After studying the Velleman MK171 Voice Changer kit that I assembled in a previous video, I wanted to play around with some elements of the circuit to see if I could customize it. In this video, I'll walk through the circuit schematic and explain how the voice changer works before replicating the design on breadboard, then soldering it to protoboard.
