Microwave gun built from a microwave oven, a few computer fans, sheet metal, and wood.
In addition to what is shown in the video, the gun will jam any radio or cellphone within a large distance.
Warning: 1 Kw of microwave energy is enough to cause blindness in a matter of seconds if you were to stick your face too close.
Many people seem to be interested in tighter focusing, so I’ll answer a few off the common questions here: tighter focusing with require a physically much larger device, using a horn antenna is simplest, but beyond about 25-30 decibels of amplification , the size of the horn becomes impractical, and you should instead opt for a feed horn matched to a parabolic dish.
The materials used for the waveguide and antenna must be metal, and the waveguide must be at least about one wavelength in width (4″ or 10cm) for maximum efficiency.
