Does it works to put together some IR-lasers, to fool the police?

[Psychopatic]

About 2 years ago I got a speed-ticket on 2 400 SEK (about $350), when I drove 43 km/h on a 30 way-limit road. They took me with a laser. I have read some about "laser-disturbing". It is forbidden in Sweden, but the ticket for such a thing is only 900 SEK ($130).

It's not my goal to overspeed, since I got my ticket I am trying to hold the speed.

But I'm just curious... Is it possible to assemble some IR-lasers on the front of the car, to fool the polices lasergun? Do I have to spread the beam with optics?

I don't think that will help you, they are useing there own beam. You would have to find some way to disrupt their laser gun.
Your lasers would have no effect!

Ok, thank you!

It is legal to sell laser-disruptors here, but not to use them. I thougt I could build my own from a number of old CD-players. I readed some article about a guy who had some kind of laser-device in the front of his car. But he said it was for automatic opening for his garage-door. And he got away with it!

I have heard of radar jammers but not a laser disruptor.

My understanding is that these use ir laser diodes (un focused to an extent) and emitt light pules that act like white noise droning out the cops.

How a laser gun works is it measures the time that it takes for a given pulse to return to the gun. The diodes confuse the gun. They also make special transparent paint that scatters the laser gun to reduce it effectiveness.

I think it would easity to build your own if you knew what the out put is.

I've considered getting these, but I got a 9500xi instead due to the fact that all the cops around here use radar rather than laser.

Yes, radar jammer is also forbidden to use here. The automatic cameras uses radar to measure the speed. It' more rare that the police uses radar directly to measure speed.

But the article says:
Laglig laserstörare beslagtogs - www.trafikjuristen.se

In english:
Legal laserjammer confiscated
An effective laserjammer was confiscated in Uppsala (a city in Sweden). Despite it was legal. The policeman started the measure on the Audi at 300 m. In vain he tried to get a measure-result. When the car was at about 100 m, the police gave up. But he stopped the vehicle to investigate what the measure-problem depended on.

In the front he found a laserjammer. The policeman contacted his boss who decided that the jammer would be confiscated. This decision was however wrong. In this time it was legal to use such a device. The driver got his jammer back, and economical compensation for the jurisprudence.

"this is Lieutenant Obvious speaking. Speed limits are there for a reason. And that reason is NOT so that you can find hideously elaborate means of circumventing them. Over."

I speed all the time sure i see the posted limits but i only speed on highway's when the road is clear. wheres there's children i get beeped at for driving too slow. The only thing i really have to worry about is a cop or an animal jumping out out in front of my car while on the highway late at night. I have a radar and laser detector but a jammer would def be nice. My friend who is a police officer even has one in his personal car. There just expensive but they will def block them and then when your detector is going off lower your speed as the laser wouldn't come up with a reading and by the time you pass them your down to the speed limit. If cops are doing it then we should also be able to do so. I see no harm being done with jamming there signal.

How would you test such a device anyway? Two choices I think...

1. You build it without a gauranteed outcome, (costing what? $200-$300+?), then find it didn't work and end up with a ticket.

2. You spend money on a laser device similar to the Police's, spend more on developing your countermeasure device, (and then find it possibly didn't work anyway.), having spent many more hundreds of dollars than the fine.

It would be cheaper not to speed wouldn't it?

With such a device, some lunatics may also be tempted to taunt the Police by repeatedly tearing through their speed traps until shot!

None of these scenarios seem to be cost effective to me.

I would buy the device for $400 dollars. 2 tickets would cost me that much. I wouldn't build one then test it out just just plain stupid. Use Google you can find what u need. there already available for people to purchase. If people want to tease the cops that's there problem not mine as long as they do it without endangering people lives there stupid if there using it for that but I'm 26 not 18 and i don't play games with cops just try to beat them at there own game u laser me i block you. The reason i would use it is to not get a speeding ticket while doing 70-80mph which 70 isn't that to far over the speed limit but you can still get easily get a ticket. For $400 lets say it last 4 years it would be very cost effective for me. That's me though and just my opinion.

