I was finally selected for my first RoadTest! I've already got just the project to use the CapSense with, but I'd love to hear how the rest of you roadtesters are using it (or how would have if you'd gotten one).
I'll be using it as the input device for a braille teaching aid, adding a small pip on each of the buttons and possibly hooking a tiny rumble motor for haptic feedback. I'll update below with my plans once I've finished digitizing them.
(I really hope this is the proper way to use a document. If it isn't, please let me know.)
