that's quick! a toroid takes forever and the only way to count turns is with pen and paper or one of those pushbutton thingies they use at club or theater entrances...

will this type of transformer work good with the simple oscillator circuit the RCM ignition uses? or does it need something more complicated like the 3W ignition that has a pair of transistors and a bunch of other crap?

any way to calculate the frequency according to the component values used?
