Some time after my 1 month South America trip I deve into robotics (q1 2015). In this time I've built a number of cool gadgets including an h6 uav and an x4 uav. Currently I'm compiling code for a kinect sensor so I can attach it to my h6. Anyway, Raspberry pi is pretty cool although tricky to do advanced things with. If you're at all interested in them I strongly suggest you check them out and I'm happy to help out with whatever I can.
