Build a World's Smallest Electronic Shocker!

Step 11: Testing... Testing...

Okay, now it is time to test the shocker to see id it works...

Yay! Mine works!

If yours does not work, calm down, don't get so angry and blow off your head about hours of work for nothing.
First, check your shocker closely, are there any wires touching each other? If so, move them apart a bit.
If it still does not work, you probably killed the transistor from putting the soldering iron on its leads for to long, replace the transistor and don't keep the soldering iron on its leads for to long again. If it still does not work, build another shocker.

And if it STILL does not work, well I guess you can you can go very angry, and smash up the "I won't work for you!" shocker with a hammer and get over it.

you really gotta see where you wires are, my transistor was getting hot because a tiny piece of wire connectedthe emitter to the base, shorting the circuit.

[ElectricMan1]

What if you put this up to a 12v 10ah battery? It would burn out the transformer woldnt it.

[Kirbsome!]

Not the transformer, but rather the transistor.

[UbuntuNinja]

You mean if I replaced the transistor with a more powerful one i could hook the thing up to a 9V battery and it would not be damaged? If so what transistor would you recommend using?

[joinaqd]

indeed..i burned out one of my transistors cuz i put too much voltage in.

[Kirbsome!]

also, this is scalable, right?

[thesorrow]

plasmana , how about you put a cap in tank circuit so the coils are in reinsonance and they will not heat up.

[thesorrow]

And a stronger transistor like 2 Watt or something

Mine is reading just under 700, is this right?.....also when i touch it to a screwdriver it emits a continous (very) low sparking shock. Is the sparking supposed to be farely big or small? ....i havent touched it yet so once i find a victim i will really test it.

[codex653]

yeah mine does this too. pretty cool huh? i think we can make this even higher voltage by replacing the capacitor with one of a higher voltage and a lower capacitance so it'll charge and discharge faster and create that little taser sound. i'll try experimenting with it later and maybe create an instructable for it if it works???? i've accidentally touched this and it actually really isn't that bad. if you've every touched a fully charged flash cap you know that it hurts like no other, but for700 volts it only feels like 100. i've shocked my self before with one of those sparkers from a lighter...the lighter feels worse than the 700 volts. i've measured the lighter spark before and it came out around 130v.

[Plasmana]

I don't know how you manage to get 700 volts but if it works, that is great! And the sparks are supposed to be small.

Hi plasmana, awesome tutorial. I just wanted to know the working principle, i mean how this works, why we're using all this specific components n all, u know what i mean? I've basics of electronic so don't be afraid to use hi-fi terms. Mail me if the explaination is long which i think so will be. ID: [e-mail]
Thanking you..

[codex653]

he replaced the transistor with a more powerful one i think. i have a power transistor on mine in a heat sink and i can hook up ten AA's to it. one thing i found though was that the circuit has a "peak" out put voltage with a certain input voltage. i guess you could call it the voltage input "sweet spot" of the shocker. mine was around 7.145v and it produced between 755-763v once you got any higher in voltage it dropped and held to around 710-720v i've only tested it so far with with a max of 10.083v but it has held up very very well so far! thanks for the amazing instructable!!

[mayday295]

ya me neither....but i have the perfect contraption for my new "taser". An old electric plane charger, i just put holes on the top for wires, and can hold 4 batteries, also has a button so that it wont waste batteries until button is pressed (and held)....thanks for the great instructable!

[Plasmana]

Your welcome and have fun!

[mayday295]

one more question...since my first rig with 4 batteries didnt seem to work, what could i do differenly to be able to use 4 AA? (i have lots of parts in my garage i can choose from, plus radioshack)

[girrrrrrr2]

darn... that didnt seem to work... i had it hooked up like you showed... and i was recieving less voltage than the battery had... would replacing the part with the 3 prongs work?

[eggman]

the part with three prongs is a transistor, and you probably just have a short somewhere, check everything first

[girrrrrrr2]

ok i will check it... is there any reason that i am getting such a low voltage if i am using a new battery and it had no shorts?

[eggman]

sometimes it just doesnt work. i just made a second one exactly like my first one. the exact same thing ad im getting 4.5 volts out with 3v in. makes no sense

[zim0909]

What kind of amperage do you get on that thing? I'm very curious because this looks very evil hehehe.

[Plasmana]

It has an average output current of 10mA (short current output is 18mA) with 1.5v input.

[zim0909]

Nice

[DanCat]

What kind of battery is that? AA 1.5V ?

[Plasmana]

No, it is an 123 AAD battery. LOL! J.K! It is really an ordinary AA battery!
