I have been working on/off on an autopilot to use in RC airplanes. The goal is to fully automatically take pictures of an object like a house, construction site, etc.

I made the hardware in last year's Christmas holiday. During the year I spend a few hours writing the embedded software for it (in C, works much faster then assembly).

The hardware is super low cost: The PIC dsPIC30f4012 is very cheap and still has enough memory and speed (30 MIPS) to be self sufficient autopilot.

The goal for this Christmas holiday is to do in flight testing of the hardware and stabilization routines.
