Questions
How big is the NixieScanDisplay PCB?
It measures 156.5 × 67.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NixieScanDisplay use?
106 parts, built around the 74HC595, L7805, NE555 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 NixieScanDisplay KiCad files?
From the profdc9/NixieClock repository on GitHub, at the commit this page was made from: the board is NixieScanDisplay/NixieScanDisplay.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the NixieScanDisplay design in my own project?
Its repository states no licence, so its author keeps all rights: ask profdc9 before reusing the design.
