New Head Board

A new board to control the Raffe's head The new head board has 10 analog inputs for the piezo sensor "petting zones" - an increase from 4 in the previous version. Each input is also given a high-pass filter and an op-amp buffer to improve the signal before it's passed to the PIC. This should allow for more consistent triggering of the sensors.

The board can also drive 6 servos: one for each ear, one for the jaw, and yaw/pitch/roll for the head.

Communication is done over the CAN bus. The PC software has been interfaced with a joypad, allowing the servos to be directly controlled from the joypad!
