Re: How to shield your electronics.
Great thread.
I have an FM transceiver that I keep in a US military ammunition can that I plan to use in a shtf situation. I have read that these make suitable Faraday cages. Would you concur, Steven? Thanks in advance. |

Hi Steven, Colours of wires must be totally different between our two countries, the following colour codes are for Australian Use ONLY Yes i know the wiring colours for both AC and DC here in Australia. DC - Positive is Red, Negative is Black. AC - Earth is green or can also be Green and Yellow, Neutral is Black or also can be Blue, Active is Red or can also be Brown. I just had this thought that a few years ago i had read somewhere that the AC Neutral (Black) was now being tied to earth. . ALL HOUSEHOLD WIRING AND REPAIRS MUST BE ONLY CARRIED OUT BY A LICENCED ELECTRICIAN. . . |

Re: How to shield your electronics.
i believe it is also necessary to insulate the radio from the box, on the inside.

Re: How to shield your electronics.
Yea I've been thinking that maybe it would be good to line the box with rubber or some sort of insulator, although most things are in a plastic case so I guess that should do it.

This is true for all type of activities (repairs, modification, measurement, etc...) on the actual electric network of any house. But... you don't need an electrician to shield your electronics if you use new wire and shield (metal box, faraday cage, foils, etc...) and ground it with new wires network. As long as you don't touch the electrical network and do not touch electrical power. If I may add this: Many people asked me through private message if military are/will use it against cities, citizen, etc... It wasn't my original idea for this thread, but here is the information I got about it. There are many different kind of EMP military can use, from micro-wave to infra-red, without mentioning all of them. And there is not much protection against these weapons because of the magnitude and precision (target). The best and more affordable protection against these weapons are to my humble knowledge lead layers. Because of it's atomic structure, lead absorb some effect of these waves. Faraday cages are also very efficient, but both these solution are more expensive and time consuming to set them up, both of these solution need to be connected to the Earth ground. Skeptical made a very informative comment about it on a previous post. Here is a link to Faraday Cages tutorial: http://www.unitedstatesaction.com/em...aday_cages.htm Namaste, Steven Last edited by Steven; 10-30-2008 at 02:15 AM. |

Re: How to shield your electronics.
After reading in another thread about microwave ovens.
I think that if you were to earth one then it should be ok to shield your stuff. You could use a old one which is not connected to power. If your in the UK or Oz then it would be earthed if plugged into the mains. In the UK you could just remove the fuse so there is no chance of it turning on and cooking your stuff, and it would still be connected to earth. Ok it's not going to be very big, but big enough to save your ipod, a radio etc Anyone know a reason why this would not work well as a Faraday Cage?? Last edited by Swanny; 10-22-2008 at 10:30 AM. |

Re: How to shield your electronics.
No probs Steven glad to be of help.
Just talking to a friend who threw away his old microwave yesterday, I could have used that. Good idea about adding foil to it |

Re: How to shield your electronics.
Would it be possible to ground the entire house?
I live in a single detacted home and I remember reading somewhere about a 5 feet antenna on the top of your house.....unfortunately there wasn't a lot of info to go on. Any help is much appreciated. Thanks and have a great super day! |

Re: How to shield your electronics. v.s. Voodoo
"If you worried about your body, especially your brain since it's an electro-magnetic device, well shield it, lol. I mean you can put antennas on the roof of your house, 1 antenna wire 1/4 inche by 5 feet long, covering a sphere of 20 feet, and protect the entire household. The important is conductivity (metal) and good grounding (deep in earth)."
This will not work and does absolutely nothing for you. The idea of putting antennas on the roof top must have come from the idea of lightning rods. EMP is not like lightning. You cannot 'draw' EMP away from things in the same way as you can with lightning. Common EMP has little or No effect on your brain. Also, if you ground something, the ground wiring Must be very short distance from the shielded 'item' to the actual Earth grounding point or the so-called ground wire will act as an antenna instead of as a grounded circuit. Using housewiring grounds in wall sockets is not a good idea and may Not be effective. Copper foil is a better option if you wish to create a good faraday shield. Aluminum - is ok for shielding the Magnetic component of the Electro-Magnetic pulses and will suffice overall if done properly. Antennas and any wiring attached to a device should be disconnected for best protection. ---------------------------- On second thought, maybe it is time to go buy some 'wabbit ears' (an old-stlye of TV antenna) and put them on my new hat: http://www.rogue.co.za/html/more_headwear.html Last edited by Bleep!; 10-30-2008 at 08:46 PM. |

