Chuck shared an antique piece of engineering project his father made on the Adafruit Forums:
I was looking at a home made electric motor made by my father made out of wood, metal and wire.
Where did hobbyists get their electronic parts before 1921 or 1892?
The middle is actually a nail if you had not noticed.
I always looked at the parts as a piece of junk but the engineering is more important than looks.
I wondered where people got their parts before Radio Shack, General Electric and RCA.
