I love small keyboards, but with only 3 keys, you may as well just send ASCII codes. Nitpick aside, this does appear to be a quality project. :) A design document, user manual, and graphical simulator are lacking in many other niche keyboard projects.

It does just send ASCII codes (well, USB keycodes)! It's not supposed to be practical, just to be technically interesting and useful to learn from!
