 <meta property="og:description" content="In spring 2016 I finalized the &quot;Musikrakete&quot;, an MP3 player that our boys could operate without assistance. This is the improved second version, which is even easier to use. Music is played by simply placing a QR code card on top of the sphere. It plays MP3 files from the local network or Google drive and audiostreams from the Internet. If you have children who love music, ever used a terminal and also know what end of a soldering iron not to touch, this might be a project for you." />
