EMP Electro Magnetic Pulse or solar storm preparedness

[DoveDancing]

I thought the issues with solar flares is ground currents so it looks like your battery would be safer in the car with rubber tires than in the metal barrel on the ground...

[DoveDancing]

I was reading that a solar EMP does cause an E1 or E2 event that these are only from nuclear bomb explosions here on Earth...

[MIKON8ERISBACK]

Correction: You actually have a normal circuit breaker panel with a manual service disconnect switch that's fused. All I have is a 100 amp main breaker.

[MIKON8ERISBACK]

@MIKON8ERISBACK Combined with the two circuit breaker panels, one if a sub panel for my finished basement.

[bytmeh]

What a fat retard, notice how out of breath he gets at 6:00 just from talking??? Makes me sick, but not as sick as those scabs urghhh!!! Hey redneck quit pickin' yer scabs you sick fat fuck

[1023471965]

Question about putting your> electronics into the metal desk or metal cabinet. If the electronics make a -conductive-contact- with the metal desk, would not the desk just become a large -Antenna- for the EMP to enter the Electronics. (It wouldn't if desk is grounded)

I saw how the box for your emergency radio insulated the radio from the aluminum foil. Repeats be good = dangerous times now.>

The politicians & cronies be looting America as if they will NEVER be held accountable. What's up?

[Beowulfsonur]

If you have a car without electronic ignition then you should be alright. Older model vehicles do not have electronic ignitions...

[porsche558]

I believe it only takes just over 8 minutes for radiation from the sun to hit earth. Due to the fact that the distance between the sun and the Earth changes about 3% depending on where in the orbit Earth is. This would equate to about a + or - 15 second difference. Something tells me that wouldn't be enough lead time to "EMP proof" anything.

[dsarti1]

@porsche558 the light/radiation does not cause the emp. The CME does that takes up to 2 days

[glorytarget1]

I see you like cholula hot sauce...

[yadig2012]

LOL!

[mdredmond71]

Some of the information in this video is simply wrong and betrays a lack of understanding of EMP and basic physics. For example, you do NOT want to tie the negative and positive battery cables together on your car - or ground it. Electricity cannot flow in an open circuit. Likewise your battery, after being removed, does not need to be protected for the same reason.

Faraday cages for small electronics aren't a bad idea but probably aren't needed. Most important is to protect anything that

[alexbald12]

@mdredmond71 Would a car stand a better chance in an aluminum shed?

My impression is that semiconductors and anything with a coil of wires are at risk.

How much sheilding is enough to protect computers?

How about solar panels?

[L2design]

Terrorists? you mean our government.. thanks for the video :D

[Beowulfsonur]

@L2design...True that. Sad but right on target.

[smonahan67]

LMAO Isn't the car/truck the metal case around the battery..?!?!?!

[dsarti1]

@smonahan67 LMAO the car is not a complete enclosure.. there are many holes just like your brain

[duf101101]

Batteries still work after EMP. See Discover Channel's "Taurus gets Zapped by EMP"

[darthvader5300]

Just simply build a steel-reinforced conductive concrete structure which is grounded to the ground and insulate the inside with a non-conductive material which is strong enough to support any internal buildings and industrial structures. And anything electricals and electronics inside will be inside a steel box like structure (grounded too) linned with a ceramic insulator. And everything will be mounted on springs or hanging from springs to make them shock mounted against any nuclear detonation

[minrlwtr]

The Book Preppers Road March was a interesting fictional account of someone surviving after a solar storm hit and wiped out most technology

[psilocybinist]

My body has electricitty in it, do i gotta wrap up in aluminum foil too?

[psilocybinist]

So can you ground out the breaker if it isn't ancient?

[johnny102marvin]

Nuclear Power Plants are not inside a faraday cage. The electrical surge will follow transmission lines and go right into the electrical wiring and computers of the nuclear power plant. This instant frying of the electrical structure of the power plant will prevent the computers from initiating safety shutdown procedures such as bringing down the protective shields and kicking in the diesel generators to run the water pumps. This would result in an instant meltdown - WORLD RADIATION.

