Everyone wants to protect their own property, but modern alarms cost decent money, but you can make an alarm from improvised materials literally for a penny. All tools can be found in each apartment.
Watch the video and try to make an alarm yourself do it yourself
We will need:
- medium sized syringe;
- stationery buttons;
- scissors;
- battery or battery;
- Super glue;
- firecracker;
- electronic match;
- ball from the bearing;
We take a medium-sized syringe, disassemble it by simply removing the valve.
At the syringe we cut off the nose, we will no longer need it.
Using push pins at the base of the syringe we make holes opposite each other.
Next, take the battery or battery and glue it to the syringe.
Then we take a syringe, we throw a ball from a bearing there.
We take the clerical button, wind the wire on it and insert the button into one of the holes made earlier.
Next, we take any electronic device that will notify that an intruder has entered our territory. It can be a light bulb, which in case of danger we will blink or a serena with lighting effects, we will use an electronic match.
We attach a firecracker to the electronic match and we wind one end of the electronic match to the second paper clip and insert it into the second hole made.
It is very important that when the syringe is tilted, the ball does not roll out of it, but only touches both parts of the push pins.
All our alarm systems are ready, all you need to install it and connect the remaining wires.
It will act as follows, if we touch our structure, the ball will roll down and close the wires, the match will light up and the firecracker will explode.
The design can be attached to the door, bike and even on car.
