Picture of EMP generator
To make a EMP generator you will need:
A disposibul camera
alot of copper wire (the thiner the better)
A switch.

Step 1: Making the coil

Picture of Making the coil
You need to make a coil of wire about 10cm wide, you can do this by wrapping the wire around a circal object like a drink bottle. When winding go for thickness not whith, the thicker the coil the better. When finish wrapping slide it off the circal object and tape it up so it looks neat. Make shore to leave wire to connect it to your switch and power sorce. You should have a nice ring.

Step 2: The disposibul camera

Picture of The disposibul camera
Get a disposibul camera with a flash, take the charging circet out of the case. DON'T SHOCK YOUR SELF. The charging circet has a 330volt capasitor and if it's charged it will hurt. To discharge the capasitor touch the two wires conecting to a black cinider(the capasitor) with a screw driver, it should put out a shower of sparks. Make shore you take out the batteries.

Step 3: Assembly

Picture of Assembly
Attach one of the wires coming off the coil to the switch and the other to one of the wires going into the capacitor. Get a wire going from the switch to the other wire going into the capasitor. When your done charge up the capasitor and when it's charged switch the switch and it will creat an EMP. It should be able to knock out calculators at close range. If not improve the coil with more layers of wire or attach extra capasitors onto the charging circet.

What can I do for longer range of pulse ? And how can I calculate (not exacly for general) the range or pulse force ?

Immediate failure resulting from ESD exposure is easily determined: the device no longer works.

A failed component can be removed from the subassembly in which it is installed,representing no further reliability risk to the system.

Not all devices exposed to ESD, however, fail immediately. Unfortunately, there is little data dealing with the long-term reliability of devices that have survived ESD exposure. Some experts, however, suggest that two to five devices are degraded for every one that fails. Available data indicates that latent failures can occur in both bipolar and MOS chips and that there is no direct relationship between the susceptibility of a device to catastrophic failure and its susceptibility to latent failure.

Damage can manifest itself in one of two primary mechanisms: •Shortened lifetime, a possible cause of many infant mortality failures seen during burn-in

•Electrical performance shifts, many of which can cause the device to fail electrical limit tests

Failure Mechanisms

Destructive voltages or currents from an ESD event can result in device failure because of thermal fatigue or dielectric breakdown.

MOS transistors normally are constructed with an oxide layer between the gate conductor and the source-drain channel region.

Bipolar transistor construction is less susceptible to ESD damage because the oxide is used only for surface insulation.

Oxide thickness is the primary factor in MOS ruggedness. A thin oxide is more susceptible to electrostatic punch-through, which results in a permanent low-resistance short-circuit through the oxide. Where pinholes or other weaknesses exist in the oxide, damage is possible at a lower charge level.

Semiconductor manufacturers have reduced oxide thickness as they have reduced device size. This trend has resulted in a significant increase in sensitivity to ESD damage.

Detecting an ESD failure in a complex device can present a significant challenge for quality control engineers. For example, erasable programmable read-only memory (EPROM) chips use oxide layers less than 100 angstroms, making them susceptible to single-cell defects that can remain undetected until the damaged cell itself is addressed. An electrostatic charge small enough that it does not result in oxide breakdown still can cause lattice damage in the oxide, lowering its ability to withstand subsequent ESD exposure.

A weakened lattice will have a lower breakdown threshold voltage.

ESD Failure Modes Low-power semiconductors are particularly vulnerable to damage from electrostatic discharges (ESDs). MOS devices tend to be more vulnerable than other components. The gate of a MOS transistor is especially sensitive to electrical overstress. Application of excessive voltage can exceed the dielectric standoff voltage of the chip structure and punch through the oxide, forming a permanent path from the gate to the semiconductor below.

An ESD pulse of 25 kV usually is sufficient to rupture the gate oxide. The scaling of device geometry that occurs with large-scale integrated (LSI) or very large-scale integrated (VLSI) components complicates this problem. The degree of damage caused by electrostatic discharge is a function of the following parameters:

Size of the charge, determined by the capacitance of the charged object

Rate at which the charge is dissipated, determined by the resistance into which it is discharged.

I would like to have a very small emp device. I am willing to pay for all the expenses. Please let me know if someone can help.

dude just make one the tools and materials are very cheap and easy to use.

I'm working on one were the parts are easy for anyone to get. And also to assemble.

does it work to incapacitate human being or induce current in human body?

it could theoretically incapacitate a human but you would need alot of power.

