The Hang is a unique and beautiful sounding instrument developed in Switzerland in 2000. They are extremely rare and hard to get a hold of.  Here’s how to build a $27 version of one using a propane tank.  Original instructions here.

I recently discovered Josephson microphones.  These Santa Cruz-based engineers are doing groundbreaking design work. Pictured here is the anechoic chamber used for testing the sensitivity of each mic.  Click through the photo for a link to a fascinating Wired article on their process.

Exciting new research striving to reinvent microphones based on the mammalian hearing system.
 ”A microphone is a device that converts mechanical waves into electrical ones. It consists of a diaphragm attached to a coil which sits in a magnetic field. When a sound wave hits the diaphragm, it moves the coil, generating a current. This signal is then amplified by conventional electronic methods.
But an interesting question is why the amplification has to be done electronically. Why not mechanically?”

There’s an exciting new school opening up in San Francisco this Fall called Brightworks.  I’m designing a sound ceremony for the opening of their brand new space next Friday, April 29th.  Doors are at 4pm, ceremony starts at 5:30pm.

I’ve been working on building a new glass chladni plate. The other day I was drilling a hole in the center of a sheet of glass with a small carbide bit when it unexpectedly shattered. If you look closely, you can see that the shards of glass are not only continuing to fall apart, they are actually popping apart with force! Any ideas about why this is happening?
