Man blocks valley girl's cellphone

[judasiscariot]

I saw this link on Digg today.  It's about a man that uses a device to emit a strong radio signal to block any cell phones within a desired radius in order to silence the conversation of one annoying valley girl.  It also segways into a nice piece about how this is a FCC no-no.

Clients, he said, include owners of cafes and hair salons, and a New York school bus driver named Dan. “The kids think they are sneaky by hiding low in the seats and using their phones,” Dan wrote in an e-mail message to Mr. Thakkar thanking him for selling the jammer.

What's the point in that?  He should be happy that some kids are quietly talking or texting instead of talking out loud to their friends all around them.  What a waste of his money.

Can you hear me now? NO! Good,” the purchaser of a jammer wrote last month in a review on a Web site called DealExtreme.

That's right near the thread about how the pla is a bunch of elitist jerks for removing the jammer thread.

You reminded me of that and it made me giggle.

It would be a good thing to have when you're behind those people on the road that can't drive and talk at the same time.

I wonder if something similar could be used to block radar. Like if you were transmitting a very powerful signal on the same frequency as the radar gun would it affect it so that you'd be invisible to it?

In order to do this you'd need two line of sight transmitters mounted inside the car windshield at 40 and 320 degrees with some sort of power source hooked up to it.  I'm not sure on the technical details of the wavelength and frequency but I'm sure you could accomplish some jamming this way.

That's a good question. I'm sure it's possible.

From this site: "Active radar jammers work on the principle of interfering with or overwhelming the doppler shift that occurs from the reflected radar beam that police RADAR guns require to obtain a vehicles speed."

[s1acker]

"While active radar jammers are most certainly illegal (unlike laser jammers), they are mostly ineffective, especially against the latest digital RADAR guns."
So even if you had one it probably wouldn't work these days.

My uncle has one in his super fancy porche, it works. Maybe its fancier than what that article is talking about.

I guess I'll have to hold off on my plans for a warp engine go-cart.

I have a 4 cylinder that I pulled out of an old car that a friend wants to put in his go cart. Keep an eye on the Darwin Awards folks.

It can be done. I don't know what kind of go cart he's planning on using but I would suggest reinforcing it everywhere so that it's basically a roll cage on wheels. The engine is going to make a lot of tourque (At least in proportion to the size of what it's pushing.) too so make sure that axle and everything is strong enough to withstand it. Is the engine from a FWD car? If it was front wheel drive that will actually make it a lot easier to do since he won't have to cut a drive shaft down to fit the shorter distance. It would be a lot of work and take some careful planning but if done right could be the sickest go cart EVAR.

I just keep a gun in my car.  If a cop around here tries to write me a ticket, BLAM!  In the face.  The cops around here know to leave me the hell alone.