[fastacker2]

@johnny102marvin I am pretty sure the carbon rods are held in the run position by solenoids. When the power fails to the solenoids, giant springs ram them to the crash stop position. fail safe position. I think you underestimate the designers of nuclear power plants just a little. At least the ones in the US. But I'm no expert.

[TangAppy]

This is why we NEED rednecks. I effing love them when it comes to survival stuff. lol (not saying it in a bad way)

[KnightGadiel]

everyone is gonna get sea sick lol i love the videos that this guy does, info + humor

[level3offender]

thank god for rednecks :)

[Lostfalls]

I just want to say thanks for your knowledge and opinions, I'm a newbie and want to learn so this stuff really helps. Thanks for doing this when so many others are content to sit back leave rotten comments for others.

PS - this is a really good thing you're doing let others call you whatever but you don't have to call yourself names, every time you do my heart hurts a bit - so knock it off you're so much better than that. :-)

[fatlarry1962]

If only it was really that easy..But it is not.

[wcd47]

Get an old 66Chevy and you're good to go...I got one....

[sadieblooming]

The storm is scheduled to come in continuous consecutive wave. During your unwrap of your radio, it can be destroyed. You may need a way to know when the storm has passed. Let me know if you do. It may last several months. Make sure to buy radios that run on 12V. Since car batteries will surely survive.

[sadieblooming]

I would make sure my electronics are airtight. So I would take the radio out of the box and wrap the radio several times with foil and plastic bag it then vacuum seal it. On the other hand, in a solar radiation storm, everything could fry, caged or not, unless it's under many feet of concrete.

[sadieblooming]

The car battery is very rugged. I believe it doesn't need protection. But your car electronics will need protection. Instead, buy a emp hardened diesel truck.

[friedfish1982]

What you are talking about here Sir is called a faraday cage

[w2aiq]

A nuclear device itself does not have a very strong EMP effect over even a mile or two

BUT...... a specific (non-nuclear) EMP device could be made / designed to have a very far and wide reach.

[AridSea]

300 miles over the US wouldnt do anything, fyi, EMP blasts from nukes end at around 120 KM.. good vid tho

[dsarti1]

@AridSea And how do you know this? The Dept of energy says otherwise

[fastacker2]

@AridSea I think nukes can be specifically designed to produce more EMP if that is the enemy's objective.

they also come is widely different sizes.Tzar bomba is many many times larger than the ones used in WWII. quoting a fixed range for EMP effects from a nuke is simply not correct. .

[fearNotone]

great vid, but I don't believe any current preparedness will prevent the waves from de-activating any technological things. When the major waves begins to hit earth, the rest is history as far as technology i think. The sun is just to massive and all it's energy is not only coming from the sun itself, but from outer stars as well and the earth itself.

[doobing]

is there any thing you can do and still drive the car Im just worried that we wont see it coming and no time to prepare

[eyeblazeblunts]

preparedness

[mattmancube]

you might want to mention that whatever you put in your metal boxes/washing machines/freezers etc.... such as laptop or any other electronic device is NOT directly touching the metal enclosure you're putting if in.

[4siempre1]

ALL WE UNDERSTAND THAT YOUR ROOSTER SINGS VERY WELL

[BowenDesignWorks]

We are taking advice from someone who cant press the PAUSE Button on a vdieo Camera. Here is a TIP to "keep it short" AT 3:22 Press PAUSE then REC at 3:40

[kahonwes]

just curios could you just toss some of this stuff in a huge metal ammo can, I mean they hold ammo why not a radio

[alookoutiger]

You are doing a great service to most of the American people. I hope they will stop for a second and listen. God bless America. Keep on educating us. Great job.

[adrastea99]

A solar maximum has nothing to do with EMP

[itsadeadmansparty]

@adrastea99 how so, would if a solar flare come to earth in high magnitude not cause electrical devices and micro circuitry to crash or electro static pulse? if not why then?

