ABSTRACT Automatic voltage inverter is an important area in power system engineering. It is the process of using a 12v DC from the battery to achieve a 220/230V AC through the help of oscillator, drivers, power transistors and transformer. The stages are battery to oscillators, oscillators to drivers, drivers to power transistors then from power transistors to transformer which is capable of giving out 220/230V (1000w) as an output. A 1.25KVA (1000w) voltage inverter was construct...
Abstract A smoke detector is a device that senses smoke typically as an indicator of fire or non- smoking zone. In order to ensure human safety and safeguard property against fire in both domestic and commercial settings, different solutions for smoke detection have been developed, a comprehensive literature was carried out on smoke detector, this project describes the construction and design of a micro controller smoke detector, it discusses the components used, design methodology and test...
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 enough illumination at a reasonable price, with assured safety using it and also using for a long duration of time before the need to replace it. Recentl...

ABSTRACT The Airbeetle-18 unmanned Aircraft is an Aircraft design for the purpose of surveillance following the fact that the parent Airbeetle-18 has almost reached the end of its life time. Hence, there is need to convert it to an unmanned aircraft in other to extend its service life time. A comprehensive literature review was carried out on Telemetry and power system design and the previous work done as it pertains to aircraft in Airbeetle-18 category. Furthermore, system requirement ana...
Abstract This project work centered on construction of 12V/10A solar charge controller that is needed in photovoltaic system to safely charge regulate and discharge of sealed lead acid battery through DC load. Solar charge controller is devices that regulate solar photovoltaic power and prevent overcharging, over discharging or overflow of current that reduces the lifespan, durability and performance of the battery. The12v/10A solar charge controller was constructed using variable resistor, ...
The aim of this project is to shows the possibility of wireless power transfer through the design of a wireless charging pad. In this project write-up, the methodology and principle of operation is wireless power transfer through inductive couple, a feasible design is modelled accordingly. The inductive couple technique is used because it is the easiest method of wireless power transfer with high efficiency and large amount of energy transfer. This report showed the versatility in range of a...
Abstract This project work was embarked on the construction and determination of the efficiency of 12 volts DC fan using two N3055 transistor, 1kΩ variable resistors, resistors, breadboard, veroboard, 12 volts DC battery and connectors at Science Laboratory Technological Department, Federal Polytechnic Offa, Nigeria. This is always required to minimize, control or totally eliminate the power fluctuations received at the load end or consumer end that usually lead to the reduction of DC fan li...
ABSTRACT In our present society, wireless communication has become most prevalent and mobile units (hand held devices /GSM/ Computers) are one of the most common equipments for conveying messages wirelessly. Owing to the fact that most youths in our society today on the average make use of at least one wireless device that communicate with other wireless devices via the internet, has made engineers start to think about ways to improve the quality of service (QOS), throughput, spectral effic...
ABSTRACT-Power system planning is a vast and important issue for operation and expansion of power delivery. One of the basic objectives of planning is to determine the right schedule for investment in new devices which ensures secure and economic power delivery for predicted customer demand. System planning also addresses the question of reliable and stable operation; hence reliability and stability analysis are also included in adequate power system planning studies. This work explores the a...

ABSTRACT The need for a remote control system that can control domestic appliances and various lighting points and sockets has often been a concern for uses at times uses find it inconvenient and time they are leaving the house for work it has also often led to damage of appliances due to the fact that an appliances was not timed off before leaving the house. The objective of putting up. This project therefore is to design equipment that can facilitate a convenient and easy way of controllin...
ABSTRACT The design and construction of the House Bell with indicating light system was creative embarked on for the production of a better alarm signals. Meanwhile different measures and steps such as using electric bell, electric bulb, light emitting diode, 1 mm2 their cable, B Amps plug, lamp holder was used to achieve the objective. All the measures that were taken to ensure the functionality of this project were discussed in detail. Finally, conclusion and recommendation that will en...
ABSTRACT The very fundamental reasons behind this project assignment is to expose student to the very important aspect of private and independent research work not only theories but also subsequent translation of the theoretical research work into a particular function system. The project construction of automatic fence light controller has been done primarily as a photo type design it could be further modified suit the situation where it will be used e.g when used to activate an alarm the ...
