Homemade GPS puzzle box puts a modern spin on treasure hunts
We'll readily admit that most Arduino mods tend to be exercises in creativity (and eccentricity) with little real world utility, which is why this one piqued our interest. A wedding present conceived of and built by Mikal Hart, the box you see above is set to only open in one particular geographic location, and the puzzle of it is to find out where that might be. You're allowed 50 attempts at opening the box by hitting the button next to the LCD screen, which in turn gives you a distance from, but not direction to, your destination. What tickles us about this idea, aside from its ingenuity, is the potential to use it without the helpful hints in securing your own valuables. Check out the read link for a full shopping list of ingredients and the amusing reaction to the quirky gift. [Via Slippery Brick]