[adrastea99]

@itsadeadmansparty

Son, do you want to rephrase that sentence because it's pretty confusing

What I said is that a solar maximum has nothing to do with EMP or flares, but the amount of light put out by the sun

[itsadeadmansparty]

@adrastea99 So you are saying when the solar maximum occurs next it will not harm earth's micro electronics? like an emp? if so why not?

[adrastea99]

@itsadeadmansparty

I am saying that EMPs and solar flares are not related to solar min/max, we've had flares during minimums and maximums as well

They are two separate things

[dellguru1]

was the tin foil next to your laptop for a hat?

kidding. As you should already know, a powerful EMP would fry most electronics even if they are grounded. Also, there was a documented case of lightning hitting a tree, and the jolt was able to travel under ground and electrocute a few bystanders. This means that grounding is not only not 100% safe, but can carry energy. Also, if your idea does work, do you really want to be the only 'Have' in a world of 'Have Nots'? I sure wouldn't want to be.

[azis1100]

emp is vastly over rated, anything off grid will most likely work when plugged in. think 1990 and surge protectors...will be about the extent of it.

[fastacker2]

For vehicle protection, maybe consider buying a spare ECM module and storing that in one of your metal Faraday cages (gunsafe or other steel cabinet). However, I think the paint on the door must be removed to create electrical contact around the endges of the door with the gun cabinet. Also, the electronics should sit on an insulator (like in a cardboard box). But who really knows?

[banetek]

I am glad to see you are taking the threat seriously, and are trying to assist others in preparing themselves. However, all of your efforts will be rendered ineffective. Unfortunately, the problem is the silicon board components and other electronics within your car (& elsewhere) will burn out! The EMP will cause high voltage arcing across the boards from component to component; regardless if you disconnect power or is grounded.

Also, you must use brass mesh; aluminum foil will NOT work!

[biguglygadgie]

iam banking on putting all my radios car alternator and batteries in to a big lead box. and if i had the money i would cover the shed in lead and drive my vehical in it. they say lead is the best.

[whizbangmusicwerks]

my only concern about this is the ECM on the truck. There are a lot of wires (GM TBI) going to a lot of sensors that would get a current induced across them, wiping out the ECM. Personally, i would disconnect, remove, and shield the ECM

[bicrastAK]

whats with that guys arm? lol at 8.00

[deckdrive]

save your vehicle...How are you going to pump gas into it? No more gas stations. Save your home's electric? No more power company. Once people realize you are in your house and may have supplies the gangs will overtake you and kill you, raping your wife first. There will be no other option but to walk (or drive your saved vehicle) to a desolate place with abundant food and water sources. Then, all you can do is hope you survive. And make it out to see society restart itself all over again.

[ThndersRage]

@deckdrive

You think this guy can not defend himself? After the Gang loses a few men they will flee for easier targets. They may return of course and likely so, but then our man here will be expecting them and have prepped accordingly.

Who's to say he has not already? Have you seen this guys area? Its all flat. No one is coming near without being seen and he owns a scoped rifle or two.Not to hard to figure out what to do if he spots them far off and this is a WROL or SHTF type scenario.

[Y2R4U]

HE IS CORRECT IN HIS CRUDE WAY. BUT P.S..... OLD TUBE RADIOS BEFORE THE 1960's WOULD BE A GOOD INVESTMENT. THEIR CIRCUITS SHOULD BE SAFE.

[jamesinky]

What would work better than your car port would be a shipping container thats grounded. Good video! I have my gunsafe grounded with an old laptop in there that can run off 12V. Aluminum foil by itself wont work. to make a fariday cage to protect electronics the shield MUST be grounded to work.

[Angyal269]

An advice about how to test if your EMP shielding works properly: put your cellphone in there and try to ring it from landline. If it rings than you are doing something wrong.

[behindeverybush1]

And I would have had something to play with if it wasn't so little. Mine looks like an acorn nestled in a brillo pad. And when I' not really aroused it's small. Now, where did I put those tweezers? I need to go wee wee.

