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?”
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?
