Adafruit customer Kenton Harris used a reverse geocaching box to propose to his girlfriend (she said yes). After the project build and successful proposal, he shared how he built the reverse geocache box with us. We thought others may be interested in building a similar box for their own proposals, or for fun!
A reverse geocaching box works similar to other geocaching devices. It will guide you to certain coordinates on earth and instead of finding a geocache located at those coordinates, you carry the box with you, and it opens for you at a predetermined destination. This is also a great way to do a scavenger hunt (making someone go to multiple locations before the box opens).
Thanks again Kenton for sharing your story and tutorial with us!
