Keychain GPS finder

gps keychain navigation

With a user interface consisting of two buttons and a three digit display, the GPS finder guides the user back to a saved location. Nine locations can be saved for navigation recall. Press a button to save location and press another button to recall. Each switch has a secondary function, for management purposes such as memory indexes and power features. An AarLogic GPS 3A module and AVR microcontroller make up the guts. With the popularity of Geocaching, this would make an impressive trinket; Leading the hunter to an undocumented treasure.

Great project, I will build it, I intended to build something like this for a while and in fact already have a very tiny, very suitable GPS receiver specially bought for this purpose.

Can you also share the ATMEGA88 Hexfile with me? I would prefere to first make it work with the compiled code before I start experimenting….
