Hi,
I have a friend who was really really stupid and accidentally soldered his 2m string of LEDs to my, I mean his, power supply with the polarity reversed... (He was having issues with unruly teenagers at the time).
Clearly my really stupid friend believes he likely fried the string, because it didn't work when issuing the test "hyperion-remote" command at the Linux prompt on the pi. I then wondered if it was possible that only some of the ICs were killed. If that were the case, it might be worth chopping up the string and trying various subsections.
Alternatively, it might just be possible that there were enough ESD clamping diodes on all these chips to, together, sink the the 6A (!) available from my P/S. I don't want to jump to conclusions.
Is there a simple way to troubleshoot the string? Any hints?
regards
Doug
