Last week the world of wearables lost the light of one our shining stars, Valérie Lamontagne.

I invite you to celebrate her life by reading, citing and responding in your own way to one of her major life’s works: her 2017 dissertation: “Performative Wearables: Bodies, Fashion, and Technology”.

She covers some examples used in her dissertation here: https://vimeo.com/196041125

In the usual approach to PCB layout traces are laid out to connect signals and power to the pads of packaged parts and I/O connectors. This is a style that evolved for very high speed digital circuits. One usually also employs ground and/or power planes or a ground flood.

This style is not convenient for eTextile Appliqués which are most commonly single-sided and are based on cut traces rather than etched boards.

The entries in this table with an * were briefly reviewed in the 3 hour workshop the 2018 eTextile Spring camp. As the table shows, these are in the middle of the affordability/complexity/size axis and were selected for their potential in e-textile and wearable contexts. We had the good fortune to have Bela well represented in another workshop at the camp. Bela is transitioning to a new compact form factor which will make it easier to use with e-textiles.

Here is a non-electronic relaxation oscillator:

Description:

Rectangular grids are dominant forms in electronics and textiles. Triaxial grids have not been explored in e-textile work so this breadboard is offered to begin these explorations. Triaxial grids sample the plane with higher density and the availability of whug connections as well as warp and woof simplifies circuits by providing a natural power/ground/signal triple.
