How to make a VU meter

Learn how to make a VU meter with a hands-on Keystone Science build. This is for curious builders who want the experiment, the intuition, and the little details that make the idea click. Hey, I'm Nate Stone. In this video, we dig into a VU meter through a real Keystone Science project. The goal is not just to show the finished thing. It is to make the idea feel understandable, buildable, and a little more alive than it looked before. I walk through the setup, the useful parts of the build, and the science hiding inside the result. If you are here for parts, buy links, diagrams, follow-up notes, or a cleaner project writeup, use the project page below.
