Tell us about yourself!
Hi. I love this! We made a similar thing for a children's museum many moons ago. In our case, we ran the contacts to a MIDI footswitch controller, so we could turn each key press into a note on / note off signal to a synthesizer. I was thinking about this recently, as I am working on an Arduino project that does something similar - turns switch closures into MIDI note data. Maybe I'll Instructablize it when I'm done. Would make a nice companion project.
Thanks! Happy carving!
Thanks! Happy Halloween!
