Hello,
You can make a point contact diode with a small plate of steel or iron that has rusted and a metal needle. The point of the needle has to come barely into contact with the rust on the metal plate.
Now the question is, could we make a transistor using two needles with points closely spaced?
I've made a point contact diode but just thought about making the transistor after someone asked a question about transistors on another site.
I did not try it nor look into if it would work at all. It would have to show some amplification.
This is more for the hobby value of course.
