I've only read some vague reports about initial tests and stuff but it sounds good. It uses focussed EM waves to rapidly heat the targets skin. Which I thought sounded like a microwave. I then thought "hmm? I could tear apart a microwave and use the emitter and some Lead to make a long range ignition system. I'm working on it and was wondering if any of you knew about Microwave ovens??

I made one, they will destroy praticly any transistorised equipment in the path of the beam I have some pictures but I am having trouble posting them. you can see them on the front page of my site at

That sounds kinda like an EMP. Has anyone experimented with EMP grenades or just EMP in general?

That's HPM (High Power Microwave), not EMP. EMP is a short, very powerful pulse of maybe only a hundred cycles, HPM is in bursts of much greater length, but less power.

yes, mine is high power microwave, it outputs microwaves at every other cycle on a 60 hz wave, withc is 30 pulses a second
it is really simple, it just is a microwave magnetron with a diode, capacitor and a BIG unlimited current transformer. I managed to use all the parts from one microwave, even the blower. but it gets VERY hot and will sometimes trip circuit breakers after being on for only 4 min. I need to get a good variac and a bettter em field strength meter for this

it is directional, I never stand in fornt of it while it is on. I can measure the microwave fields with a voltmeter probe I have that has lots of coils of wire inside, and a small circuit I am in the safe zone, my death ray pegs the meter when it's in the beam otherwise, nothing

j/k Pyro, I'm sure you know not to get in front of that thing.
A question though. The picture you posted shows the magnetron/magnet/coil assembly (and all other parts) exactly as used in a conventional microwave oven. Wave propagation from a MW source mounted in this way will be almost hemispherical, that is, not very directional at all. Have you experimented with a waveguide or horn to narrow and concentrate the beam?
A problem which may be causing excessive heating and high current draw is the absence of an effective load. Prolonged unloaded operation at high output levels will quickly destroy most transmitting tubes - and klystrons/magnetrons are no exception.
A note on the original topic: From what I understand, the gizmo developed by the Army for offensive use is a very high power, highly directional millimeter wave device. While a microwave oven operates at a frequency of 2.45 GHz, millimeter wave frequencies are in the band 30 GHz to 300 GHz - a completely different animal.

I now have a grounded copper flange on the insulating part of the tip of the magnetron.
as for sophistication and making it run at another frequency I like it the way it is it is simple and it works. the beam is about an inch wide and I want to make a better more concentrated waveguide other than just crimped copper pipe but it cant touch the tip of the megnetron and i think I need to get the waveguide the right hiegth. I dont really care if the thing burns out beacuse I can get spare parts at a surplus store nearby, but first I would just got to the dump and get another microwave. I want to get some high capacity capicitors and some gell cell batteries for a portable version. as for the heat, all microwave magnetrons put out alot of heat, but microwaves use that heat also to cook the food, that is what the fan is for. the transformer I have will put out 2000 volts at a half an amp! that is some serious wattage! that will easily fry you and kill you in a heart beat (your last) microwave transformers can melt glass with their hot arcs

I read in New Scientist a while back that they made a proper phaser, as i understood it neway,it sent electricity down two paths of ionised molecules or something.Shoulda payed more attention in my Physics lessons I guess.The actual "phaser" thing was about the size of a kitchen table they said.

Apart from using em radiation there are several "phasers" similar in design to an Air-Taser. Pathways for conducting electricity are
wires, shot out from the taser
+ cheap, light weight
- low range, works only at line of sight, one shot device
electrolyte fluid streams, look here:
http://theforum.virtualave.net/ubb/Forum4/HTML/000150.html
+ can go over obstacles, multi shot, cheap
- low range although higher than wire devices, bulky electrolyte tank for longer operation
uv-laser beams. 2 laser beams are used to create channels of ionized air which conduct electricity.
+ long range, multi shot, precise targeting possible
- uv-lasers are damn expensive and need a bulky power supply, works only at line of sight

If you get a high power pulsed CO2 laser, then it'll be able to ionise a long thin cylinder of air which you could send electrical currents down. But unless you send a lightning bolt down it there's no point, because the laser beam will destroy just about anything by itself!
