................great warriors of mother land............

.....................Real Time Heroes.................

Leaving the connection to my last post ....

Hero's a word whenever heard,describes a personality endorsed with every quality.Heroes are idols whom people follow in life.Actors,cricketers,sports personnel,politicians are some categories known to every one and every one must be following someone in any respect...

But have to ever thought of the heroes who die for there country and given only a medal in view of there sacrifice towards the country.....
Country must respect and honor there sacrifice....
There sacrifice must not go in vain.I only want to say that,people know about Sharukh khan,Sachin tendulkar,Yuvraj singh,Akshay kumar etc etc,but real time heroes must be remembered other wise who will sacrifice for the nation ....
MOST PEOPLE will be still confused that what i am talking about.Guys i am talking about the sacrifice done by the the defense personnel's...
Only giving a medal in lieu of the sacrifice in not what they sacrificed there life...
They must be remembered so that young generation must take right idols in life..
Stories about there courage must be published,lessons about there life from becoming plant to tree must be taught in schools.Families of those persons must be honored...posters of those brave guys must be there in market so that people can know about there 's ideology.....

I am not saying that, do some thing hifi for them ,but they must be remembered every year....
I am discussing all this becoz most people don't know the name of any param veer chakra vijeta the highest gallantry award given by Indian government...
I am shameful to say that in a few years even people will EVEN remember there name.They are mostly remembered whenever war is there....
Government can give crore of rupees to world cup winners,to actors,but is government is ashamed of giving some help to all those people who died for hind...who died for there motherland....
But this help will never come unless youth will take action .....but how youth will remember....as no where any topic of these guys are discussed...
There are real heroes in my eyes .i like actors ,sportsmen .But when ever i read about the gallantry shown by these people,I feel something which i cant explain from heart....

From Punjab to Assam ,from Jammu and Kashmir to Kanyakumari ,whole land had produced warriors who led there country to pride,who sacrificed there lives to save ours,who were in battlefields when everyone was sleeping,who were surrounded by enemies when every one of us was with our relatives.
There sacrifice in unforgettable.There are many who gave there life for this country and nation and people of this nation must respect them ...names of theses guys are only found on ssb centers or in defense academies.There stories must be published so that every children of this country must put his name before any actor,politician ,sportsman.They must remember there names with pride.Here are the few names but list in too long ..............

life is a race......

Presently sitting at this point of time....
Having nothing to do .....
Wasting time in chatting on yahoo,gmail ,g talk,face book...
realized to start again ...................
I wrote already on my word press.com.
Starting from the backdate memories.....

A One and Half YEAR Back

Sitting in hostel room,thinking about the final year which is going to finish soon.Friends will not met again.With recesion in markets and no companies coming in college,no placements every body was worried.At the end of 7 semester one company came ........

Some didint sit for it as package was low,but few like me,having no patience sat for it.Finally 5-6 were selected and we were in defaulters list.
And the party began in the evening.
Lying on the bed with lights swithed off,thinking of future and cursing god slept...
New day started.....
Got a news that cleared Navy interview.Thought,something is better than nothing,but was not confident as was rejected a few months back from Allahabad board.Argued with parents when they saw a call letter from the board,as they don't want me to join defense.
AND with all these time passed on .Semester exams came and after that holidays.
then started preparing for SSB interview.

remote control using dtmf

Radio Remote Control using DTMF

Theory/Working Principle- Here is a circuit of a remote control unit which makes use of the radio frequency signals to control various electrical appliances. This remote control unit has 4 channels which can be easily extended to 12. This circuit differs from similar circuits in view of its simplicity and a totally different concept of generating the control signals. Usually remote control circuits make use of infrared light to transmit control signals. Their use is thus limited to a very confined area and line-of-sight. However, this circuit makes use of radio frequency to transmit the control signals and hence it can be used for control from almost anywhere in the house. Here we make use of DTMF (dual-tone multi frequency) signals (used in telephones to dial the digits) as the control codes. The DTMF tones are used for frequency modulation of the carrier. At the receiver unit, these frequency modulated signals are intercepted to obtain DTMF tones at the speaker terminals. This DTMF signal is connected to a DTMF-to-BCD converter whose BCD output is used to switch-on and switch-off various electrical applicances (4 in this case). The remote control transmitter consists of DTMF generator and an FM transmitter circuit. For generating the DTMF frequencies, a dedicated IC UM91214B (which is used as a dialler IC in telephone instruments) is used here. This IC requires 3 volts for its operation. This is provided by a simple zener diode voltage regulator which converts 9 volts into 3 volts for use by this IC. For its time base, it requires a quartz crystal of 3.58 MHz which is easily available from electronic component shops. Pins 1 and 2 are used as chip select and DTMF mode select pins respectively. When the row and column pins (12 and 15) are shorted to each other, DTMF tones corresponding to digit 1 are output from its pin 7. Similarly, pins 13, 16 and 17 are additionally required to dial digits 2, 4 and 8. Rest of the pins of this IC may be left as they are. The output of IC1 is given to the input of this transmitter circuit which effectively frequency modulates the carrier and transmits it in the air. The carrier frequency is determined by coil L1 and trimmer capacitor VC1 (which may be adjusted for around 100MHz operation). An antenna of 10 to 15 cms (4 to 6 inches) length will be sufficient to provide adequate range. The antenna is also necessary because the transmitter unit has to be housed in a metallic cabinet to protect the frequency drift caused due to stray EM fields. Four key switches (DPST push-to-on spring loaded) are required to transmit the desired DTMF tones. The switches when pressed generate the specific tone pairs as well as provide power to the transmitter circuit simultaneously. This way when the transmitter unit is not in use it consumes no power at all and the battery lasts much longer. The receiver unit consists of an FM receiver (these days simple and inexpensive FM kits are readily available in the market which work exceptionally well), a DTMF-to-BCD converter and a flip-flop toggling latch section. The frequency modulated DTMF signals are received by the FM receiver and the output (DTMF tones) are fed to the dedicated IC KT3170 which is a DTMF-to-BCD converter. This IC when fed with the DTMF tones gives corresponding BCD output; for example, when digit 1 is pressed, the output is 0001 and when digit 4 is pressed the output is 0100. This IC also requires a 3.58MHz crystal for its operation. The tone input is connected to its pin 2 and the BCD outputs are taken from pins 11 to 14 respectively. These outputs are fed to 4 individual ‘D’ flip-flop latches which have been converted into toggle flip-flops built around two CD4013B ICs. Whenever a digit is pressed, the receiver decodes it and gives a clock pulse which is used to toggle the corresponding flip-flop to the alternate state. The flip-flop output is used to drive a relay which in turn can latch or unlatch any electrical appliance. We can upgrade the circuit to control as many as 12 channels since IC UM91214B can generates 12 DTMF tones. For this purpose some modification has to be done in receiver unit and also in between IC2 and toggle flip-flop section in the receiver. A 4-to-16 lines demultiplexer (IC 74154) has to be used and the number of toggle flip-flops have also to be increased to 12 from the existing 4

We can control various electrical appliances by remote control switch .
