Hi, I'm juz found this forum and its GREAT~

ermmm i have a question here abt the stun gun.
i cant seems to find the audio transformer mentioned in Rick Duker's Electronic Dazer (1st link)

is there anything else i can replace it with or any webbies i can find purchase it frm? or mayb, item that might have the part inside it.

Its for my sch project. =)

 

If you're referring to the 200KCT-1KCT, I gave a link to it in my post.

Take that Einstein.

 

ermmm i'm refering to 1200 to 8 ohm audio power transformer.
the 1st link

oh and the link...there was no matches found after the search.

 

Thanks for the kubaton tip, but no one has answered my question yet...

 

The only way this design will stun some one is if you throw it hard enough !
I personally worry about the way this thread is starting to sound - 'GBH' springs to mind, however -

In order to 'stun' you will need to deliver in excess of a hundred joules of energy, an open-circuit voltage high enough to overcome any resistance will be required - maybe a few hundred volts for bare skin, several (ten?) thousand volts to penetrate clothing (or fleece/fur!).
I know that ten joules and 10,000v (a typical small farm electric fence energiser) is painful but safe (except for extreme cases).

The Nazis did some excellent (though morally outrageous) research during the Second World War into current flow in human bodies and its effect - they produced the data still used today specifying the minimum current that can be felt etc. Thanks (in part) to PoW suffering we now have legislation under whch you could be prosecuted if your stun gun is not 'safe'.

sorry wrong forum i think :lol:

 

I built a stungun once, and used it on a big guy who was about to rough me up some. He was still out when the ambulance came. I thought I'd killed him. Afterwards he couldnt remember a thing about it.
I'll wait a couple of weeks to allow the moderators to advise me not to send the circuit.

 

would anyone be able to post a pic of the dazer stun gun after its been put together?

 

Hi guys.
I'm planning to experiment with a stun-gun project.
I think this design it's quite simple, but it doesn't provide enough power to achieve effective stun.
http://<a href="http://www.rlocman.c...a06002.htm</a>
May I use 2 transformes directly hooked primary-secondary-primary to increase voltage?
By example can i use 2 easy to find 20/1 transformers to obtain 400/1 ratio?
I think it's a quite simple solution but i have never seen in any schematic so i thought that it would not work.
Do i need an intermediate circuit
between transformer?

Bye

 

If you just want to play with high voltage check this link out. I built it for an ignition system for my home built turbine so I know it works. This thing will nock you on your butt! :twisted:

Hi,
I live in Australia and we have hardly any electronic parts here, and so i cant find the pieces i need...

i am trying to build THIS but i dont have the D2(1n4005) which is 600v but we've only got the 1n4004 which is 400v...would that really matter?..and i cant find a 200k to 1k C.T audio transformer, i would order it international but, it;s just a transformer, so that'd be a waste of money, because of all the shipping fees....

SO i thought i could use a 1200ohm to 8ohm transformer, but i'd need a voltage multiplyer right? SO instead of using the Voltage Muliplier in THIS, I want to use a better one, that produces a better shock, what type of DIODE and CAPACITOR should i use? Because freeze said he didnt get any good sparks..?

Thanks...

 

hi Azn Chum,

And i thought i was the only azn aussie on the forums !!!-There is a place called Jaycar in Australia. What state do you live in ?? They don't sell those 1k/200k transformers however but they do have a 8/1k transformer. This means a 1:125 ratio, not a 1:200 ratio.

That means that you will get 37.5 % less voltage. Which equates to:

9v x 125=1125 volts with the 1:125 transformer, and
9v x 200=1800 volts with the 1:200 transformer.

Thats a voltage difference of about 675 volts. this doesn't matter as 1000 volts is enough to hurt!

however to compensate for the massive loss of primary windings (there is 125 times less primary windings) we should step up the frequency by 125 times.

Time constant equals: RC

1000 ohm x 0.000,000,01 = 100 micro secs/125 = 800 nano secs

so changing c1 to a value 125 times smaller would compensate for the less windings in this case:

0.1 uf/125 = 800 pf. 820 pf would be fine but i would suggest a 680 or lower to avoid the voltage drop under load (when shockin' someone)

NOTE: I would also recommend sharp contact terminals to pierce the offenders cloths so you can shock them properly with the slightly lower voltage!!!

have fun :twisted:

hi pike and anzchum
im yet another aussie trying to pain some cows.

i am making a cattle prodder from the exact design you are anzchum. thanks to pikes expertise i am going to try that capacitor thing. i am using a 1k-8ohm transformer and i added an extra multiplier stage but i only seem to get out 100v by testing it on a multiplier stage. i am doing a school project in port macquarie year 12. so thanks heaps i will try that capacitor and get back too you both.

 

I want to know about your home built turbine!?

 

im on the finishing touches of a tazer right now its about 5 kv it will go through 5 m ohm resistancs and still arc half a centimeter how can i see how effcitive it is, how do i measure the current flow? without burnining out my 600$ multimeter :?:
