    ic query

    is there any ic which can give me a constant level of voltage even two volts or in other words is ther any ic which give a regulated DC voltage of 2 or 1.7 volts volts for the varrying 1.23 to 1.5 volts.

    rf coil

    thanks to all of the contributers to my project. me got A++ grade in the project. but i wold strongly recomend that before doing anything just read the monostable operation of the 7555 ic. all the questions wold be solved bc how this circuit works and how the 7555 and the inciming signals works...

    rf coil

    hi respected contirbuters. i got the circuit working today, but not because of the coil that is mentioned in the circuit but rather i took a rf coil from the market of about 10mH same as that is found in our radios. so mak it clear that u use the same as that is used in our radios of about 10mH...

    rf coil

    in the ciruit suggested to me by someone here;in that circuit the 7555 has one pin empty. i grounded that pin and now the result is that there is a but high chnge in amplitude across the inductor but that is only about few millivolts and they are not being amplified by the transistor, so tel me...
