Yeah there isn't anything available as far as a shade goes. A friend and I designed and printed some corner pieces which I Velcro'd on. Expanded PVC was cut to fit in between them. Check the build thread if you're interested. I could probably find the files for you if you want.
As far as the controller I just bought
this cable and wired it into the controller per the instructions. It did not work at first so I whipped out the old volt meter, and for whatever reason the way it was labelled was backwards. Swapped the leads in the controller and voila.