[behindeverybush1]

I have no comment on emp because I don't understand it but them overalls your wearing reminded me of when I was a kid at Cristmas. My parents asked me what I wanted for Cristmas and after a lot of thinking I said I wanted something to wear and something to play with. So at Cristmas they got me a pair of overalls and cut the bottom out of the pockets. Yes, I'm from oklahoma.

[gavinsstuff]

surely you dont need to wrap radios etc in foil as long as the batteries are removed and no charge is flowing

[SidneyBou]

I believe to make damed shure that EMP does not get in the tin foil should be rolled at connection points. Batteries should not suffer unless connected to wires like electric fences or AC wireing. The oil distributator and point ignition will not suffer but the new system will go down. Maybe if parked under a grounded metel roof not sure. Your desk may work but a great deal of pulse will sneek through the draw gaps.

[thehilitereel]

I think its useless trying to salvage these things, because there really wouldn't be any way for communication for months or weeks anyway. No one really knows how a giant solar storm will affect us anyway, I think the satellites would probably just burn up anyway, powered on or off.

[ThndersRage]

@thehilitereel

You are probably right but hand-held computers will still be useful if you have a means to charge their batteries.

After I am done here I will be placing mine in something shielded, I have many PDFs on it that will be useful reference material which I have no books for.

[themeaningoflife38]

china has an anti sattelite weapon.they also have a new cruise missle designed to destroy our aircraft carriers.

[trento7o8]

All great ideas but it fries EVERYTHING you need to replace your dash gauge things then replace your gas regulator thing anything that works on power so basically we'll be shit outta luck

[ThndersRage]

@trento7o8

Correction, It fries everything that is not shielded. If shielded properly it is not going to fry. For instance I put my Ipaq or whatever in a sealed iron box, it is not going to fry.

EMP is cool an all but it is not un-beatable.

[RYANSCHLESINGER]

fuck beefyhaze,pilotman and all other dumb asses

[peticopower]

Sorry but grounding is very complicated for an EMP or solar flare. Most grounding acts as an antenna for the pulse. Copper screening and alum screening works best.

[Hiberniason]

Great vid, dsarti1. You're a great American.

[MrGreatLakesBuffalo]

What do you think about China attacking us in the years ahead. They'd set off an emp and before you know it...we have these folks dropping from our skies. Any thoughts on the very populated nation of China making a grab for the US and our farm land?

[ThndersRage]

@MrGreatLakesBuffalo

Something about a gun behind every blade of grass comes to mind.

Unless things have changed significantly from last I knew China, while they have significantly upgraded tech, does not have the ability to project serious amounts of force overseas. Not nearly enough to subdue the militia, what military is at home or the people who own firearms.

But anyways I think this is a non-issue because we buy most of their garbage. They take us out who is gonna buy their cheep garbage?

[2346]

the solar maximum is suppose to happen next year 2011 sometime in novemember

[jplerwill]

An unplugged microwave oven should work well as a small shield as well

[agun17]

The tinfoil works indeed. Wrap your cell phone in it and it wont receive calls.

[auraofgloom]

@agun17

You would need to insulate the phone from the foil for that to work. I've seen folks talk about using ziplocks. dont know enough to know if it would work.

[agun17]

@auraofgloom

Look, take your cell phone, wrap it in tinfoil without leaving gaps and try to make a call. I've done this and I know it works so don't tell it doesn't because that's just being dumb.

[auraofgloom]

@agun17

I am not saying that it doesnt work, I am saying that a)if the phone is not insulated from the foil then the charge may run into the phone by direct conduction.

If I wrap myself in tin foil and touch a power line will I be OK? Or would that be kinda dumb because the juice flow through me into the ground and kill me? If I wear insulation between me and the foil would I be more likly to live?

I used to work with 750 volt DC current and have an idea of what I'm taking about

[SidneyBou]

@auraofgloom I once got shock from 400 votes. Probably droped the votage somewhat. (modulator on a 200 watt transmitter before transisters overtook the field) Did you ever get hit by the 750 volts?

[auraofgloom]

@SidneyBou

nope, but one time I was a dumbo and had keys on a chain round my neck and as I bent down to ck the line with an egg box (lights up if theres juice) and said keys dropped down as I jumped up!

