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 :)

Would seem an Odd topic ?
 
?
 
What will these be used for ..........[More power?]
 
 
Thx

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

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.

It would make a great HV flyswatter!

You could even use that tennis-racket like thing from the first picture.....

Thanks TK,
Never really thought about it like that.. I think I have some 5.5Volt 1F caps in my box of components, might give that a whirl... ill post a video if i get around to doing it

Poit

(P.S, Since the batteries are 1.5 volt x 2 (i.e 3 volts total), by putting a 5.5 volt cap, that means the cap would never exceed 3volt yea? or does the circuit up the voltage to the cap?)

Hmm.

https://en.wikipedia.org/wiki/Flyswatter#Electric_flyswatter

It looks to me like there are a couple of designs in use. I can't tell which one you've got from the video.

There is one that is just an oscillator charging a final capacitor through a single diode. This one will charge the capacitor to near the full output voltage of the oscillator/transformer which, as you measured, is several kilovolts total (but it looks like the cap is on one winding of the transformer so it won't get that high in total). The other one uses a 3 or 4 or even 5 stage Cockcroft Walton voltage multiplier on the output for even more voltage. The final capacitor in the device, either circuit, must be able to take this full voltage, or at least the voltage of one stage of the CW multiplier. The ones I see are using 630 volt poly film caps.

Can you tell which circuit you've got?

You can get a quite powerful stun gun from new frog for 16 dollars, a real one. How much is the fly zapper ? Edit: My bad I see $5 dollars for the zapper and a fun project, can't lose there well done.

There are many different ones, I know the 928 model works because I've been hit with one.  ;) And have no desire for a repeat event. Here is a tip, never volunteer to be the shock victim. No fun in it at all. The capacitor boogie is not a fun dance.  :)

One feature I like about the 928 model is the HV conductors wrap around the end so if the attacker grabs for it to try to get behind the points the external side conductors get them. hehehehee

928 model
http://www.newfrog.com/p/928-self-defense-high-voltage-electric-shock-highlight-flashlight-stun-gun-26732.html

Variety of units.
http://www.newfrog.com/catalogsearch/result/stun-gun.html?cat=

Very powerful 1.5 inch sparks and quite rapid and very loud.

You could increase the power per pulse on your zapper, but that would lower the frequency of the discharges because the peak power to the cap would be the same about. To keep a person under control the repetition would need to be fairly rapid.

Cheers
