So I realize that after viewing multiple instructables and creating multiple projects I was using up batteries like crazy. I decided to wire up my own power supply after doing a quick search. My power is capable of your standard voltage of 3.3, 5, and 12. This setup and process that it took to create this project was about 2 hours including the package design. The Package design was simply made out of sheets of plastics I had lying around. It has a blue LED to indicate that it has been turn on, and a red and yellow LED to show the flow of power.
You can find 2 videos at the end of this project that shows me testing out the power box.

This was an important project to me because it allows me to save countless amounts of batteries in the never future, and this is Important to a kid like me going to college because money wont be easy to come by. Not only can you power possibly 3 devices with a little modification but you will end up creating a greener and more cleaner world. Sure its still using electricity but at least it is not using harmful batteries that are hard to get rid of.

Also a key note for my project i did not include a 10 watt resistor.

Materials
Banana jacks
12V switch
300 ohm resistor
ATX connector (purchased or scavanged)
2 leds
Some type of enclosure

Step 1: Open up Power box

What you have to do here is bundle up the same wires with each other and follow the chart below for guidelines of which color mean and what do they do. The most important wires will be the Black, Red, Orange, Green, and Yellow. Gray and purple are used to create a stand by and power on light. I would follow the description next to certain colors on help connecting them.
Good instructable...any idea how to mod it to get 24vs too?

I dont think so most power sources dont go up to 24 volts.
