Nixie Tube Clock Building
Constructing clocks using cold-cathode Nixie tubes from the 1950s-70s for time display. Combines vintage vacuum tube aesthetics with digital counting circuits, requiring high-voltage power supply design, driver circuits, and often RTC synchronization. The orange glow and layered digit stack create functional art pieces.
