Edge-lit Nixie tube is sheer brilliance

It’s not often that we see something so brilliantly simple we’re left reaching for our checkbooks while wondering exactly how we never though of that before. [Jürgen]’s edge-lit Nixie display is one of those builds.

[Jürgen]’s modern take on a Nixie display uses ten laser-engraved pieces of acrylic to emulate a Nixie numerical display. In the base of the display are 10 LEDs, each shining onto the side of a piece of acrylic. When an LED lights up, you can clearly see the corresponding number. Edge-lit displays are old hat, but talking about the possibility of an RGB Nixie-style display is really neat.

The build was inspired by an antique edge-lit display that performed the same function as the ever-popular Nixie tube with 10 miniature light bulbs and light pipes. The ancient edge-lit displays came in a rectangular enclosure that worked very well for panel-mount uses, but [Jürgen] stuck to a more traditional cylindrical orientation. All we want to know is when a manufacturer in China is going to start building these. Check out the demo of the edge-lit Nixie after the break.
