ABSTRACT The problem of epileptic power supply and its consequences in the developing countries is a generally known issue. Worst still, the hope that it will be addressed with the deregulation of electricity Industries in recent time are being dashed by flight to top class investors due to its poor implementation. There is a need to provide... Continue Reading
Abstract This temperature control fan can be controlled using a microcontroller when it detects a certain temperature that has been set. The purpose of this project is to prevent the waste of voltage usage when it is not hot enough for fan to be needed. The temperature control fan has three different speeds. Each... Continue Reading
The household lighting cost accounts for 10% of the electric bill, changing the light bulbs effectively can reduce the long term energy costs significantly. In Nigeria, where less than one percent of the population has access to 24 hours of interrupted power supply there is a need for a complementary, renewable source of light which provides...

So as to amplifier an output, the general construction dealt with in the chapters. The levels of... Continue Reading
ABSTRACT 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... Continue Reading
ABSTRACT An 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... Continue Reading
Abstract 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.... Continue Reading

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... Continue Reading

ABSTRACT It 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,... Continue Reading
Abstract Traffic management systems at road intersections of most African cities is based on fixed timings where equal length of green light is assigned to each lane at the intersection. This method of traffic management is inefficient because it causes unnecessarily long waiting times for vehicles at the intersections especially during periods... Continue Reading
