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. greg
