Oh, I love electronic gadgets too. I think I could have enjoyed doing what you do. The closest I come to doing what you do is working on computer hardware. I have built/rebuilt hundreds of computers. I do more work with software though.
I work in food plants. The regulatory rules require them to wash the crap out of everything almost every day with caustic foam and high pressure washing. It ruins almost everything as a result of the moisture and temperature. Wiring rots, connectors turn green, PLC’s get soaked, RTD’s turn black, and so on. Guaranteed employment.
