[sdiy] wacky pneumatic controller idea

[Michael Ruberto]

back in the day, gas stations used to have a bell that rang when a car 
pulled into the lot. the mechanism was a simple one, just a piece of capped 
off hose which connected to an air pressure switch. using a modern 
subminiture pressure sensor and some surgical tubing it just might be 
possible to build a pneumatic controller for synth use. seems like a good 
idea, but then again it's very late and I have spent way too many hours in 
front of the PCB designer screen.
