Noob Q about inverter for an ornithopter Answered
I was looking in the back of my Jameco catalog the other day and they listed a product called "Muscle wire". It's apparently a nickel-titanium alloy that shrinks as it heats up.
It occurred to me that I could flap ornithopter wings with it (a really small ornithopter). I was trying to figure out how I could switch voltage from one pair of wires (the flap UP wires) to the other pair of wires (the flap DOWN wires) without a microchip.
I came up with something I'm sure wouldn't work involving a couple transistors, a diode and a cap. Today on wikipedia I figured out that what I was doing was something close to an inverter.
So here's the question: Anyone know of a simple switching circuit that runs on a/c power and does not have square-wave switching characteristics?
I'll keep researching this myself, but sometimes 'tis quicker to ask the big-brained and kind hearted (you know who you are).
