     Almost the same here, my dad took a night course in 
electronics and another in photography. Somehow I am the one 
who took up both. We built a crystal radio, real breadboard 
with hand wound coils. The photography started with a Kodak 
darkroom in a box he brought home. So Moi set this up in the 
basement and developed and printed a roll of film from a 
Brownie. I got bit hard by both.
