GPS time on the Alpha Clock Five with Adafruit Ultimate GPS

Adafruit 1166

GPS time on the Alpha Clock Five @ Evil Mad Scientist Laboratories.

William Phelps recently wrote to us with alternative firmware for Alpha Clock Five, our oversized alphanumeric LED clock/data display kit. His firmware adds two very welcome features: Automatic daylight saving time (DST) correction, and automatic time setting via a GPS module.  It works remarkably well.
Here, we’ll show you how to hook it all up and how to use it.

This project interfaces an Alpha Clock Five (either the classic red or newer white version), to the Adafruit Ultimate GPS Breakout.   For constructing a cable between the two, we will modify a “rainbow” 6-pin F-F header socket cable, and we’ll also need to run one more wire to provide power to the GPS module.
