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?
is it fluctuating, because there is no load attached?
the fading as well as the color changing should be controlled by the three transistors next to the cables. the connections i highlighted are before those transistors, so there should be no fading at that point.
if it’s still fluctuating, if you have a load attached, i’d just go with some cheap 12v psu and call it a day.
