Hey all, continuing my PhotoBioReactor project. :)
Need some assistance determining not only what kind of rotary slip ring I need to use but where to get it as well.
Basic overview: I plan on oscillating a vertical shaft 360 degrees over a varied timeframe. This shaft has some aquarium lights vertically mounted to it. I need to power these lights without the cords getting tangled up, hence the idea to use a rotary slip ring to pass the electricity needed through the rotating shaft's axle housing and have a stationary cord to the base unit and an automagical electrified light pole. Of doom.
Needless to say, finding a slip ring supplier (or even someone who knows WTF I'm talking about) has been... challenging. Help?
I need the rotating joint to be able to attach to 1/2" thick transparent lexan, support at least 30 pounds of weight on it (likely need ball bearings), pass enough electric-juice through to power (at full peak power) four fluorescent 24" T8 light fixtures that suck down 120v~277v 50/60Hz each, allow a geared servo or stepper motor to effortlessly rotate the shaft, and preferably not be a pain in the arse or wallet. :P
A work-in-progress Google Sketchup shot of the light-shaft:
Eagerly awaiting enlightenment,
