Want to be sure you’re playing musical chords correctly? This unit will tell you if you are and display a light show in the process. I stumbled upon this circuit while trying to design a custom frequency tuner for my guitar and is hands down the best sound to light device you could ever build.
Now, while I’m sitting in my favorite chair, I can listen to Internet radio stations or play artists, albums, or individual songs from a Flash drive plugged into my Raspberry Pi. Get step-by-step instructions on how to turn your RPi into a remote-controllable Internet radio/music file player.
