[sdiy] chaos update

[D A F]

And as an added bonus, the scope trace sure makes a nicely chaotic Windows
desktop  ;-)

> topology from the first one that I previously posted, and it has a wider
> range of nonlinear functions.  With two comparitor nonlinearities, the
> circuit can make a quadruple scroll (compare the double scroll of the
> Lorentz system).  The system has a total of about 20 controls at this
> point, including a bunch of 12-position switches to set the parameters of
> the system.  Using switches is the only way I feel I can get reproducible
> settings.  The system has voltage control of frequency, loop gain and loop
> offset, the latter two of which  give voltage-controlled bifurcation.
