ABSTRACT An audio AMP is basically a system which is used as a means of increasing the level of sound or audio signals for maximum use. A public address system consists basically of  microphone, Amplifier and speaker(s) to facilitate the communication to intelligible speech to groups of people or an audience. The main purpose of providing sound reinforcement indoors with sufficient high – fidelity being the coverage of large groups ...

ASTRACT This project is titled the design and construction of a DC to AC inverter system. It is designed to meet up with the power demand in the offices and in homes in the absence of power supply from the national supply authority, NEPA. In order words the device / item serves as a substitute for NEPA which almost monopolises the power supply to people. It is designed in such ...

ABSTRACT The very fundamental reasons behind this project assignment is to expose student to the very important aspect of private and independent research work not only theories but also subsequent translation of the theoretical research work into a particular function system. The project construction of automatic fence light controller has been done primarily as a photo type design it could be further modified suit the situation where it will be ...

ABSTRACT This project intended to simplify the description and working principle of FM wireless microphone, which works on a fixed frequency modulation (FM) band. CHAPTER ONE INTRODUCTION  Electronics deals with current flow and the application therefore current is established by movement of electron-hence electronics. Electrons on their own are constituent of the atom. We shall bargain therefore by considering our need for electronics in every day activities because to has ...

ABSTRACT This project report is a thesis written specifically to cover the design analysis construction, test and packaging of a multipurpose security system from electric component that can be easily be obtainable from the market. The report discusses the various unit and stages of the alarm system, thesis include:- a) Clock generation and frequency division unit. b) The control and section unit, comprising of a one shot 555 timer multiplexer, ...

ABSTRACT This project which consists of four chapters deals extensively with the design and construction of a battery charger which is capable charging a 12 volts, battery. The first chapter which is the introductory chapter goes a long way in defining the battery charger and explaining of the mode of operation. The second chapter went further to explain each component part of the battery charger. This ranges from:- 1. The ...

ABSTRACT The project work is on the design and construction of automatic two lane traffic light control. This system is based on digital electronics. It employs an astable multivibrator which is the clock generator that sends the clock into a time sequencing generator using a decade counter with ten (10) decodes output that has it’s binary corded decimal (BCD) output into a diode or gate that sends logical data’s into ...

ABSTRACT The practical importance of a battery charging unit in today’s world cannot be over emphasized. This is so since these batteries or accumulators are immensely needed by automobiles and in science laboratories. This thesis describes the methodical approach to the design and construction of any battery changer. However the procedure developed cover the construction of battery charger for battery sizes ranging from 6 volts to 12 volts. The phototype ...

CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF STUDY As the growing population of human race widens the gulf between energy supply and energy demand, the imbalance in energy availability sent researchers into excavating for a way of settling this age long squabble. A lasting solution is vested on alternative use of the renewable energy source, a project that is yet to be widely applied. Hence, the continuation of the unsettled yearns ...

ABSTRACT This project is design and construction of a sound detector with alarm system was done primarily to detector sound. It can be use in industrial and domestics. It employ four discreet stages with power supply which power the system. The 1st block is pick up amplifier containing the microphone and the input which serve as a transformer which the function is to pick up the smallest sound that comes close ...

Chapter One Introduction Technologies are developing at a high rate during the last century. Computers become smaller, and their potential, on the other hand, grows more prominent each day. As a result, there is a massive movement towards automation in all areas of our lives. This movement has played a vital role in the formation of the Internet of things (IoT) concept , which became the main inspiration for this ...

ABSTRACT The design and construction of 1000VA Automatic Voltage Regulator is made to power our Electrical and Electronic devices, supplying them with the normal output voltage which ranges from 100V- 240v irrespective of the constant voltage and current fluctuation, failure and instability. This project helps the society in many ways which include the stepping up and down of voltage in order to avoid destruction and at is used to vary ...

ABSTRACT A battery charger is an electrical device employed for charging batteries.  This batteries that are usually charged by battery changer are the storage battery charger are the storage batteries also known as “accumulator” the battery changer changes.  The alternating current form the power line into d.c suitable for charging. When the battery is fully changed, is up to it’s maximum, 12 volt, the charger with automatically stop changing with ...

ABSTRACT This is a technical report presented on the design and construction of an Automatic Three Phase Selector. In the construction work, an ordinary level knowledge of electronics principles are observed. We aimed at presenting a practical aspect of the subject and then providing the argument necessary for a thorough understanding. The reliability of the specimen was estimated after construction and testing to ensure steady state stability. The work is ...

ABSTRACT An inverter is an electronic device that converts direct current (DC­) to alternating current (AC) the converted Ac can be at any required voltage and frequency with the use of appropriate transformers, switching and control circuit. It’s simple put, is an electronic box that makes household electricity for everyday items.  It converts power from eg car batteries, windmills, solar panels or fuel cells, then turns it into normal household ...
