Feather NTP Clock

While my obsession with accurate time continues, these days my obsession with avoiding the hassle of resetting clocks on DST/STD changeover and power failures grows.

My original NTP Clock, based on the Raspberry Pi worked just fine, but it really didn’t like power failures, which sometime trashed the SD card, plus it was about $75 or so per clock.

The Adafruit Feather M0 WiFi board has caught my attention.  It’s darned tiny, and very power stingy.  Add a FeatherWing OLED board, and you’ve got the hardware required for a tiny (2.1″x0.8″) NTP Clock that costs about $50.
