AUTOMATIC SPEED CONTROLLER FOR FANS WITH ON/OFF CONTROL BY LIGHT

ABSTRACT
The circuit designed here lets us turn ON/OFF a fan or any device by just directing a torch light or any other light towards its light-dependent resistor. In short we are tiying to develop a remote control for turning ON/OFF an electronic device.
During summer nights, the temperature is initially quite high. As time passes, the temperature starts dropping. Also, after a person falls asleep, the metabolic rate of one's body decreases. Thus, init ....etc

Design of Voltage Regulator
A transformer is a device with two or more stationary electrical ckt that are conductively disjointed but magnetically coupled by a common time-varying magnetic Field. Transformer are basically passive device for transforming voltage and current one of the windings, generally termed as secondary winding, transformer energy through the principal of mutual induction and drivers power to the wad. The voltage level at primary and secondary windings are usually different and any increase or decreas ....etc

Introduction
Preface To SWARAJ
Punjab, the bread basket of India, the land with 50376 sq. Km is situated in Northern part of India. It is agriculturally Indiaâ„¢s most advanced and most prosperous state. Punjab Tractors limited was promoted by PSIDC as one of its projects in 1970 for the manufacturing of agricultural tractors. Since, this gave independence to country from import of tractors, so brand name SWARAJ, total independence was given.

SWARAJ tractors conceived in 1965 by a team of dedicated engineers a ....etc

INTRODUCTION:
SMPS i.e. Switch Mode Power Supply, before starting to introduce this topic we first have to
know what power supplies are
Power Supply: A device for the conversion of available power of one set of characteristics to
another set of characteristics to meet specified requirements.
Conventional series regulated linear supplies maintain a constant voltage by dissipating excess
power in ohmic ....etc

Transformers
What is a Transformer?
• A Transformer is a device that is used to transfer electrical energy from one circuit to another through electromagnetic induction.
• Typically transformers are used to step up or down voltage between two circuits (though there are other uses).
• Electromagnetic Induction
• When a conductor passes through, or is passed by, a magnetic field, a current is produced in the conductor.
How Transformers Work
• Alternating current is passed through the primar ....etc

METAL DETECTOR

ABSTRACT
In security aspects, metal detector isan essential equipment. But, the metal detector, which is available in the market today, is very costly. Hence this stands as a problem for hobbyists and for small applications. Hence we have taken an endeavor to bring out a metal detector of minimum cost.

* Use of air gap magnetic flux probes-proven effective in detection of generator winding shorted turns
* Improve quality of predictive maintenance decision when or if to perform rework
* Can pinpoint the no: & location(pole & coil) of shorted turns without having to take generator offline
EFFECTS OF SHORTED TURNS IN ROTOR WINDINGS
* If percentage of total turns shorted out is small, the generator may be able to run at rated load for years without further proble ....etc

ABSTRACT
Necessity is the mother of invention. Energy crisis is the cry of
future.
The historical and the present-day civilization are closely interwoven
with energy and in future, our existence will be more dependent upon
energy. The conventional sources of energy, the single most important
pre-requisite for power generation, are depleting fast. The world is
heading towards a global energy crisis mostly due to running out of
these energy sources; decreasing the dependency on fossil fuels is
recommen ....etc
