![]() So how can you display more than one symbol per nixie tube? Simple-just stack a heap of differently shaped electrodes one behind the other with insulating spacers between them, and drive the digit you want to light up. When a high voltage is present across the electrodes, the neon gas between them glows a warm orange color. Another electrode (the anode) is in the form of a fine mesh grid inside the nixie tube at the front of the tube. Nixie tubes work in the same way as a neon tubes, but instead of two similar electrodes, they have specially shaped electrodes in the shape of the symbol or digit. Production stopped in the United States and Europe in the 1970s, and continued in Russia and Ukraine into the 80th-90th. A colleague of him began referring to it as ‘Nixie’, and the name glued. A designer making drawings of the device labelled it NIX I, for Numeric Indicator eXperimental No. Actually, the name ‘nixie’ came almost accidentally. The Burroughs Corporation originally introduced these nixie tubes in the 60th. ![]() Have you ever wondered what was used before digital LED displays overtook displays in consumer products? There were cold cathode display tubes in use, or so called, nixie tubes. You may have seen the nixie clocks in old scientific movies from 70th and wondered how they worked.
