Forrest Mimms Has Done Much More Than Most Engineers Know (hackaday.com)
szczys writes: If you've been anywhere near the field of electronic design, the name Forrest Mimms (the 3rd) is familiar. He wrote the book on electronics, and is heavily associated with the publications found in every Radio Shack. His entire life has been one prolific science experiment after another, which is why the title of Citizen Scientist fits so perfectly. For example, he invented and has used on a daily basis a device to measure ozone in the atmosphere. It worked so well he discovered and reported a calibration error in NASA's measurements, which are made with satellites.
Last winter, we had need for a replacement electrolytic cap for the driver board on a hall effect motor on a gear drive assembly, since the old one had a bad design. I walked into a RS store (city population around 200,000). I told him I needed a 100uf 25v electrolytic capacitor. The teenage looking (to me) genius looked back at me, like I was talking a different language. "Back in the day" (early 70's), say the same thing in an RS, and they would walk you right to it, probably ask you what you were using it for, discuss circuits, talk about electronics, ham radio (since I am one), SW radio and all sorts of things. Now, the only thing they know are phones, phone cases and the like.
