The StyloCard Is A Business Card-Sized Synthesizer
The StyloCard is a Stylophone-style, credit-card sized synthesizer that supplies a range of 20 notes. All it needs is some USB power and its ready for action!
Tim Alex Jacobs, the creator of StyloCard, describes the project:
I can’t remember quite how I got the idea of making a MIDI-stylophone, but the idea was perfect. A working midi controller, that’s unique enough in its playing characteristic to potentially give some value, while at the same time costing no more than the card would have done otherwise, since the keyboard is just a plated area on the PCB, as is true on the original stylophone.
