[sdiy] chaotic oscillator using 555 timers

Certainly, it isn't a Chua circuit (it's a wwcarpen circuit!).
But, it could very well be chaotic, at least at some settings.
Because, the 555s are coupled both by having their outputs
tied together, and secondly via the power supply.
Now, listening to the sample, there are some areas where it is just 
ANDing 3 oscillators, but (without throwing a frequency analyser on it)
I think it sounds random in parts. And probably chaotic at the edges.
Anyone put it thru a software analyser?

In any case, if you have 3 VCOs in a loop, you will get chaos.

..no arguments there! Keep hacking!
