Fans of Douglas Adams will no doubt catch the reference to The Hitchhiker’s Guide to the Galaxy in the title of Becky Stern’s latest project, The Babel Fish Language Toy. This sound- and RFID-enabled Arduino project with a crafty enclosure helps you learn foreign languages with RFID flash cards. When you bring a flash card near the fish’s tongue, you’ll hear the pronunciation of the word, which comes from .WAV files that you pre-load onto the SD card. And naturally, a full how-to writeup and video will help you along the way should you decide to make your own. Xie xie Becky!
