This is such a cool idea! It’s a custom bracelet of a soundwave rendered in 3D. The bracelet is “designed” by the waveform of the message it encodes.

The bracelets were originally part of the Sound Advice Project, a teen anti-drug abuse initiative, geared at getting parents to talk to their kids. The idea is that, as a parent, you record some message to your child (“Drugs are bad, m’kay?”) and he or she carries that message with them at all times. Not sure that giving a 3D model of a soundwave is really the most direct way of talking to your kids about drugs, but it sure gets points for creativity and conceptual chutzpah.


After this project was completed, the original designer, David Bizer, began offering the bracelets on his website. He also has put up an Instructable on how to make this kind of waveform jewelry yourself.

    It does say on the second part where it says “find your words” that you can choose anything to say to record for a bracelet even if it isn’t drug related.



    Good for a remake… 10min with Pd and ponoko = done.

      I hope you continue making these and other great unique pieces of art…. I was truly inspired to see all that you have made!

    • Cattnipp

      I think it’s absolutely wonderful that while you still produce them for people who want them you also offer a way where people can make them for themselves and have pretty exactly the same product. I don’t see many people doing that these days and I feel it just proves that you do this because you love it and the money isn’t what your focus is :3 keep on being awesome <3

    You can find these on Etsy. Just type in Soundwave Bracelet. They don’t look like these, but they use the same concept.

    One would think that anyone whose age is expressible in two digits could write a proper English sentence …
