As part of a larger project, I built an RGB LED strip switch board that can be controlled by a Raspberry Pi. I'm not much of an electrical engineer, so don't judge my awful schematics and soldering.
I looked through a ton of online articles some were hit or miss. I based my project off of David Ordnung's post.
I used a piece of perfboard without any solder spots. I don't recommend using these at all. They're incredibly difficult to worth with and you end up with a bunch of loose components. That said, it's what I had and it did the job.
Soldering everything together with wires is also really delicate work and requires decent soldering skills. It can e done haphazardly like I did, but it will end up with melted insulation and possibly more shorts than you wanted. I'd still recommend getting a perfboard with solder pads.
I initially tried just using the adhesive on the LED strip, but that was woefully inadequite. I was mounting to the back side of monitors and they fell off almost instantly. So I went searching my local hardware store and found some drywall corners. They're intended to make a clean seam in the corner of the room where drywall comes together. Easy to cut to size and rigid enough for my purposes.
And I mounted the newly trimmed switch board directly to the drywall corner.
I then used double sided tape to adhere it to the back of the monitor.
Looks pretty good.
NOTE: I hope to update this more with better instructions in the near future, but wanted to get this up.
