If I only had the knowhow (computers, electronics, program, problem)

If I knew about tech stuff, I would invent a machine/program that would fry the computers of telemarketers and robo calls. I would invest a fair amount of time and funds, if I only had the knowhow...

It's called an Electromagnetic Pulse (EMP). All you need is your own thermonuclear warhead fired at significant altitude. Good news! Kim Jung Il says that he has totally got your back.

The problem is that it fries all other electrical/electronics everywhere else too for hundreds or thousands of miles depending on yield and altitude.

Details, details ....
