A little update since the last time this was floating around….I was looking at the front grid on the computer one day, and it struck me that 3 mm LED’s would fit perfectly into the front grid holes. My first thought was to have my name in shining diodes on it, so I measured and drew up a blue print in Illustrator. After thinking a while I came to the conclusion that a clock would be cool. Said and done. I bought a clock radio, took it apart, and figured out how it worked. Link.
