Just finished 24 x 50 pixel mini trees. 24V power supply 24V/12V x 5V Buck converters. Bench tested each one as it was completed then added it to others to make a daisy chain of 6. Left them running on xLights test cycle and completed the next 6, same deal - bench test then put on a 2nd output up to 6 until all 24 done on 4 outputs. Moved them 3m across the shed to setup for full run and a Woopeee Video BUT Now random between RED BLUE GREEN WHITE. Sometimes all three cycle then one gets randomly missed or will not go at all. Made a test rig with 300mm lead to eliminate the 3m leads they are built with and exactly the same pattern. Changed the Pixlite 4, no change to result. Tried 12V supply - no change Tried connecting 5V and no Buck Converter - no change. Changed cat 5 cable - No change Rebooted Lap Top - no change. Only thing NOT changed is the LAP TOP ... maybe the dog knocking it off the bench may have done some internal damage :'( Time for a beer but even that won't work as I don't drink.
