Introduction: Build a World's Smallest Electronic Shocker!

About: ––––––––––––––––––––––– "Energy cannot be created nor destroyed…

This amazing little shocker is very tiny and can be hidden almost anywhere and give someone a surprise shock! It can operated by almost any 1.5v batteries!

So, on this instructable, I will show you how to make shockers that is smaller than a penny!

However, the biggest disadvantage of this shocker is, it is very hard to build, but it may be easy for experienced soldering iron user (like me) to build the shocker...

Please note that I am only 15 years old and I am not very good at grammar so if you find some parts of the instructable confusing, please let me know and I will try fix it.
And excuse me for some of those blurry and hazy picture. I cannot make them better...


New and improved version!

Build a World's Smallest Electronic Shocker! version 2.5



Disclaimer: This shocker can be dangerous, it gives out 450 shocking volts, so I am NOT responsible if you or anybody are injured or killed by the shocker, the responsibility is yours...

Step 1: Get the Things!!

Hardly anything is needed for this project but the tools...
  • "Boots" or "Polaroid" type disposable flash camera (You can use a Kodak camera, but they are harder to work with).
  • Some wires (I got mine from broken electronic devices).
  • Solder.

And the tools...
  • Soldering iron with a micro-tip.
  • Desolder pump (it makes everything so much easier, but you could probably get away with out one).
  • Flat-head screwdriver.
  • Wire strippers.
  • Wire cutters.
  • Pliers.
  • Tweezers or micro pliers (or your hand, but you are more than likely to get a solder burn).

Also, if you don't know how to solder, read this great instructable!

Step 2: Slaughter the Camera!

Now this is going to be a fairly dangerous part, open up the camera and get the circuit out safely without getting shocked by the capacitor...

First, pry open the camera's case apart with a flat-head screwdriver or just use your hands if you like, but you are more likely to get shocked by the capacitor.
After you taken the camera's case off, discharge the capacitor with a insulated screw driver, and you may get a big loud spark, and after that, the capacitor is discharged... (Use a screwdriver you hate so much, because a fully charged capacitor will leave a scar on the metal part of the screwdriver!)

Also, if you don't want to risk getting a shock from the capacitor, Gjdj3 recommends you to wear gloves, even the thin one will help he said.

Great! You had done the dangerous step on this instructable!

Step 3: Continue Slaughtering the Camera...

Okay, after you had took apart the camera and discharge the capacitor...
Desolder all of the wanted components off the camera's circuit (I desolder all of mine off).

The components we will need from this camera are...
  • Transformer with five pins.
  • 22nF film capacitor.
  • 220 ohm resistor.
  • Transistor.
  • Diode.

The rest of the components, you can keep them or throw them away, but the 80uF capacitor and the xenon tube is worth keeping...

The 80uF capacitor can come in great use if you build a coilgun project shown on this instructable.

And you can do some really interesting light effects with a xenon tube if you read this instructable.

If you fail to get the 220 ohm resistor, you can try buy one from radioshack or other electronic suppliers.
Color code of the 220 ohm resistor is:
Red - Red - Brown

Also, be very careful when desoldering (and soldering) the transistor, they are very heat sensitive, so desolder it quickly otherwise the transistor will burn out without showing any signs of being dead. Using the dead transistor on the shocker will lead you to many problems, some people thinks this instructable is a lie, just because they burnt out the transistor without knowing it...

Tip on soldering:Instead of risking a burnt-out transistor, use a heat sink like an alligator/crocodile clip to keep the transistor cool enough while desoldering and soldering.

Step 4: The Beginning of the Hardest Part Ever...

Okay, here we go, build the shocker, the hardest part ever...

Read step by step through this instructable until you get to the end...

Okay, get all of the wanted components, fire up the soldering iron, turn on your work lamp, get a magnifying glass, and HERE WE GO!!!

Also I made a schematic and a design that should help you how to build a shocker...


Step 0: Start with a five pin transformer.


UPDATE - 9, October, 2008
I have improved the schematics, I hope it is easier for you to read.

Step 5: Hardest Part Ever... Step 1

Solder the transistor's base to the pin 4 of the transformer and solder the transistor's collector to the pin 1 of the transformer.

Again don't forget what I said... (Kind of)
Be very careful when soldering the transistor on the shocker, they are very heat sensitive, so solder it on quickly otherwise the transistor will burn out without showing any signs of being dead. Using the dead transistor on the shocker will lead you to many problems, some people thinks this instructable is a lie, just because they burnt out the transistor without knowing it...

Step 6: Hardest Part Ever... Step 2

Solder one lead of the 220 ohm resistor to the pin 2 of the transformer and solder the resistor's other lead to the pin 3 of the transformer.

Step 7: Hardest Part Ever... Step 3

Solder the cathode lead of the diode to the pin 5 of the transformer.

Step 8: Hardest Part Ever... Step 4

Solder one lead of the film capacitor to the anode of the diode and solder the other lead of the capacitor to the pin 2 of the transformer.

You might need to make one of the capacitor's leads longer with some wire to reach to the pin 2 of the transformer.

Step 9: Hardest Part Ever... Step 5

Okay, you are almost there!

Solder the 0v of the battery wire to the emitter of the transistor, solder the positive voltage of the battery wire to the pin 2 of the transformer, and solder the high voltage output wire to the cathode of the diode and the capacitor.

Step 10: Hardest Part Ever...DONE!!!

DONE!!! You did it! You had completed the 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.

Step 12: More Shockers!

I made a shocker with an AA battery, it is very small - it can be well hidden in my hand.


I also built a shocker into a dark blue battery pack, and it packs a pretty powerful punch. I then gave it to one of my friends for him to use for halloween - but then, I later found out he trashed it for no reason... :-(

I modified a orange flash light with a hidden shocker inside! But it is not very effective...

Step 13: Have Fun Electrocuting People and Don't Get Caught by the Police!

Okay, you had built the World's Smallest Electronic Shocker and now have fun electrocuting people and don't get caught by the police! (That wouldn't be good!)

To use the shocker, the victim must touch the live -450v wire and the +1.5v wire to get a unpleasant shock...

The pain of a 450v shock is the equivalent of getting a really nasty static shock from a car. But the shock from the shocker gives a continuous shock...

Also, if you want the shocker to give more painful shocks to the victim, you just simply increase the input voltage!

So, if you give it:
  • 1.5v input = 450v output.
  • 3v input = 900v output.
  • 4.5v input = 1200v output.
  • 9v input = 2700v output. (OUCH!)

Please note the higher voltage you give to the shocker, the sooner it will burn out. If you give the shocker 9 volts, it WILL not survive longer than a few seconds... It is the best if you feed your shocker only 1.5 volt, it may hurts less, but it won't burn out.

Here one fun thing you can do with the shocker.. And this is Kiteman's idea, so credits to Kiteman. (I also edit it a bit to make it better.)

What you can do is wire up the shocker to a battery with a switch and make the 450v wire and the 1.5v wire long and then box it up in a small plastic case (except the long wires) to prevent shocking your self...

Then put the shocker in your pocket and have the long wires running down your jacket or long sleeve and put a insulator like a bandage on your finger tip to insulate you (so you don't shock your self). Then put the bare ends of the wires on top of the bandage and tape it down.

And now you are for some fun! Go into the crowded school corridor and touch people with your electrified finger tip, you might not want to touch the girls as they have a bad habit of screaming their head off if they get an unexpecting surprise, but go ahead and touch them if you want...
Or maybe go into the dinner queue and shock people as they slap the mashed potato on his/her tray...

And what other funny and fun things you can do with this such a small shocker?
