Ahh, cool using a mosfet would be great. How do I go about selecting one, my pic can output 5V at 20MA. Not sure what I can find for an ignition transformer yet.
How do I go about calculating the proper oscillation frequency and a proper size mosfet for the igniter application, (formulas please ???)
About the valve intake, I will be using a check valve; the entire thing will have an adjusted density to keep it buoyant. Not sure what kind of force I will be looking at though for countering the water jet forces, may sink during that time if to high of an impulse.
Thanks
