The other day while in Senior Daydreaming Mode I tried to remember how I got my first interest in electronics.
I recall my grandfather encouraging me as I built various adaptations of crystal set radios. Remember those? Hand wound coils around toilet paper tubes. Galena crystals tickled by a "cat's whisker" wire. A water pipe for ground, mattress springs for the antenna. On a good night with enough tweaking you could pick up two or three AM radio stations in the Chicago area. Headphones, of course. Don't sneeze - if you did you'd have to re-tune. It was fun, it was magic.
Anyone else remember those? I'm guessing there are a few geezers here who do.
