ABSTRACT Digital electronics is now used in all fields of electronics from computers to digital phones and most industrial machines and motor vehicles. When prototyping digital electronic circuits, specific digital input signals are required to design the digital circuit. To accomplish this task, a teaching device known as a “Digital Trainer” is utilized. The purpose of this project work is to provide a method for students to test digital circuits, with a simple and inexpensive digi...
ABSTRACT This project work is focused on the design and construction of obstacle detection system for the visually impaired. This paper reports on a study that helps visually-impaired people to walk more confidently. The study hypothesizes that a smart walking stick that alerts visually-impaired people over obstacles in front could help them in walking with less accident. The aim of the paper is to address the development work of a walking stick that could communicate with the users th...
ABSTRACT Since one of the problem of our country Nigeria has been inconsistency power supply, as many business center today depend on computer controlled system, high technology equipment and needs a precise and constant power supply. This work is focused on the design and construction of uninterruptable power supply due to the rising domestic and commercial need for additional back-up source meant to minimize the problem associated with processing, disruption and distribution of val...

ABSTRACT Blender 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: The production of preliminary drawings with detail...
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 be converted to energy (electricity) using different technologies including collecting and converting current landfill gases, wet or dry anaerobic ...

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...
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 parts ...
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 ...
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 ...
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...
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...
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...
