Hi Lindsay,

Great tip :). I suppose I could just wind each control coil bifilarly with a smaller *tickle* coil to turn on the next coil. I wonder if there is any way to get a rough idea of how to tune the system to a specific target frequency? I?m guessing it would involve knowing the threshold voltage of the MOSFETs/Transistors and something with the inductance of the windings.

God Bless,
Jason O

OK I ran into another hitch here.

The good news is I got my MOSFET to switch finally :-). The bad news is that it seems to be limiting the amount of voltage that shows up across is when it is on. I am now using a charged capacitor as the voltage source and I charged it up to 200V. I then hooked up my signal generator to the base to switch it on and off, but the output would only go as high as the voltage my function generator was applying (~12V). I know that the MOSFET can handle up to 600V so I don't understand what the problem is. Here is the datasheet for the specific MOSFET I am using: http://www.ortodoxism.ro/datasheets/SEME-LAB/IRF460.pdf.

God Bless,
Jason O
