hiya!

I got a cheap LED strip with PSU, controller, and IR remote. I didn’t look at it too much, figured it would be easy to stick it under my kitchen cabinets.

however, this thing blinks and fades and whatnot and I’m supposed to switch it over to constant light by repeatedly pressing the remote, which a) works shitty and also b) don’t wanna do that. I just want to plug it into power and it lights up and that’s the end of our interaction.

so, I opened up the PSU/controller and I’d like to locate the spots that give me +12V and GND and I can bypass the whole blinky fadey mess.

it’s a single-sided PCB. the top three wires on the right are for the IR receiver, ignore 'em. the bottom 4 are R, G, B, 12 V, respectively. I’m shorting RGB as it’s a white-only strip.

can you hazard a guess where I’m most likely to succeed?

    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 :/
