How To Make An Emp Without A Camera

Download Article

A favorite device for science fiction and action movie writers is the EMP generator. An EMP (or electromagnetic pulse) has the power to knock out all electronic devices within its range. Be careful because this could exist dangerous. Supervise your kids if they want to try their hands at this.

1

Understand the EMP. You are not going to exist able to create the blazon of EMP you saw in the Matrix or Ocean'southward xi. This type of Electromagnetic Pulse Generator works best for small electronics.
2
Gather your supplies. For this EMP yous are going to take the circuit board and capacitor out of a dispensable camera. Other supplies you'll need are a:
- Soldering iron
- Enamel coated wire
- On/off switch
- Scotch tape
- Apartment head screwdriver
- Pliers
- Core wire
- Wire strippers
- Sandpaper
- A round object near two inches in diameter.^[ane]

Practise safety. You are dealing with high voltage equipment and could get shocked. When removing the capacitor in particular, be cautious. It'south likewise recommended to use a multimeter to approximate the voltage and a battery holder.^[2]
- A multimeter is a tool that measures the electrical voltage of a excursion. You don't need one, merely it will tell you the voltage of your capacitor.

Obtain a disposable photographic camera. It doesn't take to exist annihilation fancy, just a cheap bespeak and shoot you can choice up at any convenient store. Make sure the film is all used upwards before taking apart the photographic camera.
2

Open the case. Using the flat border of a screwdriver, carefully pry the camera apart. Be careful not to touch the printed excursion lath or any metallic parts within.
3

Skid on a pair of rubber gloves. You'll exist dealing with the potential of getting a painful stupor if you accidentally touch the flash capacitor, which carries about 300 volts.
4

Locate the capacitor. It is normally a black cylindrical particular, with ii leads coming out of the bottom.^[3]
5
Discharge the capacitor. Utilize an instrument with an insulated end to avoid getting shocked. An insulated tool has a prophylactic grip that prevents an electric current from shocking you. Slide your screwdriver'due south tip against one of the sealants by the flash to belch the capacitor. You should hear a quick pop followed by a minor spray of sparks.
- Once the initial spark has sparked, you shouldn't need to redo this. As you remove the board, proceed checking the soldered sealants on the circuit board past the capacitor.
- You practise not need to slide the screwdriver'south tip hard. Don't impairment the rest of the circuit board checking for agile energy.^[4]
6
Remove the board and capacitor. Later advisedly taking apart your dispensable camera, remove the board and capacitor. Mark on the battery holder, which side is positive and negative with a mark. Yous'll be able to tell because in that location should already be a battery in the machine.
- Remove the battery from the device earlier standing.^[five]

Prepare your wire. Locate your wire and cutting it to the desired length. Y'all don't want besides much slack, and so endeavour anywhere from 3 inches to a pes. This wire will connect the switch to the capacitor. Y'all'll as well demand to strip the wire from the safety casing.
2

Solder the wire. Solder the wire to 1 of the two terminals of the capacitor. Apply a quality soldering gun to avoid a messy circuit board. Solder a blob of lead free rosin cadre to the surface. Then rut the wire to the hulk with your soldering gun. It should dry soon to create a firm connection. ^[6]
3

Attach to the switch. Take the wire you just soldered to the capacitor and attach it to the "off" side of the switch. You might need to solder the wire onto the switch, just most switches yous buy take screwable ports for wires.
four
Gear up your coil. Wrap a strip of record effectually your circular object with the adhesive side facing outward until it overlaps. At present take the enamel coated wire and wrap it seven-15 times. Get out some wire out to adhere to the terminals. Don't overlap any of the gyre. Take time and be precise. Make certain the wire is snug and that there aren't whatsoever spatial gaps.
- Coat the finished wiring with tape and then information technology'due south secure.
- Slide the windings off the object.
- Cut the terminals of the coils to the desired length, only make sure you leave yourself enough room to piece of work with.^[vii]
5

Remove the enameled coat. Using sandpaper, file down the tips of the wire to remove the enamel glaze. This will create a stronger bond between the components.
half-dozen
Solder the scroll to the capacitor. Attach a strand of coil to the other terminal of the capacitor. Utilise intendance and don't create a mess.
- Solder onto the opposite side of the switch.
vii

Adhere the roll to the switch. Connect 1 of the leads of the coil to the other "on" terminal of the switch.^[8]
8

Fire when ready. Brand sure your battery for the device is charged and in place. Examination the device on a handheld video game. Newer models might not piece of work. Insert the electronic device into the round coil and flip the switch.

Question

What is the theory behind EMP?

The idea is that any conductor passing current creates a magnetic field around it (yes, fifty-fifty a elementary wire). As well, a magnetic field near a usher induces a current through said conductor. The EMP (ElectroMagnetic Pulse) device creates a strong magnetic field in a coil of some sort so the nearby electronics are induced current from that magnetic field. Since all ICs are basically transistors, and the transistor is switched by current, the ICs affected by the EMP stop working, and bear unexpectedly (like resetting, sending signals when they're not supposed to, etc.). If the EMP is stiff enough, it tin can completely fry them.
Question

At what distance can yous knock out a radio?

You volition not knock out any radio with this. You will be able to generate a low-power pulse and observe it on a measurement device like an oscilloscope but that'due south the most interesting thing you can do. This generator does not come close to a human-produced electrostatic discharge in terms of energy. And all electronic devices are shielded against it.
Question

Tin you make an EMP that but causes things to quit working for a while?

The EMP works by creating a surge in the device. Some devices will decadent/scramble retention by flipping $.25 without dissentious the components, assuasive them to be rewritten to piece of work again. Others will damage components, others will flip bits that are non rewritable and ruin those without mill equipment to rewrite them. There is no 'temporary knockout' EMP, just protected and recoverable devices.
Question

What if I connect a larger-voltage battery?

Yous would charge the capacitor really fast. The capacitor is the limiting factor.
Question

How practice I increase the range of this EMP?

Add capacitors in a parallel.
Question

Volition another type of capacitor, such as the ii Farad Capacitor, work for this?

No. Information technology has to be a flash capacitor. Flash capacitors are designed to dump all power in microseconds. The ii Farad Capacitor is designed as a stabilizer for the amplifier.
Question

Is the wire a magnet wire? And what practise I glaze the wire with?

Information technology is an insulated copper wire (commonly known as magnet wire). Go to an electrical shop for it and inquire for insulated copper wire.
Question

Can I make an EMP on a larger calibration?

Yes. There is a mathematical proportion of turns on the coil to level of EMP. Also, the higher the amperage the better; just make certain y'all don't run besides much current through too small of a gyre. If you lot change one, modify the other.
Question

Can this design be modified to disable noisy and speeding motorcycles on our quiet street?

No. This EMP knocks out electronical devices, only a motorcycle is mostly mechanical.
Question

Can I shield an EMP generating device so that information technology will not affect surrounding devices?

Yes, if you lot put your EMP device in a Faraday cage.

Feeling adventurous? De-solder the trigger transformer and xenon flash tube from the PCB, and store or discard them as you wish. Alternatively isolate the section of PCB with the charger circuit and cut the rest off.
