The 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 b […]

The sole aim of this research work is to produce a high quality of bar soaps and compare with detergent. The major aspects of this projects deals with quality control processes in the production of a high quality bar soaps. In soap production, cold process was used and this was found out to be the most effective means of production considering several factors. In the production of bar soaps, palm kernel oil was used instead of fallow […]

INTRODUCTION 1.1 THE BACKGROUND Welding 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 […]

This project “The Production of Ceiling Board from Local Raw Materials” was carried out basically using raw materials which was sourced locally. These raw materials are found to be very much in abundance. Some are materials sourced from the ground and others are from agricultural wastes. Three different types of ceiling boards were produced, their difference being in the type of fibre that was used. The fibres used for this different […]

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 people. It is designed in such a way that it will take up 12v DC from battery and inverts it to an […]

INTRODUCTION All modern engineering system include certain aspects of control systems at some point in their broadcast sense, control engineering and the associated theory are concerned with the means by which systems may be made to behave an a desired way. The system on this thesis is a DC – AC converter, which is an apparatus which is used for conversion of Direct Current to Alternating Current or signal. In our country, this equipme […]

A 1.25KVA (2000W) inverter generator was designed, constructed and certified Ok. In this project, the design of the inverter generator is aimed at satisfying the need of converting, a D.C source of supply (12v battery) to an A.C voltage of 220v. The inverter range of output is between 200-220v. Since the inverter was designed to step-up voltage, the power transformer is being used as step-down transformer for charging and as step-up tr […]
