Great introduction video to the Micro Word Clock by Daniel Roja:
A tiny replica of the famous Word Clock, using only an ATmega microcontroller, a DS1307 Real Time Clock and a few passive components to display the time on an 8×8 LED matrix. The letters have been printed onto a transparent sheet and glued over the LEDs to produce a readable time.
