The neck bracket is made from a $7 copper plumbing reducer soldered to an old brass lamp base I got for free. That's a small PVC pipe section on top with notches filed out for the motor mounting tabs and channel for wire to flow through. Don't waste a lot of money on parts you'll hardly be able to see anyway.

Me and my big 'ol head. Crown and sensors still to be added.

I followed the link on Dennis Wilbur's site on how to convert a computers ATX power supply. It's worked great so far and what's more after the rebates at CompUSA the power supply only cost $2.99.
