The new Lilypad MP3 board is out and it looks pretty sweet! Lilypads are washable Arduinos designed for wearable electronics. You can sew them onto your clothing and wire them up with conductive thread. The new MP3 board is basically an Arduino — it’s got the standard ATmega 328p with Arduino bootloader. However, like the WaveShield, it can play MP3 sound clips from a MicroSD card. It has five trigger inputs and when grounded, each plays a MP3 clip using the code preloaded on the ATmega — but you have to have speakers wired in! I love the fact that they have the footprint for a RPG rotary encoder in the middle to do more advanced stuff.
