Reverse Geocache Puzzle

[SJClimber]

This is kind of interesting, if not the adventure, the inventive energy and electronics used for the puzzle. http://arduiniana.org/projects/the-r...-cache-puzzle/

Wish I was as savvy in electronics as this guy. I could see a lot of interest in something like this, especially among the techy-geeky crowd! Thanks for the article. If anyone builds one, I want to buy one...

I heard about this on PodCacher a while back. I didn't quite follow their explanation of it, so this article was helpful to me for a better understanding. Actually, anyone could do this with any geocache, if you could find a GPSr that only had a readout of distance and no directional arrow or map!
