You will need:
1x Computer Power Supply (PSU), Anything above 250w should be fine, i have used a 350w one as thats what i have lying around.
some screws about 30mm long.
a piece of flat wood. Roughly 400x400mm
Tools:
Side cutters.
Screw driver.
insulation Tape or Heat shrink if you want to make it look nicer.
Soldering Iron.
Its very simple, but if you feel unsure best to ask someone who is a little computer savvy. Playing with electricity IS NOT safe, if your not 100% confident, don't attempt it. I don't want to get blamed for someone frying themselves. In saying that DC power is pretty safe but still, you never know...
Ok ill do my best to explain it, any questions just ask.
Step 1: Grab the PSU. Take the large plug that normally plugs into the mother board, cut the green wire, and cut one of the black wires, Join these two wires together, solder and tape so no wire is exposed.
Step 2: Cut off one of the molex plugs for the Hard drive. The yellow wire (positive) and the black wire (negative), are the ones your going to use. the red wire and the other black wire are not needed, so cut them short and tape them up so no wire is exposed, and they cannot touch each other.
Step 3: Screw the PSU to the piece of wood(to do this you will need to take it apart), and hide the excess wiring inside the PSU, you only need the yellow and black wires talked about in step 2. And reassembled it.
Step 4: Screw 2 screws into the wood about 50mm apart, strip the yellow and black wires. Then wind the yellow wire around 1 screw and the black wire around the other screw. Solder these wires as to stop them pulling off.
After tiding up the wires. Securing the cable to the board, and cable tying it all together as to stop it getting pulled apart, it's done. Took me about 35 minuets. Shouldn't take a newbie more than 1 hour I reckon.
Generally most PSU's have more than 1 hard drive drive cable, so you could make more than one terminal to charge off. although I have run 2 chargers off one cable and it works fine. On my set up I have run 3 terminals as I have 3 chargers plugged in normally.
Now i know it would be better if i had photographed this in every step, but as this is a bit of an after thought i didn't. I am more than happy to help someone make one if they are a bit unsure. I am in Auckland, and you will need to drive to Pakuranga. Pm me if you need help. I am also happy to make one for someone for the price of parts and freight if i have to send it away.
:D
