I want a clock that's made out of 7-segment LED Displays, but blue ones instead of nasty green or red ones. Blue ones are available at Digikey. The thing is, the volatages are different for different collors, which isn't to big a deal. The other thing is most the alarm clocks I've taken apart seem to have custom displays built in, instead of the single ones that look like this: http://www.rohm.com/news/images/la-301bb_bl.jpg Does anyone know of any clocks that have the single block version of the 7 segment inside that could be hacked? Or does anyone know of how I could build a clock that would be designed to use the single block 7 segments?
