Chernobyl Cold Cathode Nixie Clock
The inspiration for this clock came from the TV mini-series Chernobyl. This type of display can be seen in episode 5 when the nuclear scientists are attempting to gain control of Chernobyl reactor #4. In the series, this type of display is used to display the core temperature of reactor #4.
This clock uses Russian IN-12 Nixie Tubes. These tubes were introduced in 1955 and were the precursor to what we know today as the LED. These tubes display numerals or other information using glow discharge. These tubes resemble a vacuum tube in appearance, however, its operation does not depend on thermionic emission of electrons from a heated cathode.