LOL Scared the #$%p out of me!!

The railway line has almost DC to draw- one kid playing on the track had it burn right through his leg to the bone. ICK, smells like bacon :(

Onece i got mildly zapped through water spray-felt like i'd hit my funny bone but scared me too.

[auraofgloom]

@agun17

Also remember that wrapping your phone blocks radio waves at a minute level- would just wrapping a cell phone in tin foil work if your phone was struck by lightening?

The idea of foil wrapping electrics is to make a path for the juice around the sensitive parts-like a hat brim diverts the rain off your head- if you dont insulate the stuff from the foil the juice will flow right through it- kind like having a hat that sucks the water into it and onto your head.

[ZionistWorldOrder]

I believe the ratiation will first be absorbed by metals in the electronics or non electronic metal parts near the circuit and THEN result in a buildup of charge and then discharge. I would respectfully advise to park any vehicle or device such as solar chargers &whatnot ;) under a garage augmented with a faraday cage perhaps & metal panels such as led even.. Smaller boxes for smaller items like torches & radios. Don't mind the haters, able men & women such as yourself are national treasures.

[lilacmoon68]

I really enjoy watching your vids.. Don't pay any attention to all the negatve comments. there are some of us who are trying to learn something new! Keep on makin' your vids.

[Popsicle22754]

good luck brother. thats all i have to say.

[BeefyHaze]

your a dumb ass peraniod idot that shit wouldent work i would have my gun and take what i need...

[dsarti1]

@BeefyHaze LOL lots of us have guns too...

[jasonmushersee]

@dsarti1 I to have been preparing. As long as the technology exists it could happen in my life. I got a chest freezer (container box) for my generator.

[banetek]

I am glad to see you are taking the threat seriously, and are trying to assist others in preparing themselves. However, all of your efforts will be rendered ineffective. Unfortunately, the problem is the silicon board components and other electronics within your car (& elsewhere) will burn out! The EMP will cause high voltage arcing across the boards from component to component; regardless if you disconnect power or is grounded.

[kennyz6979]

@dsarti1  yep

[jaylove1776]

@dsarti1 but do you have clean water and food

[fuelfreak108]

@BeefyHaze - good luck with that one. you'll most likely be encountering some "resistance" haha

[Hiberniason]

@BeefyHaze you're the first one we'll put in a box brother. You think we're just going to let folks like you run amok? You listen to this man. He's got good ideas. And these things we'll work... What won't work is "I would have my gun and take what I need" because guys like me will grind guys like you into powder... I am my brother's keep and I am the good shepard. I will not let anything come to harm my brethren...

[ShmeegleSon]

@BeefyHaze look whos the dumbass, you cant even spell right, oh ya i forgot also your the only one with a gun

[boonedawg68]

@BeefyHaze Calling someone a dumbass then misspelling 3 words in the same sentence..........priceless.

[48stevemr]

@BeefyHaze

Sorry, did you say HE was a dumbass? You, the thick bastard who can't even spell !  We shall see who survives a cme/emp and i'm pretty sure that between you and him it wouldn't be a turd buglar like you who comes through the other side of such an 'enevitable' very very near event.. TIT !

[timds6]

if you cover the battery it wont do shit... EMP's attack "more confusing" circuit boards like a computer, or ignition system in a car. It wouldnt affect a flashlight or the power windows in your car because those are "simple circuits".

[MacsterTech]

Not to undermind you but if the surge has a place to go, which is what causes the burout, and it flows through your house it will fry your equipment in the process. The way to protect is to provide a quick way to ground, not all the way around.

Also the aluminum foil will conduct and that does work. But the high voltages will spark out of the foil. It does work but the voltages are just too high. Your info is still correct though.

