That sounds like a better way of going about it (but I still need RGB, this is the only one I can find at a decent price.), I'll just sell my ether for a bunch of the w leds. But my question is how well the light will mix when two strips are positioned like this: The RGB strip is ontop and the white strip is on the bottom. Would the colors clash or would they transition well?

When you say dimmer, how much dimmer would you say it is? And I need addressable LEDs because I might as well get an LED bulb if I want uniform color, can't get dynamic colors with an LED bulb.

Yeah I saw those, sk6812, but reviews say they're dimmer than the WS212B. I'm a bit strapped for money so I can't afford 5m of sk6812, but I might look into it.

I plan on using strips as ceiling lights, and saw a strip of white LEDs that I can use to increase the range of colors. How difficult would it be to mix colors if one strip is right below the other?

I already have the Feather M0 lying around with no use, think I'll just use that.

Yeah thats what I'm doing. Looks like its working as intended, but it looks like the strip has a kink so it doesn't light up correctly unless I hold the wires in a certain position.

I mean, I know that. But I don't want to look like an idiot when it turns out I went about it all wrong and fried my strip. It's a sanity check question.

What do you mean? I shorted the motherboard data cable to ground so that the power supply turns on, and I'm using a red wire which I tested for 5v. I haven't cut any cables yet and am using arduino male to male cables to prototype.

I mean it really depends if you are willing to take the risk. Ethereum is moving to casper which will more or less kill mining for it. It's going to be implemented around September 1st I believe. The risk is in mining other coins afterwards or selling your rig and hoping you made enough money mining to pay back the initial cost.

RGB, addressable, and looking at the strip every LED has a resistor.

I isolated a ground and a 5v pin on the main motherboard power cable for my PSU, my cable takes 18A at full brightness and white. One 5v rail outputs 20A the aux outputs 3A, I have no clue how to measure how to measure current or resistance with a multimeter so I don't what the current flow is. Now I'm pretty sure 2A can't hurt, but I just want to be sure I wouldn't fry my strip.

It's not a lot of wasted power, full brightness on white draws 90W, 125W - 90W = 35W. It's not too many wasted watts.

I found some forum post by searching the old computer's name, they say 25A on the 5V rail. So thats 125W.

What I find interesting is that the 5v rail only goes up to 120W. I'll have to SLI 2 PSUs if I want to have all of my ceiling covered.
