An oversized music box takes to the streets, packed in vintage furniture and cranked by passersby, in this Portuguese sound art piece.

It’s the latest work of friend-of-the-site Nuno Santos, who has gone viral in social media with this enchanting demo video. For more information, though, you can watch a detailed making-of series he’s produced. (Portuguese, but with original English subtitles – the behind-the-scenes bits follow just after the demo.)

There’s a lot of clever engineering work in this award-winning project. It’s an achievement in packing a sound system into a mobile form factor using vintage furniture. It’s a great physical computing project, complete with that huge crank. And it’s a great example of what you can do with pisound and Raspberry Pi – adding high-fidelity audio functionality to the ubiquitous, dirt-cheap tiny PC.

Adding that pisound bit:

And, of course, for mechanical engineering and some 3d printing, the crank!

Nuno shares a gallery of how this all comes together.

Imaginando are creating all sorts of good stuff, including my favorite Traktor iPad controller and one of my favorite Ableton controllers – plus a nice way to connect your Teenage Engineering OP-1 to Ableton Live.
