variable pulse width square wave signal generator with protection from inductive spikes

[Inquorate]

I believe this type of square wave signal generator is crucial in investigating tesla and bedini type effects. I've been struggling for a long time to get a reliable square wave pulse, and this one is a workhorse. Thanks for your comment :)

if this is for a resonance coil. could you use the ring down potential to drive this. that way you can always be in tune to the resonance. that is if you monitor the voltage after on time you can hold the on time until the ring down reaches a minimum set point and then trigger a new pulse that way you will always be in tune. no matter the environment. just a thought. i have several pats on power management based on Tesla tech. i know that fast and crisp switching is mandatory. just FYI. thanks
