+DarkZen Posted October 23, 2009 Posted October 23, 2009 "So how about giving a present that demands a little more than simply scribbling a thank-you card; that’s just what Mikal did for the friend who introduced him to Arduino tinkering. He constructed the Reverse Geocache Puzzle, a wooden box that would only be unlocked when within 2km of a location Mikal preprogrammed into it. To make things more interesting, the box only allows fifty attempts at locating the correct geocache position." Here and here. Quote
+Knight2000 Posted October 23, 2009 Posted October 23, 2009 I'd call that a cache puzzle since it isn't hidden in a GEO style. (earth) Quote
GOF and Bacall Posted October 23, 2009 Posted October 23, 2009 Popular gadget. It has at least two other threads going. Quote
+DragonsWest Posted October 23, 2009 Posted October 23, 2009 Had I a GPSr and this box I'd have it open in 3 tries. Quote
+Crafty Turtle Posted October 23, 2009 Posted October 23, 2009 Wow. I wish someone would give me such a cool puzzle. I think it is inventive and unique. Quote
+Chrysalides Posted October 23, 2009 Posted October 23, 2009 It can be made way more frustrating if it merely displays "hotter" or "colder". Like this cache. Quote
