Here's a small selection of the 32 amplifier projects built by the Fall '17 Lick-Wilmerding Analog and Digital circuits classes. I've been facilitating this project each fall for a few years now and students continue to amaze me with innovative applications of design, material use, and tool application. All of the amplifiers have a class-D amplifier IC circuit at the heart, to which many students added extra features like analog potentiometers, bluetooth connectivity, and audio responsive lights.
Amity's log amplifier with audio responsive fire lights.
Rafa's bluetooth African continent wall-hanging amplifier
Lucy's phonograph-inspired amplifier with built-in drum machine.
Nevin's koi amplifier with bluetooth and audio-responsive led rings.
Patrick's compact bluetooth-ready amplifier
