Barry shared his NeoGeo GoBack Machine project on the Adafruit Forums:
…The case is made from two 2″ x 3/4″boxes from the Container Store. They are bolted together bottom to bottom with the same screws that mount a USB charger in the bottom, which also holds the 500 mAh Li-Po battery and on-off switch. The top holds a Neo Geo Watch sandwich – GPS, Flora, magnetometer, plus a pushbutton. The battery also powers the GPS’s VBackup pin. I’ve dubbed it my NeoGeo GoBack Machine.

FLORA NeoGeo Watch: Make your own LED timepiece! Use FLORA and its GPS module to tell time with a ring of pixels. A leather cuff holds the circuit and hides the battery. The watch is chunky but still looks and feels great on tiny wrists! The circuit sandwich becomes the face of the watch, and you’ll use a tactile switch to make a mode selector. The watch has timekeeping (one LED for hours and one for minutes), GPS navigation (customize your waypoint in the provided Arduino sketch), and compass modes. (read more)
