-<meta property="og:description" content="After building the first version of this music player for my oldest son in 2016, I recently had to update my project for his younger brother. As before, music can be played by simply placing a card with a QR code on the player. The new version has an improved case and is cheaper and easier to build. Internally it uses the volumio player which allows to not only play all MP3s from the local network, but also to connect streaming services like Spotify. Oh, and there is a rocket again, too. But this time it is optional." />

Since the creation of the cards can be a bit of a hassle when the collection grows larger, I have written a card generator for Spotify links. It takes a list of Spotify URIs as input and generates a PDF with the QR codes, the title and the album art. The information is printed both on the front and the back of the cards in order to make sorting of card stacks easier. I will put the generator online as soon as possible.
