Introduction: Super USB Charger, and 12V Power Supply
This is super super simple power supply that will give you a high current 5v supply you can charge a zillion devices at once with, and a decent 12v power supply. No soldering required.
Step 1: Mount Screw Terminal Strip, Cut Wires, Separate Wires, Trim Wires, Strip Wires, Attach to Terminal.
First, you need a PC Power Supply (aka, ATX Power Supply). And order some of these, they are an AWESOME value: http://www.amazon.com/uxcell%C2%AE-Position-Screw-... They cost about $1.04 a piece (5 for $5, like Arby's sandwhiches used to be). My Dad gave me 4, and I used 3 of them in a few weeks they are so handy. So if you can afford it, go ahead and buy a dozen :)
Attach the terminal block someplace on the power supply. I like the cord hanging down, and the terminal strip facing me. You could glue it on, use velcro, or use self drilling screws to attach it, whatever, doesn't really matter. (If you do use self drilling screws make sure you aren't drilling into the pcb inside the power supply).
Cut ALL the connectors off of the end of the wires. Cut it close to the connectors, trust me, you'll probably NEVER use those connectors.
Separate all the wires and group them by color. All you care about are the Green, Black, Orange, Red Yellow. Group the Green wire with the Black wires.
Trim the wires to the same length as the rest of the ones of the same color.
Strip the ends of the wires. Twist the same colors together (Green goes with Black). And clamp them down in the screw terminals. The Power Supply turns on when the Green wire is attached to the ground (black) wires.
Viola! You are done! It's that easy.
To touch it up, you can cut the other wires short, and tape the ends off. Or use zip-ties to keep it short.
Black is ground. Yellow is 12V, Red is 5V, Orange is 3.3V. You can easily cut a usb cable and attach it to the 5v supply to charge devices. I used the 12V supply to hookup a car audio amp and speakers with a sub-woofer to my computer...
