Taser (stun Gun) From a Battery Charger Adapter V2.0

You should have these tools to make this project. Some of them are unnecessary, but helps you to make it better, and more stable.

• Duct tape
• Hot glue gun
• Wire cutter / Scissors
• Wire Stripper

Of course, you can solder the parts into a circuit board, but in my case, if I solder everything into a board, it would't fit into the box. So I can recommend soldering only if you are pretty sure it will fit into your box.

You will need the following things. Some of these stuffs should be at your home already.

I searched for the main parts on radioshack.com, and I found these prices.

• 5-12V Adapter (phone charger, battery chargers and so on, but keep in mind: more volt, bigger shock) ----5$

• DC Motor (can be found in RC cars, electric toothbrushes...) ---- 5$

• 6.8 ohm Resistor (to prevent the motor from burning down) (You can use other resistors close to this ohm, I used this one, cause I don't have any other small resistor at home. I tried some other, bigger resistors (around 200-500 ohm, but with these ones, the taser didn't work properly.) If you have a 9V dc motor (which is 5$), you don't need the resistor

• Switch (push button, slide switch)

• Copper wires (any kind)

So as a summary, you can make this taser for 10 bucks.
But I'm sure, that you have a motor and/or an adapter laying around somewhere in your house.

Maybe you are wondering, why do we need the motor. Unfortunatelly, I don't know how to integrate a relay into this circuit yet. If you try it out without the motor, you will notice that the sparks are generating after you disconnect the battery. Thats why it shocks once, and then nothing, until you push the swich on and off again. But with the motor, it is like you are swiching on and off rapidly.

This part is the tricky part. The soul of this project.

Adapters always have a circuit board in secondary side of the transformer. It is usually connected with wires into the adapter, so you just have to cut the wires on both side of the circuit board, and connect the wires from the transformer into your circuit. (Next part)

In other cases, when the transformer connected to the circuit with soldering, like in this picture, you have to melt out the transformer from the board, and solder wires to the transformer.

You should leave the electrodes on the adapter, cause these were made from well conductive, hard material, so it won't break, or bend if you are pushing it into something or someone.

As you can see in this picture, this is a pretty easy connection (yes, I made it with Paint :D ).

You have to flip the transformator. The output (was 5-12V) will be the input side, and the input (which was plugged into the wall socket), will be the output (electrodes).

Fortunatelly, I found an old bike light, what used to works with big batteries, so I thought I'll have plenty of space... It barely fit into the housing.

You can fix everything in position with some (many) duct tape.

Pay attention for the motor! DC motors can burn down, if something prevent the rotation. When duct taping things, be sure to leave enough space for the motor.

That's it!

When you push the swich, you should hear the motor spinning. It means that your stuff is working. You can test it with any metal object (nails, scissors), wires, or your finger if you dare to touch it :D
You should see some little sparks as both ends almost touching the metal.
At this point, you earned a handshake. Congratulation! You built your first taser. :)

If you have any question, please leave a comment down below, and I'm gonna help you as soon as possible.

Stay tuned for upgrades, and other instructables.

Have a nice day :)
