Night — Nixie

: A key topic in these circles is "cathode poisoning"—a phenomenon where inactive digits become coated in sputtered material. Modern builds often include a "de-poisoning" cycle that scrolls through all numbers to extend the tube's life. 3. Cultural Presence

: The glass tube is filled with a low-pressure gas, usually neon. It contains a wire-mesh anode and multiple stacked cathodes shaped like numbers. nixie night

: When a high voltage (typically 170V–180V DC ) is applied, the gas surrounding the selected cathode ionizes and glows with a distinct orange-red light. : A key topic in these circles is

: Participants learn to handle the unique requirements of Nixie tubes, such as high-voltage power supplies (boost converters) and microcontrollers like Arduino to drive the logic. Cultural Presence : The glass tube is filled

January 2014 Build Night: EL Wire Nixie Tube - Instructables

A Nixie tube is a cold-cathode gas-discharge display used for showing numerals or other information.

: Projects often emphasize aesthetics, using materials like oak, acrylic, or brass to contrast with the vintage "steampunk" glow of the tubes.
