LED CLOCK — retro HP led displays

clockhp2 clockhp3

 

I built this clock several years ago with an atmega8 and lost all the files in a hard disk crash ( now all my stuff goes to github !!) The core is now an arduino nano. They are too cheap not to use. I did use the Arduino environemtn to code it since I want it somewhat sharable.  I have been thinking of making a replacement led board for these displays. They are quite expensive now, but could be built from discrete 0402 leds ( but somewhat larger than the originals.)  The could also have a serial interface to use less pins on a controller)