[pilotman123321]

that wont work the emp f-76-mzxe field will penotrat the steel and it is not like lightning u dumb ass juw

[dsarti1]

thank you for your wonderful comment. The EMP destroys electronics by static discharge. If the electronic are shielded and grounded the static will seek ground thank you very much

[stalkersas]

@dsarti1 emb is verry dificult to defend against, because you need both magnetic and electric shield. if the magnetic pulse pases an electronic device, grounding it is worthless, because there will be too much power generated in wires and conections between components. shorting the wires where you conect the battery is worse, because you create a circuit.

[wompol]

@dsarti1 you might want to consider adding non-conductive insulation between your actual electronics and the drawers of your metal desks (or washing machine, filing cabinet, etc) to avoid EMPs from running through en route, per most Faraday cage recommendations. Good tips. Thanks.

[ShmeegleSon]

@pilotman123321 you cant even spell right fucking retard

[CONSTRINGACY]

terrorist you mean Freedom fighter dont you?Im mean to them you he terrorist!

[pshinspections]

You have to ground each farraday cage. It is not enough to simply touch the ground. Proper grounding means attaching them to a 6-foot grounding rod into the ground. Again, simply touching the metal case will not help.

[dsarti1]

6ft grounding rod is what the book says is best but a rusty fence post will work and is better than nothing

[nkey01]

thank you for the advice.

[godsend420]

high altitude nukes create emp or the transformers on telephone poles way less localized but great points just remember the top 5 feet of soil is bad in a dense fallout ☆☆☆☆☆

[Michigansnowpony]

Stupid question: Would smaller batteries that one has stored be okay without protection? (You know, the AA's, C's, D's for flashlights and stuff.)

Also, any tips how to protect a large, home generator that isn't mobile? Thanks.

[dsarti1]

size is irelivent and batterys are pretty safe but if possable I would sheild all stored electronic equipment if storing batteries make sure they are in a NON conductive container first. There are little things you can do to increse your odds in electro storm or emp simply grounding your tin roof and making sure your lightning rods are in working order. did you follow the link for the chicken wire faraday cage?

[pshinspections]

Chicken wire is only semi-conductive. Copper is better.

[Michigansnowpony]

No, I missed the link. Will follow up with that. Thanks!

[minrlwtr]

The old gas trucks that filled the tanks at the service stations used to drop a chain that was hooked to the bumper on the ground for static electricty reasons i guess, wonder if dropping one from your trailer hitch would work for emp?

[dsarti1]

anything you do to give the static charge a easy path to ground will help...Just playing the odds. not a grantee but will put percentages in your favor

[MadBadVoodo]

Interesting stuff...

[johnny102marvin]

PART 3 - Actually, the adult bicycle might be a better vehicle for older people or for people who cannot ride the typical 2 wheeler. You can pack more supplies onto an adult tricycle. People that tried to flee Hurricaine Katrina before the storm hit found themselves stranded on I.H. 10 bumper to bumper cars going no where. There were no restrooms, no restaurants, no food, no water. You can store the bikes that break down into 3 parts easily in the trunk of your car, with space to spare.

[MadBadVoodo]

★★★★★

[johnny102marvin]

PART - 2 - The subject of the use of bicycles for transportation after a world wide disaster is a neglected topic in preparedness discussions. During a disaster such as EMB, solar maximum, huge regional earthquake or whatever...the streets of large cities are going to be clogged with cars. Take LA, New York for example, in those cities you will only have two ways to get out of the chaos and that is either by walking or riding a bicycle. Can you do a video on

cross country bicycles?

[dsarti1]

I have a turing chainless shaft drive bike but I am not a bycler so dont look to me for that video.. Hopefully I will find a doctor to accept my insurance and after surgery I will be able to ride the bike

[johnny102marvin]

Dave, you gave an excellent presentation of things we could do to protect our electronics from a huge solar flare or from an EMP attack. 5 stars...

In the event that we did lose our cars because of the destruction of computer chips in our cars, there is always the use of a bicycle or horses to get around.

People living in large cities should have bicycles as a back up for getting "Out Of Dodge" as we saw in the movie "Day After Armegeddon".

[liabatud67]

Have you seen the movies "2012", "The Road" or "The Book of Eli" yet??

[vention4wh]

Awesome vid! This sort of thing should be prepared for and I've taken some measures to get ready as well. If i've heard correctly though, EMPs are most destructive to fine circuitry rather than big things like car batteries. Can't hurt to be safe though.

One Faraday cage that you forgot to mention, one that's in nearly every home in the US, and that's a microwave oven. If your house is grounded that would be the safest spot in the house for your electronics.

[dsarti1]

All homes are grounded but unless it is a metal frameing and aluminum siding .. However if building a new home you could put chicken wire over all the shethingand ground that

[vention4wh]

2.

The microwave oven uses it's Faraday cage every day to keep you from frying when you cook something, so it provides top notch EMP protection, especially if you have your home grounded the way you do.

Pulling your breakers is great because otherwise the entire power grid will collect that EMP energy and funnel it right into your home. I imagine it could not only fry your laptop but it might even turn into a small bomb if that much power hits it.

[crabtrap]

vention4wh,you stole my idea! we use a few old microwave ovens (direct grounded using all3 pigtail leads wired together and grded to earth, not plugged in) to store radios ,LED flashlights and other sensitive gear .

WHICH REMINDS ME ;LED FLASHLIGHTS ARE SENSITIVE TO EMPs!!! so store afew of the incandecent flashlights too

[vention4wh]

crabtrap

Awesome that you use a microwave that way! I think I'll start looking for cheap used microwaves. I know just where to ground it.

Are you sure LED flashlights are vulnerable to EMP? I had the idea that only complex electronics are vulnerable. But a single huge LED? My flashlights are 3 watt specials that I bought for 12 bucks each. They don't have any complex electronics in them.

My headlight however has multiple settings, heat sensors for the LED's and voltage monitors so it's toast.

[dsarti1]

Don't forget that CREE and Luxeon have a rather large ESD diode inside, that would greatly help to clamp that pulse from destroying the die. Usually this ESD diode is rated for 2,000 Volts. Also, the die is mounted above a "ground plane", which has capacitance, which will further help reduce the effects of the pulse.

EMP pulses are short, in the order of 100 billionths of a second, dropping to half amplitude within 200 billionths of a second,

[val5214]

Awesome vid. Best one so far. It surely is refreshing to see something informative and helpful such as this after being frustrated looking at all the waste-of-time b.s. vids and websites from those who are 'just tryin to help' - on this subject. Again, wonderful video. If only their were more like this.

[dsarti1]

pt2

There are two major modes for EMP to get into equipment:

-Front Door Coupling occurs typically when power from a electromagnetic weapon is coupled into an antenna associated with radar or communications equipment. The antenna subsystem is designed to couple power in and out of the equipment, and thus provides an efficient path for the power flow from the electromagnetic weapon to enter the equipment and cause damage.

[dsarti1]

PT 3

Back Door Coupling occurs when the electromagnetic field from a weapon produces large transient currents (termed spikes, when produced by a low frequency weapon ) or electrical standing waves (when produced by a HPM weapon) on fixed electrical wiring and cables interconnecting equipment, or providing connections to mains power or the telephone network . Equipment connected to exposed cables or wiring will experience either high voltage transient spikes or standing waves

[dsarti1]

pt 4

which can damage power supplies and communications interfaces if these are not hardened. Moreover, should the transient penetrate into the equipment, damage can be done to other devices inside.

Notice how both modes for a significant amount of the pulse to get in, are mainly antennas and wiring.

[crabtrap]

i'sure some of the older LED cheapy type flashlights my be fine but any halfway decent on will have a micro circuit for differant powersettings/blinking etc (the blinking leds alone have a tiny chip in them . so just beware and protect them . look for microwaves in the trash,i see them all the time,ecspecially those big 1980's ones you can park a car in almost LOL

[19ADC67]

by the way, you said you learned all this from air force and books. I have been trying to get into electronics as a hobby. I have read a lot of terrible books that only scratch the surface of it. very frustrating. None of them show you HOW to build circuits and the METHODS and WHY a particular circuit is made in that way. Do you have any suggestions on books? websites? thanks
