Robot builder Kelly designed this excellent AVR Treasure Chest, and used it to send his sons on a high-tech treasure hunt:
When my boys were very young, I made a treasure chest from a cheap toolbox, placed an electronic lock in it (AT90S1200) and sent them on a treasure hunt, solving clues and ultimately opening the chest to get their pirate booty, a pair of N64 games. Over the years that chest has been used on many such hunts, created by myself or the boys.
Fast forward over 10 years later and I felt it was time for a new chest, one that would run the treasure hunt itself, playing videos, sound effects, and even hand out paper clues. The typical scenario would start with the chest playing a video clue on the iTouch, which would send the treasure hunters off looking for more clues and eventually get a key. Returning to the chest they would insert the key which would signal the chest that they completed that scenario and it’s time to start the next one, which could be another video, or dispensing a paper clue or map. Once the last scenario was completed the chest would release the big spring loaded trunk latch and the treasure hunters could reap the reward of what ever was inside waiting for them.
