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 ...

The gas inside the tube is probably argon. We should probably not exceed 100 V on the deflecting plates. The Xantrex power supply is only rated to 60 V, so it should be fine. A more user-friendly ...

In a dual-anode tube, each cathode — there are five in all, not ten — connects to two digits each. Which of the two lights up is determined by which anode is active.