First, I agree that common EMP has little effect. But we are NOT referring to common EMP in this thread. Great magnitude EMP can affect the brain. Here to back my words: http://www.blurtit.com/q642109.html Here experiments on rats: http://ieeexplore.ieee.org/Xplore/lo...number=1282261 Last, yes copper is a better conductor element, but it is more expensive and does oxide much faster.

Re: How to shield electronics.
Antennas concentrate EMP? oh well, have it your way.
Nearby Massive metallic structures may increase the fieldstrength of EMP but will not 'suck' the EMP away from you or away from other nearby things. The following (from the link) is True: "The only two requirements for protection with a Faraday box are: (1) the equipment inside the box does NOT touch the metal container (plastic, wadded paper, or cardboard can all be used to insulate it from the metal) and (2) the metal shield is continuous without any gaps between pieces or extra-large holes in it. Grounding a Faraday box is NOT necessary and in some cases actually may be less than ideal." A nuc explosion is not required for EMP to be produced. A conventional device can be easily constructed to do the job. This is all fine and dandy but does it really matter? Ponder it all. |

Re: How to shield your electronics.
Most of the posts in this thread seem highly speculative in nature.
There does not seem to be much definitive information in public, and people who understand RF are few and far between. Bleep! seems to be one of the few that understand. What worries me, is that people talk about EMP as if it were some kind of constant. EMP's can of course be of varying strengths. The need to protect against EMP caused by a local nuke, is different than the need against one caused by a CME type phenomena, or a high up "big" nuke covering a wide area. The earlier advice that cars would be unaffected is dodgy since most modern cars are very dependent of digital technogy. It is true that if people start slinging nukes about, we would have more to worry about. A.. Last edited by Anchor; 10-28-2008 at 03:26 AM. |

Re: How to shield your electronics.
IMO I see no reason why they would want to EMP us, if tshf they would want us to stay in doors and watch the tv/listen to the radio so they can feed us BS and tell us to be good little people. They can easily turn off the phones and the net to stop us talking to each other.
I still like the idea of protecting your stuff just in case. The sort of cars that would be ok after a EMP hit would be those that have points, so if your car is about 20 years old and you weren't driving it at the time it mite be ok. An old mini would be good. Anything with a ECU would be no good. A diesel engine is very basic and doesnt need electronics to run once it's been started, |

Since, I work for a large Electric power company and already have lived this kind of problems, I put some simple advices, not expensive, to protect one electronic devices. Now, if you don't agree it's ok. But I'm not being speculative, plus I provided some useful links since I can't begin to write a book about the topic on this thread. And yes, EMW constantly comes from the sun. Namaste, Steven Last edited by Steven; 10-30-2008 at 01:29 AM. |

Re: How to shield your electronics.
Thanks for the responses guys.. I can see that this is no easy topic and depends on what we are defending against.
Let's say it's a "future EMW of great strength coming from the sun according to Henry Deacon's somewhere in 2009.", then I guess the antenna thingy would help. So if I got this straight, I would put this antenna (every corner) on top of my home...do I run the wires down the side of the house to the ground? (from the antenna), or do I find a metal piece (outside water spout) and attach a wire to it and the other end to the ground? I also have a scooter, I think that would be safe from a EMW (it's a manual start). Thanks and sorry for my ignorance. |
