I actually need some advice from anyone who has been here before me. I was wiring up a new prop today and have 20 pixels that are 5v and 4 that are 12v, so I decided to use a buck converter and run the prop on 12v. Now comes the problem, after spending hours wiring it up and getting interrupted every 5 minutes, i hooked it all up and turned on the power befor realising I hadn't adjusted the output of the converter. long story short, I heaped 12v onto the 5v pixels and now they don't work. What is the best way to try and work out which pixels do and don't work. It was an absolute pain to mount the pixels in the first place, so i don't want to do the whole lot again if at all possible.
