The common-or-garden piezo factor is commonly used as little greater than a buzzer in lots of tasks. Nonetheless, you are able to do extra with them, as [Something Physical] demonstrates with their nifty piezo noise field. Try the video (and audio) under.
The development is straightforward sufficient, engaging in its personal means, with a rugged junk-assembly form of type. The video begins out by demonstrating using a piezo factor attached as a easy contact microphone, earlier than creating it into one thing extra eclectic.
The fundamental idea: Mount the piezo factor to a metallic field fitted with quite a lot of oddball implements. What sort of implements? Spiralled copper wires, a spring, and elements of a whisk. When struck, plucked, or twanged, they conduct vibrations by the field, the microphone picks them up, and the field passes the sound on to different audio gear.
It may appear frivolous, nevertheless it’s acquired some actual worth for avant-garde musical experimentation. Specifically, if you happen to’re in search of bizarre indicators to feed into your results rack or modular synth setup, this can be a excellent place to start out.
We’ve seen piezos put to different percussive makes use of earlier than, too.
