Let’s see : take a Spark Electron, connect to your R/C plane, truck or whatnot sensors, including a GPS (TinyGPS if one not already in your R/C), power through R/C battery or a separate battery, but also a small solar panel for backup emergency power and … tada … you not only get live telemetry over 2G/3G and possibly WiFi (adding a Photon ?) or even BlueTooth (add something ?) AND now also FIND your crashed/lost R/C vehicle wherever it happens to be especially if the solar panel can get a bit of sunshine from time to time to send a ‘beep’ of help. You could do geofencing and it can ‘call’ for help if someone (wind, water) takes it too far from your BlueTooth or WiFi (short range) or a G2/G3 (long range) (ex: 2 km from where you stood at launch) with built in tracking/polling… Have a camera on board ? Maybe grab a snapshot or movie clip (on demand, especially if G2 or G3) to help with the search and rescue ?
Of course, someone needs to bring all of this together (I am not there … yet).
Any Open Source programmer(s) out there willing or already working on somehting like this ? For Android and iOS ?
