[Electro Magnetic Pulse]

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.

[frequency meter]

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.
