Another way to get the pulses, is to use a joule thief, with a bifilar coil. joule thief, pulses a darlington transistor open and close. this darlington is then hooked up from the collector, to the pulse transformer primary, and the voltage supply positive.
The pulse transformer, is then pulsed, when the collector flows to emitter to ground. In a joule thief circuit, this happens really fast(40khz). But relatively low compared to the resonant frequency of the coils (550khz).
I need to develop this, So I have a pulse thats high voltage.
the resonant frequency of the bifilar coils can then be tuned down, to match the joule thief frequency, by adding capacitance to the coils
