2015-08-02 (Su) Wrist Mounted Chording Keyboard

Plans were made for a thumb board which would hold three buttons. Three raised nodules were modeled which would each hold a buttons and designate a particular distance between them. Holes for the bolts were spaced the same as the receiver piece modeled previously. Holes were angled to allow countersunk bolts for lower clearance and a cleaner look. Eight small holes were added to the design which do nothing more than reduce the amount of plastic necessary. Removing these holes can be done by downloading the OpenSCAD code and commenting the holes out.

A print was made and buttons were set on top of it. Once glued the buttons should be secure but the design should be changed to include a divider between the switches instead of relying entirely on the glue. While holding the keyboard and adjusting the position it seemed more logical to angle the key levers up rather than down. Angling them down suggested a relaxed feel but the hardware will likely rest lower down than the wrist rather than in the palm.

To do:
  • Revise model and reprint
  • Add electronics
  • Figure a way to mount
  • Figure a way to move hinge pieces
  • Make model and OpenSCAD code public
  • Write keyboard code
