Make Geo Caching a bit catchier

Probably you all know what GeoCache is. It’s pretty simple – you need to locate some hidden treasure according to GPS coordinates. But what if make it a bit different when you already have a treasure in your hands but can’t open it until you place it on specific coordinates.

So this project is a box that opens when it is located on predefined coordinates. It is based on PIC18F2520 microcontroller which is interfaced to GPS receiver, LCD and lock of course. Device also logs each try to locate coordinates so it makes possible to analyze how good you were at locating these coordinates. So this is great addition to GeoCaching and everyone would probably love to give a try.
