[sdiy] Zener clipping Was : ...that 1K resistor on the output

[Paul Perry]

That "zener in a ring" goes back to analog computing days - I think Bob 
Pease claims to have independently invented it.
I suspect there may be some interesting applications for it, yet to come.
And yes, all great ideas are pretty obvious - but only after someone 
discovers them ;-D
