How To Make a DIY Taser / Stun Gun: A Step-By-Step Guide

How To Make A Homemade Stun Gun

Every pepper needs to have some kind of self-defense weapon lying around to keep unwanted guests out of your home. But if you’re not comfortable using a knife or just want to use something a little more special, you could opt to go for a homemade stun gun.

A stun gun is used to incapacitate a person by shocking them with electricity from proximity, while a Taser is a branded stun gun that can be used further away from your attacker. Where a stung gun can be quite cost-effective, a Taser is a costly product.

Know the difference between a taser and a stun gun. a taser is gun shaped and fires metal prongs that penetrate  the skin while a stun gun uses metal electrodes that shock via direct contact.

These devices are handheld and use a charge to send an electric shock through a victim. These electronic devices are used in a number of situations, including personal safety, law enforcement and military training, crowd control, and animal control. While most stun guns work by using an electric current, some models include a high voltage, low amperage battery system. 

Most professional stun guns work with high voltage capacitors that will hold a charge and wait for it to be released, but most home made stun guns you find on the internet don’t use capacitors. Instead, they use resistors to create a oscillating current.

Sure you can buy one. But it’s more fun to learn how to make a Taser. In this blog post we’ll be going through a couple different ways to learn how to make Tasers.

Here’s the materials you need to make this tutorial:

Step 1: Make a circuit

Using the above circuit, start by solder on a couple of electrical wires onto the positive and negative part of the transformer. These will go to the battery. Temporarily disconnect the connector part of the battery, we’ll be adding it back on a bit later.

Connect the negative battery terminal to the negative transformer terminal and then attach the positive transformer terminal to one end of the switch. Add another wire to that switch and then solder on a button.

Then the wire that goes from the button switch will connect to the positive side of the battery. Now connect the wires, one going from the switch and the other wire going from the negative terminal of the battery. These two will go to our indicator light to tell us whether the Taser is on.

Now since I have a rechargeable battery, I would want to attach on a connector to that battery. So the red wire to the red wire and black wire to the black wire to finish building the circuit. And with that, the circuit is complete.

Step 2: Add the shock point

Since the high volt transformer wires aren’t long enough, we’re gonna add some electrical wires going to the ends that will send a charge through. Now for the ends use some short nails or you can substitute them for screws to get it working. You can leave them apart now as you’ll be moving them into position later.

Step 3: The housing

Use the plastic boxes to create the shells for the stun gun. You’ll be using 2 of them to create a longer stun gun that can house all components. Mark out the places for the led light and the switch and the button and drill them out.

Drill the hole where the screws will sit. The best distance between each tip of the nail should be around five millimeters to get a nice discharge.

Put hot glue in between the two nails making sure that the popsicle stick is not glued. That’s just what’s keeping the two apart. Glue all the components in the circuit into the bottom shell of the Taser.

To prevent any explosions from the nail touching the battery we’re going to glue a piece of cardboard or something similar, this will function as a wall between the two, to ensure that the nail doesn’t directly touch the battery. Use epoxy where needed to separate the components or use some electrical tape where needed.

Step 4: Closing it up

Close the components en use some epoxy to seal the gaps then sand them down so create a smooth housing. once you finish sanding your Taser take pieces of masking tape and cover any of the spots that you don’t want painted. Then spray paint the Taser any color you would like. And there you have it. One Taser.

What You Will Need | How To Make A Homemade Stun Gun | Homesteading Survival Skills
  • High-voltage converter
  • 20 cm PVC pipe
  • Safety switch and a momentary switch (main button)
  • 3 As battery and battery housing
  • PVC coupling and soda bottle cap
  • 2 small brass nails
  • Black matte spray paint
  • Cutter and pliers
  • Glue gun

Step 1. Prepare Materials

preparing materials to be assembled into the housing of the stun gun

As a homesteader who creates, builds, repurposes, and recycles, you may already have the materials lying around to make a homemade stun gun at home or in your tool shed. So you may not needs to spend a lot of time and money gathering all the materials.

For the inverter, a high voltage low amperage one, specifically one which can produce up to 400,000 volts is better to use. Take out the outer layer of the inverter for the circuitry part to fit in. Using a cutter and pliers, carefully peel off the outer layer of the converter. Once the outer layer is gone, the inverter will easily fit in the PVC pipe.

Step 2. Assemble The Circuitry

Assembling a stun gun circuit using electrical components

Prepare 3 triple A batteries and battery housing which will fit in the PVC pipe. The Taser should also have a safety switch with a push button that lights up when pressed so you can easily see if the Taser is on or off. You will also use a small momentary switch as the main button.

Check out this basic circuit diagram or electronic schematic to assemble the basic circuitry.

This elementary electronic schematic shows how you will assemble the circuits to make the Taser work. The battery is connected to the on and off safety switch which is the red LED button. It is then connected to the momentary switch that we press to make the Taser spark. This leads to the high voltage converter connected to the spark gap where the spark zaps through or between the two prongs which lead back to the battery.

Step 3. Prepare Stun Gun Housing

Now we go to our PVC pipe. Spray paint the pipe with a black matte spray paint and leave it to dry. Cut the pipe in two so you can have access to the batteries when replacing them after they’ve run out. Measure 13 cm from one end of the PVC pipe and cut from there so you have another 7 cm PVC pipe. Next, Drill a hole for the main switch some 4 cm from the top of the longer PVC pipe where the momentary switch will be inserted. Use a PVC coupling to join the two separate PVC pipe pieces securely and for replacing the batteries.

Step 4. Assemble Stun Gun

Next step is to assemble the Taser. neatly pack is all in the tube and close it off with the cap.

Step 5. Finished Homemade Stun Gun

Finally, you can test your finished homemade stun gun, be careful of getting shocked! Make sure to take safety precautions and use this weapon for self-defense responsibly. Also, make sure to keep it out of reach of your youngsters.
