This is an awesome project.

A kind of tonal instrument that uses a solenoid (electromagnet moving a kind of piston) to tap the surface ow a hard object (in this case a book) to so fast that it generates tones. The concept is beautifully simple, you tap the book 440 times a second and you get middle A (kammertonen) but the results are astonishingly awesome sounding. I want to make one of these !!!1  I reckon ill need a very quick solenoid though, i wonder where to find that.
