DESIGN AND CONSTRUCTION OF A 60AMP THREE PHASE AUTOMATIC CHANGE OVER SWITCH.

ABSTRACTThe design and construction of a 60A, 3-Ф automatic power changeover from public utility supply to generator and vice versa was aimed at providing a useful system for use in our homes or offices. The system was achieved with a 66A 3-Ф contactor, 100mA transformers and relays. The system turns on a generator when the public utility (PHCN) is off by cranking the starter and a provision was made to stop cranking when the generator is fully started. A delay was provided to stop the gene...

DESIGN AND INSTALLATION OF 200 WATT SOLAR POWER SYSTEM

ABSTRACTThe 200W solar system was determined by load assessment, solar panel number determination, battery requirement and then inverter sizing. A complete solar panel rated at 200w was however purchased, together with 2 no. 150A solar battery, 1500W inverter and also 10A charge controller. These were assembled together with necessary protective gadgets like cut out switches; to give the 200W expected. The solar panel was mounted outside the building to allow for maximum collection of sun ene...

DESIGN AND CONSTRUCTION OF 20WATTS WIRELESS PUBLIC ADDRESS SYSTEM

ABSTRACTIt has become inevitable that there would be communication and due to the inherent limitation of the human voice, the public address system came to being. A public address or “P.A SYSTEM” is an electronic amplification system with a mixer ,amplifier and loudspeakers, used to reinforce a given sound , e.g a person making a speech, pre-recorded music ,or message and distributing the sound throughout a venue . The voice signal is passed through a microphone , which converts the sound...

DESIGN AND CONSTRUCTION OF AN INVERTER TYPE ARC WELDING MACHINE

AbstractWelding is a way of heating pieces of metal using electricity or a flame so that they melt and stick together. It can simply be defined as the process of joining two or more pieces of metal to make the act as a single piece. This is often done by melting the work pieces and adding a filler material to form a pool of molten material that cools to become a strong joint. Because of its strength, welding is used to join beams when constructing buildings, bridges and other structures. Weld...

DESIGN AND CONTRUCTION OF AUTOMATIC PHASE SELECTOR

AbstractAs 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 for sufficient power. Consequently, the power lines are frequently over loaded resulting to a trip of po...

PATIENT HEARTBEAT AND TEMPERATURE MONITOR

AbstractHeart beat rate means the number of heartbeats per unit time, usually expressed as beats per minute (bpm). The human heart pounds to pump oxygen rich blood to the muscles and carry cell waste products away from the tissues. Heartbeat rate can vary according to the demand of the muscles to absorb oxygen and excrete carbon dioxide changes such as during exercise or sleep. It also varies significantly between individuals based on age, fitness and genetics. This means that the heart must ...

HOME CONTROL SWITCH AUTOMATION USING GSM COMMUNICATION

ABSTRACTThe advantage of cellular communication like GSM technology is a potential solution for such remote controlling activities. GSM-SMS technology can be used to control household appliances from remote places. Remotely, the system allows the home owner to monitor and control his house appliances via his mobile phone set by sending commands in the form of SMS message and receiving the appliances status as well. This system provides ideal solution to the problems caused in situations when ...

CONSTRUCTION OF MICROCONTROLLER BASED VEHICLE SPEED ALARM.

ABSTRACT The project is based on Construction of microcontroller vehicle speed alarm system which automatically warns the driver by activating a panic alarm which is triggered on when the driver exceeds the speed limit set in the system which also stops the alarm when the speed is reduced below the set speed limit. A speedometer system is used to monitor the speed of the car. The voltage output of the speedometer system is used to set the time the alarm comes on. The other component part...

CONSTRUCTION OF MICROCONTROLLER DOT MATRIX DISPLAY SYSTEM

ABSTRACTThe microcontroller based display board is an advert system that displays information based on a specific purpose. The system is designed to enable the viewer know the designers aim.The system comprises of different blocks of functional circuit that are put together to achieve the desired aim. These blocks include; the power supply section, the control section, the demultiplexer section and the display unit. The power supply unit is the section of the system that ensures that the syst...

CONSTRUCTION OF A BLENDER

ABSTRACTBlender is an electric machine for size reducing soft food or liquid mixture.  Blender is some time called liquidizer consists of a glass jar or jug containing a steel blade assembly at the base driven by a small electric motor.Construction of blender was done based on the principle of size of reduction using electric motor as the major driver force.  During the construction of blender, we adopted different stages which includes:i.    The production of prelimi...

WASTES AND SEWAGE AS A SOURCE OF ELECTRICITY GENERATION

ABSTRACTWaste and residuals are undeniably part of the human society. The accumulation of these materials and the “throw away” philosophy results in many environmental and health issues and safety hazard problems prevent sustainable development in terms of resource recovery and recycling of waste materials. The carbon sources in the waste can be converted to energy (electricity) using different technologies including co...

EVALUATION OF THE EFFECTS OF FLOODING ON FOUR VARIETIES OF RICE (A CASE STUDY OF EZZA NORTH, ABAKALIKI, EBONYI STATE)

ABSTRACTFlooding has been described as one of the most important environmental factors determining the distribution of salt maize plants. We studied the impact of five water levels on the germination and establishment of the invasive cord grass spartina denifora. Plant house experiment was carried out to determine the effects of time and depth of flooding o the survival and growth of rice. Data showed that time and depth of flood had significant effects on the survival and growth of rice.&nbs...

DESIGN AND FABRICATION OF WHEEL AND BRAKE SYSTEM OF A TIPPING TRUCK

ABSTRACTThe purpose of this research work is to design, fabricate and install a hydraulic brake system on a wheel system of an agricultural tipping truck. For an efficient functioning of the brake system some measures have to be strictly considered; the weight of the vehicle and the external load.The engineering materials used in the fabrication of the wheels system include metals, ceramics and polymerics.Despite the efficiency of the brake there must be routine checks and maintenance to ensu...

DESIGN AND CONSTRUCTION OF FOUR-WAY TRAFFIC LIGHT

ABSTRACTThe project “microcontroller based intelligent traffic light system with automatic street light and warning light” was designed to tackle the traffic issues in the country so as to establish automatic traffic control and monitoring system with near perfection. The project intelligent traffic light with automatic street light and warning light is a complex microcontroller based project that was designed to control traffic on a four way road network.The system is embedded with ...
