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,...
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 (...
AbstractThe uninterrupted power is only dedicated for the purposed of illumination. Light is so important to man, so there is need to build an emergency lightening system to help reduce the problem encounter due o frequent interrupted power failure. This is reason for this project report which is CONSTRUCTION OF AUTOMATIC EMERGENCY LIGHTING SYSTEM. These project forms a stand-by source of light energy to man, it operates with the principles that when there is power failure the system will aut...
ABSTRACT This project topic “Secured Wireless Network” was carried out with a view to deploying effective security for wireless networks. The project developed a system that lets typical users easily build a highly secured wireless network. My aim is to show how user interface can be applied to provide a complete solution for securing wireless networks. Securing a wireless network is an important issue since they are wireless broadcasting a signal out over an area, any computer within t...
Quiz buzzers are used often at places like educational institutions where it is required for game shows and also in live quiz competitions broadcasted via television. A quiz buzzer allows any user to press the switch quickly in response to a question posed during competitions that are conducted in schools and colleges. The pressed switch gives a buzzing sound or alarm for some duration of time and the reaction time is very small. Buzzer can also be used in different applications such as annun...
In democratic countries, voting is an vital tool to collect and re-act people‘s views. In the elections, the election of member of the assembly, the head of local/state government election, and others, a voter can cast vote after going to the designated polling place and checking his identity. Conventionally, voting booth is used for casting votes in both centralized and distributed places. Voting is done under the supervision of authorized parties. Counting of votes is done manually once...
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...
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 fre...
ABSTRACT The increasing rate of crime, attacks by thieves, intruders and vandals, despite all forms of security gadgets and locks still need the attention of researchers to find a permanent solution to the well being of lives and properties of individual. To this end, we constructed a cheap and effective security system for buildings, cars, safes, doors and gates, so as to prevent unauthorized person from having access to ones properties through the use of codes, we therefore experiment the a...

ABSTRACT The consumptive use of water assures all year round production of groundnut prone to the vagaries of weather and climate. This brought about the need to supply moisture that is naturally available through rainfall. The successful design of any irrigation system requires the knowledge of the consumptive use of water by the crop under consideration. This need led to the investigation of the water use rate of groundnut in a typical area found in Awha-Imezi of Ezeagu in Enugu State ...
ABSTRACT The motorized cassava peeling machine is a type of cassava peeling method that is adopted to reduce drudgery. In cassava peeling operations. This method, unlike the manual peeling method which consumes a lot of human power with subsequent low output produces or peels a large amount of cassava tubers within a small specific of time and small amount of flesh loss and finally low demand of power. this paper presents the design and constructing of a motorized cassava peeling machine th...
ABSTRACT Power interruption and failure does not promote development. Investors and private organization do not feel secure to establish a business in a country with constant or frequent power failure. Power interruption limits the development of industries, commerce, businesses and seriously effects the economic development of any nation. There are vital jobs or processes that cannot be interrupted due to their importance, for instance surgery operation in hospitals, transfer of money betwee...
