Well as I see it, there are a lot of similarities between Wherigo and my idea. So the question is: Is there need of another harware solution, that wants to enrich geocaching. My main question would be: How many geocachers are using such devices. Does anyone know? 1. How many active geocachers exist around the world? My guess was 250.000, could this be? 2. How many per cent use special equipment such as Wherigo and how many percent just use GPS and cards?

Well battery should last for approx. 2 years, since I am no geocacher: What are "Wherigo's"?

What do you mean with signing? Well it all depends on the distance. If you get a signal in a distance of say 2 meters/ 6 feet, it would still require to find the hide. Another solution would be, that you get the signal in a distance further away, but that the coordinates/ the area where the hide is hidden are less clear than usual.

Hi, I am an engineering student of the technical University of Berlin. I am currently working on a project, that is searching for applications for a certain type of chip, that may make it possible to create a new type of cache. The Chip can calculate the distance in meters/ feet between the chip itself and a second, identical chip. Also it can send and receive data with a rate of 1 Mbit/ s. You could use the chip as a cache, which is not accessable by cachers. Instead, the cache recognizes cachers that are closeby (they also have to have a chip) and exchanges data, for instance it could send the content of the log. And also make an log entry in the logfile saved on the cache. Also, it could send digital gimmicks as a reward, such as a Song, Cartoon, or Video. What do you think?
