    great price. thanks

    These work with raspberry pi?

      How would you use a raspberry pi and a radio transmitter together?

      • fantombloo on 26/07/2021 - 14:12

        You could transmit a tune made of simple square-waves to radio, or something more complicated with a DAC output. Pretty pointless for sure but could be great learning experience.

        • FireRunner on 26/07/2021 - 14:16

          True, I suspect it wouldn't be too hard if one wanted to do that.
          Solder in wires that can be connected to pi/DAC instead of the mic

          Edit: You could also solder a 3.5mm jack in place of the mic

          • fantombloo on 26/07/2021 - 14:22

            @FireRunner: Maybe a more challenging task is transmitting something deterministic to a radio with only the Pi and a wire connected to an output as an antenna!!!??

          • FireRunner on 26/07/2021 - 14:35

            @FireRunner: Had a better looked at the pictures, turns out it already has a 3.5mm jack lol

      • xoom on 26/07/2021 - 14:17

        connect the wireless radio to the raspberry pi. then have the raspberry pi connected to speakers and wifi.

        have other wifi connected raspberry pi with speaker and now sound from the radio can be wirelessly transmitted to the other raspberry pis.

        perhaps using the radio transmitter with a microphone and speakers.

        just up to your imagination what you can do with these along with raspberry pi.

        • FireRunner on 26/07/2021 - 14:24

          It's a transmitter not a receiver. I guess you could broadcast something other than just your voice through that tiny mic

          • xoom on 26/07/2021 - 14:25

            @FireRunner: im sure theres parts you can buy to make it happen.

            • FireRunner on 26/07/2021 - 14:30

              @xoom: A receiver is more complicated than a transmitter. You'll need a different kit or design and build from scratch

              • xoom on 26/07/2021 - 14:36

                @FireRunner: all the more fun and challenging right? thats the deal with these build it yourself kits.

                • FireRunner on 26/07/2021 - 15:02

                  @xoom: I don't think you modify this kit to become a receiver. You definitely couldn't use the PCB.
                  You're better off buying a breadboard and a bunch of components then designing and building from scratch

                    @FireRunner: For a receiver, something Si4703 based should work with the PI's GPIO. Cheap and both use 3.3V logic, so can wire straight up.

      • rhangman on 26/07/2021 - 14:57

        There are FM transmitter IC's that can be controlled digitally, so you could set the frequency via a Pi's GPIO, as well as display it. This uses an analogue inductor for tuning though, so not going to work.

      Yes, but none of them have band 28.

  • prattu on 26/07/2021 - 13:56

    this is so cool

    The first 2 remind me of IMO the best 2 kits in the old Dick Smith's Funway into Electronics 2. Simpler times, simpler circuits too.

    • Radiskull on 26/07/2021 - 15:45

      I had one of those AM kits from Dick Smith as a kid! We didn't have any kind of pliers and didn't cut the excess prongs off of any of the components so the circuit board had so many legs. It wasn't surprising that it was shorted soon after powering it lol

  • Sprintz25 on 26/07/2021 - 14:27

    Thanks OP, have ordered some kits to build with the kids during lockdown :-(

      Why :-(
      Should be :-)

      • Sprintz25 on 26/07/2021 - 15:51

        Yeah, i'm looking forward to building the kits with the kids, just not looking forward to more lockdown :-)

        • Unacceptable on 26/07/2021 - 17:20

          Nonetheless.
          Should be :-) 👍

    Just an FYI, that stereo FM transmitter is NOT stereo, it takes a stereo input and transmits it as mono so it is in fact a MONO transmitter.
