After reviewing and scouring the internet like most hackers I decided what I wanted wasn't documented well. So I set out to not only do the project for myself but to also try and get some sort of documentation.
For this project you will need:
Electronics side: 1 - Arduino board 1 - Breadboard (anysize) 2 - Servo's I used Futaba S3003
Hardware side: 1 - Set of eyes (ebay, I specifically looked for realistic acrylic doll eyes that had the cornea bump in them). 1 - Set of RC Car half shafts 8 - EZ connectors* 4 - Servo horns (All of mine came with my servos) Connecting rod (various sizes and thicknesses) 1 - Sheet of Plexiglass/Acryilic Sheet (I used this as my base. Only because I had it on hand.) 1 - 12" length of Aluminum Angle Bracket
Assorted Extras: Aluminium Shims fabricated on the spot from bar aluminum Screws Cotter pins Threaded Rod (or a bolt with head cut off) Nuts 2 Part Epoxy
*NOTE: The EZ connector hole sizes are determined by the thickness of your connecting rod. I was lucky enough to have an RC Hobby store down the road so I purchased what was on clearance If you buy the wrong size you could always attempt to drill a bigger hole in the EZ connector but it may be more of a pain.
