A battery powered GPS reverse geocache backpack.
This version corrects a minor problem in the prototype that prevents programming with the LCD attached. It should be fully functional.
Power draw from two 1.5 volt primary cells is 150 mA when operating, 1 mA standby. With AA alkaline batteries, that should be a combination of 10 hours operating or 90 days standby.
Firmware is available from http://github.com/nsayer/GPS_Pack
The GPS module is the Adafruit Ultimate GPS module.
