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

Description

This month long exhibit also includes great works from local wearables artist Grace Kim, Hannah Perner-Wilson, and Leah Buechley.

Now that I have assembled one of the largest collection of e-textile materials and associated tools I am trying to figure out the smallest winning subset that can form a portable lab.

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.

This is assembled using hot melt adhesive backed conductive copper fabric.

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.

A loop of conductive thread is sewn on either side of the base fabric under the flaps. An inverted toggle from a clasp for jeans is used to short each conductor lowering the resistance of the loop.

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.

Iron on a small strip of the copper fabric to a non-conductive base. Cut the fabric, and fold over a small section and iron it to itself creating a small flap. Attach another piece of fabric, and iron it close enough to come in contact with the small flap.
