Re: Inexpensive Slip Ring for Turret

I agree with the others this seems excessive.

Am curious if one is allowed to manufacture a slip ring using concentric circles of exposed solid copper wire pressed into a non-conductive plate and copper shoes on the opposing plate with a Lazy-Susan bearing as the pivot. I have actually done this before outside of FRC for contraptions but what about on a competition field?

R50 Branch circuits may include intermediate elements such as COTS connectors, splices, COTS flexible/rolling/sliding contacts, and COTS slip rings,as long as the entire electrical pathway is via appropriately gauged/rated elements.

I'm the programming and electrical lead for team 4388 and we are wanting to create a turret for our robot and we hope to make it turn more than 360 degrees. I have done some research on slip rings that can carry enough current and 8 conductors for motors and signal but have had no luck finding any that aren't very expensive, around the $600 range. If anybody knows any good slip rings I'm open to options and alternative methods.
Thanks!

Here is a $16 possibility, 24 rings, parallel some for higher currents
