[sdiy] Concentric pots

[Toby Paddock]

Not quite, but somewhat related,  in 
Jan 20 2003 Electronic Design there 
is a "single pot controlled multi 
digital pot with another digital 
pot for servo control sort of circuit" 
that might be good for something. Maybe.

Title: Use rotary potentiometer to 
drive solid-state volume control.

Oh... I just noticed the pot's resolution 
is only 100 steps.
