If I could redo this video with a head-mounted camera, I would! But I won't. This took ages to edit. Sorry for the bad camera focus and my body being in the way for much of this. I'm investigating better ways to record myself doing work that involves my hands.

Always have the receiver unplugged when working on it. I am not responsible for any damage or personal injury. Perform this work at your own risk.
