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.

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

Samuel's reproduction-radio-turned amplifier with bluetooth and music visualizer.

Brittney and Oscar's solid wood amplifiers.

Ben G's custom-circuit amplifier in the style of a space capsule.

Jasmine's owl amplifier with bluetooth, beak as volume controller and audio-responsive eyes.

Amplifier Designs from Fall 2016 LWHS Analog and Digital Class

Here are a just few of the 30+ amplifier projects built by the Fall '16 Lick-Wilmerding Analog and Digital circuits class. Students mixed all kinds of materials and tools from the CNC cutting to 3D printing to found objects. All of the amplifiers use a class-D amplifier IC circuit at the heart, to which many students added extra features like tweeters, analog potentiometers, bluetooth connectivity, and audio responsive lights.

Great looking and sounding amplified speakers from this semester's Analog and Digital class

**Isaac: with custom milled circuit board, with LED frequency visualizer, and bluetooth**

**Erica: bluetooth enabled and with LED frequency visualizer**

**Kevin: bluetooth enabled and with LED frequency visualizer**

**Ellie: with LED frequency visualizer**

**Chloe: with LED frequency visualizer**

These are just a few of the amazing amplifiers created this semester in the Lick-Wilmerding Analog and Digital class. If only the students would let me take a few home. They REALLY sound good.
