Arduino Bluetooth Audio Boombox: Details and parts

Finally done, not painted but it is all together and working. It looks a little sketchy but I am quite happy with it. If you would like to know anything not covered in the video please let me know in the comments and I will endeavour to reply.

Let me know what you think.

    I like to build things and I’m just getting into electronics. I purchased an arduino and a few other components. I would like to build the FM receiver with the TEA5767 and an amplifier with the Nokia display. (specifically to put in the housing of my vintage car AM radio). I am not good with code and don’t really have an interest in the programming part of this build. I would be willing to purchase the partial code for the parts I spoke of, if you would be willing to sell it or share it with me.
    Thanks, Jim Tyson (Tallahassee, Florida 32312)

    Great Project. One question, how did you wire the bluetooth 3.5mm to output audio to the speakers? I understand how to wire to get power.

      Hi Stephen,

      I used a 3.5mm jack lead from the bluetooth module and broke out the wires to solder them to my amplifier input.

    Could you please provide me with the circuit diagram in order to make Arduino Bluetooth Audio Boombox by myself.

      I am afraid that I don’t have a schematic for the boom box, I never really created one. If you are having trouble I would be happy to advise.

    Congratulations! I saw you on the Adafruit Show&Tell. I think you said it was your first attempt at this kind of project. You should be very proud, the boombox turned out nice.

    I paid attention to the S&T because I’m also in the midst of a boombox build. Was thinking of the MSGEQ7, I have played with it before on a VFD. Your use of the MSGEQ7 has convinced me I should put it into my project.

    Here’s wishing amazing projects for you,

      Cool, thank Bob.

      It was my first big project, big for me at least, and it turned out OK…

      The MSGEQ7 is cool and take the hassle out of analysing the frequency on low powered boards like the UNO. A Teensy could whip though the FFT but I did have one at the time, I also needed more pins and current. I will keep an eye on your blog for updates on your Boombox, you should post them on Google+ too, there are some great communities on there (Make and Arduino).

        Hi David –

        I finally built my version of a Rpi boombox. Here’s a link to my blog post:

        I wanted to make sure I mentioned you in the post as a source of inspiration!

        I showed the boombox on Adafruit. Show & Tell 06/18/2014. I also showed a mini version on Show&Tell 05/28/2014.

          Thanks Mate, very kind of you.

          I watched you on the show and tell for your mini version in the coffee tin. I missed the next one, I will check it out.

          It looks amazing, I kinda hate you, it is so superior to mine in every way. Well done, it look seriously cool.
