Questions
How big is the NixieClock PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NixieClock use?
53 parts, built around the SN74AHCT125N, 74HC595 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 NixieClock KiCad files?
From the kseebaldt/nixie_clock repository on GitHub, at the commit this page was made from: the board is kicad/NixieClock/NixieClock.kicad_pcb and its schematic kicad/NixieClock/NixieClock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NixieClock design in my own project?
Its repository states no licence, so its author keeps all rights: ask kseebaldt before reusing the design.
