Using microwaves to destroy speed cameras.

[love machine]

I know this is a bad idea and have looked at wikipedia for information about cavity magnetrons and it seems they are rather dangerous. I am aware that stray microwaves can cook your corneas. I was debating this fact with a chum the other day. How could you use a microwave guts to kill speed cameras. I know it is a dangerous idea and should not bear fruit, but just for theory's sake, let's debate it.

I rather like the idea of building a "Gun" with flashing lights and a "Woob Woob Woob" sound which kills speed cameras. Taking pot shots at those chaps on motorway bridges. Cooking gatso's.

Now, down to the physics. How do you stop microwaves? I'm well aware that the microwave and it's door creates a faraday cage. How could I shield myself against microwaves produced by my "gun"? Does the cavity magnetron have a decent waveguide to produce a beam? Could I extend this?

I am no way going to build one of these things but quite like the idea that if I really did have the rage I could contemplate building an effective one which would probably be sufficient to do the job.

The microwaves basically cook the radar sensor, snag is the shielding at the business end to protect the user.

I could probably figure out a way of testing whether the device works or not, assuming we weren't just talking theory

I recall diffraction gratings with about a 1cm grating working in a phys lab. However, I'm not sure how much "noise" is produced or whether it is a tight band of frequencies. I suppose I could attempt to build a faraday cage for my head. I had visions of using a microwave door as a kind of "welding mask" but the snag is the door is a part of the F/C and probably wouldn't stop microwaves by itself.

Hmmmm

I do like the idea of building the device out of things I can get my hands on without breaking the bank or travelling across the continent. The home microwave idea struck me as they are easy to get hold of and produce about 700W of energy which is a good starting point. The device would be something which could be aimed out of the back of a suzuki jeep and in an Ali G drive by stylee BOOKAAAAAAH!!!!blow the thing up. (in theory, remember)

The X-ray idea is not a snag as I have access to an old x-ray tube and power source, however would rather use high explosives in a home made gun

What we need to do is find out more about the nature of the beam from a 700W microwave. How much of a beam is it? What would a reflector be made out of, how would you construct a waveguide?

I suppose if you could construct a tube for the waves to travel down, you would be pretty safe from stray waves, unless you fired it at a suitable parabolic reflector with the focus on your head!

I'm also wondering about the power source, I would be tempted to use a simple inverter and run 240ac as per microwave.

As for creating a specific R/F frequency, how would you do that from things lying around? Would it be possible to modify the magnetron to produce a different frequency?

I'm not into creating a spectacular mess, I just like the idea of killing them. I liked the thermite idea but it is too spectacular. I also like the idea of a jammer but that's not permanent. If people get out there and kill these things en-masse, maybe..........

I'm sure the relevant department has people paid to sit surfing the web for signs of something interesting about to happen. I'm sure as hell not going to be at the bottom of it. I do hope that people take the idea, talk about it and think about it and do it.

I doubt the cops would recognise one




EDIT:- Can any of you academic chaps source this? Looks like a promising thing. Out of curiosity, what is it made out of?

Consider it this way, you get your dynamite out and blow the thing open like a tulip. The first thing which happens is that the cops start jumping up and down, the powers that be get the thing replaced. They have an eye open for future shenanigins and if you get caught with dynamite, smack smack!

Same with thermite, it's a dangerous mixture and you are a terrorist.

You unleash your ray gun at the thing and it toasts it in a subtle way.

1. They will not know it's been toasted
2. When they find out, they will have to troubleshoot the problem

This is a process which causes a lot of down time and is exceedingly difficult to detect.

It reminds me of being a punk when I was at school. Quickest way to get in trouble was to unload your swear vocabulary at a teacher. Best way was to use proper vocabulary and walk right up to where the line was drawn and shout from it.

I don't like speed cameras, I think they are a moneymaking virus. There is no way I'd consider zapping one in a 30 zone. Think of the children! I just basically want a scamera equivalent of what creosote is to fungus

I think we have the idea and with a few dotted around the country, in theory, most of the unfair scameras could be neutralised.

(All in theory of course)

How about a balaclava or a blue one.....what's the name again
