Touch your digital music collection

Here’s a quick demo I made to experiment with a physical interface to control a digital media system. I sometimes miss having a whole load of CDs or records to flip through – partially because of the feel of it, and also because I recognise and remember some music by the picture on the cover.

Here we use a Raspberry Pi computer with a web cam to read QR codes printed on the back of 7″ album covers. When I hold up a QR code, the album starts playing.

  • The camera works from about 2 meters away but this can probably be improved.
  • I asked a local printer and they reckoned printing 150 album covers on quality card would be about £75.

If you want to make it better, check out the source and get involved!
