When I was in college I worked as an "electronics technician" intern for a few months. We would work through 3-10 page mods to update PCBs from one version to the next. We worked under a scope, and sometimes routed magnet wire all the way across the board, or even thru vias from one side to the other. It was painstaking work; I had a coworker friend who was a true artist. I never got that good at it, but I sometimes miss that kind of work.
