I started out as a PCB sub-assembly technician, building robots that shot laser. For concert light shows, so not the Mecha-Godzilla type. It's a fancy title that means I soldered a lot and used an oscilloscope to check my work. I only occasionally dabble in that direction these days. But I will say it was a fascinating time. I think most young people would be surprised at what you can do with analog circuits. It hits home when you make a perfect sine wave by oohing into a microphone. After that, everything you see in an oscilloscope makes sense.
