Um, I did a google search and couldn't see anything on turning a resistive load (which is what I am guessing a variable resistor is) to a capacitive load. Could you offer any advice here? I found an article that talk about using Pots on the Mega8 and they look like they are pretty raw? Thanks for the heads up! Stuart Whelan.
