Nixie clocks, they’re a bit of a cliché, aren’t they? But still, they’re pretty to look at.
[Marcin Saj] has completely got our number, and with his Useless Nixie Device has stripped away any pretence of functionality from his Nixie and concentrated solely on the looking pretty part. It’s a box that steps through the display on any Nixie tube through the use of a set of pluggable socket modules, and it’s encased in an extremely attractive lase-cut acrylic enclosure. Internally it’s an extremely simple device, with a trusty 555 oscillator clocking a 4518 counter that in turn feeds 74141 driver. There is a MAX1771 boost converter in there too to create some high voltage for the tubes.
So it’s a pretty device and you can plug almost any Nixie into it given the right adapter. We guess it might be useful if you have a warehouse full of Nixies to test, but beyond that it’s a pretty desk toy. Still, it’s nice to see a Nixie project that’s not just another clock.
