Super Simple FM Transmitter is the latest addition to our Weekend Projects series of beginner-friendly electronics builds. Whether you’re a beginner looking for a serious challenge or an advanced builder looking to put your soldering skills to the test, or you want to learn the unique “Manhattan style” of circuit-making, this project is for you!

FM transmitters can be complicated to build, but not this one — it’s about the easiest you can possibly make. And though the science of radio is well understood, there’s a magical, emotional quality about it that we don’t often stop to appreciate. Building your own radio receiver — or better yet, transmitter — makes it real again. You will not forget the first time you pick up a transmission broadcast from a device you soldered together, yourself, from a few bits of copper, carbon, plastic, and wire.

Inspired by Japanese multimedia artist Tetsuo Kogawa and modified from a kit, MAKE Technical Editor Sean Michael Ragan walks us through building this circuit in the video below. If you customize this circuit in your own way, or build it into an enclosure or otherwise, be sure to document your process and send us images and a story of your experience when you’re done. We love seeing what makers are up to with our Weekend Projects!

    Hey! Have you tested it? How good is the audio quality? How do you add another antenna? Thanks!

  2. AJ says:

    And does it not matter what type of NPN transistor you use?

    1. Nick Normal says:

      Indeed we employ the 2N3904 from RadioShack, and yes we built it no fewer than three times and it works great!

      1. AJ says:

        3904 ok thank you!

  3. AJ says:

    Can I replace the 27k resistor with a 20k,6.8k, and 2k resisters all soldered in series?
    Normally I wouldn’t ask this but this is a radio project. I don’t have any 27k resistors.

    1. Nick Normal says:

      Soldering resistors in series will create the correct (27k) value; however did you mean 200Ω instead of 2k?

  4. Riat says:

    Will I be able to receive stereo signal even though source of the signal is mono?

  5. AJ says:

    I’ve made this circuit 3 times in a row and none of them worked. I did everything according to the instructions. Any troubleshooting?

  6. skhan says:

    I built the thing on regular breadboard. Works great…will add the antenna. Playing with coil does give better results in some cases.
