Nixie tubes have, for years, always fascinated me. The orange glow, the shape of the digits and the depth perception they create when changing from one to the other. Not long ago, I decided to purchase a watch with Nixie tubes for myself.
One of the most notable persons to own one is Steve Wozniak, co-founder of Apple.
Nixie tubes are cold cathodes produced from the 50’s all the way to the 80’s. Nixie tubes are used to display numeral and/or symbolic information by using an electrical charge to let neon gas create a warm-orange glowing plasma.
This means that, contrary to a incandescent light bulb, the filament of a Nixie tube itself actually does not glow or get warm.
