To clarify, I WAS abusing my little FET.and POP goes the MOSFET.
Sorry!! then this is something I would not prefer to make.
I realize it just ain't worth the trouble.
But it is good for a show or like carnival or something
It was a somewhat weak FET, and I had it at about 40kHz, 70% duty cycle, no dampening resistors, and it was the only MOSFET.
If I had used a High-side/Low-side driving setup at a lower duty cycle using a sizeable MOSFET I could probably get a good volume from the thing.
I plan to make a setup that works well with parts avaliable from radio-shack/goodwill/hardware store so that more people will be willing to build these, but it's a ways off
