My Arduino based alarm clock is making some progress. This weekend, I
soldered together the DCF77 receiver and gave it a spin. It works
remarkably well. I'm pretty confident that I can omit an RTC because

signal is just brilliant.
This leaves me with two big tasks:
o Sound. The Arduino Uno can play basic tones but I'd rather have a
sophisticated, dedicated sound processor.
o A real "boxing". Right now, everything exists only on a
