New simpler electronics

I have bought a fine bag of potentiometers. How sad!
Lots of potentiometers
They are presumably culled from some beautiful old stereos, but anyway...
Automata head with circuitry
Here is the more or less final circuitry. I have decided not to tackle the power issue about servos only getting  current on a change of signal. This is a cop out, but it's time to move on.

however, I have introdcued a transistor to step up the current to the eyeball LEDs.

This does make them a little brighter
