Portable USB Charger


Instructables has a good tutorial on how to make a cheap usb charger for your portable electronic devices including iPods, PDAs and cellphones. Wouldnt it be great if you could pull out a matchbox size circuit and plug it on your cellphone/iPod when the battery dies and can rejuvenate the life of the battery.
