Abstract

This dissertation is to apply as many basic electrical and electronically knowledge gained during the 3 years study in the Physics with Electronics course into something practical, with primary intention of being educational. The idea is to set up a simple mechanical and also an electronic siren prototype, which is usually available in an ambulance or a police car. Because of the dangers of using real spark plugs and simulating their processes, the prototype will instead be empowered by a 12 volt lead battery and 12 volt, 45 watt direct current (DC) motor. A long, around 5 feet rod steel is welded to Suppurt the shafts and small bottles which represent pistons movements in a car engine. This DC motor is taken out from a submerge motor casing available in mechanic shops, which means this motor possibly can power up a motor boat. In real life, the movement of the shafts of a car engine powers up the vehicle and its components inside, including the air conditioner, radio and digital clock. But it seldom heard that a siren can be put into a car. So, in this project, it is the intention mainly focused on the ambulance siren, which is only used during emergency. Simple explanations will only be used about the movement of a mechanical, which is the car engine and what is the process of voltage circulating inside the electronic siren circuit, without involving complicated calculations.
