Inside of the Neck Bracket. I milled out two slots for the motor terminals to go into. This removed
the risk of shorts and lowered the motor some. I also milled a channel to allow the power and control wires to exit
below the motor. Click picture to enlarge.

The inside of the brain cup. The 7 finger light wires
and control wires are routed through two of the 3 access holes drilled into the brain cup. You can also see the brass
sleeves used to support the brass push rods for the finger light movement. Click picture to enlarge

Homemade brain cam and brass push rods. Notice that glued into the ends of push rods are nylon screws used as a bearing surface between the push
rods and the brain cam. Also in the picture are the locking collar and 1 of 3
plastic shaft bearings. Click picture to enlarge

Close up of the Delran Brain Cam. I bought a 2 inch long 2 inch diameter stick from Tap Plastics and turned it on my Unimat-3 Lathe, then
hand milled the cam lobes. At the top of the shaft you can see the top of a steel
rod used to hold the Crown. Click picture to enlarge.

Assembly of the parts that go into the Brain Cup. Notice the 2 5-volt regulators mounted to the inside top of the cup; great heat sink. The finger rods external to the brain cup are covered to protect the paint finish. Click

Modified Light Bulb. This bulb has been converted to an LED for low current and low heat generation. Grind
off the bottom and clean out the insides of the base with a Dremmel Tool and cutting bit. Glue in the LED and current
limiting resistor.

Assembly of all the different subassemblies into a working unit requires about 3 hands and a lot of patients.
