How to Build a DIY Nixie Clock From Scratch A DIY Nixie clock from scratch requires combining vintage vacuum tube physics with modern microcontrollers to handle the high voltages necessary for that classic orange neon plasma glow. Originating in the 1950s, Nixie tubes (cold-cathode displays) do not use filaments. Instead, they utilize a fine wire mesh anode and ten individual number-shaped cathodes stacked back-to-back inside a neon gas-filled glass bulb. When a high electrical potential is introduced, the gas surrounding the active cathode ionizes, producing an aesthetic warm glow.
Building one from scratch means designing the logic, assembling a boost converter power supply, writing control software, and fashioning a custom enclosure. Core Components and Tools
