One of the features of a channel page on YouTube is a trailer video. It's a chance to introduce people who aren't familiar with your channel. Subscribers won't see it, only non-subscribers. To help explain AddOhms, we've created an introduction video. This replaces the first one where I introduced AddOhms from my lab.
Since AddOhms is more about the drawing than a bald engineer on camera, I thought it made since to create an AddOhms-style introduction.
