Inspired by the Ablenet Big Mack, this DIY version uses the Adafruit Circuit Playground to play sound, light up neopixels and even function as a USB mouse clicker. The code was written by Limor Fried in Circuit Python, so it’s easy to build on top of using Adafruit’s libraries. A PAM8302 audio amplifier and a 3W speaker provide decent volume and its adjustable with a potentiometer. Check out the guide for full list of build materials, source files and code!
