I learned how to solder the little resistors, and that requires the microscope.
They still look small. The iron looks like a bat and the tweezers a claw, and
the little resistor looks like a speck.

I would need a stronger scope to read any lettering on it.
Some larger parts have little two letter codes on them and I don't even want to know what they mean.
