I am making an emp but I broke the Disposable camera's chip. So decided to make my own circuit, but it doesn't work. I am attaching my schematic. I know I am missing something, so please can anyone tell what it is? or just direct me to a simple schimatic? I have transistor... transformer and everything form the chip. I just don't know how to connect them.

Back in the late 50's the Heathkit company had a "build-it-yourself" radio kit based on the early TRF (tuned radio frequency) radio. For you younger guys, these radios were not superhetrodyne like our modern radios where one only has to rotate a single knob to change stations. With the TRF one had to tune each stage of amplification to the frequency of the desired radio station. At any rate, I bought one of these kits when I was in the Air Force and found, quite by accident, that if I tuned to a radio station that one of my buddies was listening to in the barracks, and then detuned slightly, I could jam his radio. Drove him nuts! But the best part came later when, on one weekend I looked out of the barracks window and, lo and behold! there was a guy washing his car while listening to his radio. Ha! So, I got out my trusty TRF, found the frequency the car radio was tuned to - AND JAMMED IT! Today, that guy is still wondering what the hell was wrong with that radio. I never tested at what range I could jam radio channels, but the car was a good 100 feet away. Now, this device will work with AM radios but not with FM, unfortunately (not without a lot of modification of the TRF).

Hello, my question is simple. If I connect about 3v to a microwave transformer and then to a coil, would it make a efficient EMP wave (shutoff a calculator). I know that I can use a disposable camera, I just am learning different ways to do it. (Sorry for the pic, done with my phone haha)

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.

Topic by ArcAngelZz 6 years ago | last reply 6 years ago
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?

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

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 ?

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 ?

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???

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?

Question by EthanY 2 years ago | last reply 1 year ago
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?

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 (<10cm). I got to the capacitor bank and wondered if 180J is enough for my needs? I also have some other questions (in no particular order): - 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!

This book has several high voltage gadgets to build, and if you are familiar with the "evil genius" series, presents a plethora of information on each one. There are 28 projects in all; and the front cover also says: * illustrated instructions & schematics * lists of materials & part suppliers * science & math behind each project The author is Bob Iannini The book cost me $24.95 (USA) new. It will cost around $3 to ship in the USA, so if anyone feels it is worth about $15-$18 that would be grand; otherwise, make a reasonable offer. I underlined one word in the introduction, but have made no other marks in the book. My reason for selling it is that I do not see any way in the foreseeable future, of me building any of this kind of project. Contact me by way of PM to work out the details if anyone wishes to purchase it. Thanks ahead of time.
