[sdiy] Chaos Boards Shipping

[Ian Fritz]

Hello --

I decided to indeed have some boards made for this project, and they have 
arrived and been tested.  Several people have indicated an interest and 
will be getting boards this week.  If anyone else is interested they need 
to contact me (offlist, please) fairly soon, as it looks like these may not 
last long.

There was a question raised as to why there is no voltage control.  Since 
the chaos patterns change so rapidly with parameter variation, wide-range 
voltage control is not all that advantageous.  Since the circuit needs to 
be driven by an external source,  amplitude and frequency modulation of the 
source can be used to modulate the chaotic pattern.  The schematic I put up 
a while back for another system had voltage controlled rate and pattern, as 
do the more recent conplicated systems I have put together since then.

The current project is really a great way to get started with chaos.  And I 
am finding that cascading two of these circuits has some really interesting 
possibilities.
