CuriousGeorge113 was the first one to write us about the homemade HERF gun an engineer unveiled at Infowarcon '99. All stuff that you can buy from a hardware store, and disable computers at varying range, depending on size. The current model does not do permanent damage, unlike EMP.
As the trials of life continue to take their toll, remember that there
is always a future in Computer Maintenance.
