Make Your Own USB Power Supply

Need a cheap USB power supply to charge or power your PSP, iPod or any other USB device?

A forum member at Hacked Gadgets called Reverend Jones has a way to make your own USB power supply from an old plug in power supply To convert this old power supply into a USB power supply he says to first acquire a regulated 5 vdc wallwart (old power supply) rated at 500ma or higher (he used one from an IoMega Zip drive) and then added:

  • 330 ohm 1/4 watt resister

  • 10k ohm 1/4 watt resister

  • 3mm LED (red, green or yellow)

  • USB-A jack, female
Here's a shot of the original power supply
This is the power supply with all of the parts exposed
Here's the final product. Looks nice and it's useful.

What a great way to re-use old computer parts instead of tossing them in the landfill! Read the entire how-to over at Hacked Gadgets Forums
