How to shield your electronics.

[Steven]

Hi all. I am technician in electronic since several years. I know many question arose about how to prevent Electro-magnetic wave to disrupt your electronics tools.

First of, I am not saying this is the only solution, but it will work on many types of EMP, coming from the sun or other sources, except military weapons.

Also, this solution is simple and cost almost nothing. That is why I'm putting it here. I work for a large electrical company and in 1989, we had a major shut down because of unusual Electromagnetic Waves from the sun that hits the Electric Network and most protections opened. But it also damaged many DC components in the province. We receive constantly EMW from the sun and earth act like a filter, that's the reason for the heat. So we need it to live, but sometimes, a wave of large magnitude hit some spot on earth and may cause damage. That's what Henry Deacon was predicting for sometimes in 2009.

Second, an electromagnetic pulse has a frequency, or many frequencies, it is called "noise". When the amplitude or strength of the wave is too high for your electronic system, it can damage components in a physical phenomena called induction. The wave has to be "reflected".

To absorb/reflect it, you need to build an "metal shielding" surrounding your electronics and this "metal shielding".

You can make a shielded box or Faraday cage to store your electronics toys when you don't use them.

Here is an explanation: http://standeyo.com/News_Files/NBC/EMP.protection.html

Everyone who has questions, answers, or other information are very welcome to contribute.

I hope it helped, Namaste, Steven

Hi thanks for the tips, would multiply FOIL wrapped around a box work? At a garage sale last week I picked up a large 6 foot roll of foil with backing I thought of maybe using this? Also do you know would this effect your car engine? Would you only have to protect the battery or the whole engine? Would CB Antennas work to catch the signal? Sorry for all the questions?

I was of the understanding that it is the ECM or ECS - Electronic Control Module/System electronics that will be effected in modern cars, not the battery.
That is one reason why the older cars, or the older diesel vehicles would be better suited as they would not have the ECM - electronics installed.

Spot on Tez. :thumb_yello:
Also, if the pulse is strong enough, to which it probably will be, it could damage alternators and starter motors.
Take care.

Hello Peace. I'm glad you are interested. Here some clarification.

Yes, multiple foil will work. The important is having a good electric conductor, aluminum is one, like silver, copper, iron, steal.

Don't bother about car engine, it's an explosion (gasoline) motor and it won't be affected. The batteries will take it. Their capacity and power (Amp/hour) will support it. But the electronics of your car, sensors, processors, memories, etc... might not like it. Recent cars, 2000+ years, have many of them from electronic starters to flow fuel control. But I wouldn't worry about it because the frame and structure of your car will act as an "metal shielding" and will reflect most of the wave.

Yes, CB antenna will do.

What is mostly susceptible to EMP is electronic component, which work on Direct Current low Voltage, 5 VDC to 24 VDC, and haven't a high capacity to support high frequencies and high magnitude. Any devices working on 120 Alternative (50/60Hz) Current Voltage, 120 VAC and higher, will absorb the impact even more if it isn't running and unplugged.

The noise is an electromagnetic wave of high frequencies, device running under alternative voltage/current are made to work with frequencies, up to a certain limit in frequencies/amplitude. But electronic component, like processors, memories, etc... are not made to deal with high frequencies and especially if the signal (noise) is strong. They can heat and burn from inside.

Only these need to be shielded in my humble opinion.

I hope it clarifies it.

[davefla73]

here is a site that is awsome for survival, it is the best iv found on EMP protection. I metal shed grounded looks like you could store a lot in there and would be safe. look for yourself :)
http://www.endtimesreport.com/EMP.html

[Squeptikal]

Hi Steven. Thank you for bringing this up. There are some important ideas to consider. First, anything pysically connected to the power grid i.e. the wall outlet is going to get zapped by an intentional EMP device within the correct proximity. Literally within 5 miles from the epicenter of a military type EMP device will be completely fried with no hope of repair.

Even store-bought EMF supressors & spike arrestors won't do. You need to have a standalone power supply buried in the ground and not connected to anything above ground to accomplish this level of protection against military devices. In addition, an air-burst nuclear device will also create enough of a pulse to destroy all grid connected equipment AFAIK.

You can shield you automobile somewhat and this requires grounding straps connected every 30 inches along the edge of the hood for instance. I recently bought an old police car which has this type of grounding. My CB radio works very well partiall because of this electronic hardening. A direct strike within the saturation zone and no electronic anything will work afterwards. It's cave-man time!

Any low voltage circuit is at risk from even greater distances than the 5 miles. Hopefully, a combination of being further than 5 miles and having some offline equipment stored below ground will probably survive. However, there won't be any radio or T.V. stations, Internet (except possibly FiOS), or electricity in the wall outlet immediately following an tactical EMP strike.

Yes, aluminum foil helps prevent induction and aluminum also has diamagnetic properties which not only shields against magnetic induction but also electrostatic discharges. I have read some interesting things about Tesla's machines creating scalar waves that completly render shielding useless. But even Tesla's machines don't penetrate much more than 6 feet of earth unless very close to the target.

