Questions
How big is the Yet Another Nixie Clock Face PCB?
It measures 200 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Yet Another Nixie Clock Face use?
79 parts, built around the 74HC237, BAV103, BF820 and PMBTA42. 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 Yet Another Nixie Clock Face KiCad files?
From the afonsus1997/Yet-Another-Nixie-Clock repository on GitHub, at the commit this page was made from: the board is Hardware/Yet-Another-Nixie-Clock-Face/Yet-Another-Nixie-Clock-Face.kicad_pcb and its schematic Hardware/Yet-Another-Nixie-Clock-Face/Yet-Another-Nixie-Clock-Face.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Yet Another Nixie Clock Face design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
