صمام سبينترونيك

I was skeptical about the clockwise-only flow, but after mounting it on the outside of my chain it handles counterclockwise current perfectly. Really clever design.

Wasn't sure about the clockwise-only thing until I mounted one on the outside of the chain and got counterclockwise current anyway. Clever little part, and it does exactly what it says about blocking reverse flow.

The one-way flow is exactly what my build needed, and I like that I can run current counterclockwise just by mounting it on the outer side of the chain. Took me a minute to figure out the orientation, but once it clicked it worked perfectly.
