Here’s a fun little hack. It combines the convenience of digital music with the tactile pleasure of browsing through someone’s music collection and having something physical to pick up and look at. Flickr fella bertrandom put it together in his spare time.
Each plastic disk represents an album or a playlist. Inside each one there’s a RFID tag. To play it, put the disk on the cardboard box turntable, in which there’s an RFID reader connected to a computer. The music starts immediately.
Of course, you might argue that if you’re going to have a shelfload of plastic disks, you may as well just have a shelfload of CDs, which is perfectly retro enough for some people. But where would the fun be in that?.
