[sdiy] Knobs with LEDs

[Paul Perry]

Yes, but..
it's a rotary controller that REALLY needs something, and if you want to 
indicate an ordinary pot with leds, you can just make the pot a dual and use 
the second pot to generate a control voltage that drives a multi-led level 
indicator. (If National Semi still make them..)

I guess the intent is only to provide indication over the approximately 300 
degree range of a rotary
potentiometer.
