Make your own transistors ??? When I was a kid we had to mine copper ore
from the hills with our bare hands, smelt it over a charcoal fire, then draw the wire out
with our teeth...

(who remembers that thread ??? :^)

If you're concentrating on the 'Yourself' then I won't be happy until
you make your own transistors out of germanium crystals. ;-)
