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
 the Arduino has "okay-ish" timekeeping  functionality  and  the  DCF77
 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
      breadboard.
