[sdiy] pot values

[Colin Raffel]

A "Kludge" for this I have commonly used is using the H11F3 as a  
variable resistor, though it may be difficult to get 1meg out of it.   
You would need to breadboard and play around.  I have "converted  
resistances" as such though.  The principle is basically that you use  
the pot to control the current going to the LED from your power  
supply, then use pins 4 and 6 as the pins of your new resistance.
