First I believe JR has something in the works for these, but I thought I would share what I have do. I created an Dumb RGB Controller, picture attached. It's really not that hard to figure out how these things work. Doing this really make me appreciate what RJ has done for everyone. It took me several hours designing this thing and a couple of trial and errors, including burning up a couple of 7805's, 1 ST485BN, an ATMEGA328P-PU (Arduino), 2 prototype boards, and a couple of other components. But it's a good feeling when it all comes together.
RJ, RJ's Dad, & all the coop managers my hats off to you for all you do.
Thanks
Scott
