Breath powered USB charger

via makezine

Jmengel made a GREAT USB charger, powered by breathing!

He writes –

Are you breathing? Do you have a gadget that can be charged via a USB port? Well if you answered yes to both, then you are in luck. This instructable shows how to make a device that will charge your USB-capable devices while you do what you do best. Breathe. Using some parts scavenged from an old CD-ROM drive, a simple electronic circuit, and a few rubber bands you will soon be huffing and puffing your way to fully-charged pseudo-useful electronic gadget nirvana.
