If you want to display numbers, just go for Nixies. There’s no better way to do that job, simply because they look so cool. Unfortunately, Nixies require high voltages, controlling them is a tiny bit strange, and they suck down a lot of power. These facts have given us a few Nixie alternatives, and [Dave] is here with yet another one. It’s a light pipe Nixie, made from acrylic rod.
The idea of using lights shining into a piece of acrylic to display a number is probably as old as the Nixie itself. There were a few tools in the 60s that used side-lit plastic panels to display numbers, and more recently we’ve seen a laser-cut version, the Lixie. This display is just ten sheets of acrylic etched with the numbers 0 through 9. Shine a light through the right acrylic sheet, and that number lights up.
You can do just about everything in acrylic, and it’s already used for a light pipe, so [Dave] grabbed some acrylic rod and bent it into the shape of a few numbers. With a little work, he was able to make his own FauxNixie by mounting these numbers in a carefully modified lamp socked wired up with ten individual LEDs. The results make for big, big, big Nixie-style numbers, and the perfect clock for the discerning glowey aficionado.
