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!

Nicely made! Two different kinds of wood make it look really sweet.

Just used the Bluefruit graphical interface to map one of the foot pedal buttons to a virtual keyboard stroke?
(I tried it, but I couldn't make it do exactly what I wanted to do).

Could you leave the "technical side" of the project ? I'd like to do something just like that, but I'd need the code for it. Thank you.

    I am a maker at heart and electronics enthusiast. Many of my projects are created out of necessity for the item, or out of a modification of existing things I have!
