INTRODUCTION Emergency light is an integral part of household electronics nowadays. We all Emergency light is used during the power failure to light up the home. As it is used during the power failure, it should last long, hence generally bright white LEDs are used in emergency light, because they produce more light and consume less power. Emergency light is very useful and popular project in DIY section. So today we are going to build a simple and cost effective emergency light. In this emergency light circuit, when the Power goes OFF, the emergency light activates automatically. We have used four bright white LEDs; more LEDs can be added to produce more light considering that total current consumption should not exceed the supply current. Ultra bright white LED consumes 3v and 20mA current. 1.2 OBJECTIVES -To design a project that can be used an alternative source of light in case of power failure occasioned by changes in climatic conditions. -To design a project that is cost effective. 1:3 SPECIFICATION -Input voltage (220-240) V arc -Frequency 50Hz a.c -Battery output voltage 6v d.c -Output current 4.5Ah 1:4 PROBLEM STATEMENT - In boarding school at night and dawn studies, students do have problems when their is power failure ,so I come up with this project that will help provide light to them during their studies incase of power failure.. - Lastly it helps to reduce the cost of power consumption, hence it's economical alternative source of power,, as compared to generator.

ABSTRACT Umbwa Kali car wash is facing a problem of poor management and the sharing of information with its customers. All activities and services advancement reports in Umbwa Kali Car Wash are done manually; and this causes a waste of time and outperformance of the car wash. The purpose of this work is to design and implement a web based application which will help this car wash to manage all problems relating to the communication between customers, employees and car wash staff. This application offers the ability of communicating with customers and car wash management quickly. It also offers the owner of car wash the ability to view all activity processes done by managers on daily basis through bill reports. For the development of this project two methodologies will be used: the research methodology and the software engineering methodology. Research methodology consists of interviewing and reviewing and the literature necessary to carry out this study. The population of this study is 60 including 40 employees of the carwash and 20 customers. Employees are many compared to customers because most of time customers are used to leave their car to the car wash to pick them back when they have been cleaned, this was the main challenge to the researcher because to find customers present to the car wash was not easy.

ABSTRACT This project explored the relevance of management systems to the contemporary society where computers have made tasks easier, more efficient and organized. Police record management system is a planned system of the storage processing and dissemination of data in the form of information needed to carry out various functions which come to simplify the tiresome manual way of reporting and writing the details on papers. There is need for an computrised record management system that can be used to store reported criminal activities in a centralized database which should replace the manual system that is currently being used. The manual system has few challenges that include the ever increasing paper load, difficulty in enforcing access control as well as cases of missing files and information. Our objective in regard to the project is to come up with an application that will be used to automate the manual management of Kenyan criminal records and hence the title “police management system (PRMS)”. Being a web based application; there is an assumption of users being connected to the internet. The scope of the project cuts across administrators and 2 types of clients; police officers and other clients: including private investigators, lawyers and other personalities seem fit by the Administrator to handle an account. The research methodology used in this project was System development lifecycle, using waterfall method simply because the project was small and there are no uncertain requirements. At the end of each phase, a review takes place to determine if the project is on the right path and whether or not to continue or discard the project The design was majorly aided by the dataflow context diagrams which are often used as a preliminary step to create an overview of the system. Use-case diagrams and activity diagrams also helped in coming up with the database class diagram which we used to develop the database. I faced some challenges in developing the systems in terms of having to learn new programming language on a short time frame and also experienced financial constraints on printing and buying of some devices that would have helped me to come up with better system like fingerprint scanner. In conclusion I would like to say that taking this project all through has been a wonderful experience for me. Without the practical knowledge that we acquired throughout the course, this project would not have materialized

Technology development has made automation process simpler. The rise in population in the country increases demand for electrical knowledge, Security personnel and more application of electricity in their lives for better improvement and efficient services in homes and the country at large. The need of security is essential to human and living creatures. Considering the need of security we realized that the level of crimes such as theft is increasing, which causes poverty to low class people and class beings. Security is a vital tool in life as it helps people comfortably do business, live well hence encouraging investment the act of employing people to keep monitoring the area is expensive, Therefore a unit need to be designed to solve this problem. In considering the need of many I care up with infrared Based Security Alarm system which alerts one when the intruder interference with IR. i.e. when someone enters in a given area it turns on the security lamps and hence the Buzzer/ac alarm using Relay can produce sound hence detection at the intruder. Infrared based security alarm circuit an detect any movement trigger the alarm. THIS circuit is very useful in homes, banks, shops restricted areas where an alert alarm is needed on any movement. This circuit is based on IR sensor where an infrared beam is continuously falling on a photodiode and whenever this infrared beam breaks by any kind of movement alarm is triggered. Infrared sensor consist an infrared LED and photodiode in which IR LED emits infrared radiation and photodiode detects the radiation photodiode conducts current in reverse direction whenever light falls on it and voltages across it changes this voltages charge is sensed by voltages comparator i.e.(LM358) and generates output accordingly. In this infrared based security alarm circuit we have placed infrared LED in front of photodiode so that IR light can directly falls in photodiode. Whenever someone moves through this beam IR rays stop falling on photodiode and Buzzer start beeping . Buzzer automatically stops after sometimes as buzzer is connected to 55 timer in mono stable mode. OBJECTIVE Main objectives To design infrared based security alarm.

