If you haven’t yet signed up for our Weekend Projects Newsletter, then you’re missing out on some seriously fun, beginner-friendly electronics projects. We’ve already built a Floating Glow Display, and hacked together a USB Webcam Microscope – both in just a few hours over a weekend. For our next project, we’ll be examining the guts of a mono speaker battery-powered toy and modding it into a circuit-bent musical performance device. This project will instruct you on how to add a volume knob and audio output jack to your toy of choice. We’ll be using a keyboard toy in our example, but the rules apply to most mono speaker toys. So, if you want to get the scoop ahead of time, along with additional tips and other project goodies, sign up for the newsletter.
