CONSTRUCTION OF AN FM TRANSMITTER

ABSTRACT  This project work is on the construction of an F.M transmitter this system consists of four discrete modules namely the audio frequency (AF) amplifier (class A) the modulator the master oscillator and the radio frequency (RF) amplifier (ClassC) these formed the conventional events for building FM transmitter here the signal (from the microphone) is fed into the (AF) for amplification then to the modulator which combines the modulating signal with the carrier wave transports the mod...

CONSTRUCTION OF A BATTERY CHANGER USING SILICON CONTROLLED REGULATOR (SCR)

ABSTRACT  The practical importance of a battery charger in today world cannot be over emphasized. This is so as those batteries accumulators are immensely needed by out auto mobile and in science laboratories. This thesis describes the methodical approach to the design and construction of  any battery charger. However the procedure fro developed cover the construction  of battery charger for battery sizes ranging from 6 voltage to 24volatge (heavy duty) batteries. The prototype of a batter...

CONSTRUCTION OF 150 WATTS 162 AUDIO LOUDSPEAKER

ABSTRACT  Audio loudspeaker (output transducer) is on of the most essential and powerful device used in telecommunication system. This is device capable of converting electrical signal into sound and vice versa. It is made up of few time of non-magnetic wire wound on a light cylindrical former that is mounted so that it can move freely insides the magnetic field of a strong permanent magnet. The speaker cone it attached to the voice coil and attached with a flexible mounting to outer ting of...

CONSTRUCTION AND IMPLEMENTATION OF 6V ECHARGEABLE LAMP

ABSTRACT  Researchable lamp is a source of light that is generated from a D.C sources of supply this D.C sources is a battery that can also way be charged when it current and voltage ruse I decided to work on this as my project because its importance. It is very portable and help the a lot during night reading  It also serves as an immanency sources of light mostly when there is failure from out public power supply (P.H.C.N)    TABLE OF CONTENT Title page Approval page Acknowledgement Abs...

CONSTRUCTION AND DESIGN OF A 6V RECHARGEABLE LAMP

ABSTRACT Man has been so used to electricity that he cannot do without it. The absence of electricity causes a lot of sadness in our daily lives. Due to this reason I decided to work on a by rechargeable lamp as my project. The project is to see how one can construct a source of high without really generating is from an A.C source. I decided to write on this project in order to saw how I can implement it during and after school for home and marketing purpose. This project is a lamp that was a...

DESIGN AND CONSTRUCTION OF AN AUTOMATIC CHANGEOVER SWITCH

ABSTRACT The main aim of any electric power supply in the world is to provide uninterrupted power supply at all times to all its consumers. Although, in developing countries, the electric power generated to meet the demands of the growing consumers of electricity is insufficient, hence power instability and outage. Power instability or outage in general does not promote development in the public and private sector. The investors do not feel secure to come into a country with constant or frequ...

Ultrasonic Object Detection

Ultrasonic Object Detection Project The main aim of this system is to detect object that will be ahead of ultrasonic transducer. This application is very useful in areas like monitoring and also very useful in wild life photography. There are two main parts of the ultrasonic detector. First one is emitter that produces a 40kHz sound wave. Second one is detector that helps to detect 40kHz sound wave.  This signal is then sent back to microcontroller. In this system the ultrasonic module is...

User programmable door lock

ABSTRACT This project report describes the design and construction of an electronic door lock which uses a microcontroller as the main control unit. The project’s objective was to interface this microcontroller with an LCD, keypad and a DC motor. However, programming the PIC chip to perform a task like identifying an authorised user is also among the objectives of this project. Codes were developed in assembly language, complied, debugged and downloaded to the PIC microcontroller. These cod...

DESIGN AND CONSTRUCTION OF ELECTRIC OVEN

ABSTRACTAn oven is a heated enclosure for heating, baking or drying. An electric oven is a heating device used to heat materials to high temperature when electric current is passed through a high resistance heating element (coil or plate). Electric ovens can fine their application in many fields and area of discipline like factories, research institutes, school, medical outfits and general laboratory, but more widely used in food industries. In this project many components: diodes, resistors,...

CONSTRUCTION OF POWER OUTAGE ALARM

ABSTRACTThis work is a power supply monitoring device that triggers a buzzer when the mains supply cuts off. Thus a diode (bridge rectifier diode) was used to convert the AC voltage to DC voltage and the 240v/12v AC mains power transfer was used with a bridge rectifier for rectification and a 470Nf filter capacitor C1 for the smoothing of the voltage. A transformer for stepping down the 240volts was also used before it was rectified. Resistor R1 for reduction of the voltage to power the LED (...

DESIGN AND CONSTRUCTION OF A SINGLE PHASE MICROCONTROLLER BASED AUTOMATIC CHANGEOVER WITH GENERATOR STARTER

ABSTRACT Most industrial and commercial processes are dependent on electrical power. Power failure or outage in general does not promote development in public and private sectors. The investors do not feel secure to come into a country with constant or frequent power failure. This limits the development of industries.In addition there are processes that cannot be interrupted because of their importance, for instance surgery operation in hospitals, conducting research, transfer of money betwee...
