Peridically I get the feeling that radio ... is getting far too hard
to do - you need 99%+ pure Ge/Si ... and huge factories and $00000000.

One the other hand:
   You can make resistors out of pencil leads, capacitors and
inductors are easy, headphones are possible (not easy) and you can
use Galena (lead sulphide I think for a diode), but what about things
with GAIN.

I've had this dream of making a triode in a peanut butter jar (a
small strong one :=) ...


Has anyone out there ever tried to make something like this or any
homemade semiconductors ....

And how about batteries with household chemicals (ie not sulphuric)

I can't be the only one who has these thoughts ...

Cheers
Giovanni
