Questions
How big is the Nixie clock PCB?
It measures 164.5 × 121.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nixie clock use?
57 parts, built around the MC34063, L7805, IN-12B and MPSA42. 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 midasgossye/NixieClockHardware repository on GitHub, at the commit this page was made from: the board is nixie_clock.kicad_pcb. 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 midasgossye before reusing the design.
