The Nixie tube, a neon-filled tube with a series of 10 cathodes shaped like numerals, is a classic display for any build wanting a unique, vintage, or steampunk aesthetic. We shouldn’t be surprised a factory in China is now turning out Arduino-compatable Nixie modules (English translation, but don’t get your hopes up), but there it is.
The modules are based on the QS30-1 Nixie tube capable of displaying the digits 0 through 9, and include an RGB LED behind the tube for some nice additional illumination. According to the manual, the modules themselves are based on a pair of 74HC595 shift registers, and are ‘stackable.’ By applying 12 volts to a pair of pins and connecting another 5 wires to an Arduino, it’s possible to drive as many of these Nixie modules as you’d like.
[Paul Craven] got his hands on a quartet of these modules and is planning on building a steampunk style alarm clock as a personal project. [Paul] was able to get the modules up and running fairly quickly, as seen after the break.
While they’re most certainly not the cheapest option, if you’re planning a build with Nixies, this probably is the easiest way to get a vintagey, steampunkey numerical display.
