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?
they are white LEDs i.e. they shine white. the R G B leads are used to trigger them individually, for the running lights and whatnot. so when I bring 12 V to the V lead and GND to e.g. R, all the LEDs marked R (image) light up. when I then short R with G, then all R and G light up, etc.
Interesting, never heard of that arrangement before.
the whole thing (5 meter strip, remote, PSU/controller) cost like $5 total so I'm guessing that's some ingenuity at play, like reusing strips meant for RGB lights and sumsuch
