Creating a Burglar Alarm
Yes, there are a lot of burglar alarms out there, and some are really cheap. But why purchase one when you can make your own? With a few simple tools and materials, having your own security system will be easy.
Learning how to make a burglar alarm, as you will see, is not that hard. To get started you should have 4 pieces of wire, a kite string about three and a half feet long, scissors, a 1.5 volt battery, a wooden clothes pin (the spring type), electrical tape, a 1.5-volt mini-buzzer, a piece of plywood (4’ by 12’ at least), and some glue.
After preparing the materials, you are now ready to learn how to make a burglar alarm. Start by removing a battery wire from the buzzer, and set them both on the plywood. The next step is to use the electrical tape to make sure that the battery stays in place on the wood. Put the buzzer on the opposite end of where you put the battery.
The most crucial part in learning how to make a burglar alarm is creating the switch. This is not the same as the buzzer; this is the device that will trigger off the alarm, and is thus the most vital component of the system. Properly made, it will sound at the appropriate trigger. Begin by enveloping the clothes pin with the wires (be sure to remove the insulators from the wires first, or buy one at a store).
If you want to know how to make a burglar alarm that works, you need to make sure that the wires come into contact with each other when the pin closes down. When that part is set, take one of the wire ends and attach it to the wires on the battery. The other wire should be linked with the buzzer. The other wire should be connected to the buzzer from the taped battery.
To determine if the burglar alarm works, close the clothes pin. Properly done, it should emit a sound. Glue the pin to the wood when you are satisfied with the results. The last step in learning how to make a burglar alarm is by linking the kite string to the plywood. Place it by the door or window, and watch it go off.
That is basically all there is in learning how to make a burglar alarm. Although simple, the principles are sound, and it can be used when you want to construct more complex devices.
