I think it's been almost two years since I first heard of "EMP signal jammer", and I've seen all kinds of video on Youtube to make one. Over the last two weeks, I've spent some time trying to build an electromagnetic pulse generator (EMP) from video and images on the Internet.

Using Emp Jam Jam, strictly speaking, there is no Emp generator at all, but only one "emitter" generates a few MHZ emission frequencies. This interferes with electronic circuits such as calculators and alarm clocks. In addition, you can do cool things with them using fluorescent lights or energy saving lights, instead of connecting them to energy.
