The best laid plans of men and mice often go awry. I am hooking up half of arches, poles, fans, and candy canes. 128 pixels on each, all 12 volt. Had planned on going out of the same section of a 682. I was thinking, well these are all 2811's , no problems. Well hooked them all up today and they are 3 different colors, i forgot the although they are all 2811's, 2 are strips, 1 is nodes and 1 is modules, that is how you get 3 different colors. On to plan B for that dilemma. 2nd thing, the arches when hooked up, sort of strobe every few seconds, they control fine, but all I can do is describe as strobe every few seconds. I am using power injection on all props. When i disconnect the ground going to the power supply they don't strobe anymore. I tried a different power supply, same results. Anyone care to explain to me what might be going on there? Its to cold outside today to do much troubleshooting.
