Homebrew USB Charger

Homebrew USB Charger

There are plenty of examples on the net on how to build your own usb charger, but since we didn’t have any on our site I figured I’d share it with you.  I found an old wall wort in my junk drawer that I couldn’t remember what it went to, so I figured it would be great to put it to a good use as a USB device charger. Because I didn’t have a clue what the maximum current draw requirements were for a USB device, I found the requirements on USB.org’s website.
