Bluetooth Page Turner - Lyric Changer

Similar to an Airturn.com bluetooth page turner, I wanted to see if I could make a cheaper alternative. In an effort to keep an aesthetic that would match the style of music we play...i.e. bluegrass, I decided to make it out of wood. Using VCarve to design the file, I cut out the cavities in the wood block using the Shopbot at TechShop Pittsburgh. I cut two channels on the bottom of the wood block that you can't see in the picture so I could run the buttons between the cavities with out having to have channels on the top. 

For the electronics I used some simple push button tactile switches. These are momentary so they only hit once. The brain of this was Adafruit's Bluefruit EZ-Key. I wired up 2 switches for the foot pedals and 2 more. One for the Home button in iOS and one for Keyboard Toggle. Everything is concealed with small wooden pushers and a wooden lid. The wooden pushers are glued to insulating foam which acts as a spring surface. The wooden lid attaches using two rare earth magnets. I wired up a JST connector in the final version and attached everything using Adafruit's PermaProto Board. I love these permanent breadboard-esque prototyping boards!

I currently use the app "Setlist" with the pedal. It does a great job at turning the lyrics so we can have a ton of songs in our back pocket with out having to memorize the lyric. As a Bluegrass band, a lot of songs are easily remembered but the lyrics are the hard part!
