    Fm Transmitter help plz

    ive seen a few postings for a 4 watt fm transmitter but the schematic is calling for a 12-16 volt supply. for class i have to design a narrowband fm transmitter and am trying to get about the same amount of power out or at least a 2 watt. restrictions are i must use a 9volt battery, + and - 3khz...

    Sine wave inverter

    taking a transistor in a bridge amplifier and tapping at the collector would produce a phase shift is that what ur looking for?

    Digital Tachometer?

    just use a frequency counter chip such as a ICM7224 or its led driving counterpart

    regulated 12 v dc and 500 mA current o/p

    you can stack 7812 or lm317 for more current. there are regulated powers supplies on this site showing this that could produce up to 4A if necesary

    Frequency Counter

    2n3904s are nice but somewhat expensive compared to various others. just get datasheets most of the replacements you can find at your local radioshack.

    reading these replies i dont see how some people can be called electronic gods. yes a camera could work to produce a desired pulse but the power would be so minimal you probably wouldnt affect anything. youd have to amplify the power alot more than what comes out of that little thing. in the...

    IC based FM receiver / Transistor

    dont have any schematics right off hand on this computer since im not at home but if you like using chips then a NE565 which is a pll chip can also be configured to be used as ur demodulator. might cut down on a few parts. just do a google search its not that hard to find examples of such...
