the topic is pretty self-explanatory
because these cmos chips dont require much power you can often patch an oscillator to one of these circuits instead of using a battery or power supplies

this is one of my favorite features of these chips they try to run off anything and will sometimes even work for a while after the power has been removed

its a simple method for generating interesting tones and its especially useful if you havent gotten around to building many modules yet... if you build two modules out of almost any cmos chip and enable one of them with this feature you can have some good fun before building additional modules

That's a great idea and something I'd very much like to try out.

I've had a lot of fun using the circuit-bending technique of power starvation with CMOS chips -- putting a 1M pot into the V+ line works wonders for 40106 oscs, sending them spinning, especially if you've made several oscillators from the chip's gates - they seem to fight one another for the limited power available.

(edit -- ahh, just saw the same starvation method mentioned in the noise thread!)
