Chapter 8 Remote Bomb Detonator

Note: This chapter is VERY similar to Chapter 7.  However a diode was adopted

In the previous chapter, I asked you to look first at Chapter 6’s last photo. Please do that again. Here is the URL for that photo ( ). Now also, look at the previous chapter’s first photo ( ). You will notice that both are almost the same except one is using a battery cell (for a messy blow job) and the other is using an alarm clock.

Now, I would just remove the alarm clock and replace the alarm clock as shown in the photograph below: –

Hey, I bought a new remote toy car with part of Datuk Chris Goh’s 10% payment. The box is still intact as shown in the photo. Obviously you cannot clip the crocodile clips to the box and expect it to become a remote bomb detonator. Well, take the toy car out from the box.  Test out the toy and make sure the wheels are spinning: –

On inspection, I am lucky to discover that this Made in China product has the two cable exposed at the rear wheel end.

Obviously those are the cables to the motor and I don’t need to dismantle the whole car. I just need to make some minor incisions to the cable to expose the metallic part like this.

Clip the exposed cable.

However, as mentioned in the beginning of this chapter, a diode was adopted. Clip the diode as shown below: –

The reason for a diode is very simple. Motors are sometimes not very stable. It sends out tiny electricity signals. If you adopt a diode, that would take care of this signals. Even with the alarm clock project, some alarm clocks may or may not need a diode.

Now set up the whole circuit as shown like this

For the movie, you can view it here:-

7.0 Alarm Clock Detonator

Firstly, let’s take a look at Chapter 6’s last photo ( ). It depicts a battery and two crocodile clips. If you are a suicide bomber willing to sacrifice your life by blowing yourself into pieces in enemy territory, just run to the enemy and close the circuit of the battery.

However, I did mention that life is too precious to perform this sort of messy blow jobs (pun intended).

Now, if we were to replace the battery cell with this (alarm clock): –

(click on the photo to enlarge it)

Then, the explosion time can be set. You basically need an alarm clock which has a motor. The motor sends approximately 1.5V of current which is adequate to trigger the transistor. Remember the last photo of Chapter 6? It’s a cell with 1.5V.  So the alarm clock’s motor is a good replacement. Let’s have a look at the motor: –

If you paid attention to my class from Chapter 1 to 6, you should have no problems here.  Hence the very short write up in this chapter.

Let’s watch a video of how this works: –

In this video, I started off by clipping the green crocodile clip to the 9V cell. This 9V cell is essential to cause the short circuit and consequently resulting in the Ignition Event. But of course you already know that this would not be powered up if there is no signal sent to the transistor. Then I move on to the alarm clock and pointed the alarm clock button and the match stick. I then pressed the alarm clock button and the match was ignited. Of course I could have waited like half an hour or so and make it work like a real alarm clock bomb detonator but I am sure you wouldn’t want to watch a movie where nothing happens only after half an hour. So, I “fast-forwarded” the process by pressing the alarm clock button and the bell rang immediately. When the bell rang, electrical signal was sent to the transistor and this sent another signal to the relay. Since the relay is triggered, the 9V battery’s circuit began to lit up the match.  Hence the Ignition Event

6.0 Combining Transistor and Relay

All the photos and videos you viewed previously may seem hopelessly useless to you but trust me if you are able to recreate the same circuits that I demonstrated from Chapter 1 to Chapter 5 and if you continue with Chapter 6, you should be able to create your own detonator successfully.

In this chapter, I shall combine a transistor and a relay.  Besides that, there is no more light bulb.  Remember in Chapter 3 I demonstrated how to light a light bulb? Well, now the light bulb’s location (i.e. on the right side) has been replaced with a matchstick.  Of course you could combine the matchstick with something more powerful to kill your enemy.  For instance, you could always combine the matchstick with dynamite.  However, as mentioned earlier, I shall not be discussing on explosives because this article is solely on detonators.

Previously, the centre portion had either been a transistor (Chapter 4) or a relay (Chapter 5).  Now, I changed the centre portion to have both the transistor and a relay.  The left side still maintains as a battery cell.

Anyway, the descriptio of what I said above is depicted here: –

As usual, the matchstick is ignited via the action of short circuiting (see Chapter 1 & 2) which creates the Ignition Even: –

Some close up views are as shown below: –

The relay’s connections remain the same as the previous chapter ans is as shown below: –

Here is a close up view of the cells used to trigger the relay.  don’t be worried as to why there’s one small cell above.  You see, I need about 4V to trigger the relay and so I had 3 times 1.5V cells which is equal to 4.5V.  There are many types of relays.  If your relay is a 9V relay, then you need a 9V power to trigger the relay.

Here are some close up views of the transistor.

The final photo below is the trigger which will trigger the whole circuit.  In other words, when you connect the crocodile clips to the appropriate terminals, the matchstick would light up!  Unfortunately I didn’t manage to make a video of that.  Well you just have to imagine that the matchstick would light up.

Now just use your wild imagination!  If a 1.5 V battery can trigger the above circuit, what would you use in place of this 1.5 V battery?  Almost anything!!!

To do a booby trap, perhaps you could have two metal plates, parallel i.e. one on top of the other.  When your enemy steps on the top plate, it touches the bottom plate and this would trigger a bomb detonation.

Besides that, if your enemy is entering a building through a door, you could similarly thing of a trigger mechanism to close the circuit and blast your enemy to pieces using this detonator and powerful exposives.

Yes, you can let your imagination run wild and think of many other methods to blast and cause your enemy to die.  Hey, that’s what soldiers do to defend their country right?  Anyway, what else can you think of as a detonator?  Well, obviously you could use a cellular phone.  After reading Malaysia’s news where the Malaysian Airlines System or MAS allows passengers to use handheld devices on board of the plane, I feel that it is a bad move because do note that cellular phones can act as a detonator too!  Just imagine replacing that last photo’s 1.5 V cell with a cellular phone!

Anyway, to continue with the next chapter, I would introduce something easily available i.e. an alarm clock and a remote control car.  So, you will then know how to create an Alarm Clock Bomb Detonator and also a Remote Control Car Detonator.

Due to time constraints, I am not able to discuss on Cellular Phone Bomb Detonators but the principles are the same as the Remote Control Car Detonator.  You just need to get the two “trigger cables” to the motor of the Cellular Phone like how you get the two “trigger cables” to your Remote Control Car (in Chapter 8).

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.
