Kevin has a great discussion with XMIT in this One on One interview about the Hall Effect Keyboard.  Design considerations, along with the journey, plus a little more technical detail in how the Hall Effect is used to create a switch brings a much clearer picture into where this board came from, to where it is going in the future ahead.

 

Thank you very much to /u/XMIT and /u/thesircheddar for bringing this great interview to us.
