The Piano Pen
It's a musical microcontroller on wheels. A row of light sensors on the bottom tell the thing when it's rolling over notes, and the speaker burps out the corresponding notes.
It can read a simplified musical notation, and can also be used to read from things like black magnets temporarily applied to a baking sheet for quick composition. These compositions could be scanned or photocopied to share.
The speed at which the Pen is rolled over notes governs tempo.
Questions
- What's the best way to sense light?
- light sensitive resistors, transistors?
- How big of a clef could it support?
- How big would notes need to be?
- What microcontroller best suited?
- it needs to be able to generate tones and collect inputs from the light sensors
Ideas
- Dial-a-key
- Transposition
- Recording
- Computer interface
