Vancouver Island artist Kyle Miller has found a new use for an old technology, using Soviet-era , cold cathode Nixie tubes to build displays for handmade, steampunk clocks. "The biggest appeal of a ...

I'm looking to get a blue "aura"-like glow around my computer. I'm debating between blue cold cathode or blue electroluminescent lighting. I think that the cold cathode is brighter (can anyone confirm ...

Like most electronic devices, televisions do best when kept at moderate indoor temperatures, without exposure to extremely hot or cold weather. However, it may be necessary to transport your cathode ...

Join us on Wednesday, October 28th at noon Pacific for The Art of Nixies Hack Chat with Dalibor Farný! When they were invented in the 1950s, Nixie tubes were a huge leap forward in display technology.
