AUTOMATIC METER READING SYSTEM

INTRODUCTION
This is a device to control the speed of fan and coolers automatically. The device presented here makes the fan run at a full speed for pre determined time. This speed is decreased to medium after some time and to slow then onwards after a period of 8 hours, the fan or cooler is switched off.

The circuit consist of IC1 (555 Timer IC) which is used as an astable multi vibrator used to generate clock pulses. These are fed to decade dividers or counters formed by IC2 an ....etc

INFRARED HEADPHONE

ABSTRACT

The circuit for INFRARED HEADPHONE is designed to demonstrate the transmission and reception of audio signal through ! infrared radiations. The infrared rays generated by the transmitter circuit are received by the receiver circuit after transmission through air. This communication is much more effective than ordinary communication. It helps to receive audio signals from any audio device like T.V,radio etc.
i
without disturbing others. It provides minimum transmission loss. It is a low ....etc

Chapter I
INTRODUCTION
i.Background
The path of exploring the final year project had many barriers, but it made us imbibe some valuable knowledge of the field. We started searching project from internet and various magazines. We saw a number of projects from EFY and CHIP Magazine. We came across many projects on DC motor control, tachometer and RPM meters; but all these projects seemed to be very common, so using this concept we thought to have the idea of counting the RPM of any motor and we discussed this topic with our ....etc

ABSTRACT
The recent growth of power circuit capacities has caused fault currents to increase. Since the protection of power systems from the fault currents is very important, it is needed to develop a fault current limiter. A fault current limiter is required to assure (1) rapid reaction to fault currents, (2) how impedance in normal operation and (3) large impedance during fault conditions. A super conducting fault current limiter (SCFCL) can meet these requirem ....etc

ABSTRACT

Stepper motor rotate by applying sequence of pulses to the stepper Motor coils. Speed of the motor is based on the sequence of pulses to the motor. Direction can be change by changing the pulse sequence inversely. Here in this project pulse is getting from PIC Microcontroller. It’s a Programmable Peripheral Interface controller. Here keypad, Stepper motor Driver both are interfaced with the PIC Microcontroller. Keypad is used to vary the speed and to change the direction Of the stepper motor.

Controller output is given i ....etc

LASER TORCH BASED VOICE TRANSMITTER AND RECEIVER
Using this circuit you can communicate with your neighbors wirelessly. Instead of RF signals, light from a laser torch is used as the carrier in the circuit. The laser torch can transmit light up to a distance of about 500 meters. The phototransistor of the receiver must be accurately oriented towards the laser beam from the torch. If there is any obstruction in the path of the laser beam, no sound will be heard from the receiver. The transmitter circuit (Fig. 1) comprises c ....etc

ABSTRACT
A power supply system using a transcutaneous transformer to power an artificial heart through intact skin has been designed. In order to realize both high-voltage gain and minimum circulating current, compensation of leakage inductances on both sides of a transcutaneous transformer is proposed. A frequency region which realizes the robustness against coupling coefficient and load variation is identified. In this region, the converter has inherent advantages such as zerovoltage switching (ZVS) or zero ....etc
