Tasers, stun guns, and brass knuckles are without a doubt some of the most frightening non-lethal weapons out there. In this instructable, I'll be demonstrating how to combine all of these into one terrifying portable weapon!

(DISCLAIMER) Some or all of the items I will be using are illegal in some places. Electricity can be dangerous, and I am not responsible for any harm that may occur to you.

If you want to see me testing my Taser Knuckles against 2 other real stun guns to see which one hurts the most, go ahead and check out my video Taser Knuckles and subscribe to my channel Bolillo Kremer if you want to see more crazy taser projects in the future!

Supplies

It's scary how easy it is to make one of these things!

All you will need is...

1 3.7v Lipo/ Li-ion battery or 1 9v
2 metal probes (I used screws)
Some wood .5 - 1 inch thick wood
1 push button switch
3-6v to 400,000 volt boost converter / high voltage generator

Step 1: Find a Knuckle Design Online

First, you will need to find a nice brass knuckle design that you like online, or you could design your own!

In my video I used a design that I found online and then added on to it to make my knuckle look like a monsters face.

Print this design out (you may have to resize the image) and test to see if it will fit your hand by cutting it out inserting your fingers.

You'll want to have at least 1/4 of an inch of space between the top of your finger and the top of the finger hole (so you don't tase your fingers... I learned the hard way)

Once you're satisfied with the design, trace it onto your wood and cut it out.

Step 2: Electrode Placement

It's important to remember that the electrodes shouldn't be too close together or else you'll burn out the boost converter. Depending on how much resistance is in your circuit and whether you're using a 9v or a 3.7v Li-ion, the distance at which you place the electrodes will vary (more detail on this in my video).

Test how far apart you would like the electrodes by using putty or clips and adjusting the distance between them.

When you find the sweet spot, bring them a little bit closer together because there will be more resistance in your circuit once you attach them to the knuckles. Then mark on your knuckles with a pencil where you would like them to be placed.

Step 3: Drilling Holes and Adding Electrodes

When drilling the holes for the electrodes, start drilling holes diagonally into the top as shown in the picture. The taser will arc where the electrodes are closest together, so be sure you drill the holes correctly.

Drill about half way to the finger holes (if you go all the way through don't worry about it)

Then on the face of the knuckles, drill holes that lead to the holes drilled for the electrodes (as shown in the picture)

After the holes are drilled, pull the wires for the electrodes through the face and out the top.

If you drilled all the way through the finger holes, be sure to fill it with something like hot glue that is not conductive.

Finally, wrap the electrode wires around the two metal probes and insert them with a little bit of hot glue into the top holes (For better results, solder the wire to the metal probes)

Step 4: Finishing

To finish, all you need to do is add a push button switch.

I found that the placement of the button in the picture is ideal because you can easily press it while gripping your knuckles.

To add this, you may need to extend the input wires on the boost converter by soldering more wire onto them.

Once the wires are long enough, solder one end of the button switch to the positive input wire on the boost converter and the other to a wire that will connect to the positive side of the battery.

Once you connect the battery you're done and the fun begins!

Step 5: Pain Testing

In my video, I tested out my own Taser Knuckles against 2 other real stun guns to see which one hurt the most.

I found that getting tased through the clothes hurts a lot more than on bare skin!

This is because through your clothes, it allows the stun gun to continue arcing and you will get a burning sensation rather than just a nasty electrical feeling when it's on your bare skin.

I found that convincing your friends that it will hurt less through their clothes is a fun way to get back at them MAKING FUN OF YOU IN FRONT OF YOUR GIRLFRIEND IN HIGH SCHOOL!! >:(