ABSTRACT Conductor failure or outage in general does not promote development to public and private sectors. Development of our country and in addition, there are processes that need not to be interrupted because of their importance. This project presents the design, construction and implementation of a broken ac conductor for automatic detection of a broken ac conductor. Studies have shown that the electric fault which occurs in this facilities constitute the major cause of service interruptions as a result of their exposure to high currents, mechanical strains, utilization by the high currents consuming appliances used for a long time thus it’s difficult to locate the accurate location of the broken conductor. and because now days’ electric cables are being installed inside the walls using the pvc conduits or are being installed underground by the use of underground cables and because of this people generally replace the broken conductors instead of repairing them due to hardship in locating the exact place where the cable is broken therefore the reason of coming up with this project was to facilitate quick locating and isolation.

ABSTRACT An A.C and D.C fluorescent tube is useful for emergency blackout as it works on D.C as well, this saves the production process under lightings. This project comprises A.C components as well as D.C components under improved conditions, this makes it useful in both urban and rural areas. When A.C power is off user can supply it with D.C power to light the house or place as well Although fluorescent lamp is a very efficient lighting device in daily life, still the high harmonic distortion and low power factor cause unnecessary energy consumption. In today’s environment demanding energy efficiency, it is important to reduce this energy loss by integrating an energy saving controller in the electromagnetic ballast of fluorescent lamps. The research presented in this thesis investigates the design and implementation of a new energy saving controller for electromagnetic fluorescent lamp network. The newly developed controller attempts to reduce power losses in both the electromagnetic ballasts and fluorescent lamps by regulating the incoming supply voltage to an optimum level. In addition, the new controller is able to adjust the illuminance level of working environment lightings under either dark or bright condition. Moreover, the function of the new controller is extended with time scheduling control capability, where the switching of lighting systems can be controlled at predetermined times based on occupancy schedule. Both simulation and practical results show that the implemented controller reduces energy consumption by at least 37.5%, by reducing the incoming supply voltage by 15%. In addition, it is desirable to have variable illuminance level control to decrease the energy losses. The experimental results show that the illuminance output level of electromagnetic ballast fluorescent lamps can be decreased by 50% using the new controller while maintaining unity power factor. Integration of the new energy saving controller into electromagnetic ballast fluorescent lamps impressively outperforms the existing electronic dimmable ballast. This new controller brings great ideas for energy saving in the use of fluorescent lamps. Keyword: energy saving, illuminance level control, voltage control, electromagnetic ballast fluorescent lamps

ABSTRACT The essential use of 12V lead acid batteries in automobile engines to power incorporated electrical appliances, and also the sudden failure of vehicle charging systems that often give rise to a drain of battery cells has necessitated the construction of battery chargers suitable for fully restoring the lost charge into the required 12V battery cells. Most 12V battery charging devices built for commercial services are usually heavy and bulky and lack a protection circuit and a sensitized control circuit required for automatic deactivation of charging once the battery is fully charged. In this new design product, the size of the battery charger was made portable and light in weight to enable end users to convey it as easily as possible. Short circuits and current reverse protection were incorporated as well. A sensitized control circuit was implemented to ensure that charging is terminated immediately when the battery is fully charged. This is to avoid the possible occurrence of overcharging that may result in loss of electrolytes. In this report the components used to actualize the design work were listed and the design specifications were tabulated with the circuit diagram well detailed. The operational principle of the built charger clearly explains how the design objectives were reached. An adopted formula with example on how to calculate the charging time of a battery when using the product was derived. Design limitations, recommendations, and conclusion were stated. Various relevant tests were conducted with its corresponding results tabulated. Finally, a well labeled image which lays out views of the completely constructed battery charger is attached in order to appreciate the effort and the value of the design work. (Keywords: AC power supply, rectification, charging, deactivation, full charge) Considering, the compact shape of the battery charger, with very low ventilation an extractor fan was incorporated to drive away hot air and moisture that would be generated inside the charger compartment during operation.

