EMP device:
useful for damaging, crippling, and destroying electronics: i call it a high tech hammer. aka inducing a crapload of current in a digital circuit meant for maybe 5-12 volts.
you gotta understand that the effective range is maybe 6 inches... anyway:
you "acquire"(never say buy):
a disposable camera
a lightswitch
a crapload of high voltage and microfarad-age rated electrolytic capacitors(i use 3x 200v 330 microF) http://www.goldmine-elec-products.com/images/G13594B.jpg so you know what i am talking about.
and a new spool of insulated wire.
you will also need: a soldering iron, solder, a knife(plastic grip), a brain(some of us are hard pressed with this one)
procedure: first tool to use is your brain: you are screwing around with several hundred volts and could give yourself burns or even cardiac arrest (unlikely, I've gotten shocked before)BEWARE : http://farm1.static.flickr.com/182/436602164_0cda14d617.jpg
-proceed to find the capacitor in the disposable camera.(it should come apart easily) image: http://www.evosapien.com/robosapien-hack/marcus/assets/images/Flash_Circuit1.jpg
short it with your knife. image: http://farm1.static.flickr.com/182/436602164_0cda14d617.jpg
solder your capacitors in parallel ( if you don't know what a parallel circuit is then don't bother. you will end up hurting yourself) Make sure to use insulated wire for this. image of parallel-ness: http://www.angelfire.com/80s/sixmhz/images/cgkit07.jpg
use the remaining spool of wire, find the ends of the wire and attach one to one wire of the capacitor, and the other to the other wire, but with a light switch in between spool and capacitors. it should resemble the last image. try to figure out what to do to get the flash to charge this varies with cameras.
Use: charge your camera "flash" bring the coil near (not) your electronic device flip the switch.
how it works: This device will put several hundred amps at about 300v through the circuit for a short period of time. to short to blow up your wires. this generates a short impulse of a magnetic field. Experience says that this is bad for electronic devices often causing permanent damage. it causes severe damage by inducing way more voltage than the sensitive digital electronics in the electronic device are meant for.
If questioned: respond that its your science project (whatever) gauss gun. while it sucks for this task you can prove it by: place a piece of metal in one end of the spool, the center should be resting on the edge. (position is important) charge and activate your device. the magnetic field should pulse for long enough to accelerate your projectile to go about a yard( or five, depends on your luck)
How i came up with this: I found that my suck ass gauss gun project killed my watch Mad Then i was bored so i looked up serious EMP devices. and found this which is almost identical http://www.plans-kits.com/hvempbox.JPG oh and while your at that website: http://www.plans-kits.com/kits.html I am sure you can find some use for these devices...
i have no clue what it is intended for, but it has knocked out several watches,(hey they're cheap) for me, i found this after ym good one died. it will take out cameras. the idea is that it is nearly a dead short from the capacitor, which means that for a short mometn, you get an enourmous current. it was meant as a gauss gun adn works fine for both purposes.
Archived EMP
If you had talked about a huge capacitor battery feeding kilowatt radio tubes or even a magnetron and a decent directional antenna I might buy this, but a simple cap discharge into a coil will make for a melted wire coil but not much radiated RF.

If you create the EMP device found in the electronics section, you can walk up to a camera, stand out of its line of site, and the camera will "just die"... when they go to investigate, there is no physical damage, except overloaded internal components. Which could not otherwise be reasonably achieved in that short a period of time, as it would involve disasemmbling the camera, and shorting high voltage wires through it, implying a physical defecty in the camera, or a overload in the power supply. Also, walking up behind it would work just as well as making this point to them.

RESPONSE OF DEATH
RESPONSE OF DEATH: it does kill electronics as i have verified on a mp3 player and several watches. it creates a strong magnetic feild. although it wont make a wave, and is thus limited to several inches. The time that the current is sustained is short enough that the wire cannot heat up enough to melt. ahem: put it back d00d
Just to be clear Vov35 this device is intended to be a small spark gap transmitter? While it might generate an inductive voltage for a very short instant since you are talking capacitive discharge only this is a DC device. This gadget may make an impressive spark that would scare many people there is no way to assume that this would do any damage to anything without verification even at very close range. OTOH a direct shock into a video or data cable, even a power cable would probably kill most non-hardened electronics. Most of what people know about HERF and EMP comes from movies, the war on terror, and popular mechanics which all are motivated by an exciting fantasy story and not much by realistic physics. To my knowledge HERF weapons have never gotten beond DARPA testing without a nuclear explosive being involved, even the Gulf War I and Kosovo "EMP devices" turned out to be carbon ribbons dropped onto power substations.
