This is a custom PCB designed from scratch in KiCad 8. It takes a 5V input and boosts it up to 170V DC to power Nixie tubes.
The Design
- Controller: MC34063
- Switch: External N-Channel MOSFET (for high voltage handling)
- Layout: 2-Layer PCB with a full bottom-layer Ground Plane for noise reduction.
- High Voltage Routing: Thick traces with high clearance for the 170V output.

Questions
How big is the Nixie clock PCB?
It measures 58.9 × 31.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nixie clock use?
11 parts, built around the MC34063AD. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Nixie clock KiCad files?
From the Chinmaisoorya/nixie_clock repository on GitHub, at the commit this page was made from: the board is nixie_clock.kicad_pcb and its schematic nixie_clock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nixie clock design in my own project?
Its repository states no licence, so its author keeps all rights: ask Chinmaisoorya before reusing the design.
