Electronic vuvuzela

Want to annoy fellow fans but  don’t have the lung power to do the job? [Hunter's] electronic vuvuzela is just the thing you need. The plastic noisemakers were so prevalent at the world cup this year that some folks came up with audio filters to remove the sound. The electronic rendition is much smaller, using a 555 timer to mimic the instrument on a small speaker. [Hunter's] build has buttons for five different notes which can be altered with some potentiometer. There’s no schematic but then again for something that’s annoying you don’t want to make it too easy to replicate.

Update: Hunter added the schematic to his site which spell doom for those who enjoy peace and quiet.

    I always like things made by young people.

  3. Anon says:

    Kill it! Kill it with fire!

    Giant Vuvuzela in Cape Town. It’s controlled via SMS.

    oh god no!!!! the horror!!!!

  7. no. says:

    Did he actually say trolling? So much potential….

  8. Hunter says:

    Schematic added to my site. oh and it sounds beautiful over two 12″s.

  9. chango says:

    What value is the output cap? It seems like that’s the key to getting the right sound.

    @no. I offer up the term “livetroll”.

  10. Hunter says:

    It is a 10 uF cap

  11. chango says:

    @Hunter Well done. It reminds me of making noises in BASIC on my Apple //e.

    You should stick the speaker at the end of a long cardboard tube for added annoyance.

    You’re fcking kidding me.

  13. Do you know the difference between a Vuvuzela and your wife?

    One of them makes a whining sound and the other is a plastic horn.

  14. Patrick says:

    Is that Michael Cera narrating?

  15. l0l says:


    Reminds me of this, a fun little device.

  16. Mikey says:

    Wow, this kid knows way more about electronics than I did when I was 12.

    Terrorizing McDonalds LMFAO, that’s amazing.

  17. Fallen says:

    Because subwoofers are great at reproducing 1.2kHz…or whatever vuvuzelas fundamental is.

  18. zool says:

    yeah basically just the 555 toy organ, not really a hack although 555s r fun

  19. derp says:

    was hoping for a closer matching of sound but vuvuzela jokes always make me smile for some reason.

    yay for young people + electronics :D

  20. Osgeld says:

    you never outgrow the 555, once bread boarded a VGA sync signal out of a 556 dual timer and some fidgety resistance adjustment

  21. Osgeld says:

    ps: that was not in 87 I just havent replaced my clock battery in the scope lol

  22. Hunter says:

    @sodor nah but I did make a laser spirograph Ill upload a vid today on my youtube page

  23. jk says:

    “So we can go terrorize McDonalds” LMFAO

  24. HB says:

    Small difference: Vuvuzela are much louder -some versions up to 140db-

  25. Jack says:

    Pretty simple build, did similar thing in H.S in electronics class, although we weren’t going for the vevuzela sound…

  26. walt says:

    “bascially… aaa… aaa… basically… aaa…”
    I hate to be the negative guy who starts this, but what was hacked here?

  27. Jake says:

    Hahaha, I remember building something like this from a “Heathkit” magazine or something, back in the 80’s. I must have been about 8, my parents got so annoyed with it that they took it away and I never got it back :'(

    It’s not a hack, but it’s a fun project for a beginner. Kids everywhere could disrupt their parents peace and quiet with this weapon of audible destruction…
