1) Create a tactile interface in a small form factor that can be used in conjunction with a smartphone.
2)A Smartphone based Braille trainer.
The intention is to create a better interface for a smartphone for the visually challenged.
The secondary goals are:
1) Opensource Electronics
2) Cost effective BOM
3)3D Printintable design
Good project, however, the PCB and case do not match up. I cannot find a file for the new PCB design. Would like to put this project together.
