Hi, guys first post on your forum and not totally sure where to put this post because it deals with pixels, controllers, and power supplies but here goes. I have a P12S controller with a 5volt power supply and ws2811 5v pixels. I would like to do this, make a 18 strand mega tree using 6 universes so each universe would have 3- 50 node ws2811 5v pixel strands connected together which would go up the tree back down and then back up again. I believe each 50 pixels would need to have power injected to it so does this mean I have to go to the top of the tree with a long run of cable to inject power between strings 1 and 2 or is there something I'm missing ?
