Introduction: Handheld EMP Device
EMPs (Electromagnetic pulse) are quite popular in the world of science fiction. Wouldn't it be cool to have one of your own? That's what I thought when I started building it.
I wanted to make an EMP which will be portable and which can be hidden under full sleeves( That's naughty!). If you have the right parts, you can build it in no time. If you don't, you're in trouble.
WARNING: Not for children under 15 yrs of age :D
Well seriously, If you get a shock it'll shake your spine. These capacitors are really powerful. So please be cautious while handling the circuit.
I SHOULD NOT BE HELD RESPONSIBLE FOR WHATEVER THINGS YOU DESTROY
Step 1: Step 1: the Absolute Necessity
An old camera circuit, doesn't matter whether its disposable or not is absolutely necessary. If you don't have one, its not that tough to make one, but it'll take lots of time. An alternative way is to use the circuit of a zapper or a separately sold camera flash.
I used the circuit of a 15-yr old camera. Just had to take out the circuit out of it. The circuit runs on a 3V battery system.
The reason I used a normal camera circuit in place of disposable ones is that the capacitor in a normal camera is much more powerful than the disposable ones. If you use the circuit of a separate flash, its even much more powerful than the normal cameras.
Please be careful while taking out the circuit. The capacitor might still have stored charges.
Step 2: Step 2: the COIL
I had to make a coil which won't cover much area because I had to fix the coil on the palm of my hand. If the coil is too large I can get a nerve-racking shock just my slight movements of my palm.
So, I took out a coil from an old SMPS circuit. I had extra copper wires. So I used them to make a more powerful coil.
Make sure that the winding of the copper wire is tight. Otherwise it'll be ineffective.
Step 3: Step 3: Getting Started, Making the Skeleton
We have to fix the coil somehow with the palm. Also we have to make sure of proper insulation to avoid getting shocks.
I have used a metal strip and a thick cardboard to provide the insulation. After that I have used a walkie-talkie antenna which I fixed with the palm-part with tape.
The point of fixing the antenna is to allow the palm to move freely. It should be flexible so that you can bend your hand properly.
Step 4: Step 4: Adding the Vital Organs
Now that the skeleton is built, we have to attach the most important part, the camera circuit. Again I have used cardboard to attach the circuit. Also notice that I haven't removed a part of the antenna jacket. This will allow me to rotate my palm about the wrist. I have attached the circuit with this black jacket.
Step 5: Step 5: Some More Bones for the Skeleton
The whole structure should be so built that it stays on your hand. We have attached a metal strip before so that the coil stays on the palm. Now we have to attach another metal strip so that the circuit-part stays fixed on the forearm.
To make this happen, I've used a magnifying glass frame.
Step 6: Step 6: the Source of Energy
Attach a AA battery holder with the circuit. First find out the points in the circuit where the battery leads were connected before with the circuit. Solder the wires properly.
Step 7: Step 7: Attaching the Coil
First connect the wires properly with the coil. You can solder the wires with the coil. One wire is to be attached at the beginning of the coil, the other wire at the end of the coil.
These two wires are to be soldered with the two electrodes of the capacitor in the circuit. Don't forget to attach a switch. Attaching the switch is important.
Step 8: Step 8: Finishing
I have used yellow insulating tape to attach the coil with the palm- part.
The battery holder is attached with the forearm-part with tape.
Its time for destroying something!
