Electric Shock Weapon 
An electroshock weapon is an incapacitant weapon used for subduing a person by administering electric shock aimed at disrupting superficial muscle functions. One type is a conductive energy device (CED), an electroshock gun popularly known by the brand name "Taser", which fires projectiles that administer the shock through a thin, flexible wire. Other electroshock weapons such as stun guns, stun batons, and electroshock belts administer an electric shock by direct contact. A shockround is a piezo-electric tip for a projectile that generates and releases electric charge on impact..continue..

How Stun Gun Works? 
On th­e old "Star Trek" series, Captain Kirk and his crew never left the ship without their trusty phasers. One of the cooles­t things about these weapons was the "stun" setting. Unless things were completely out of control (as they frequently were), the Enterprise crew always stunned their adversaries, rendering them temporarily unconscious, rather than killing them.
We're still a ways off from this futuristic weaponry, but millions of police officers, soldiers and ordinary citizens do carry real-life stun weapons to protect against personal attacks. Like the fictional phasers of "Star Trek," these devices are designed to temporarily incapacitate a person without doing any long-term damage..continue..

Basic Stun Gun Concept 
The main power limitation to these two devices is T1. These are actually minature "Audio Transformers"
connected in reverse to step up the 12 volts to around 400 volts, with no load.These are not ideal parts for this purpose as they don't have the ability to produce the high currents that would result in a more sustained spark on the output.This Medium powered version has a center tapped primary with dual transistors, resulting in a more efficient circuit. For Simplicity and "Off the Shelf", this was the best I could do. If your an adventurist, you could wind a small transformer for any of these units below. This would allow for higher efficiency and more current draw...continue..

Stun Gun Discussion 
This stun gun is powered by a 9V battery. The transformer steps up the voltage to about 1800V (but with very low current). A 555 timer IC is used to generate a high-frequency output. A 1 MEG variable resistor can also be used at the output to drop the voltage, but this is optional. If you build this circuit, be careful, as it outputs a high voltage. Touching the output leads will induce a painful shock...continue..
