Remove the lid of the Piano Box and three sides fall flat against the table top, two hold speakers and the other features a touch sensitive 12-key piano/synth keyboard
Portugal's Catarina Mota has created a 12-key synth with note-responsive LEDs from paper, some electronics and open source and custom code
At the heart of the Piano Box is an Arduino Mega microcontroller running CapSense and Tone libraries - each touch key is mapped to its own LED light
When the user touches the paper-covered copper tape, a corresponding LED lights up on the vertical panel to the rear
Catarina Mota at work mixing electronics and smart materials with low-tech materials such as paper, fabric and edibles
Last year, Portugal's Catarina Mota was part of a New York hackerspace team that created a toy piano made from Jell-O (and some electronics) for a competition in Brooklyn, NY. Being a lover of mixing electronics with low-tech materials like fabric and paper, she has now created a paper box that opens up to reveal a 12-key touch piano/synthesizer sporting some cool LED light action. The Piano Box is built around an Arduino Mega board running the CapSense and Tone libraries, and features twin speakers, capacitive keys made from paper-covered copper tape, and some custom code that's available for free download to allow anyone to make their own paper synth.
