Introduction: Shock Machine

Picture of Shock Machine

well, its my first instructable so it may be bad if you put bad critics i wont see them but if there are questions i'll answer.
it's very cheap, like 10 bucks or a shock machine, its very funny to put to max level and see the face of the other guy.
its high voltage but low current (it's like 40 v .5 Amp)

Step 1: Components

Picture of Components

you will need:

2 LEDs
1 Variable resistor 100 K
1 Transformer for 12 V with central derivation
1 switch
1 NPN transistor TIP31C
1 Resistor 560 OHM
1 or 2 battery clip (for 4 AA batteries)
4 AA batteries
2 Copper tubes
a lot of wire
soldering iron

Step 2: The Circuit

Picture of The Circuit

well here its the circuit:

Step 3: Thats It !!!

Picture of Thats It !!!

if you want more power you can put a 9 V battery but you have to put 3 LEDs.
if you take it to school you can win a lot of $$$ money $$$!!!

Estas bien puñetas

I was wondering how bad this hurts on a scale of 1-10? Im trying to make sure it does less than 5 because im doing an experiment, also does it have anything to signal that its on, say a light that lights up? Contact me at

Hello, You did not mention the voltage of the LEDS

harry88 (author)2010-06-24

when i hit the button alls that it does is lights up im not very good at schematics could send me somthinge that could help

harry88 (author)2010-06-15

nothing it charges the transformer and then releases the shock once and then you reset it by turning it off

obeltran (author)2010-03-11

hey man i tried hookin it up just like d electrical diagram but it only shocks u wen u turn on an turn off the power switch wat am i doin wrong

bbto (author)2008-05-26

no tengo camara pero baje esa foto, yo la hice.

richgaona2003 (author)bbto2009-12-02

Can you e-mail a hand sketch of what it should look like or type out the instruction on how to do this. I am totally lost.

el triste13 (author)2009-09-28

i got one i got it at mexico for 200 pesos but i think it was at the centro and i kinda makes you money but eh idk here in new york there rare

mattccc (author)2009-09-20

can i use a tip 3055 transister

fregonaz (author)2009-04-01

hey for the variable resistor do we use all three outputs

tom-mot (author)fregonaz2009-06-09

only the two on the left

How'd you win money?

acaz93 (author)Sergeant Crayon2008-05-26

Tell them that if they can handle up to level 8 they will win the jackpot , if they don't , they'll give you 5 bucks

Sergeant Crayon (author)acaz932008-05-27

Sweet. I want one!

westfw (author)2008-05-26

They used to explain that these sorts of devices were "safe" because of the limited amount of power you could get out of batteries. There have been a lot of advances in battery technology since then (that was "Before Alkalines"), and I wonder if such circuits are still safe? The 0.5A value quote is certainly NOT safe; the generally agreed upon dangerous value for current through the body is about 20mA (0.02A) (of course, that's THROUGH the body, not measured on a meter "direct to ground.")

acaz93 (author)westfw2008-05-27

I personally own one of those , and the MAXIMUM OUTPUT CURRENT IS NOT HALF AMP

acaz93 (author)acaz932008-05-27

is just 8 mA

Xellers (author)acaz932009-02-07

If it were really 0.5 A, you wouldn't be here, trust me. 8 ma is much less, and not deadly but still very dangerous. 5 ma is oficially enough to disrupt your heart. As much as you may be tempted to, do not bring thisinto school. If you don't get expelled (not kidding here), then you will still be very sorry.

acaz93 (author)Xellers2009-02-07

you know with 1/3 death cells he output truncates to 5 mA (open circuit)

Xellers (author)2009-02-07

This is a kit, you just reposted the schematics here, in the future, please only post your original work.

Spedy (author)2008-06-05

Hey, this is cool. Reminds me of the 2n3055 flyback circuit, only less lethal. Good job.

Xellers (author)Spedy2009-02-07

Actually, more lethal.

tapatio (author)2008-08-04

Great project - do you have any good sources for finding the transformer? Also could you post some more pictures that detail the individual steps.

Xellers (author)tapatio2009-02-07

Use the transformer from any wall wart or old electronic device (VCR, tape player).

bbto (author)tapatio2008-09-14

I bought everything at steren, maybe at radioshack, I'm not sure.

theXmaker (author)2008-09-15

do you have to touch the 2 electrodes?

Xellers (author)theXmaker2009-02-07

No, it shocks anything within a ten foot radius. What do you think?

AnarchistAsian (author)2008-09-15

nice, but that's not very high voltage, and not very low amperage... good job though!

TheWelfareWarrior (author)2008-05-26

easy, just put a small chain/very long piece of foil from one hand to the other so you dont even feel any of the energy.

acaz93 (author)2008-05-26

La Compraste en steren ! lol

bbto (author)acaz932008-05-26

de donde eres??

acaz93 (author)bbto2008-05-26

definitivamente no de chiapas ...
