How to Make a Bomb Detonator Chapter 5 (Educational Purposes!!)

From Chapter 4

5.0 Relays as Switch

What are the advantages of using relays over transistors?  Well the following are the advantages of using relays: –

a) relays can switch AC and DC while transistors can only switch on DC current

b) relays can switch on high voltages but transistors can’t

c) relays are a better choice for switching large currents (>5A)

d) relays can switch many contacts at once

The disadvantages of relays are as follows:-

a) relays are bulkier than transistors for switching small currents

b) relays can’t switch rapidly except for reed relays while transistors can switch many times per second

c) relays use more power due to the current flowing through its coil

d) relays require more current than many ICs can provide and hence a low power transistor may be needed to switch the current for the relay’s coil

Let’s just put aside whatever I just said and bear in mind that in next chapter, I will combine both relay and transistor together.  I would like you to just compare the following relay circuit with that of the transistor’s circuit in Chapter 4.  It looks rather similar.  The red and white cables are used to power up or activate the relay (the white cable I am refering to is the white that is on the left not the one on the right side of the relay).

The relay has 5 legs as shown here: –

Here is a close up view of the 9V battery: –

The following photo shows that on the left side, the circuit is open.  If I were to close this circuit i.e. to clip the crocodile clip to the cable, the relay would be activated.

Let’s watch a video on how the relay can be used as a switch: –

4.0 Transistors

The first transistor was invented sometime during the beginning of the 20th Century and through the enhancement of technology, transistors are used today as an amplifier and also as a high speed switch.

You should be aware that since it is used as a high-speed switch, it can be adopted to switch on your bomb detonator.  By adopting the transistor, we do not need to personally cause an ignition event to detonate a bomb.

Before proceeding further, it would be useful to know that transistors when used as an electrical switch, only low voltages should be used e.g. 1A or less.  Also transistors cannot be used as switches for Alternating Current (AC) or high voltages.  Where AC or high voltages are used, the relay (next Chapter) would be a better option but fortunately in this bomb detonator project you are undertaking, we would only be dealing with DC i.e. battery generated electricity.

For the next hands-on task, this is what I want you to do.  Go get any electrical junk you have lying around your house that you will not be using anymore.  It can be a broken computer, laptop, DVD player, radio, etc.  Search for a transistor which has three legs.

After obtaining the transistor, here is what I would like you to do.  Look at the photo below.  Let’s call the light bulb side as the “right side” and the transistor shall be called the “centre” and the 1.5V cell shall be called the “left side”. (Please click on the photo to enlarge it or else you will not see the whole photograph).

The above is similar to Chapter 3’s Lighting a Light Bulb circuit except that it has an additional transistor.  A close up view of the transistor is as shown below: –

At the battery terminal, the connection is as below where the red cable is the positive terminal while the black one is negative: –

Clip the red crocodile clip to one leg of the transistor as shown in the photos below and make sure that the connection is correct.  You also need to clip the white crocodile clip to the centre of the transistor.

Now you can activate / trigger the light bulb just by connecting the cell which is located on the left side and this is shown in the photograph below: –

Again, I end off this chapter with a video for you to watch how the transistor can act as a switch.

3.0 Lighting a Light Bulb

Some of you will be wondering why I came up with this chapter titled “Lighting a Light Bulb”.  Yes, you probably would be wondering because if you look at any simple torch light, you would know how a light bulb works.  But this topic is important becaust this would be the foundation to how you could create a bomb detonator.  You see, I would like to keep everything as simple as possible and hence I introduced this topic.

The circuit diagram to light a light bulb is as follows: –

The photographs of the above two circuit are as shown below: –

Since we are in the age of Youtube, I would like to show how this circuit works in video format.  Please note that, this video is hosted at and again I thank Datuk Chris Goh for his server.  This video is not hosted by that discourages freedom of speech like bomb making techniques.

Congratulations.  You just took one step into making a Bomb Detonator.  Please do follow the next few chapters in order to be successful in making a Bomb Detonator to kill your enemies in enemy territory.

How to Make a Bomb Detonator Chapter 1 & 2 (Educational Purposes!!)


Firstly, I would like to thank Datuk Chris Goh for making me a contributor in this website i.e. From what I understand, bodoh means stupid in his country. Unfortunately I am not from where Datuk Chris Goh resides and thus I do not speak his language. Initially, Datuk Chris Goh approached me (via email of course) and requested that I write an article on How to Make a Bomb Detonator because he found my videos rather interesting after he stumbled upon some of my videos. I wholeheartedly thank Datuk Chris Goh for giving me this opportunity to write here.

Initially, I was very reluctant to write in this blog because I noticed that there are pornographic videos and images in this blog. I said no but Datuk Chris Goh offered to pay me Euro 1 million and I really thanked him for banking in the 10% as promised with no strings attached. Since the other 90% depends on my writting, I would have to get going.

Educational Purposes!! don’t try this at home

1.0 Introduction

This article is focused on how one could actually make a detonator to detonate bombs. Before starting off, there are three main keywords I would like to elaborate i.e. Ignition, Detonator and Explosives.

1.1 Ignition

Firstly, the term worth noting is Ignition. Ignition basically refers to the event, which would initiate the explosion. Obviously if you build a device with no explosives and ignition took place, nothing would happen. For instance, you built the detonator and beside the detonator is a gasoline container filled with gasoline, which you use as explosives. Assuming the container is full, when the detonator causes an ignition, the next instance would be a big explosion. On the other hand, if the gasoline container is empty, there will be no explosion though the detonator created the ignition event.

1.2 Detonator

The second term I would lie to discuss is Detonator. The definition of a detonator is basically a device, which causes ignition. A very good example is suicide bombers where they themselves are the detonators. But since life is too precious to blow oneself up, terrorists decided to adopt animals as detonators by tying bombs to dogs. Besides using human beings and dogs, of course terrorists in the past used cars and trucks to detonate bombs too. Of course other devices such as a clock, a timer, a cellular phone or even a remote control car can very well serve as a detonator.

1.3 Explosives

The last term I would like to define is Explosives. An explosive can basically be defined as a material that causes explosion. Easily available explosives would be flammables such as gasoline, gunpowder or even dynamites for mining.

In this article, I shall not be focusing on explosives but I shall focus on the ignition and detonator topics.

2.0 Ignition

2.1 Executing Ignition

One could simply cause an ignition event by generating heat. The relationship between V = I × R can be easily viewed if one carry out the following experiment. Note that V is voltage, I is the current and R is the resistance.

If we were to use a 1.5V battery, the steel mesh would take a very long time to cause an ignition event. We need to increase the I (current) in order to cause an ignition event.

Two ways would be to either increase the voltage or reduce the resistance. By reducing the resistance, we would need to change the steel mesh material to say a smaller diameter wire i.e. a very tiny diameter wire. The easier way would be to increase the voltage.

In the following videos, you will see how a 9V battery and transformer would cause an Ignition event to occur. Observe as one of the wire strands from the steel mesh turns red hot!


Video 1: A video showing an ignition event using a 9V battery.

Here are some photographs of how the circuit could be set up.


Video 2: A video showing an ignition event using a Transformer

An understanding on this simple technique to create an ignition event is necessary to create a detonator for bombs. In Video 2, this technique would be practical when a bomb is placed in an enemy’s building where electricity is easily available. In Video 1, since electricity may not be available in enemy territory, the 9V battery was hence adopted.
