I've been doing small hobby iterations of gps nixie clocks for a decade. I'm using a pi in my latest iteration, but man this project really goes the distance. It does everything I want to do in my most ambitious vision of the project and then goes another 50% further. Really excellent stuff.
I am waiting on a board spin for my current VFD wall clock/rss feed (I screwed up the HV grounding) but this project is on such a different level. The project itself is cool enough that the nixie portion is just a side note, whereas every other nixie project is explicitly about using them for display. This would be cool on a 7-segment.
I thought I was being fancy by syncing to time.gov and using NIST's atomic clock, but having an independent atomic clock is awesome. Granted, it's likely not as accurate, but for a wall clock the difference won't show up for centuries. Just the best parts of hobby electronics, a nerd project that is extremely technically impressive for a result that non-hobbyiest people shrug their shoulders at.
