... and don't place the mic too close to the #$%& hole :-X who knows what might come out ;D

hi to all, thanks to audioguru for all the answers. They're all enlightening. I'm not much into electronics, but I'm collecting topics on alternative energy sources - wind, solar, etc. Part of my collection are plans for 5,000W inverter which I downloaded from the internet. Sorry I can't share it here because it's not my property, but I'll send them to Ronnie. (Also, they're not purely electronics devices) I haven't tried building any of them yet. Perhaps Ronnie could go over the plans, do some modifications and publish them. Thanks a lot to all you great guys !

hi, I'm a newbie. I'm having doubts about using square wave output for anything other than a resistive load (e.g. an electric bulb or an electric stove). Using it on a flourescent lamp is ok though, 'cause they come cheap. But for tv and anything else I think there should be some sort of wave- shaping circuit to come up with an output similar to a sine wave. Perhaps someone could give us a schematic for this purpose. The circuit is designed for 50 Hz. From the diagram, it seems C1 and R2 controls the clock. What values are needed to change it to 60Hz? Finally, if I want a to double the power, can I simply put a larger transformer and double the number of transistors?
