Hi Olin and guys.

I have a feeling that there is way to transfer AC power
to rotating board without any contacts. Am I right ? ;)

The only problem I can see is start up... thought.. if power
consumption is linear function to speed of rotation it looks
easy to stabilize on both sides. Or feedback thru some code,
probably manchester, which is easy to send thru "decoupling"
transformer.

Nice project to improve mechanical skills ;)

PS.

Also how to get rid of opto sensor of "null" position ?
