I've decided to see if I could build a head that had similar movements to the Madame Leota tombstone from Haunted Mansion using servos.
Eventually, I may build a tombstone for it to go inside.
The first thing I did was come up with the design for the eyes and eyelids on a word processing program (I converted it to .png) and then cut out a piece of mdf to hold the eye and the servos. I ended up having to cut out another piece of MDF to get the eyes closer to the inside of the mask.
I used 40mm ping pong balls with wooden dowels that go through the top so the eyes sit on board.
A few more dowels are glued into the back of the ping pong balls so the eyes can move left and right. Two large paper clips were straightened out to assist with connecting the dowels to the servo.
Before I attached the eyes to the board, I attached "U" brackets which the eyelids are connected to the mdf. A few more large paper clips were used as connectors between the eyelids and the servo. At first I used hot glue to attach the eye lid servo to the mdf, but I decided to make it more secure and used vertical servo mounts.
A small square piece of wood sits just in between the "U" brackets and a pop sickle stick is attached to the little piece of wood to keep the eyes from rolling back, but still allowing the eyes to move.
