One of the best feelings in the world is when one of our posts inspires a fellow hacker to plan, create, and execute his or her own project.
[Russ] let us know about his Frustromantic Box which he gained inspiration from the original Reverse Geochache we posted about. For those out of the loop, the box is locked and will only open in a certain location. The current distance to the location is displayed on the screen when a button is pressed, and usually there is a limited number of button presses (3 presses for those that know geometry, 50 for everyone else). As soon as the box is at location, it will open.
The Frustromantic Box uses an Arduino, classic HD44780 display, a servo, and the pièce de résistance EM406 GPS. All built in time to frustrate his wife for Christmas.
