I posted this as a comment to an older thread I started, but it probly got lost in the shuffle. Short version is that I was seeing flashes in my strip after a couple hundred LEDs. I took the strip down off the roof, tested for power issues, looked for bad joints, cut out a handful of LEDs and what I’ve got now is this:
SOMETHING is bad SOMEWHERE. When I pinch or twist areas near where I start to see flashing and randomness, it changes and data seems to get past the hump, but only briefly. Is there something I should be visually looking for, or am I stuck guessing and cutting out LEDs until they work?
Generally speaking, I can get one lit pixel to travel down the line pretty good, but when I run them all, like in the generic demo, I start seeing this mess.
