The renaissance of Nixie tube popularity amid the nostalgia surrounding older tech has made them almost prohibitively expensive for individual projects. Seeing an opportunity to modernize the beloved devices, [Connor Nishijima] has unleashed this new, LED edge-lit display that he has dubbed Lixie.
We featured his prototype a few years ago. That design used dots to make up each character but this upgrade smooths that out with sleek lines and a look one would almost expect from a professional device — or at the very least something you’d see in a cyberpunk near-future. The color-changing Neopixel LEDs — moderated by a cleverly designed filter — allow for customization to your heart’s content, and the laser-cut acrylic panes allow for larger displays to be produced with relative ease.
The image above (and the video below) show two revisions of the most recent Lixie prototypes. There is a huge improvement on the right, as the digits are now outlines instead of single strokes and engraved instead of cut completely through the acrylic. The difference if phenomenal, and in our opinion move the “back to the drawing board” effect to “ready for primetime”. [Connor] and his team are working on just that, with a Tindie preorder in place for the first production-ready digits to roll off their line.
Considering that Nixie Tubes were originally considered too expensive for mass-produced items like clocks, it’s ironic they’re seeing a revival in hobbyist projects for just that purpose. Lixie, then, may fit the purpose for those seeing a cheaper solution without sacrificing on the quality of the result. The design is fully open-source, so get to hacking!
For a suitably cyberpunk application of a Nixie tube, check out this motorcycle speedometer. Oh, and lest you think we’re duplicating ourselves, there was another edge-lit Nixie-alike project featured here just a few weeks ago. Seems good ideas come in waves.
