I have middling-sized computer speakers and that mp3 made them rattle like they were about to fall apart!

Some time ago I picked up a bunch of 8-foot-pitch organ pipes out of a skip, thinking I might turn them into Paetzold-type recorders by adding toneholes. I soon realized it wasn't that easy - an organ pipe is voiced to play at only the pitch of the full-length pipe, and it also needs far more air than any human-blown instrument. All I can produce is short sharp honks. They might work as drones if I can make a small blower - computer fans?
