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 ...
