+rhh.privat Posted November 17, 2013 Share Posted November 17, 2013 Hi everybody, I made a small Arduino based geocache some time ago. I used it to react on beeing hit by a torch beam at night - sending back some morse-code which could be used to calculate the next position of a multicache. Let's say the Arduino-cache sends back the number "308", you could calculate the next coordinate by something like: New coordinates: N50° 43.xxx‘ E6° 06.yyy‘ with: xxx = 2 * gz – 246 and: yyy = gz / 2 + 137 You could even send two different groups in different directions, by providing different formulas :-) Now I plan to redesign the hardware, maybe make a board for the circuitry - if there is some global interest... You can have a look at the dev-story and the whole thing -> HERE! Please let me know, what you think... Cheers - Robert Quote Link to comment
+Butano Posted November 19, 2013 Share Posted November 19, 2013 That is very cool. I have an Arduino. I have been using it to control my Christmas lights, but thinking about some application for Geocaching too. Images of Dr. Who come to mind. But this sounds like a good idea. Like the Morse code portion of the it too. I would be interested in seeing something. Quote Link to comment
