Design and Implementation of a Software Intercom on LAN

ABSTRACTIn a developing economy like Nigeria financial resources are scarce commodity. Hence, cheaper means of accomplishing tasks even within the presence of scarce resources are always explored.This paper presents the design and implementation of a software intercom on local area network (LAN). The design provides a solution that eliminates the use of expensive hard-wired intercoms and Private Automatic Branch Exchange (PABX) by making use of only LAN and full multimedia computer allowing n...

DESIGN AND CONSTRUCTION OF FOUR-WAY TRAFFIC LIGHT

ABSTRACTThe project “microcontroller based intelligent traffic light system with automatic street light and warning light” was designed to tackle the traffic issues in the country so as to establish automatic traffic control and monitoring system with near perfection. The project intelligent traffic light with automatic street light and warning light is a complex microcontroller based project that was designed to control traffic on a four way road network.The system is embedded with ...

DESIGN AND IMPLEMENTATION OF ONLINE VOTING SYSTEM INCORPORATING FINGER VEIN SENSING

ABSTRACTVoting is a very important process in the Nigerian political system.  It is one of the means and most effective method of ensuring a legitimate government through popular participation.  To enthrone sound democracy and stability in the political system in Nigeria, a system of rig-free voting has to be put in place. Online voter registration systems supplement the traditional paper-based process, by which new voters fill out a paper form that is submitted to election official...

A GSM BASED HOME AUTOMATION USING AVR

ABSTRACTWith 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 system which can monitor and control appliances and other devices locally using built-in input and output peripherals. The system has a delay of 2 m...

CONSTRUCTION OF A MICROCONTROLLER BASED T-JUNCTION TRAFFIC LIGHT CONTROLLER

ABSTRACTT-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 hurry to cross the roads. Such an electrical system with a touch of electronics that control the flow of traffic in a pre-determined sequential patter...

CONSTRUCTION OF AUTOMATIC WATER LEVEL CONTROLLER FOR BOTH OVERHEAD AND UNDERGROUND TANKS

ABSTRACTAutomatic 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. Several circuits are put together to ensure proper working of this design, and the block diagram includes the supply unit, the micro-processor unit, the s...

CONSTRUCTION OF RADIO FREQUENCY GSM SIGNAL JAMMER

This project is mainly intended to prevent the usage of mobile phones in places inside it coverage without interfering with communication channels outside it range, thus providing a cheap and reliable method for blocking mobile communication in the required restricted area only. Although we must be aware of the fact that nowadays lot of mobile phones can easily negotiate the jammer effect are available and therefore advance measures should be taken to jam such type of devices. The main disadv...

Design And Construction Of 20 Watts Wireless Public Address System

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 ...

Design And Construction Of An Inverter Type Arc Welding Machine

The main aim and objective of this project is to design and build and arc welding machine that operates on 36vdc at variable frequency which of benefit to urban area. This reduces the weight and size of the transformer use for welding. To have an arc welding machine that is more efficient which produce neat welding.INTRODUCTIONWelding 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...

Design And Construction of Automatic Phase Selector

The scope of the project covers aspects like the features of automatic three phase selector, its applications, and its operations. Its advantages and its components. Finally, it covers the importance on the need of automatic three phase selector and contributions toward a greater sharing load balance and a better three phase power distribution and monitoring for domestics consumers.INTRODUCTIONAs the growing population of human race widens the gulf between energy supply and energy demand, the...

Home Control Switch Automation Using Gsm Communication

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 ...

Design Of A Patient Heartbeat And Temperature Monitor Using RF

The major aim and objective of this design [of a patient heartbeat and temperature monitor using RF.] is to help the doctors and family members to keep track of the heartbeat condition of their loved ones [as well as their body temperature] in the case of an abnormality in the health condition (for those with heartbeat defects and those that run excessive high temperature beyond normal). If any varied change takes place, it is notified. This notification through RF. Channel would to take an a...

Design and Construction of an Automatic Power Changeover Switch

AbstractPower failure or outage in general does not promote development to public and private sector. The investors do not feel secure to come into a country with constant or frequent power failure. These limit the development of industries. In addition there are processes that cannot be interrupted because of their importance, for instance surgery operation in hospitals, transfer of money between banks and lots more. This paper presents the design and construction of an automatic power chang...

DESIGN AND CONSTRUCT A MULTIREMOTE CONTROLLER USING INFRA-RED MODE OF TRANSMISSION

ABSTRACTMicrocontroller based remote control system is a project design of a system that uses infra red transmission and reception principle to switch on or off other appliances. It is a wireless mode of switching appliances to a desired state. When a number is pressed in the transmitter section, the receiver section decodes the signal and utilizes it in controlling the desired appliances.Several functional blocks of circuit are put together to ensure that the design works as the designer int...
