About Nixie Tubes and Nixie Clocks:

Nixie tubes are vacuum tubes displays widely used in electronic equipment during the Cold War Era.
Developed in the mid '50s by Burroughs, nixie tube displays were the very first electrical numeric displays.
Nixie tubes utilizes the phenomenon of glow discharge of neon gas when high voltage is applied.
Their principle of operation is basically the same as a regular neon lamps widely used in light switches.
One major difference is that the nixie tube uses ten cathodes-digit resembling handwriting numerals.
During Cold War Era nixie tubes were commonly used in first computers and measuring devices.
In the late '80s nixie tubes were superseded by more modern LED, VFD, and LCD displays.
However, in post-Soviet Union states nixie tubes were still being mass-produced till the late '90s.
New Old Stock nixie tubes (NOS) can be still found in old military surplus warehouses in Russia.
Unlike LED, VFD or LCD displays, nixie tubes have this unique, mesmerizing and mysterious orange glow.
Nowadays nixie tubes are once again revived in unique clocks, which bring memories of the Cold War Era.
Because of this nixie clocks are increasingly popular among steampunk and retro enthusiasts.
