So, this is a pretty ingenious use of spare time. With a vacuum fluorescent display (VFD) from a VCR used as the amplifier, a crafty DIY-er was able to power a pair of headphones. We'll be honest, the wiring specifics are totally irrelevant to our interests, but this sure does look awesome and we might buy one if it was commercially available. The amplified power is, in the maker's own words, "limited," but that's not really the point, and we have a feeling that Thomas Dolby sounded just as scientific (and awesome) as he would through the greatest headphones ever made.
