Ringing in the New Year with a simple project whipped together in a couple of minutes. I salvaged an old edge-lit display from a multimeter (vintage about 1965) and threw a few blue LEDs into the display sockets. They are controlled with an Arduino mega, using PWM to do the fading.
Bought it on eBay about 10 years ago. They are now extremely difficult to find. I fear this will only get worse due to increased interest and people snapping them up...
