ABSTRACT Waste 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... Continue Reading
ABSTRACT A traffic light also known as a traffic signal, stop light and go light, robot or semaphore is a signally device positioned at four (cross) junction, pedestrian crossing or other locations in other to indicate when it is safe to drive or walk using a universal color code ( and in precise sequence for those that are color blind). Traffic... 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...

ABSTRACT The Orsat Gas Analyzer was constructed at the project development institute (PRODA), Enugu. The operation involved the laboratory glass blowing which entails the heating of a glass tube. The heating •continues until the glass tube reaches its plastic state. The shape of the tube is changed or the required shape blown by pulling, bending... Continue Reading
ABSTRACT The motive of this project is to construct equipment for deodorizing kerosene, hence the smell of kerosene is totally eradicated. The equipment was constructed with flat sheet plates of a desired standard, the dimension and the truncated parts were coupled and welded in order to fasten the parts together. The material was selected to... Continue Reading
ABSTRACT This project involves the development of a console that allows multiple inputs (3 inputs) and a single output to a screen through the use of software. The micro controller which serves as the ‘heart’ of the hardware was encoded using C programming language. These lines of code enable the micro controller to switch to the selected...
