Rubber Chicken Subwoofer

About the project

I thought it would be funny to listen to music via Rubber Chicken, thus this Bluetooth Rubber Chicken Subwoofer was born.

Story

I had the idea to make a funny Bluetooth speaker that makes noise by physically squeezing those squawking rubber chickens. I have a YouTube channel where I make these kinds of projects, linked below you can find the build and demonstration videos!

The device works by using an incoming audio signal via salvaged bluetooth earbuds. Then splitting the signal into 7 different channels using an Audio Analyzer (DFRobot brand), those signals get sent an Arduino Mega which then triggers a 12V solenoid. The solenoid is triggered by a circuit using a 30N06L MOSFET.

The enclosure used to hold the chicken was just a simple Sputnik inspired holder mocked up in Solidworks and 3D Printed. The print combined with some strategically placed/hot-glued popsicle sticks were enough to hold the chicken and solenoid in place.
