Can't seem to figure this one out.
I am running some 12vdc pixels, three LED's per pixel and I cannot get the power injection to not mess up the display. The pixels are ws2812's, three wire. Some are rectangular pixels some are 5m strips. I have the common pigtails that holiday coro/Ray wu sells along with the T's for power injection.
When I run power to the middle of a string the pixels going out from that point go screwy, flickering and staying on all the time. After about 30 pixels the rest of the lights will work well. If I run it to the end of the string it seems to work fine as long as the string is very long, like 2+ full 5m strips connected together. When I run these through the 3 bulb rectangular pixels the voltage drops out after about 50 pixels and the remaining lights stay off. On those if I inject at the end the entire string turns off. I can get them to work by cutting the power that is going into the last 30 pixels and leaving only power going into the end but it seems as though I occasionally get a bulb stuck on or something strange.
I have tried injecting power with different 12 v converters, the same on that is running the controller, short runs of wire, long runs. I seem to get the same results with them all.
I have a bunch of 5v strips and I've never had any problem injecting power to them, the 12v just don't seem to want to cooperate.
