Speaking of which, has anyone tried to recreate Nyle Steiner's famous  
experiments with Zinc used as a negative resistance oscillator?

I tried once, but only got it to oscillate a few times.  It was very  
picky...   but no one will ever stop manufacturing it!!!

He mentioned that we was never able to create gain using his  
techniques but I dream of being able to do that someday.
