that energy field from your stargate could prolly jam cellphones.

Well, theoretically: if you transmit a strong radio signal, at the frequency cell phone operates, you could disturbe it's operation. But such thing is illegal and therefore not allowed to be discussed here!

That's true =)
I think being in close proximity to a tesla coil might do the job, too.

Ah fine - And because it's illegal, discussing about it is forbidden ?
Building nukes is illegal, too... myriad people talk about it in physics forums.

It wouldn't be illegal if you "accidentally" gave us some info. :cool:

I think its only illegal if you actually jam cellphones. Discussing theory or designing circuits probably not. I wonder if its illegal to jam cellphones in the privacy of your own home. Say, you have teenage kids... and you want to have some no cell times (homework, late night, daughter talking to her new scumbag boyfriend...).

Anyway, what was this thread origionally? Oh yeah, lazy college students...
There is no real way to filter those kinds of posts. I guess the moderator would have to decide if a post is a homework request. But how do you determine if they are requesting help getting started, or a completed assignment ready to to turn in? Basically, its always up to the readers to decide which topics to get involved with. Far as I know, this forum doesn't have storage or bandwidth problems, so its not hurting anybody but the lazy students...

Well the problem is, you would have to design it so its strong enough for your house, but doesnt go any further. Another problem is if you set the blocker in the middle of the house, you can block it easily. AL foil taped to one side of the wall, then its defeated. Assuming that you can still get reception on the opposite side.

Just turn your house into a Faraday cage. They put up one foil wall...you put up the other 5!

I'm not sure about slovakia, but here in the USA we have freedom of speech. I love it. Just talking about it is fine, as long as you are not stupid enough to do it. Big fines and big jail time are usually a fairly good deterent.

Anyways, I like the faraday cage idea. Don't they sell some kind of conductive paint that could be used for something like this.

I'm curious - Could nanometallic particles floating in a carrier substance ( painted on the wall ) create such a faraday cage effect ?

lol.

Discusing such thing is of course not illegal, but there is always some 'dumb kid' that will build such thing if he/she sees such article (and will cause some harm). That's why we don't want people to discuss such things in here.
The proper place for such discussion would be a school (collage)...

HarveyH42 · 19th August 2006, 12:50 PM

The problem with conductive paint or foil, is that you can't turn it on or off. I was just thinking of some practical uses of such a device in the privacy of your home. I personally don't own/use cellphones believe there are damaging effects associated with having a powerful transmitter so close to your brain. The billing scheme is almost as bad as credit cards. You have to be very careful not to exceed your usage agreement, or pay much higher rates...

I only mentioned cellphone jamming in a post, with several other topics that almost always start arguements over legal or safety issues that most likely will never come up in the real world. Basically, when the moderators or administrators ban a topic, then it shouldn't be discussed and the thread deleted.

Conductive is the key word in my statement. And perhaps several coats of it would be more effective. Of course there are other considerations, such as doors and windows etc. At any rate I think it would be interesting to play with (using someone elses money of course).
