DC MOTOR SPEED CONTROL USING 555 TIMER IC
$40.87$28.85This project is designed to control the speed of a DC motor using PWM control using 555 IC. The speed of the DC motor is directly proportional to the voltage applied across its terminals. Hence, if the voltage across the motor terminal is varied, then the speed can also be varied.

DEVELOPING AN ISLANDING ARRANGEMENT FOR GRID ON SENSING BAD VOLTAGE/ BAD FREQUENCY
$93.76$76.93The project is designed to develop an islanding arrangement for grid on sensing bad voltage/ bad frequency. There are several power generation units connected to the grid such as hydro, thermal, solar, wind etc. to supply power to the load. In modern power system, electrical energy from the generating station is delivered to the ultimate consumers through a huge network of transmission and distribution. These generating units need to supply power according to the rules of the grid. Thus, for satisfactory operation of loads, it is desirable that consumers are supplied with substantially constant voltage and frequency.

Diesal Generator Body Leakage Current Measurment And Auto Switching Based On Leakage Current
$114.19$100.97The emergency diesel generators in a nuclear power plant have an important safety function-supplying emergency electrical power to maintain cooling and other vital functions. The research reviewed in this article addresses the safety implications of aging of these emergency diesel generators and the influence of aging on their reliability. Historical operational information was assembled on component and system failures and their causes. One significant research result is that the fast-starting and fast-loading test procedure mandated by Regulatory Guide 1.108 and the standard Technical Specifications has contributed to wear and degradation. Other equally important aging and degradation factors for the diesel generators are identified and reviewed. A new approach developed represents a more balanced aging management program that includes (1) slow-start testing during which operating parameters are monitored.
(2) Analysis of data trends,
(3) Training.
(4) Maintenance.
This approach should improve safety by identifying aging degradation that leads to fitture diesel generator failures. Timely maintenance could then prev*ent actualJafiures.

DISH POSITIONING CONTROL BY ANDROID PHONE
$96.16$62.50The project is designed to develop a dish positioning system which can be operated by using a conventional android phone. The main application of using a dish is to receive signal from satellites and other broadcasting sources. In order to position the dish to the exact angle to receive the maximum signal of a particular frequency, it needs to be adjusted manually

Driver Safety System Using Sensors Like Eye Blink, Alcohol, Temperature, Smoke, Accident Prevention, Using Arduino
$114.19$106.98This aims to create a framework to keep the car safe and secure through critical activity. When we run in ignorance we cannot take care of our own. If we make all vehicles with an automatic safety system that gives the driver a high level of protection, an alarm will also be issued. The device has an installed eye blink sensor. Once the driver has started the engine, the sensors automatically detect the blink of an eye. On this device, the output of the sensor is provided for comparison with ARDUINO. When the value reaches the set level, the buzzer automatically vibrates, the LED glows, and the car stops automatically when the eye blink sensor receives a signal from the transmission module.
Nowadays There has been a very large increase in road accidents due to the drowsiness of drivers while driving which leads to enormous fatal accidents. The driver loses control when he falls asleep which leads to an accident. This is because when the driver is not able to control his vehicle at a very high speed on the road. Driver in-alertness is an important cause of most accidents related to vehicle crashes. Driver fatigue resulting from sleep deprivation or sleep disorders is an important factor in the increasing number of accidents on today’s roads. A drowsy driver warning system can form the basis of the system to possibly reduce the accidents related to driver drowsiness. This project can generate a model which can prevent such accidents. To prevent this, we outlined a very simple and economical system that deals with this issue. In this project, when a driver falls asleep, an alarm is raised to warn the driver attached to the rear of the vehicle. The alarm continues for a minimum of 10 seconds so that the driver wakes and gets ready to steady the vehicle he drives. Thus we can control major accidents.

EARTHQUAKE DETECTION & IT’S MONITORING OVER IOT
$129.82$108.18In this processed system, we are monitoring the earthquake, if any vibration/ tilt of the earth’s surface takes place; the system will alert us and send the data over IOT page. So to avoid the life loss and economic loss we are developing this device.
In this project we are using Arduino board i.e. the heart of project, 2-vibrator sensor, 2-accelerometer, LCD display. An accelerometer is an electromechanical device used to measure acceleration forces and also for sensing vibrations in systems or for orientation applications. So when some orientation according to x-axis, y-axis or z-axis happens to the earth’s surface then it will display a message on LCD that there is Earthquake. And also sends data on IOT page through Wi-Fi module.
