SHKB v3

The third major rebuild of SHKB is based on the ITU E.161 international keypad standard.  This allowed me to shrink the overall size of the device while still maintaining its monolithic aspect.  In addition to A-Z, v3 can make a space, and exclamation point and a smiley.

SHKB v3 tech notes

Older versions of SHKB were dependent on a hacked keyboard logic circuit.  For this rebuild I moved to an Arduino Leonardo.  Programming behaviors from scratch gave me much more control.  What’s more, the Leonardo is automatically identified by the computer as a keyboard, and there are plenty of related libraries to get you started.  With this build I also moved to actual heavy duty switches as opposed to embedding strips of copper in my silicone casts.  We’ll see how long they last…

SHKB v3 @ AIC Curriculum Fair, Chicago

SHKB v3 on display at the Art Institute of Chicago.  The teachers of the curriculum fair were a surprisingly relaxed bunch, and were less interested in the practice of bashing than most audiences.  That said, I did have some great conversations about possible applications for SHKB in special-needs classrooms.  Another teacher also turned me on to TAB – an approach I’ll be evaluating as I keep working on the foundations curriculum at Columbia College.
