I did the math, and first I tried to derive some equations to calculate the component values directly, but I haven't messed with differential equations since last year... so that ended up as page full of chicken scratch.

so I decided just to loop a million times and make little adjustments, works like a charm.

If anybody wants to try it out. here's the link.

of course, you have to have the visual Basic Runtime dll's...
