I actually modified a manually controlled set of DIY puppet eyes, to use servos. Hence, I originally performed the steps in a drastically different order. In this instructable, I try to present the steps more logically.
The eyes were made with the following:
- model plane plywood (3mm)
- 2 mini RC servos,
- 1 standard RC servo (another mini would work)
- scrap styrene,
- paper clip,
- small screws
Step 2: Make base
There are two pieces of stripwood glued to the bottom (which can be seen as "bumps" on the bottom edge and in the picture in step 6) that are 1/4" square by the length of the base. They are separated by the width of the mini RC servo cases and are used to screw the servos to the base.
Note the two 1/2" square posts mounted to one side. They will be used to mount the servo that controls the eyelids. They are separated by the width of the RC servo case, are the height of the case and are installed so that the servo arm will be in a direct line with the control arm of the eyelids (See step 2). The eylid pivot point and the large holes are actually made in a separate step.
