hi everyone,
i'm trying to implement a chaotic oscillator for an electronic music project. i've built a few different chaos circuits in the past, but this time i have a couple of requirements that are causing headaches:
1) it needs to run on a single 9V battery. this isn't enough juice for an AD633 multiplier chip, which would seem to rule out the Lorenz and Duffing oscillators... (?)
2) i need to be able to modify it for real-time frequency control - so the time constant can be changed by only changing resistors. Chua's circuit and a chaos-modified Wien bridge oscillator I found on the web both contain inductors which makes them unsuitable. the plan is to replace the resistors with OTAs or maybe just matched FETs (i only really need a single decade of adjustment)
any advice, even just 'go read this book' or 'relax the specifications', would be much appreciated.
