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!
