I had some extra time this week so I decided I'd create a supporting design to use a slip ring that would not only demonstrate how cool these devices are but that also did something useful.


I designed this one using Tinkercad. I am also working on a frame to hold the assembly together and provide a stable base. When I am finished with the designs I will publish them here.

I don't think they are good enough to be on Thingiverse either and they may only apply to people who happen to purchase these 12-channel slip rings from Hardware for Hackers!

Here us the slip ring attached to a prototype stationary mount. I will manually drill holes and mount the motor to measure, then refine the CAD drawing. I don't care if you think that is backwards.
