The Super Capacitor Based 30kv Taser Stun Gun Prototype - Fast Rechargeable - 5.3v to 30kv.wmv

I was just messing around this afternoon, and this is what I came up with. Thankfully I didn't need to gather parts and design a FET switching design/Oscillator, as my transformer only requires 5v to operate. The capacitor flash light charger module charges the small capacitor bank to roughly 5.3v. When charged (5 minutes for full charge), you can unplug it, and start arcing using the power button, which applies the charge on the super capacitors to the transformer.
