Powering the Raspberry Pi.

Wanted to make a Raspberry Pi where I could have several units in one case. Putting several power supplies in one box seemed like a mess. Instead I decided to use an old "AT" (not atx) power supply. I did not want to cut up the cable from the power supply. I looked for a dead motherboard in the junk box. There was one! Now, had to get out the old heat fun (used for paint removal. Most "AT" motherboards are attached to the pc like this:
But if you have a dead motherboard it will not need the Power supply header anymore. So the mother board looked like this:
Now we want to add heat to the back side of the motherboard to release the header. Be careful as it is HOT. Solder could come flying and burn you. Wear protective clothing. Then once the header is free and cooled, it should look like this:
Ahh, free parts!! So now I can use the header with the Raspberrty Pi once I have soldered some wires to the header. PC Power supply must be turned off and disconnected from wall power while soldering. I.e solder the header disconnected from anything. Hint: Be sure to also use a glue gun to seal the solder connections so nothing can get shorted out.
You will need a pinout listing for that particular power supply you want to use. (Varying power supplies are not all the same when it comes to the pinouts!!)
This power supply only uses two of the three connectors. But what we need is a +5v (usually red) and a ground (usually black) to power the Raspberry Pi. So we could eventually power up to four units. The disk drive cables could aso be used, but we let them be for drives we could attach to the Raspberry Pi.
