Coffee can alarm clock

This Instructable shows you how to build an Arduino-based alarm clock inside of a Illy coffee tin.

The electronics are based on Wiseduino (Arduino clone with DS1307 real time clock on board), with a LED matrix shield sitting on top. The shield is built with 74HC595 shift registers that drive two bi-color (red, green, and orange by subtraction) 8×8 LED matrices.
