Yeah I will probably need to add an IR horizon sensor - 2 axis - Bank and Pitch (using thermopiles) this will give an absolute pitch and roll value. The main priority at the moment is getting the navigation software working with data from the GPS. That is what the Break out box will be used for - checking the operation of waypoints and the altitude control parts of the program.
looks good, but i suspect you won't get far in the air with an accelerometer alone (too noisy). You'll need gyros, too, won't you? I think 5 DOF is really the minimum for an IMU.
Bare Bones Autopilot circuit. Uses a PIC18F252 (32K flash rom), 20Mhz crystal, Pitch and Bank accelerometer inputs (ADC into pic), GPS input (SPI into PIC), 2 receiver servo inputs for manual control. 3 servo outputs to control model - Elevator, Aileron and Throttle.
I have just started writing the code for this - I will be able to test this with the Breakout box seen in the other photos - Bench test with Microsoft Flight simulator.
