Lego Brick Audio Analyzer

Posted on April 23, 2023 by Mark Donners

This Analyzer is based on my Analog analyzer but this time, I put it in a housing made of lego bricks.
The audio analysis is done with opamp band filters, the old fashion way….The front end is done by using a ESP32 to create patterns to be displayed with pixel leds.
This is a demo only. If you want to build your one, please visit the element 14 community for all details here:
