why don't EMP's disable themselves?

I was thinking recently about EMP's and how they disable electronic equipment and i realized that if an EMP generator is charged and fired with an electronic circuit doesn't that mean the EMP generator itself will be disabled?

Ok, well i wanna make some kind of simple EMP gun. Is that possible?

I saw some other forums that talked about it, and i would just want some that could disrupt something at close range, or something like that. I have heard of using a firecracker... but i don't think that i want to do that in public... xD maybe a disposable camera and some wire?? I have some enamel-covered solid-conductor copper wire, 30 gauge....

Creating a temporary EMP device

I'm new in this site. Anyhow, I want to create a EMP that can temporary disable electronic devices. I read some articles that producing one can  permanently destroy any electronic devices when activated.  I don't know if its real in the Dark Knight Rises where Bruce used a device to disable the cameras or even the lights and vehicles in the tunnel but I want one. The purpose of its creation is for killing some time and having experience in making one. Technically, I found a way to make a step by step temporary EMP however it does not show much like how much power produce or some voltage adjuster when you want to increase or decrease its potential.  In such case, if i happened to make one, how can I determine the radius of its effects? Does the voltage produce counts to determine its radius?

How do you make an Electro Magnetic Pulse Device? Answered

I would like to make and EMP device to blow an RFID. I understand that it is a capacitor and a coil.  And that you charge the capacitor up and then discharge it through the coil.  But what size and voltage should the capacitor be, and at what what voltage do you charge it and how thick does the wire need to be? Is it all about the voltage of the cap (12 volt or 400 volt)  or is it more about the size of the cap? Thanks

question about an emp and a electro thermal plasma expansion arc chamber.?

If i took the basic idea of using an emp that uses a flash camera and attached an electro thermal plasma expansion arc chamber mentioned here at instructables around the coil (of the emp replacing the epeac's coil)and instead used all the wires to connect to the capacitor and the other ends (not the coils ends) to the switch, with the coil seperated from the epac with insulation, with the nail in the middle of the coil what would happen? scientifically? anything?

Creating a handheld Emp device

Has anyone been able to create medium sized nonexplosive EMP generator? i recently purchased 4 oil capacitors each rated around 5.5KVDC and 32uF, from what i have learned, in order to create an EMP generator, you would need a to feed it a large amount of power in to  a heavy gauge magnetic coil. I believe my caps could do the trick. I will be charging them with a  ZVS driver coupled to a self wound ferrite transformer, then rectified. As for discharging i' will probably use a mechanical spark gap. I am hoping to create something like the shock pulse generators in amazing1.com, does my setup look feasible ?

Protection against EMP ...

Hi !Data :Let's say that I want to protect some important electronics devices against EMP.Let's say that they need to work 24/7 and that they are, thus, connected to an external source of power (electrical socket before EMP, and solar panel after EMP).Let's say that they need to emit and receive RF signals.Questions :1) As there are electrical connections with the exterior, a Faraday cage would be pointless, wouldn't it ?2) Would a solar panel survive to an EMP ?3) Is this possible to use the Faraday cage as an antenna for RF communication ? (I guess it's a stupid question as connecting the cage to the device would make the cage part of the device ...)4) Are thin and transparent gold foils enough to act as a Faraday cage ?_Edit : Interesting readings found thanks to the links Nachomahma provided :http://www.todaysengineer.org/2007/Sep/HEMP.asphttp://www.spectrum.ieee.org/archive/1543_Edit2 : an article about EMP protection.The first part is about EMP from nuclear bombs.

A powerful EMP generator, to disable (temporarily) stereos in my neighbors house.

Hey guys, I'm trying to build a portable EMP generator, which will be powerful enough to knock out (temporarily) my neighbors stereo (if he plays it on loud at midnight again). My setup is as follows: 8 330v 160uF Capacitors wired up in series. 8 330v charging circuits for the capacitors with their outputs in series wired to the capacitors through a switch. The 8 capacitors are wired up to a coil through a switch. The coil is made from 6 gauge wire (or a 1/16" copper strip) that is coiled 5 times. I would really appreciate any feedback because this is a fairly large undertaking for me, and i'm kind of nervous at working with over 2000v of electricity. Does anyone know if you can discharge a cpapcitor by throwing it into a swimming pool???

kick out lamps with emp

Hid lamps (sodium and halide) are used for outdoor lighting they are sensitive to momentary power interruptions (even the smallest ones that dont make computers reboot) and mechanical stress (like beating the electrical pole with the lamp). they extinguish and need some minutes to cool down before they strike again i thnk it should be possible to kick out the lamps with emp (electro magntic pulse) as well. how strong pulse is needed to affect this kind of lamp ? is it possible to pack such energy in a portable device ?

Any ways to block the EM waves from my solid state Tesla coil?

Hi guys, I'm working on a small solid state Tesla coil (Slayer exciter) and every time I test it, the internet router stops working and peoples don't really appreciate it when it happens. The router is about 25-40 feet away but my brother's computer is in the same room about 10 feet away but is connected with an Ethernet cable that might act as an antenna? I know that all the touch lamps in the house goes crazy so I really need to find a way to stop the EM waves to interfere with the electronics in the house. I thought about putting the coil in a earth grounded metal cage but have no idea if it would work and if there is any other ways to do it. Any help?

Can you charge a capacitor from the collapsing magnetic field of a coilgun? Answered

I was thinking about making a coilgun; not too powerful, only a small, compact (ish) version. Problem is, the capacitor takes a while to charge. What I was wondering is whether you return electricity from the collapsing magnetic field of the coil (after firing a shot) back to the capacitor, thus reducing charging time? And another thing; does a coilgun produce a weak EMP or something when it fires?

Can you help me with my mini E.M.P. generator design? Answered

Hello everyone! I am new here so tell me if I have broken any rules :) I am currently planning on bulding a handheld E.M.P. generator (it's dangerous, I know, sorry) that is capable of killing a small devices (e.g. a small camera) at close range ( - What is the bare minimum to kill such devices? - Does it normally take 90 secs to charge a 90uF bank to 2kV (using a DC boost converter)? I have never designed a high voltage charging circuit before so I don't really know if I'm doing things right. - Is my capacitor configuration good enough or does it need tweaking (e.g. more voltage)? - How do I protect my circuitry from getting blasted by the coil? - Is a single pulse sufficient? - What kind of switch should I use for high voltage? - Should I use lithium-ion batteries for supplying power? - Should I make the frame of the device out of metal? - Should I be using a DC boost converter for charging capacitors? If not, suggestion? - Should my coil have a little or a lot of inductance? Again, I am fully aware this has "Darwin Award" written all over, sorry about that, but I think this is safer than guessing around. Thank you for reading this! Looking forward to your responds!
