Reverse Geocache
A while back, a friend of ours asked if we could build one these for him: Reverse Geocache Puzzle Box Since I like a challenge, I went for it. I ended up using the EM-406A GPS module from U.S. Globalsat, a standard Arduino 328 board, a backlit 16×2 character display from Futurlec.com , and the Pololu soft power switch from Sparkfun.com . The code will be cleaned up and posted soon. Here are some pics of the build and completed project: Initial board: Original post: http://blog.shop.23b.org/2010/04/reverse-geocache.html
