    circuit simulator

    hi audioguru! not even a single one in my case too.but there is a certain fact that i have noticed and hope u would also have.over prolonged use of same device in circuits,the device parameters (most troubling for me was Hfe) change and degrade the device performance. so arises the need to test...

    EYE SIGHT SENSOR

    HI THERE! YOU MEAN TO SAY A PROJECT WHICH CAN BE CALLED A COLOUR DETECTOR? WHICH TELLS ME THE COLOR OF THE OBJECT IT SEES? PRATEEK :)

    Night Vision Camera

    hi there! BUT I DONT UNDERSTAND WHAT IS THE FUN OF USING IR RADIATIONS WHEN U CANT SEE THEM ESPECIALLY IN A DEVICE AS NIGHT VISION CAMERA.A SIMPLE FLASH WILL DO THE JOB. :) PRATEEK

    EYE SIGHT SENSOR

    hi there! any other project related to light with anybody if the eyesight sensor is not possible? ??? prateek

    Night Vision Camera

    hi there! is it the infrared or night vision camera? for night vision camera,u need to incorporate a flash generating mechanism in it. prateek

    Create circuit for 4-20mA simulation

    hi there! are u interested in telemetric sensing? your limits of current show it. what type of circuit is the one u wish to simulate? which current limits are 4-20mA? ??? prateek

    Capicitor Help

    hi there! you must also check for the surges in the supply current for the capacitor. Varying currents produce the magnetic field and thus electromagnetic waves produce the sound. this could solve the problem.dont forget 90% of electronic bugs are in the power supplies. :) prateek

    Changing backlight in LCD display...

    hi nazx! you cant change it through your software and i do think that u cant even remove the back panel light but u can add a few leds more which are configured by your software by hardware u would have to change the source inside.Dont mess up until it is very necessary :) prateek

    Good Books?

    hi tekker! books are many in number but there lies the task of gaining knowledge.go through my punch line (personalized text) in this forum . No limits! ;D prateek

    RC time constant

    hey! what is the constant of integration for an integrator?just like we have Sin(x)+C as integral of Cos(x)? prateek

    DIGITAL STOPWATCH(Chronometer)

    hi there! it would be much easier for you to debug and compile the software which u write in C or C++ than in 8086 or 8085 assembly language. prateek :)

    TRANSISTOR ATTENUATOR?

    OFCOURSE BUDDY! WE HAVE TRANSFORMERS TOO AND L-C-R CIRCUITS TOO,BUT ONLY THE INSTANTANEOUS VOLTAGE CAN EXCEED THE SUPPLY NOT THE RMS OR AVERAGE OTHERWISE ALL POWER PLANTS ARE USELESS! ;D PRATEEK

    Good Books?

    the book title is "PULSE AND SWITCHING WAVEFORMS" BY JACOB MILLMAN & TAUB OTHER GOOD BOOKS ARE "SHOENBECK ", "SIMON HAYKINS" "OPPENHEIM WILLISKY" CHECK OUT THE SPELLINGS AGAIN BUDDY 8) PRATEEK

    TRANSISTOR ATTENUATOR?

    hi there! can we even then conclude that even if it has a high gain,the o/p can never exceed the fixed supply.I may even generalize that voltage at any point in a circuit can never exceed the supply! :) prateek

    TRANSISTOR ATTENUATOR?

    hi audioguru! even if there is infinite resistance between the 2 pins even then the signal will exist between the 2 pts equal to the applied signal say 5mV.how can i/p signal be considered as 0 even if it is present? prateek ::)

    RC time constant

    yes audioguru! and that too low pass and high pass filters used in respect of signals are nothing but differentiators and integrators. :) prateek

    TRANSISTOR ATTENUATOR?

    HI AUDIOGURU! FOR OPAMP TOO ! THAT HELL OPAMP! COULD YOU PLEASE TELL ME WHAT IS THIS VIRTUAL GROUND?WHY DO WE ASSUME IT? I AM CONFUSED WITH AUTHORS WRITING V1=V2 AT 2 PINS OF THE OPAMP. AND ONE IS AT VIRTUAL GROUNG SO V2=0,HENCE V1=V2=0. HOW IS THIS? ???PRATEEK

    EYE SIGHT SENSOR

    HI MP! THE LINK GIVEN BY YOU GIVES THE SPECTRUM OF WHITE LIGHT ,THE WAVELENGTH AND FREQUENCIES.BUT I WISH TO KNOW WHAT THING WOULD YOU EXPLOIT FROM THE HUMAN EYE TO GET THE OUTPUT? LIKE IF I RADIATE LIGHT AND RECIEVE IT BACK,HOW TO JUDGE THAT IT HAS REFLECTED FROM THE RETINA AND NOT MY GLASS...

    Good Books?

    hi there! tekker! i know a book for basics which you cant live without even if u know noting of electronics and even if u know everything about electronics.the book is called "ELECTRONIC PRINCIPLES" by "MALVINO". IF U HAVE READ FUNDAMENTALS OF PHYSICS BY RESNICK AND HALLIDAY PREVIOUSLY THEN ITS...
