Back in December 2012 I described a project that implemented a NTP clock based on a Raspberry Pi board and a Adafruit LCD Plate. The project answered a need that I had — a two line LCD clock that didn’t gain or lose time because it was synched to the NTP clock system. It worked great for about nine months then refused to start up again after a power failure. The cause of the problem was that the SD card had become unreadable (I suspect that a set of severe storms that caused multiple power failures caused the issue).
I had never fully documented the setup process, and the code left a bit to be desired, so this misfortune became an opportunity to improve on things. I’m happy to report that revised code and documentation are now available. Please see the NTP Clock page for details.
