This brave fellow plans on wearing this thing at Burning Man, which you may know is in the desert. I can’t think of anything I’d like to be wearing less than a full-on labcoat loaded down with PCBs, batteries, and so on.
The TV plays NTSC video and it’s 160×120 (for smooth resizing of 320×240). The PCB is flexible, so no need to worry about breaking it when you’re twiddling with the knobs on your shoulders. The batteries last about an hour, which is probably longer than it will take this poor guy to die of heat exhaustion out there with this thing on.