Not quite, but it -does- screw up pacemakers

I read in another article that a thick wire is better than a thin wire and to wrap round a thin iron tube. It also said try to cover the whole length of the iron tube.
ReploidX9 ewcrew7 months ago

An iron core would actually help quite a bit, it amps the strength of the magnetic field

a human arm works also but not as well the emp i made used 16 awg wire wrapped around a 3.5" cylinder and i put the coil over my arm like a gauntlet.

ReploidX9 ewcrew7 months ago

Forgot to mention, the thickness of the wire should be adjusted depending on how much current you plan on running through it at once, you don't want it overheating and melting/burning.

I didn't read the entire thing, but I did notice something.

Did you use legos for the convenience of it?

What is a better substitute?

insulated clothes hanger wire.

Two things:

1) That won't put out an EMP, it's not even an electromagnet.

2) Your spelling is awful

3) My maths is awful

If it isn't a emp then why dose it Work and behave exactly like one?
ReploidX9 Jewson7 months ago

You can't physically materialise a pulse dude, you're just making something that creates said pulse.

do you even know what an emp is?

Electro-Magnetic Pulse

You have to vary the power to the coil. It has to go on and of to produce AC. Kinda.

If you read the text, it says there's a capacitor hooked up to the coil. Doing so creates a flywheel circuit, which produces alternating current. It probably wouldn't be wise to use an electrolyic capacitor in this thing; it might get ruined.

hey the disposable camera's ccircit u used that could be replaced by a mosquitoe zappers circit
Perfect for school. You know knocking calculators out during class. =D
Testing relays in a circuit without powering up. It also biases turns on semiconductor components without power up. Used as a test tool for traffic light and high power industrial equipment. When testing with power check circuits controlled by relays or component by activating them manual. Also check mechanisms in soda change and casino devices.

If I'm going to add more capacitors to it, should I do it in parallel or in series?
Capacitor should be hooked up in parallel to increase the capacitance. Series to decrease. eg: two 10 ohm resistor in parallel = 5. In series two 10 ohms 20 ohm.
Cap 10 microfared parallel =20 microfarred In series = 10 microfared.
if you want more capacitance (and thus a stronger pulse) attach in parralel. if you want more voltage tolerance (and thus a safer capacitor) use series.
Kind of looks and acts more like a degaussing coil. This is also how energy is created. If you take and spin a magnet inside of your coils of wire, it will produce electricity on the ends of the wire
It is kinda. Your correct

what i have seen is tat when EMP is created the device in its range are permanently damaged .....nw when u say knock off calculator is tat damaged permanently?

also what charge is supplied to this coil AC - DC ? and to what amount?
DC but it needs to be energized and de energized. 18-37 volts. You Have to experiment. No equipment should return back to normal.
Does your H key work?
an EMP will not permanently damage an electrical device. It may be momentarily attracted to it, but there is no evidence for them being able to destroy circuits.
actually there is, during the cold war when the united states was doing testing of nuclear weapons in the pacific the accidentally misjudged the strength of the weapon and found that the electrical systems in Hawaii were overloaded with thousands of volts melting their home appliances and causing damage to the island's infrastructure.

nuclear EMPs usually have a very small range compared to it's conventional blast, at surface level the conventional blast wave not only outpaces the EMP but it also envelopes it. however as you start detonating the nuclear weapon higher in the atmosphere you start seeing the range of the EMP increasing. 1 mile in the atmosphere could take out an entire state the size of say Kentucky. 2 miles could take out a good section of the breadbasket. 3 miles could take out anything not in a faraday cage or anything that isn't properly grounded device.

what happens with a nuclear emp is that the gamma rays "knock" electrons out of the air ionizing it and this forms a blast wave composed of the "knocked" electrons. this wave induces high voltages and currents in microchips as well as overloading the pigtails on telephone poles.

*spoiler* as a post script note: this is the concept that they were showing in call of duty modern warfare 2 when they blew up the space station.

however what they don't tell you is that properly grounding any circuit to earth will save most any circuit from an emp and anything with a microchip can be saved by "grounding" it to a Faraday cage that is grounded.

any transformer or coil will produce an emp, just like sparks will. if you hold up a radio to the light switch as you flick it on and off you can hear it's emp on a quiet station. the reason why electronics aren't affected wholesale by light switches is because the strength of the emp just isn't there. same with a coil like this, the energy is stored very briefly in the big huge electromagnet then when the magnetic field collapses because the current stopped then it transmits an electromagnetic wave which can be though of as an incredibly small EMP.

finally while we should promote good spelling and grammar i highly suggest you do it in a better way, just telling someone they are bad at grammar solves nothing but shamming the person. instead describe the proper usage of punctuation and vocabulary and above all else be a good example of proper spelling.

Use dc, and the damage will depend on the strength of the device getting broken
