> "It’s hard to build an oscillator" I would beg to differ. It's hard to not build an oscillator. An awful lot of digital design is avoiding building oscillators all over the place. Incidentally, the coolest anti-oscillator I've seen used the back EMF from a relay to push a transistor past its breakdown voltage, and that was the oscillating element.
