Questions
How big is the NixieNTPClock PCB?
It measures 181.4 × 77.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the NixieNTPClock use?
64 parts, built around the 74HC7014D, DS18B20, TLC555N and TLP627-4(F). 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 NixieNTPClock KiCad files?
From the bastian-bou/NixieNTPClock repository on GitHub, at the commit this page was made from: the board is Hardware/NixieNTPClock/NixieNTPClock.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the NixieNTPClock 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).
