why go through all the hassle to make things more complicated and not anywhere near as reliable as a basic cable and twist grip?
I'm all for doing what others havent done yet, but some things are just not worthy for the efforts involved and end result.
as well as, having more stuff to hide or try to hide and batteries, wires etc etc when its so simplified and easy and clean and safer as is.
anyways, that being said, good luck and post up progress.
