In this current situation, the degree of security is feeble. So there is a lot of robbery, theft going on in and around the world. So, people fear to keep any of their valuables in their homes. Henceforth, many people prefer to keep it in banks. However, in this insecure world even banks are not too safe enough to satisfy people needs. A… Continue Reading
This research work designs a wireless power transfer system (WPT) for non smart phones as an alternative to existing wired power supply systems for these devices. Initially, the general concept of known WPT systems and methods are introduced and reviewed. It was noted that most existing WPT models do not consider external interferences in… Continue Reading
A digitally controlled light dimmer circuit is based on the principle of power control using thyristor. The switch enables light from an electric bulb to be raised from full brilliance down or up to a high range of luminance. Owning to its construction, adequate conservation of energy is achieved. The circuit is made in… Continue Reading
Security is one thing human should not joke with, especially in today’s world where crime is at a higher rate. One of the ways of providing security is the introduction of security doors in houses, companies, offices and warehouses. Security doors may prevent or control entry or exit, or they may be merely decorative. Larger doors can… Continue Reading
In the study of the influence of saliency ratio (L /L ) on the performance of a synchronous reluctance generator (SRG), this project investigates two typical generator rotor designs: Generator with cage and without cage otherwise known as cage and cageless rotor respectively. A special attention had been paid to the possible rotor… Continue Reading
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
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… Continue Reading
The 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… Continue Reading
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… Continue Reading
The 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… Continue Reading
Heart 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… Continue Reading
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
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… Continue Reading
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
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… Continue Reading
The design and construction of a 60A, 3-Ф automatic power changeover from public utility supply to generator and vice versa was aimed at providing a useful system for use in our homes or offices. The system was achieved with a 66A 3-Ф contactor, 100mA transformers and relays. The system turns on a generator when the public utility… Continue Reading
A wireless signal jammer is a device which blocks transmission by creating interference. This wireless signal jammer can be categorized into the Radio Frequency (RF) jammer and GSM jammer. A Radio Frequency jammer is a device used to disrupt or prevent communication via a broadcasted RF signal. It is an RF and GSM frequency disrupter… Continue Reading
Automatic water level controller for both overhead and underground tank is designed to monitor the level of water in a tank. It displays the level of water and when it is at the lowest level; a pump is activated automatically to refill the tank. When the tank is filled to its maximum capacity, the pump is automatically de-energized.… Continue Reading
T-junction traffic light controller is such a device that will play a significant role in controlling traffic at junctions, to ease the expected increased rush at such junctions and reduce to minimum disorderliness that may arise, as well as allowing the pedestrians a right of the way at intervals rather than being struck down when in a… Continue Reading
With advancement of technology things are becoming simpler and easier for us. Automatic systems are being preferred over manual system. The purpose of this project is to design and construct A GSM based home automation using AVR. Using GSM networks, in this project a home power control system has been proposed that will act as an embedded… Continue Reading
Metal detectors are electronics sensors that indicate the presence of metallic object without making physical contact with object. They are effective and useful security tools employed in strategic places such as airport, bank, stadiums, government houses and also in production industries to detect presence of metallic object on person… Continue Reading
Microcontroller based automate controller is a project design of a system that is used in operating a gate automatically. The system opens the gate automatically when a human being or car is about to enter a compound or exit a compound. The system works by sensing the light rays from the head lamp of the vehicle. The light ray is sensed… Continue Reading
