This Clever DIY Briefcase Only Opens When You're at the Right GPS Coordinates

Illustration for article titled This Clever DIY Briefcase Only Opens When Youre at the Right GPS Coordinates

The case is called a reverse geocache and it can only open when it's in a certain spot in the world. It was made with a metal box, IKEA door handles, nixietubes to display distance, a GPS sensor and an Arduino.

It looks like a pretty complicated project (the paint and IKEA door handles as bars do a good job to add to that), but I love the idea of reverse geocaching. It's like the perfect gift box. [Arduino via MAKE]
