to a DCF signal encoded as P ...
