Portable batteries and electric shock gun
Could a 10000mA portable battery be modified into a electric shock gun? -- @~@ Remain silent. Nothing from soldiers and magicians is real! / v \ Simplicity is Beauty!

You can get a hint of the operating principle here. http://electronics.howstuffworks.com.../stun-gun3.htm That should tell you, the circuit doesn't have to be physically big, to be effective. The trick, is not to kill someone with your experiments. A study in human physiology should be your first step (lethal voltages and frequencies), rather than running off looking for a schematic. The reason that's important, is you could build a Tesla coil by accident, produce high frequency high voltage AC, and get no appreciable shock effect from it. At high enough power levels, a thing like this can burn stuff. But you won't be shocked by it. The high frequency "skin effect" is what prevents most of the shock effect. If the voltages involved here were low frequency, like DC, that would be much more dangerous. http://en.wikipedia.org/wiki/Tesla_coil I built one of those Tesla coils, but my glass-form coil was only one foot long :-) The sparks were pitiful. ******* Voltage doubler or tripler modules, can perform the conversion from AC to DC. Now your circuit is a lot more dangerous. TV (CRT) repairmen can probably relate a few stories. http://en.wikipedia.org/wiki/Voltage_multiplier Paul |

Could a 10000mA portable battery be modified into a electric shock gun? So just how are you going to up the voltage of that 3V battery (or whatever is the low voltage)? By the way, what you ask for (provided once the voltage is sufficient to overcome body resistance) is for an electric fry or kill gun. It only takes 10 mA @ 110 VAC or about 1 W/sec for half a second through the heart to halt it hence why GFI breakers are set to trip at 5 mA in 0.033 seconds. You don't mention the conduction path. If it's across a couple of contacts a few inches apart then 10 A at sufficient voltage is going to burn flesh. Voltage doesn't kill (e.g., a Tesla coil makes your hair stand on end but doesn't kill you). Amperage kills and the level you mention won't just stun but fry and kill. But then 10 A really doesn't say anything about the current the battery can supply over time or the capacity of the battery to sustain a current load at what resistance or for what voltage. You want changing (pulsed) high voltage to force synaptic action in the nervous system, not high amperage. A stun gun may operate at [hundreds of] thousands of volts but only supplies around a 3 mA load. http://electronics.howstuffworks.com...s/stun-gun.htm A CR-123 3 volt that can deliver 1400 maH (notice the inclusion of time, not just load) is used in stun guns. I've seen stun guns that advertise using a one two 9V batteries, like the Energizer 6LR61. You never mentioned what battery you're thinking of using that is obviously larger than needed to stun only. |

TV (CRT) repairmen can probably relate a few stories. http://en.wikipedia.org/wiki/Voltage_multiplier Paul I also experimented with a large Tesla coil, secondary coil was three and one half feet tall on a four inch fiber form. The primary gap was fed by a 15,000 volt neon sign transformer and was tuned with 2 foot square sheets of glass and aluminum foil capacitors. The output corona sparks were about 2 feet log and when it was on all the fluorescent lights in my basement would light up. I would turn it on by plugging it in on a 20 foot extension cord, It was great for killing TV reception for 2 or three houses in each direction until the DOT (FCC) snooper van started combing the neighborhood Then I stopped playing with it and hid it in the attic, Boy, Those were the good old days.

I was merely checking the possibility. No plan to really make one, as doing it will make me a criminal in Hong Kong!

Actually, I saw an item on Fox news this morning regarding "attack shoes" being sold in Thailand(?). It's for use by women & has a battery with a push-button by the heels; the use is defensive against rapers & other attackers. The concept is to always have a shock/taser available. Your idea isn't too far fetched! |
