Hey everyone, I'm sure it is doable, I'm just not sure what such contraption is called, to google for it.

Basically, i'm trying to build a pov globe. I already got the motor that makes 96 rotations a second, but i'm not sure how to get power and/or data to the part that will be spinning. Any idea how such method is called or implemented would be greatly appreciated :) Thank you!

Often there is a rotating metal ring with a fixed brush making contact to the ring.

Here is a neat method of supplying power to a rotating globe display, use a audio jack. Also a neat pov globe.
