The roof of the Spinner has six domes, each fitted with flashing leds. There are also smaller lights but I'm tackling the round domes now.
I got the system to work, beautiful flashing pattern, then the board shorted and killed current to two leds. I couldn't figure out where the problem was, so I rewired the whole thing. Found the fault when ripping the wires off, it would have been very simple to fix. It was just a stray strand, easy to remove with a toothpick or such. Damn!
Rewiring the board went well, I figured out a better way to solder it and it now has a solid clean wiring. Checking the bdriver, electric current goes to all the right places but, alas, two leds are dead. They are not not the same two that were dead earlier and the problem is not with the board.
Ten hours straight with the soldering iron today, and I cannot troubleshoot the fault. Putting the soldering iron down for today, I got four lights, two blanks and an urge to smash the whole thing to million pieces with a hammer.
You know how it is.
