The first presenter at last Thursday’s Dorkbot Austin was a gentleman named Mikal Hart, who described his “Reverse Geocaching Puzzle.” Designed and built as a wedding gift for an old friend moving to France, the box incorporates an Arduino with a custom shield. A prominent button on the lid, when pressed, returns a distance, in kilometers, on the LCD display (if a GPS signal can be acquired), and counts button-presses up to 50 attempts. No directional information is provided, so the box must be moved about in order to triangulate the location it wants. Mikal also included a cunningly-disguised back door to allow it to be opened in the event of battery failures or bugs.
