How to Make a Bomb Detonator Chapter 7 (Educational Purposes!!)

From Chapter 6

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): –

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
