We’ve seen a reverse geocathing box earlier. So this one is even more fun as it has more great features. Deluxe reverse Geocache box is built around Arduino Pro 3.3V board which is interfaced with 20 channel Helical GPS receiver and a big LCD.

When puzzle is solved a box dispenses a key which allows unlocking it. And the last thing which is really great – camera. It takes random shots of the current user trying to solve puzzle. Seems that reverse geocaching turns activity upside down – probably next box will be with map on LCD so you won’t need additional GPS locator.
