[sdiy] Vactrol/photocell info

[Tim Parkhurst]

Probably more information than you ever wanted on photocells and
vactrols. Includes a few nice circuit examples...

Hopefully this will be some help to the Hacked Flanger and Quadrature
Oscillator projects (and others). As always, watch out for the word
wrap.
