How to Power a Rotating Turret

[sxysweed]

*doesn't read thread*

What I've seen used in various devices (namely cheap RC Car Remotes, Pistol Grip Style) is mounting contacts on the turntable. You have prongs that dip down from the rotating assembly onto a turntable with copper/silver/whatever tracs, one for positive/negative/whatever, so that it retains constant contact. It's like take a Brushed Electric Motor and making it 2-D... You may not have huge current flow, but with silver 'brushes' and something highly conductive for the tracks, along with "Comm Drops*" for use inbetween, you should be able to achieve good numbers for power transfer. Can't be that bad.

*They are used in Brushed RC Cars. Little drops that you drop between the Com(uter) and the brushes. It helps improve output of the motor and keep it running cooler until it burns off. I could see where it is useful if applied as described above...
