For this project you will need:
1 - Arduino board
1 - Breadboard (anysize)
2 - Servo's I used Futaba S3003
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
Aluminium Shims fabricated on the spot from bar aluminum
Threaded Rod (or a bolt with head cut off)
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.
Step 1: Hardware Setup
For the first step start with a well drawn out plan. Keep it simple. Servo 1 is for the X-Axis. Servo 2 is for the Y-Axis (see picture).
"Keep it simple servo" - Christen Gundersen
Next you will want to start marking out on the plexiglass, or piece of wood, etc where the servos will be and where the eye brackets will be.
Everything starts with a good plan!
