Thought it about time I posted something about my new project, which is all about getting way too many sensors airborne on something interesting. I've flown fixed wing models before (many years ago), multirotors look like more fun.
So far I have a PixFalcon, a Pi2 and Mega 2560. The Pi2 provides redundant connectivity (WiFi & 3G dongle), streams video from a camera module & mavproxy telemetry to a laptop running QGC. All good stuff thats been done before.
The Pi2 receives control inputs over Bluetooth from a PS3 controller (if directly connected) or 3G/WiFi from the groundstation laptop if thats where the controller is. This goes over USB to the Arduino Mega, which converts to S-Bus and streams to the PixFalcon - giving 18 channels to play with. Right now its set up to give 6 flight modes, remote kill, primary flight controls, RTL & I can set/clear trims & works quite nicely. I'll have to think of something for all the extra channels to do.
All this is running on a 12v power supply (on the kitchen table). Missing parts are motors, ESC's, battery and frame so there's plently more to do. I'm considering a T-6 with a 5500mAh 4S. The range of available parts is limited here in Chile but I found some D2830 Motors and 30A ESCs that may work - opinions welcome.
Above is a pic of what I've got going so far - next step is the frame.
