DIY Taser for $5 (not OU but still cool)

[Poit]

Multiple reasons.. I want to experiment with it... try and get it to power a fluorescent light.. maybe link it with Laser Sabres Joul ringer?

And obviously as a weapon... a taser...

Apart from its current state, not sure which direction to go in really.. hence why I am asking for suggestions

good video
heat issues when used for lighting up fl lamps  or joule ringer ......   but might work
with charging caps in primaries to produce resonance which is short duration only
thanks

Does anyone have any suggestions for increasing the power? From what I gather its a simply step up transformer... would increasing the size of the cap on it increase the overall output power?

maybe linking 5 together in series?

any ideas would be appreciated

My good friend Wilby says... Yes, increase the size of the cap to increase output. Be careful not to exceed safe ranges, cap discharges can be lethal. To light a fluoro, remove the cap.

Surely there would be a limit to the output power.. i mean, say I exchanged the cap for a 1F cap... wouldnt it taper off at some point, i mean, wouldn't it not get another more voltage through past a certain capacitance due to the limitation of the circuitry?

Power (Watts) is not voltage, voltage is not energy (Joules). With a bigger cap, you can put more of the _energy_ that is originally in the battery, into the capacitor. If the capacitor isn't leaky it will eventually charge up to the maximum voltage that the oscillator puts out, if the battery lasts long enough.
OK... so now you have all the energy that was in the battery, now in the cap. When you discharge the cap, it can all be released very quickly, much more quickly than the battery could do even by a direct short circuit. Since power is energy/time, you can see that you can attain very high _power_ if the time of the discharge of the energy is very short.
1 Watt = 1 Joule / second.
10 Watts = 1 Joule / 0.1 second.
100 Watts = 1 Joule / 0.01 second.
And so on.
