Making a bench power supply out of an ATX computer power supply is a fairly common practice among DIY types. These power supplies are plentiful. You can find them all over the place, such as trash dumpsters and likely even somewhere in your own house. A quick modification, and the computer power supply can give you a decent 12v, 5v, and 3.3v.
Many people stop at simply making the power supply capable of initializing without the presence of the computer's motherboard. Instructables user jedii72 didn't want to stop there, though. He really wanted to make something a little more portable and feature-rich so that he could carry it between his two most common work areas.
The idea he came up with was the AT-ATX, a power providing Star Wars AT-AT walker. He would mount the power supply inside this retro toy and have a nostalgia-rich carrying case for his power. A simple face plate with quick-release ports would be easy enough to make and would get the job done. Why stop there though?
In addition to being a simple power supply, this AT-ATX also packs a Voltmeter and a USB hub for charging those mobile devices. A slick black paint job really ties everything together quite nicely.
