The stun gun (Taser) by Joshua Duryea & Brian Furey what’s it for • a non-lethal way for police officers to subdue criminals • self protection pluses • no long term effects • less risky hiding the taser • camara • cell phone • umbrellas • flashlights hows it work • dumps electrical energy into the victim • momentary paralysis • muscle spasms • PAIN shocking • high volts • low amps • “doesn’t kill” • 20,000-150,000 volts electrodes • electrodes are attached to wires • electrodes are also attached to barbs negatives • one shot • reload • new gas tank the gas tank • the gas tank is what sends the electrodes towards the victim • 15-20 feet • pulling the trigger breaks open the gas chamber building pressure on the electrodes launching them out charge? • the stun gun usually takes a 9 volt battery • this powers the circuit and has many transformers transformers • boost the voltage • lower the amps • oscillator creates a pulse or pattern current / capacitor • the electric current charges the capacitor • the capacitor delivers the charge to the electrodes • the electrodes deliver the shock 2 electrodes • most stun guns have two pairs of electrodes • outer “charge electrodes” • inner “test electrodes” outer pair • Current can’t travel between the outer pair unless something comes between them inner pair • if the charge cant go between the outer pair it goes to the inner pair • the inner pair is close enough that it can produce a crackling noise and spark • the inner pair is used more as a warning The camera Taser QuickTime™ and a Motion JPEG OpenDML decompressor are needed to see this picture. Don’t try this at home QuickTime™ and a Motion JPEG OpenDML decompressor are needed to see this picture. THE END
