The Raspberry Pi is a wonderful little single board computer that is based on the arm architecture. You can use it for everything from a media streamer, as a server, and all kinds of computer applications. It has one shortcoming at least for now that is a small challenge. It does not use a standard power supply input. You can dissect a walwart and make a special adapter. What I would like to do is to make a generic interface that can be reused if the walwart ever goes bad.

Get a professional to help even if you are the least bit unsure.Do not solderor touch anthing while connect5ed to power supply.
Step 1: What Is Needed:
Power adapter via a barrel connector that outputs 5 volts DC with enough current as your Raspberry Pi requires.. (I used the one from my Nslu2 ( 2 amp output) for testing. (Do not use any other boltage (i.e. 12 volts) or you will damage your equipment.
Micro (not mini) usb cable.
Female power plug that will hold the male end of the power supply
We will use the packaging for the female power plug as a temporary case.
