DIY Reverse-Geocaching Briefcase

By Chris Scott Barr

Here’s a really cool idea. Let’s say you want to give someone an item, but you really want to make them work for it. There are many ways you could do it, but few as interesting as this DIY reverse-geocaching briefcase. What does it do? Well it can be programmed with specific coordinates, and will only open with the briefcase is actually in the listed spot.

The case uses an Arduino, GPS sensor and some cool-looking nixie tubes to pull off this feat. Once the location has been programmed, it will use the GPS sensor, then display the distance to the location on the tubes. Once you’ve gotten to the spot, a motor will release the latch holding it closed. Expect to see something like this in the next James Bond movie, only with a bomb as the contents.
