Automaton eyeballs with 2 Arduino-controlled mini-servos

Now got 2 servos going.



Left/right is controlled by mounting the eyeballs on a sort of parallelogram hinging, with the servo attached to the connectors to convert the rotary action to a shear.

Up down is controlled by a bike brake cable attached to the other servo.  This is loose connected to the eyeball rig and converts the rotary action to a push/pull

Automaton head

The eye-sockets for these deodorant-ball eyeballs are cut from the containers, and have been glued in place into the MDF head using hot glue. The glue has been finished with MDF dust before cooling completely, to blend the glue into the rest of the board used to make the head

Because they are translucent, they glow weel with backlighting.

More or less finished automata head

This shows the head with both halves together
The head actually comes apart like an easter egg

This starts like this...

Then occurs some most enjoyable hacking and shaping with various power and hand tools:


Power planer

Hand saw

But best of all the solid tungsten carbide rotary rasps in a router with its cage taken off, and replaced with a drill handle. This is not good for the lungs or the tips of fingers if one is not careful

Recreating the automata head from MDF templates

Having cut out the layers of the head, the middles were cut out so tha when they were stuck back together, they would have a convenient void inside for putting things in



Next these were glued back together. This was done in two parts. The front (face) section was recreated from the foremost 4 layers, and the rest of the head (back) from the rest of the layers:



This shows the stepped effect of the recreated head. This could be improved by using much thinner layers, for example ceiling tiles.
