If you’re the outdoorsy type, perhaps you’ve heard of a pursuit called geocaching, where you try to find markers, or “caches” that have been hidden all over the world. This can be an entertaining way to get out and get some exercise, but once you’ve found the marker, that’s usually the end of the fun.

On the other hand, YouTuber cliptwings’ Hangman geocache is an Arduino device that makes you guess one of five random words to fully open it. Cleverly, the battery is mounted on the outer part of the container, so those that find it wouldn’t be deterred by a powerless unit.

You can see more about the gadget in the video below and other geocache projects on cliptwings’ channel, as well as check out Dan Wagoner’s “hangmanduino” code on which this device is based here.
