To put in perspective -a small charge w/deionized magnetic particles binded w/graphite was to detonate 55,000ft. above kansas,the entire US would become "offline"-Any device using any voltage would catastroficaly fail for at least 2 weeks or until replaced. Think of bull in china shop,any charged particles dispersed near power grid attracts to inductance(magnetic fields)which in turn shortout all electronics.Now for your question, I would use an overload circuit.Imagine hitting a cars computer w/a stun gun,it would fry internal components.There is several ways,still got questions,e-mail me.
I don't have an oscciliscope, is there any other accurate means of obtaining a signals frequency? Know anything about residual frequency, or how to achieve anti-gravity? I also wired up an invention that takes oily,contaminated waste water and through a process,recycles the water and separates all dirt,fuel/oils,ect. For use at any company that has ,operates,or uses vehicle/machinery wash racks.Complies w/EPA,local laws. If any interest,I could share design schematics.
