Recycled Sound

"Recycled Sound" is an amplified speaker made with recycled objects: a lemon tin, old radio knobs, and a metal shot glass. The shot glass is the speaker, suspended by rubber bands with a hole drilled in its center. A piece of copper pipe was fitted in the hole and  wrapped with magnetic wire. The circuit inside is made with an LM386N. I love this project because it is the bare bones of how sound is amplified with magnets.