of course not speeding would be cheaper but i don't think that's what this topic is about. I'm pretty sure 90% of the people on here have sped before or even got a ticket for speeding. What if i get pulled over and the cops a moron and winds up shooting me because he thought my key chain in my hands crossed over the steering wheel was a weapon and opens fire. $400 would have stopped that from happening. Cops have to show that the laser was calibrated and what it read on the citation so if they didn't get a reading and i slowed down and they began to follow me to try to pace my speed i would do 1mph under the speed limit until they were gone. Plus $400 isn't that much for me. So anything else you'd like to ask why i would spend $400 to keep from getting tickets especially in NY, and the fact that after 6 points in a year you owe DMV $300 each point after that is another $25, and i wouldn't have to worry about getting my license suspended. I've been pulled over just staying with the flow of traffic because they picked out my car to laser while i was doing 70 just like every other car. I have a "heavy foot" as they say.

http://jammersstore.com/ they have been out for a long time this isn't something new. if you don't speed don't get one. If you have a heavy foot then theirs plenty to choose from so you can avoid getting tickets.

Since I got my speeding-ticket, I try to always keeping the speed-limit. Maybe sometimes more at the high-way. But I was just curious! And now here, I think is illegal to posses one, so if you buy one for example $100. They take it, and you got a ticket for possesion one!

You have to hide them where they can't find them eg; the bumper, behind the glove box. be creative. If it's illegal for you to have then i would suggest not to buy one. Why try to build one when 1 there already out there, 2 there cheap, 3 there illegal for you?

Around here, a jam shows up as a E7 error, "jamming detected" on the lidar.

The modern lidars are "range gated"

I'll let you google how that works.

Laser-speeders jammers are simply a block of IR leds that blinks at 6nS for each 50nS (more perfectioned units have different frequencies patterns, that includes 14nS and 50nS pulses), and just disturb the receiver, "fooling" it with multiple readings not related with the real one .....

Some countries allows them to be mounted, some others allows only the "detectors", and not the jammers ..... here in Italy, as example, they solved the problem banning ANYTHING that can be used for avoid them, including maps and "points-of-interest" databases reporting the detectors positions for GPS navigators (another example of the stupidity of our laws ) .....

It's easy to build a jammer, but check before if your country permit them ..... if not, you can use the "stealth" anti-IR paint , and a receiver/detector, maybe .....



EDIT: ROTFL ..... i've done some researches on new models, and found that someone already took my original idea to mask a jammer as a "parking helper" device (yes, trust it or not, this was one of my projects ), and started to sell it as complete product ..... read here .....

The Laser Star is not sold or packaged as a ‘laser jammer’. The handbook clearly shows it is an operational device that is used for parking and which operates on the same, licence free wavelength of 904 nm as do many other devices. Obviously some naughty people use it as a way of defeating laser guns.

I guess i had to patent this idea, when i started to talk about it on public forums a pair of years ago, LOL

need to get an updated jammer. i've seen my friends model tested by our cop friend while he wasn't speeding because though he's out friend were not gonna put him in jeopardy that error didn't appear. the laser was jammed and it5 was as if it was malfunctioning. i believe his model was a bel vitor or something. not some cheap jammer that tells the cops, "hey i have a jammer" lol i feel bad for the sucker that buys that one.

where do u live? just curious also look up youtube videos.

A range-gated radar system which includes a phase modulator that modulates n r.f. generator with a signal which may be binary coded. In a preferred embodiment, the binary signal is a periodic signal of 2N -1 bits per period. Starting at some arbitrary point in the sequence, K contiguous bits are transmitted then M contiguous bits are passed over, then K more bits are transmitted, and so on. The quantities M+K and 2N -1 have no primary factors in common. The radar system may be a doppler radar system using balanced digital processing which involves separating the upper and lower sideband components of modulation that exist in the return radar signal as a result of the motion of scatterers and subtracting them.

you know that was patented 30 yrs ago right plus i see no mention of it jamming a laser.

finally someone knows what there talking about. that sux you idea was made years later. U get another great idea liken that be sure to patten it like you said don't tell anyone tilll the prototype is even made. ever see a flash of genius?
