Alexis Robert - GPLWaker

GPLwaker is an alarmclock with a GPL firmware. It’s based on two ATmega8-16pi, one for the core system, and one for the display board, connected by I2C.

Radiocontrolled (with DCF77)
Can be controlled by a computer (RS232)
No sound chip required, the µc generates the frequency
Big screen
Alarm settings are saved into EEPROM
Clock and calendar are managed by an external RTC clock (DS1337)

Now, the core system nearly works, I have some problems talking to the RTC chip with I2C. I’m currently working on this.

Also, the EAGLE files (EDA & PCB) will be available soon, under GPL. Currently, the prototype uses a Veroboard.
