Anyone tried a slip ring?

[Big Ideas]

Sliprings are one of those devices that are a great solution if nothing else will work. It's exciting to see a design working well, but, the design can be very time consuming to do right.

It doesn't help that First is very conservative with wire sizing. If COTS slip rings are required they may be expensive and heave for the current ratings needed.

One possible solution is to hack the commutator and bell housing to an adequately sized DC motor. "Commutators" are segmented slip rings.

We did a slip ring design last year, but it was a short term exercise on the way to a better solution.