ABSTRACT The research aims at the designing and implementation of an automatic voltage regulator (AVR) with high precision and hysteresis. The AC power supplied by KPLC (Kenya Power) subjected to variation from time to time. Moreover, in rural areas supplied voltage remains lower than specified. This causes a considerable threat to the sophisticated electronic device to the computer, refrigerator, television etc. So, ensuring the input voltage to remain in a tolerable pre-specified limit has become a necessity in rural as well as some urban areas. Current system available locally lack precision and suffers the problem oscillating between two output voltage and hence creating surge at the output which can damage valuable electronics. This project handles both shortcomings and introduces the tolerable range of 12 1 voltage output. MERIT The circuit is simple but useful for wall AC/DC adaptors where it is important to reduce ripples and noise, and improve transient response of the adaptors. It can also be used in a wide range of switching and analogue power supplies. The circuit has been developed for 26V and 19V wall adaptors, but by replacing some components, it can be used for other wall adaptors with output voltage starting from 5V. When input polarity is fixed, the bridge can be replaced with simple diodes depending on requirement.

BSTRACT The scope of this project is to design, develop and test a power supply capable of taking an ac voltage and convert it into a regulated low voltage. The main working of this project is a full wave rectification which is done by bridge configuration in which four diodes are used to rectify the output the step-down transformer which steps down the voltage from 240v to 12 V.A Voltage Regulator is then used which gives a constant voltage. The main task is to get variable output by using the pair of voltage divider resistance to increase the output of the regulator in which the resistance is variable. So when increasing or decreasing the resistance of the resistor, also the voltage varies from 1Vto 12 V.The circuit also uses capacitors C1 and C2 to get constant input voltage to the regulator and also is used tosmoothen the rectified voltage to output.The power supply will be connected to the Zener voltage regulator that could supply to the load.

ABSTRACT Bus ticketing process in Kenya is one of the slowest and time wasting yet it is the mains means of travel between the capital cities to major towns. Currently use of mobile telephone is widespread and considerable penetration has been achieved. In Kenya the application of bus ticketing system is yet to be explored. This comes in the light that Kenya’s bus travel business has grown steadily over time without matching improvement in ticketing or booking services. For long there has complaints and dissatisfaction among the public because travelers move long distances to book tickets and suffer congestion at bus terminals, unnecessary time wasting as a result of misplaced tickets and unauthorized agents who can cause financial loses. Ticket booking at bus companies is inherently time consuming, inconvenient and sometimes frustrating for time conscious passengers and therefore there is need to develop efficient mechanism that operates through an increasingly available technology like the mobile phone and specifically through a widely used application like SMS. The study examined SMS bus booking reduced terminal congestion, minimize time wastage and eliminate unnecessary expenditure. Bus ticketing is the process whereby customers can order, pay for, obtain and validate tickets from any location and at any time using mobile phones. The passenger downloads the essential program onto his [her mobile phone. This program allows the passenger to press a button to send an SMS to server indicating their travel details (Departure Date, Departure time, Destination Town, Departure Town). for source code contact +254723316663

Sitting in a shop in Tehran, Iran, the Persian rug depicted an ancient forest. Beautifully done, it re-created a scene in Switzerland: mountains, a waterfalls, a turquoise lake, forested hillsides, and an expansive blue sky dotted with clouds. Anyone in that shop could have spent their time noting the details: the number of knots per square inch, the fabric of the carpet, the types of dye used—all the minutiae that resulted in the rug. Or the person could have focused, instead, on the arresting techniques and themes that gave the carpet its unique beauty: the sky reflected in the lake, the snow that capped the mountains, the verdant forest complemented by the deep green moss. The themes of the carpet combined with one another in a deftly coordinated display of beauty to manifest the splendor of that serene spot in the Alps. This quarter we will be studying another finely crafted masterpiece. This work is not the result of a brush on canvas, or a precisely framed photograph, or a skillfully woven carpet. Rather, it is the Word of God, as artfully expressed in the Gospel of John. Words have meaning within their contexts. For anyone to understand what Scripture intends to say, it must be studied in context—the immediate sentences, chapters, and sections, and the overall message of the Bible itself. Finally, because the entire Bible is inspired by the Holy Spirit, each part should be studied in the context of the whole.
