A brain teaser for members...
Can you identify this common electronic device?
I am being ever so slighty cruel...
so a hint or two is only fair....
1> Older versions were much bigger
2> Was more common thirty years ago, but making a comeback!
3> 2nd image is of same device type, but different construction.
4> The images are of modern versions constructed at the nano scale
5> Theory of operation was state of the art fifty years ago
If you do know , please don't spoil it for the others
