1 Jack plug Male Stereo

1 Switch

    do this circuit works for a stereo system , like i designed a system in which 3.5mm stereo jack is used and i use to connect it to computer to listen song through speaker do this mic work with it if i talk in that would i be abble to transmitt my voice through this designed stereo mic.

    This mic work verywell for PC but remember is for soundscapes records, i mean, is for record sound ambients.

    i cant understand the circuit well, hmm why is that there is only 1 electret mic on the schematic? help here total noob and i want to make your project badly!

    Hi, because is the circuit for 1 channel, if you need 2 channels (Left and Right) just make twice and put in the same box, with same battery and switch but 2 mics of course.

    I'm confused, is this an amp or a sound recorder?

    Hi, the project is a mic amp for use in Minidisc with Line in for field recording

    Awesome! Very easy, kind of, nicely done, very cool. I might try this out if possible. +5/5 stars.

    Thanks for stars and words, if you make your own, please let me know and share photos!!

    to make it more "beatifyl" u could use a pc board just a thought

    maybe, but the Ugly style is a great design!!! :-)
