The clock was originally designed as my Senior Project to complete my Electrical Engineering Degree. A number of years ago, I remember reading about a technique to individually control a large number of LEDs with a relatively small number of I/O lines. I immediately thought a good use of this technique would be to make a clock with 180 LEDs. It would have 60 LEDs each for seconds, minutes and hours (which would increment every 12 minutes). It never became much more than an idea in the back of my mind until I suggested it to my instructor for my Senior Project. He responded that he would accept the proposal if I added an alarm feature.
The clock generated so much interest, I redesigned it, fixing all the issues, and made a bunch of them. And now, you can buy the kit at my website, LEDClockKit.com, or at Tindie!
It looks like a luxurious watch with diamonds, beautiful!
