Wear Your LED Television

David Forbes, an electrical engineer by trade, wanted to build something really cool to wear at the Burning Man festival. So he re-purposed a relatively simple flexible circuit board covered with LEDs. He made the first with 30 rows of four LEDs each and then contracted a manufacturer to build 175 more of them. He attached them to an old coat and was able to build a display with a 160 x 120 resolution, which he notes on his blog is exactly half that of an iPod.
Part of the set-up is the same kind of chip used to scale down the images for security cameras, and another is the same type of chip used to control the big LED signs used for advertisements. Adding a small set of circuits that convert the video output of the iPod to the smaller resolution, he was able to put together his wearable display.
The only down side seems to be getting through airports. Forbes also noted that he wasn’t able to create a pair of pants, as the curves over the thighs proved complicated. But he has designed vests.
