AMPLIFIER DESIGNS FROM FALL 2017 LWHS ANALOG AND DIGITAL CLASS

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.
