I have E682 controller (6 universes = around 1000 pixels) because of simplicity to connect 16 pixel powered strings to each connector. To connect all 32 strings it would require another E682 . Assembled E682 cost $188 with US shipping. The price for the mega tree controllers would be $372. I could also use the ECG-P12 (12 universes = 2040 pixels, cost $185) and figure out the power injection. The controller cost would be better than for 2 E682. Because each universe can only have 3 strings (150 pixels together using 50 pixel strings). Which means I could wire the string up, down and up again per each universe on the tree. The another strings (universe) would have to start from the top of course. This option appears more economical but it requires extra wiring, power injection but it would utilize the controller capacity better and it would be also cheaper. My question is: Could I use 3 strings on each universe and still be able to use the nutcracker software to handle the mega tree sequencing correctly? Does anybody uses ECG-P12 to control whole mega tree? Thank you for your suggestions.
