New technology to be discussed

thanks Aron. some good ideas to use

i'll keep looking and checking up. i have lots of questions like don't know about that network i guess reverse bias the diode for variable resistance
How would a reverse bias diode variable resistance work with an inductor to do this?

I guess use the diode as a vactor?
I'm not sure u tell me

This ain't funny...  it's a scary good imitation.

Post #4 is another sort of "joke" that many here will not get.  Andrew, you rascal!!  You had me going there. 

I got a bit concerned myself!
