The bottom LED helix was still unreliable. I did not see any pattern that might indicate a particular piece of faulty hardware, like a loose wire or a malfunctioning controller pin. I added an LED across the power terminals so I could see if power dropped. An RGB LED was closest at hand, and I happened to use the red circuit. No apparent power drops happened while I was watching.

Up to now, I considered the data line at the beginning of the strip to be acceptable. Checking it would have been difficult because it was covered by shrink tube. I cut that away and retouched the data line, which had a few imperfections but looked solid.

As always, a bit of maintenance scare the problems away for a few minutes. Each time I fix this problem, it crops up later, always on the same helix. Fortunately, this problem is a hardware issue, nothing with the software. In the worst case, the lower strip can probably be replaced and tested thoroughly so any broken LEDs can be discarded, and the rest can become spares.
