Comment on bypass controller on a cheap LED strip
dingdongitsabear@lemmy.ml 3 days agomeasuring difference between ground plane and the various points didn’t give me a stable voltage. the black thingy leading to the 12 V line is a SS210 (search says that’s a schottky diode) and on its output the mentioned fluctuation is happening. on its input there’s some very low voltage happening, like sub 1V (got a shitty multimeter).
if I’m understanding this correctly, then this thing boosts the voltage but the fluctuation is happening somewhere else. in other words, there is no 12 V source on this board. or?

Maybe you can trace that low voltage fluctuating line back to one of the ICs?, and work put how to disable that IC?
Or, use the remote to output solid white, and find the voltage on that line, and then try find that voltage somewhere else and short the two?
I’m running out of ideas though, I suspect buying a cheapo power supply might be easier :/

that’s a solid line, I’m gonna try that. hopefully won’t burn nothing of value. thanks
