Making eyeballs

Here's a prototype eyeball mechanism, built to try out in practise how to make eyballs move in any direction, by using 2 controls - one for up/down and one for left /right.

This is a test to see how it might be done in an automata.

The left right is controlled by a pivoting tube (cut from a ball point pen), and within it is a cable that controls up and down

the round casing limits the degree of left/right movement of the eyes when in an up or down position, and limits up and down, when in a left or right position. This means the casing should be square not circular

Cutting eyeballs

Obviously, why make the eys, when you can cut some off old deodorants. (Keeping old deodorants isn't weird is it?

...and fitting control rods in the back
