    FM modulator light only and no transmitting

    well I would like to track down an alternative starter project

    FM modulator light only and no transmitting

    I see so do you think I can use crystal locked oscillator in the circuit in post #74

    FM modulator light only and no transmitting

    thank a lot KrisBlueNZ what do you mean with unstable frequency in the video it use trimmer capacitor to control the frequency..do you mean that the frequency will keep changing?? what is the Phase Locked Loop? what its use how about this video it use mp3 player to transmit it..dos it have...

    FM modulator light only and no transmitting

    I agree with you but this is not for saving money it's for me to learn and what I mean about build power supply I meant for the FM transmitting like the one you draw for me that one I'll build but Kris said that we can put diode to make it better and I'm nope I'm trying to learn of you guys...

    FM modulator light only and no transmitting

    will for now I'm going to build my own FM transmitting so i'll start from zero thus I wonder if you can help me to build a good power supply circuit for the transmitting and a good FM transmitting circuit that work on line in

    because of that kris said

    FM modulator light only and no transmitting

    Gryd3 I wonder if you can help me with a draw for the power circuit on Verboard I been waiting for the draw to start building it

    FM modulator light only and no transmitting

    ok I hope you can help me build good mono FM transmitting that have line in, I think I'll run it on my mp3 player so the transmitting will take power from the cigar lighter and have audio from line in

    FM modulator light only and no transmitting

    what is the difference between mono and stereo? what will be the effect?

    FM modulator light only and no transmitting

    how about something like that or this I guess in the second video I can replace the mic with audio in as in the first video but I wonder if I can do flash driver reader or that what is going to require programming

    FM modulator light only and no transmitting

    that thing beside the black blob what is that item it's round and tall.. I wonder if you can help me build FM transmitting board that read from flash drive and transmit it

    FM modulator light only and no transmitting

    hmmm so what could be the problem is it the IC or what by the way what is that silver thing that look like capacitor

    FM modulator light only and no transmitting

    ok I tried it gave me 5 v so I gather it all and tested it and the same problem it gave me light only so I think the issue were not the power

    FM modulator light only and no transmitting

    can you show me on board the points where to connect the wires?
  15. pharaon

    FM modulator light only and no transmitting

    I know.. I mean we can design another board like the one I show in the latest pic I believe they all provide 5 v with antenna as well

    FM modulator light only and no transmitting

    can't we make the power circuit with different items that I can find locally some thing like this or like this

    FM modulator light only and no transmitting

    i have tested it and its 0.74 I think I can take the diode from the old board so hope some one can supply me with draw for the new board

    FM modulator light only and no transmitting

    I got f36ph zener diode they told me it's 5.6 v but how can I check
  19. pharaon

    FM modulator light only and no transmitting

    how can I measure the diode volt to know if its 5.6 or not
  20. pharaon

    FM modulator light only and no transmitting

    is there any other diode can work rather than 1N5232B in case I couldn't find 1N5232B
