Chances are that if you’re reading this you’re probably breathing as well. Not only that you probably have a plethora of USB devices, and some of them might need charging. A guy that goes by the name of [jmengel] has designed a device that turns your everyday breathing into a USB charger using scavenged parts from a CD-ROM drive, a simple circuit and some rubber bands. Of course he says that, “this project requires a wide range of "maker" skills, such as PCB board manufacture, dismantling of electronics, cutting and drilling plastics, mixing epoxy, designing a gear train, kludging together a bunch of parts, bending paper clips, and risking the well being of your ever so expensive phone, camera, or PDA.” If that seems easy enough for you head over to this link for the break down on how to build your own: http://www.instructables.com/id/Breath-powered-USB-charger/
