RSSNerdkits shares their process for designing a big LED VU meter, and repurposing piezo buzzers as microphones in the process. I did notice it covers in detail one topic that is surprisingly absent from most electronics project vids - Math! Great to see real live equations put to work in a design from the ground up - shed some much needed light on this process for the uninitiated.
