Ping Pong LED Clock
February 2nd, 2011 link to (permalink)
Mike Szczys from Hack a Day built a Ping Pong LED Clock, Mike did some nice woodworking on the box to give the clock parts a nice case to shine from. A AVR microcontroller the heart of the clock and a Maxim DS3232 and a coin cell are used to keep track of time.
