Being selected for the geocaching build is fairly awesome.

It does raise the challenge of exactly what to build.

My partner is a geocaching fanatic - but is often cursing at the handheld dedicated GPS unit she uses.

Often it fails to provide a good position fix, its hard to download web based cache location, the UI is rubbish and the batteries drain faster than you can say 'do we have any more batteries'.


My initial thoughts are to use the Pi + GPS (obviously) combined with one of the very scrumptious 4DSystems touch-sensitive displays and a PAN board to get internet access from a mobile, add a camera to this to allow the user to take photos for earth caches and other requirements where imagery is required.


I'll mull over these challenges and solicit some customer input....
