"Sure, viewable eyewear (such as that made by Vuzix) might look like fun, but even with the display balancing on the bridge of your nose you need to find a place to wear that video source. What our man Pascal Brisset did is design a Linux system around a Gumstix Overo Fire computer-on-module, a Vuzix VR920 head-mounted stereoscopic 640 x 480 display (complete with 3D tilt sensor and 3D magnetic compass), WiFi, and Bluetooth modules -- the whole shebang resides in (and on) the eyewear, just the thing for secure telepresence and augmented reality applications (or just extra-private web browsing). And he did it all for under a grand. In order to implement his design, Pascal had to design and custom manufacture a digital-to-analog video converter board using direct-to-PCB inkjet printing. As Hack A Day notes, one can easily question the wisdom of \"a pair of microwave transceivers and a LiPo battery strapped directly over one's eyes and brain,\" but that's the price of progress, right?
