GPS and NTP Controlled Binary Clocks

A project that displays the time in Binary-Coded-Decimal. There are two variants: one is Atmega-powered and can set itself from a GPS receiver, and one is a shield for a Raspberry Pi (and therefore sets itself by NTP via your Internet connection).

They look pretty, teach you to read binary at speed, and are a useful timepiece. Great for the electronics or programming geek, and for annoying everyone else!
