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?

    well, I sorted it. just like @fuzzy_feeling@programming.dev and others guessed, that was the correct spot to get the power from. the issue with the fluctuating voltage was due to my shitty multimeter, checked it with another one and boom, 12 V. well, no boom, that’s just an expression.

      Thanks for the closure, glad you got it sorted! You might just need to change the batteries on your multimeter to get it back to normal.
