+DarkZen Posted October 23, 2009 Share 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 Link to comment
+Knight2000 Posted October 23, 2009 Share Posted October 23, 2009 I'd call that a cache puzzle since it isn't hidden in a GEO style. (earth) Quote Link to comment

+DragonsWest Posted October 23, 2009 Share Posted October 23, 2009 Had I a GPSr and this box I'd have it open in 3 tries. Quote Link to comment
+Crafty Turtle Posted October 23, 2009 Share Posted October 23, 2009 Wow. I wish someone would give me such a cool puzzle. I think it is inventive and unique. Quote Link to comment
+Chrysalides Posted October 23, 2009 Share Posted October 23, 2009 It can be made way more frustrating if it merely displays "hotter" or "colder". Like this cache. Quote Link to comment
