Next year I would like to do a 180 degree pixel tree. For storage reasons I'm probably going to do an 8' one. The strips I'm looking at are 150 LED with 50 nodes per 5M, 5VDC. So all of the RGB LED's are grouped in three's. I plan on cutting 6 5M strips in half so the tree would be 12x25 pixel nodes for a total of 300 pixel nodes (channels). I will be using a sandevices E682.
My question is wiring. since the WHOLE TREE is less than one universe, I was curious if I could run 150 pixel nodes (Tree left 6x25) off of one output of the E682, injecting power every 50 pixels and than doing the same on the (Tree right 6x25). In theory I could run the whole tree off of 1 output since it's only 300 channels. I understand there would be more wiring with all the power injection.
Seems like such a waste to take up 12 outputs on the e682 when I can do it off just one or two outputs. That would free the other 14-15 outputs for me to add other pixels elsewhere in my display.
If the E682 supports up to 2040 pixel nodes in unicast and I'm using 300 channels for the tree that leaves me 1740 unused channels. If I spread the tree across 12 outputs, that only leaves me 4 outputs on the E682 for the other 1740 channels.
So my question is: What is the advantage/disadvantage to running it off one or two outputs as opposed to 25 nodes each on their own individual output?
Just want to drive as many pixels as I can off of the E682.
