create a small gun to shock your friends, family, or pit bull. (I highly discourage that last one.) and also, it's my first instructable.


Step 1: get parts

the parts you need are simple:

ac adapter (old toys, electronics, etc.)
battery (9 volt)
wire (doesn't matter what kind, I used telephone wire. but if you want it to hurt more, then you could use a wire with multiple wires in it because it would go across the battery more.)
duct tape
Attaching the battery to a simple oscillator circuit (say, a 555 timer) and you wouldn't need to <em>flick the wire across the battery terminal (that flicking creats a half wave semi-ac current where the coil's magnetic field collapses randomly). </em><br/>
I know that I'm bumping a reaaallly old comment here, but what type of circuit would you suggest? I tried a simple 555 oscillator circuit fed into a transistor's base (which should turn the circuit on and off), but it didn't work (I couldn't shock myself with it.)
You are only getting a low voltage oscillation....that pseudo-AC current needs fed into a flyback or step up transformer, which will raise the voltage and lower the amperage. . .
sorry, I should've clarified. I then fed that into this AC adapter (backwards, as per the instructable), which then didn't shock me.
There must not be much of a step up (it has to be an AC to AC adaptor, or the circuitry will foil you.
ah... thanks, I'll see if I've got one somewhere. it would be nice to have something that can constantly shock (attach it to door handles for good fun).
Um, my last post was ambiguous at best....I meant the one you had must not have had much of a step up. If you can get a 1:100 or better step up (an automobile ignition coil works well). Just be careful....the voltage coming out of those can be very high.
alright... hm, it worked when I just flicked the wire across the terminal. I guess there's some difference when it's just using a 555.
how much voltage are you talking as &quot;input&quot; in the case when &quot;it worlked&quot;?
27 volts. <br><br>also, I think you might want to check my comment; I don't think I ever said &quot;worlked&quot;.
Hmm, I doubt that the 555 would handle that voltage, so I am assuming what comes out of it's oscillations (if you have the circuit set up to oscillate fairly fast) would need quite a boost&nbsp; (step up)&nbsp; :-)<br> <br> Yeah, slip of the PHAT fingers there with wolked ;-)
bleh.... maybe if I used a relay, that would be replicating the physical action that I was doing originally. (it would be overkill, but whatever.) I'd probably have to oscillate it a bit slower too to accommodate for the actual physical action.
Well, in a slower state, you are getting some &quot;voltage&quot; from the collapsing magnetic field of the coil too, I suppose.
So it take it that you are backwardsing a step down transformer with a 9 volt battery? I honestly don't know why someone hasn't thought of this before. <br><br>Me wants to try.
yep. I got the idea from a video that showed the same thing. if you want a constant shock type thing, you can try running one lead to a file and another to an alligator clip, then run the alligator clip down the length of the file (which would produce a lot of sparks and a lot of shocks). <br><br>also, fun thing to do -- there's a little spot behind your anklebone (on the inside of your foot) that, when shocked, makes your toes twitch. try it sometime.
It might be more wise to simply conjure up a sort of prong thing to cover the AC plug. It looks rather tempting to plug it in, as it's the only recognizable thing to most people (unless you know what a transformer is. . . )
Pretty cool. I was expecting another camera tazer, but this shows some creativity. Nice.
Hey, this is a great instructable and is very informative. Just one thing is missing... pictures! It really helps a lot when trying to follow directions so you should consider taking some photographs. Once you do that and leave me a message when you have so that we can publish your work. Thanks! Thanks for the cool instructable and we hope to publish this soon!