This is why the military geniuses built over 100 Deep Underground Military Bases (DUMB's), some of which are rumored to be thousands of feet under rock & soil. The facilities are completely isolated from the surface power grid and are even hardened against a direct nuclear assault.

A Faraday Cage will shield from radio frequencies and weather-induced spikes however an EMP creates a square wave orders upon orders of magnitude greater than a lightning strike even through water.

There's the old saying "there's no replacement for displacement" and it fits here as well. Displace a lot of soil, leave survival equipment (such as wind-up recievers, HAM, CB, GMRS & FMRS radios) disconnected from antennas with the antenna leads grounded and without batteries and you might be the only kid on the block with a working device after the ping. I have a speaker connected to several turns of wire connected across the terminals which will make a loud SNAP sound in the event of a strike.

Thank you for your good advice and for creating this thread.

What about making a lead box to shield stuff?

[Steven]

Thank you Squeptikal for all this very welcome information. I really appreciate it.

What about making a lead box to shield stuff?

Absolutely! Lead is very efficient in manufacturing noise reduction material, radiation shielding and x-ray shielding. If you can afford it and be cautious, lead can be poisonous.

I checked out the price of lead today, a roll of code blue is now at £80 and thats trade.
I did have some scrap lead a while back but took it to the scrap yard.
Oh well :)

[Swanny]

I've been thinking about this, in the UK the electricity circuit in the house has a earth.
All our plugs are 3 pin and most appliances have a earth.
I know it's the same in Oz but not sure about other countrys.
Maybe because we are earthed already the EMP (if they ever did use one) mite not work so well???

[IRKCOD]

Being a complete nerd when it comes to electronics -

Is it possible to make a Faraday Cage, to protect your electronics, out of 'chicken wire / netting' and earthing it?

Would you need to cover it with Aluminum (cooking ) foil ?

[Peace2all]

Hi Steven, Thanks for all the advice, it was very helpful. Seems silly to be considering protecting laptop when internet will most likely go down. But have to have music!!
Thanks Skeptikal with all your input it was good to see there are a few preventions we can try. The link that davefla73 posted was excellent and I am printing it now. Hi Tez, funny finding you here. Swanny what about lead x-ray suits doctors use?
In Australia lots of homes also have a steel Colorbond roof, timber floors, can anyone confirm the if our electricity is grounded?

WHAT THE??? As I am writing this reply, I mean RIGHT NOW. My son calls saying the whole of Melbourne City, lights, power, streets, shops everything went totally off.... Just then hubby and kids return from city... We live in hills, I said in greeting "Lucky your back the whole city is in blackout" When youngest replied - Yeah I just saw big blue flash in sky!

[Swanny]

Yea I want to keep some electrics alive like my ipod etc just to stop me from getting too bored if everything goes down, and I must have music :band:

Peace2all you definately have a earthed electric supply in your home, you can tell because some of your plugs have 3 pins.
I have lived in Oz in the past :)

Let us know about the blue flash in the sky :plane:

Yes, many houses around the planet has this ground network linking all electrical devices to the ground. It protects the user from electrical shock when you touch the casing, structure. But you need to make a conductivity test with a ohmmeter to really be sure that your electrical outlet is linked to earth ground. I'm saying this because many times, it is not. But remember you need a licensed electrician to work in the electrical network of your house.

Hehe, Looks like a transformer went rocket. If I may add this little note about your power source.

Shielding and grounding your devices with metal box, foil, etc... will protect your devices from outside EMP. But if you want to protect also your power source coming out from the outlet, and if you can afford it, you can buy a power source filter. It will filter all sort of "noise" coming from inside your electrical power to make sure you have a perfect sinusoidal wave (alternative 120V 50/60Hz).

Look for this type of filter for your electrical source: http://www.directindustry.com/prod/lcr-electronics/electric-power-filter-35095-214549.html there expensive, but you may find some more cheaper. Of course, you need a technician to install these.

Can you explain how this is done and what kind of gear is needed???

[Tez]

From memory, i think the Negative / Black is also linked or coupled to ground here in Oz at the meter box, maybe if there are any Electricians reading this they can confirm that or explain.

[Steven]

You need a multimeter, which has a voltmeter, ampmeter and ohmmeter. The ohmmeter will measure the resistance of a given conductor. If your resistance is near 0 ohm, then you are sure you have a continuity.

A multimeter isn't expensive here are some for home: http://www.sears.com/shc/s/p_10153_12605_03482139000P

Put the multimeter in ohmmeter position. You connect one test lead to a ground outlet (the round socket of the three on any outlet) and you connect the other lead test to your earth ground (which is the incoming water pipe in most houses). Measure near 0 ohm for a continuity. If what you measure has a high ohm value, like 10Mohms, then you are sure your ground outlet isn't really grounded.

Hello Tez. I'm from Canada and in Direct Current application, black wire are usually linked to reference point or ground. BUT NOT IN AC. In AC, it's the green wire or green/yellow, the white wire being the common return of the AC, not linked to the ground. The black wire is the "live" wire, don't ground it at any cost before measuring it with a voltmeter first. Of course, there are different color coding then North American, but be really sure before, an electrician advice is always the best to do.

Namaste, Steven

[IRKCOD]

Yes, it will make a very good protection, especially if you also cover it with aluminum foil. As long as it is physically grounded. Use #14 wire.

Namaste, Steven


Thanks Steven

Your advice is much appreciate

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?

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.

Yes, these metal boxes will make a perfect shield because it's all made of steel. But the paint on it act as an isolator, you don't want it to redirect EMP. Only make sure you file it to remove paint and dirt. Then you connect (weld with tin) the wire earth ground to it. Or buried into the ground.

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.

...ALL HOUSEHOLD WIRING AND REPAIRS MUST BE ONLY CARRIED OUT BY A LICENCED ELECTRICIAN...

Thank you very much about it Tez. A very good reminder indeed. I'll add it to edited posts of mine.

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/emp_and_faraday_cages.htm

Namaste, Steven

[Steven]

Yes, you don't want your components to be in contact with the shield (they can be in physical contact, but electrically isolated), only the metal framing, not the components.

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??

I like this idea because it's simple, not costing too much. It won't be as efficient as a Faraday cage, because for this, you will need to cover all the micro-wave with double layered aluminum foils and connect them to the metal casing of the micro-wave. A simple modification that will assure best result.

Thank you for this idea Swanny, Steven

[Swanny]

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 :original:

[Bleep!]

"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

Hi Bleep! You had me open my old books there.

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/login.jsp?url=/iel5/9020/28641/01282261.pdf?arnumber=1282261

Last, yes copper is a better conductor element, but it is more expensive and does oxide much faster.

Namaste, Steven

[Bleep!]

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.

This is a good idea as long as the transceiver is Insulated from the metal can. Even a simple metal lunchbox or metal cookie/chocolate box is good. Just don't forget the insulation.

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..

[Swanny]

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,

Why don't you just delete the thread if it's speculative. I work in this field and yes, antennas does concentrate EMP just like radio wave. Read the first post I made, the reason I brought the topic was about a future EMW of great strength coming from the sun according to Henry Deacon's somewhere in 2009.

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

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.

:original: How about old ovens, refrigerator or freezer would this work with emp?

[Bleep!]

Ovens, refrig, etc.?? Yes they would work.. especially if you replace the seals with copper braid or similar.

Where did Henry Deacon state the 2009 thing????
Surely he never said anything of the sort.
:original:

He may have hinted that a CME could happen.. but that is not a prediction. It was more like an example of another EMP source, wouldn't one think?



There really isn't anything else to say in this thread. We have experts and then we have experts. :original:

Why don't you just delete the thread if it's speculative. I work in this field and yes, antennas does concentrate EMP just like radio wave. Read the first post I made, the reason I brought the topic was about a future EMW of great strength coming from the sun according to Henry Deacon's somewhere in 2009.

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

Sorry.

I hope this misunderstanding is down to language barriers. First, it wasn't not a "moderator" comment. Secondly, it was not aimed at you though I happen not to agree with the way you have described the function of an antenna in this context. It might not be that you are wrong in your understanding, but the way I have understood your explanation.

I agree that RF prorogation is a complex subject so this is bound to happen. I cant write a book either - or even reference one at this stage. We cannot possibly get this right on the forum without expending huge amounts of time and words.

So please understand that I appreciate your work in this thread. I know (because you told me once before) that English is your third language and it is clearly obvious that this is a lot of work that you have done.

Speculation or not, this thread has managed to get an important message on the record.

On the technology, IMHO Bleep clarified the matter perfectly I have nothing to add either.

Namaste <-- first use on this forum from me, and meant it.

Hi Anchor. No worry. I understand your statement and admit I should have put "antenna" between quote. I was not referring to an emitting antenna, but rather a simple an inexpensive mean to catch and reflect EMP.

I will clarify it. When an EMP hits solid material, one part is absorb and another is reflected. All depending on the angle of the wave, 90 degree reflect the most, and the conductivity of the material. So, in installing antennas to the roof will not absorb and reflect all the wave, but will certainly diminish it's overall effect if it's grounded. I understand one can see it as not important in normal case, but as I said in the OP, it is not about normal condition. Because the ultimate shielding of one's house would be to cover the roof with grounded unpainted metal sheet. But, I didn't want to put it that way, because of the cost and complexity of this.

Lastly, the purpose of the post is to give simple, not costly advice to protect your electronic devices in case of strong EMP coming from the sun.

Here is something well written and totally conform to my experience: http://standeyo.com/News_Files/NBC/EMP.protection.html

To you Bleep! I appreciate your presence here. I am in no way pretending to be expert. And I do not question your statements, they are true and perfectly welcome. About Henry Deacon. I remember it was mention in one interview with Bill and Kerry. I can't remember which one, I have seen them all, but it was Bill who mentioned it to the person interviewed. Maybe someone here may remember which interview it was.

Namaste, Steven
