The current growth of the Arduino platform is fueled by the many new boards that make it easier to squeeze Atmega processors and their associated peripherals into ever smaller spaces or unusual places such as clothing.
Neather hoarding or fetishism explain my large and growing collection of Arduinos (official and unofficial) - I use them to test the sketches and libraries that I share and to teach people how to pick the best one for their applications in
These are built by sandwiching a piece of porous, spacing fabric (e.g. tulle) between two sheets of piezoresistive fabrics (from Eeonyx). For the square pad depicted below rectangular sheets are placed at right angles and wrap around the frame. On the inside they are stapled to a conductive strip on each edge. The four edges are wired to the analog inputs of a suitable microcontroller, e.g.
A hard ball is surrounded by crumpled resistive fabric (nylon and spande)x and trapped by a round ball of silicone with holes in it. Sensing in various orientations is achieved by wrapping conductors between the holes of the silicon ball.
I showed e-textile wearables, some of my materials collection and many soft circuits including
musical instruments. The wearable theme continues for the month of March. You can see many of the things I showed as part of an exhibit that includes great works from local wearables artist Grace Kim, Hannah Perner-Wilson, and Leah Buechley.
