Electronic Voices

This class aims to demystify the invisible physical phenomenon that we process as sound. We will follow the mechanical and electrical pioneers of the 19th and 20th century as they spent sleepless nights trying to capture the minute fluctuations in air pressure that our brain effortlessly decodes as sound

This class will explain and re-create some of the experiments of the early sound recording pioneers and then go on to cover the history and techniques of sound manipulation through the acoustical, electrical, and digital eras.

In this class we will learn some the basics of early sound recording and reproduction and learn to build a makeshift phonograph using mechanical amplification. We will then move on to discuss electronics and electromagnetism and how they relate to recording and amplifying sound. We will eventually build a working speaker out of a post-it note, a wire, and a magnet.

This class is also available as a three-session course in which we build a solid-state amplifier in a cigar box:

David Sheinkopf has taught in the NY school system for 10 years and has spent the last 5 of those years developing a curriculum for teaching analog and digital electronics to high school students in order to prepare them for life in an increasingly-electrified world. Before teaching, Sheinkopf worked in a garage that specialized in vintage european sports cars making him as comfortable with a box wrench as he is with a soldering iron. His electronic work has been used by artists at the Brooklyn Museum, the Red Hook Criterium, and in various gallery shows. His mechanical work can also be seen riding around New York on one of the many bikes he has serviced and sold at his underground bike shop in Red Hook, Brooklyn.
