Basic learning conspet for Mobile Jammer

Project on mobile jammer:

Before starting this project we must know some basic information.

1)what is Mobile jammer?

2)How it works?

3)Jamming techniques

4)Design parameters(or)specifications

5)Regulated power supply

6)How we generate large amount of frequency.

7)Basic information about oscillator

8)what are required things for developing mobile jammer

9)And also know where these jammers are most useful in our daily life

Brief introduction about regulated power suply

Regulated power supply(RPS) is use full for converting Ac power to Dc power.
Block diagram for  RPS:

It has 4 main steps to construct RPS:
 1)A Step down Transformer
 2)A Rectifier
 3)A Dc Filter
 4)A Regulation

1)A Step down Transformer:
                                       It will requires Ac power from the load.
2)A Rectifier:
                    It has mainly contain 4 diodes opposite to each other.It will convert full cycle to half cycle as like as in block diagram
3)A Dc Filter:
                    From rectifier will give high ripple content.But we need only pure ripple dc wave form that why we are going for filtering.It contains mainly capacitor and resistor
4)A Regulator:
                    Regulator is useful for constant dc power supply

so friend try to develop Regulated Power Supply in your lab..all the best friends..

Pre plane for TCS to get briliyant students for their company

HAI friends TCS(TATA CONSULTANCY SERVICES) will conducting a special online exams.If we participate those exam there are many uses further our future life if we select one of the top ranker in that exam we will directly enter into interview round not at all written test and hr round.And top three ranker will get a prize money and also a job in that company.Codevita and techmony are mainly conducting TCS.Engineering 1st year and 2nd year students are eligible for this exam.So friends be cool,write well,get experience and also win some valuable prizes and if you interested  TCS will give job after completion of your engineering.

How to start gate preparation

Nowadays all students are very much interested for their higher studies...
    Gate is best one for engineers.In our B.tech life starting 2 years are very very important why because lot of syllabus covered this 2 years.3/4 of our B.tech syllabus will covered starting 2 year that why we must focus those subjects and the fact is max syllabus from gate question paper having this 2 years syllabus.we are thinking gate questions are easy.It is only true when we have that much of knowledge and they are giving our basic subjects with different way.Why because they are testing how the student mind set,how he(or)she solve the problems and how he(or)she know basics regarding their branch.In gate aptitude also plays a main role so better to prepare those topics

Flexible energy storage is smaller, cheaper, better

Flexible energy stirage is smaller,cheaper,better and more use full...........

summary:

Engineers have developed a way to make a magnetic material that could lead to lighter and smaller,cheaper and better performing high frequency transformers,needed for more flexible energy storage systems and
widespread adoption of renewable energy.
