Back in the days when I owned an Acorn Electron, Acornsoft View and a dot matrix printer I often believed, during lengthy and hypnotic printing sessions, that my clunky old printer could - with a little ingenious programming - be used as a drum machine. Perhaps it could even make beautiful music. I was wrong.
 
Nearly twenty years later (last summer, actually), Epistaxis Time tried it for real in a Resonance FM broadcast by building an "instrument of punishment" called the Dot Matrix Guitar. Host Dan Wilson said "It's a raspy, nasty noise. I hope it agitates you." It does.

Resonance FM is ace. One recent show was 8-Bit Adventures - 30 minutes of bleeps from the world's best 8-bit musicians. The radio station is based in London but you can listen to it in streaming MP3 format from anywhere in the world by the power of Greyskullthe Internet. Unfortunately they're fairly strapped for cash, so join in the fundraising if you can. Even if the shows I've mentioned aren't your fancy, it's brilliant to find a radio station with the freedom to commission and broadcast stuff like this.
