I am testing my new 3 axis skull. Just the Nod and Tilt servos are in the skull. I plan to put a Pan(rotate) servo in the chest along with arm DIY servos using DC motors. I am using Pixels for the eyes that I am waiting for some Pixels that will fit, the Jaw servo is close to the eye sockets so I will have to use the Square pixels. I might change the eyes to 2 RGB LEDs
