Hillary & Norgay GPS device is a portable device that supports tracking nearest devices and provides functionality that alerts other devices in its range if it figures out that other deivces are too far or user presses panic button. The project is inspired from the lack of cellphone signal dependency in smartphone in the wilderness & the high price of already existing GPS devices.
Current prototype uses ATMega328p uController, Software Serial GPS, I2C 4x20 LCD, I2C Compass, Serial XBee module, Photocell ambiance light sensor, Buttons, etc.

Use a Unix-like system, have gnumake, avr-gcc and avrdude installed. Windows might need some love, but command line would probably work.
Depending on the board, modify BOARD_CHOSEN in src/Makefile.
$ cd main/
$ make
$ make program # Flash the device
