The Personal EMP-Bomb
AFAIK Win Schwartau
was first to describe do-it-yourself EMP weapons in his book "Terminal Compromise"
back in 1991. It had to happen, someone actually built one.
To quote from the I-Bomb website:
The rapidly approaching ubiquity of technology and its inevitable but rarely discussed terroristic use demand for immediate exploration and development of technology disruption devices. In the ensuing world dominated by technology and information, the true culmination of power will rest not with the institution controlling the information but the organization, group, or individual capable of disabling, altering, or destroying the underlying support structure of information: electricity, telecommunications, and computers.
