Questions
What parts does the Nixie clock use?
602 parts, built around the PCA9624BS, AOZ1280CI, ASE-10.000MHZ-LC-T and LD1117S12TR-HXY. 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 limpkin/nixie_clock repository on GitHub, at the commit this page was made from: the board is kicad/nixieclock.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 publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
