Alas. In concept, that is extremely interesting. But a bit too bare-metal for me; first I'd have to recruit help to design and build it into something one of my computers can talk to. OTOH, I have written successful I2C code; if something like this hardware were a Raspberry Pi HAT I'd have bought one before I finished typing this reply and probably have a test system up in 24 hours. So it's close. Real close. Relevant link: https://www.ntpsec.org/white-papers/stratum-1-microserver-howto/ It would be delightful to add a WWVB radio version of the build to that document. -- <a href="http://www.catb.org/~esr/">Eric S.
