How to Make a Taser Out of a Pen


A taser is a gun that fires projectiles to deliver an electric current strong enough to incapacitate anyone hit by it temporarily. The effect lasts long enough for the user to restrain the target. The taser is said to have been invented by Jack Cover in 1969. He was a NASA researcher who wanted to create a non-lethal weapon for use by police or military personnel, one that would allow them a better chance of subduing an enemy without killing them or putting themselves at undue risk.

The idea did not catch on immediately, but the recent evolution of portable phones equipped with a camera and video capability has led many modern-day law enforcement agencies to adopt tasers as their non-lethal weapon of choice.  In this article, I will discuss how to make a taser out of a pen. So let us get started.

How to Make a Taser Out of a Pen

Detailed Functions of a Taser:

A taser is a type of weapon made to take down people. It was mainly intended for law enforcement officers because it does not kill the victim but rather makes them immobile and easily controlled. However, many places have banned these weapons for fear that it will make people overconfident and use their power to hurt others when their lives aren’t in danger.

The primary function of a Taser is to stun the victim so that they cannot move or react. Each shot lasts up to five seconds, depending on how close they were. Although each shot only contains around 50K volts, this can be increased by each additional shot fired at once. This would mean fewer shots would need to be taken as one could hit multiple targets at once. 

A taser not only stuns the victim but also disables any sharp implements that the person might use to harm you, such as a knife, gun, or even a pen (if you are quick enough). It can also be used on children with no adverse effects. However, if you continue to fire at one target for too long, they will be killed from heart failure. As well as stunning your target, it can temporarily blind them so that they cannot see in front of themselves and therefore are automatically given away.

Step-wise Guide on How to Make a Taser Out of a Pen:


Remove the tip of the pen, and get a wire that has a higher length than the stock wire of the pen.


Bend the end of this wire into two small loops. Make sure the loops are facing in opposite directions – for example, left and right.


The taser design has two electrodes with looped wires. The wires need to be binded to the electrodes in a way that an open circuit is formed when electricity is applied. This will help control the amount of current that gets passed on to the victim, and whether the shock will be continuous or not.


Ensure you use some insulation above these looped wires (to protect them from the effects of an electric current). Use some heat shrinking material, glue, etc., for this purpose. Wiring diagram The wiring diagram below is how the circuit was connected to the controller. I tried to present the wiring in a manner which represents how the actual hardware was laid out on the board.

Use Some Heat Shrinking Material


Connect a 12-volt battery to these looped wires such that it forms a circuit when electricity is applied through it.


Make sure you use copper wire for connecting your taser pen with the battery– make sure you don’t use aluminum wire instead – as this might lead to problems during its operation! Do not ever allow your taser pen to come into contact with any water, as this will almost certainly lead to a reduction in its performance.


Ensure you connect the wire from the battery’s positive terminal to one loop, and another wire connected to a negative battery terminal is attached to the other loop in your circuit. Now, you will attach wires from your power switch. Connect the positive lead from the switch to the battery’s positive terminal. Then connect the negative lead of the switch to one end of the circuit loop attached to the battery’s positive terminal.


Now, you can test the effectiveness of your taser pen by touching its wire loop terminals to any metallic object such as a coin or key (i.e., find out if it delivers shock like it was supposed to).

Test the Effectiveness of Your Taser Pen


Make sure you don’t touch both wires together while doing this testing– keep them apart from each other and ensure that even if you touch one terminal with part of your body, the other terminal is not accidentally touched simultaneously!


If you follow the instructions and everything goes according to plan, then you will have a working taser pen that can give electric shocks. This might come in handy if you need to win an argument in the future.

Precautions While Performing How to Make a taser Out of a Pen:

  • Although a pen is made of plastic, you should make sure that the insulation is not damaged, as this can cause a short circuit.
  • You must be careful while soldering wires to the capacitor. Solder all the wires in place so that they do not come off and touch each other accidentally.
  • The battery chamber should have two insulated terminals, one positive and the other negative; otherwise, an explosion may be caused by a short circuit or fire resulting from shorting of live wire ends inside the taser device.
  • After completing making your taser out of a pen, test it thoroughly before using it to ensure its safety and functionality.
  • Before using the taser, make sure you know how to use it.

Why a Taser Gun is Dangerous

The taser gun was invented as a means to restrain or disable someone without doing any damage. It has changed how police and security officials can subdue suspects, but the device also brings with it certain dangers unique to itself.

Instead of using physical force or weapons that can cause serious injury and trauma, law enforcement agents have a non-lethal method of subduing criminals and others who need to be restrained. However, although tasers are considered safe, injuries do occur occasionally, so you should always exercise caution when using one of these guns.

Tasers may not sound like much on paper – they look just like regular pens – but they pack quite a punch if they strike a person in the chest, back, or neck. Tasers work by sending out an electric charge that disrupts nerve and muscle impulses, resulting in temporary incapacitation of the target.

The taser gun fires two small electrodes attached to wires; when they hit their target, the electrical current passes through that person’s body and interferes with their muscular and nervous systems. This makes it difficult for them to move normally or even stand up for several seconds.

The electrical shock from the taser gun can also cause paralysis and cardiac arrest if fired at certain parts of the body (e.g., face). Injuries can occur if people fall after being struck by a taser and suffer serious burns due to electrical discharge. Although, people have been tasered even when they are standing up and walking around.

The most dangerous places to be shot with a taser gun include the chest, neck, and back due to their proximity to vital organs like the heart and spine. Serious injuries can occur if you fall after being struck by a taser and suffer serious burns due to the electrical discharge (but these burns are usually minor).

If you are hit in an arm or leg, there is also a risk of breaking your bones during impact. Since the voltage from this device is enough to overwhelm muscle function, it makes sense that you should not voluntarily jump into water after getting struck by one.

Frequently Asked Questions:

What Is Taser Made of?

Taser is a brand of an electronic control device used by law enforcement agencies to temporarily incapacitate dangerous subjects. The device uses compressed nitrogen and carbon dioxide gas canisters as propellant gases, which are fired from small metal cylinders called “drive stun cartridges” or “drive stun cartridges containing liquid.”

The Taser’s darts contain a barbed wire-like section that embeds itself in the target. Unfortunately, these barbs also deploy an electric current between two electrodes attached to the dart; this causes muscles in the body to contract involuntarily, leading to temporary loss of muscle control and the inability to resist the electrical charge.

Can You Confuse a Gun for a Taser?

Yes, you can confuse a gun for a taser. A Taser is designed to stun someone with an electric shock, while a gun shoots bullets at high speed and causes harm or death.

Which Is Better Taser or Pepper Spray?

Both Taser and pepper spray are self-defense weapons that can be used to defend yourself against an attacker. They have been proven to be effective in stopping an attacker from attacking you or other people, especially if they’re armed with a weapon.

However, pepper spray is much more portable than Taser, and it doesn’t require any batteries for operation, whereas Taser requires two AA batteries for each unit.

Taser has been around since the 1980s and has helped police officers and citizens alike. On the other hand, Pepper spray was invented in 1974 by Dr. Edward Cursi of California State University at Fresno as a defense mechanism against bears to protect his family from these dangerous animals. It is said that after he released his creation into the market, over 4 million units were sold worldwide in just four years!

What Material Are Tasers Made of?

Tasers are made of metal and have a conductive carbon coating that gives them the ability to electrocute. If you have any more questions, please leave them in the comments below.
