Hi there!
Just a suggestion: I would appreciate you to develop an autopilot circuit to use with drones. There are several projects over there, and I cannot wait for yours! ;). Although almost all projects are open source (like ArduPilot) Olimex' circuits are more hackable and have a very good quality. Also, almost all projects are more RC-enthusiast oriented instead of electronics-hobbyists oriented. I'm pretty sure you would do a great job.
Regards!
