After a brief departure onto a couple of other projects, I'm back to complete Project Mego--my 2XL-Google Assistant conversion--and I needed to come up with a way to change the voice from one of the stock Assistant voices to more of a robotic sound. So, I started playing with the Velleman MK171 Voice Changer Kit as a jumping-off point for my own voice modulator. But before I could play with the circuit, I needed to assemble it! ...
One of the first challenges with restoring the 2XL at the heart of Project Mego is repairing and restoring the malfunctioning 8-track player mechanism in his belly. This particular unit has a few broken pieces and a misaligned head, so I'll point out how to correct those minor issues while illustrating a few other interesting features of this "ancient" format.

This segment was cut from the completed project video, but I thought it interesting to have a look inside one of these cheapo voice changer toys that retails for way more than it should. I'm certainly nota531016, but I like to pretend every so often ...
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.   PARTS/TOOLS:  https://www.newark.com

When you're building a project that has multiple modules with different voltage requirements, you may need to build a 5V buck converter. This video walks through the process to build a converter that will take up to 40V input down to 5V at up to 5A, and you can get the schematic as well as the necessary parts in the show notes below!
