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.

Pervasive Cameras: Making Sense of Many Angles using Radial Basis Function Interpolation and Salients Analysis

Yotam Mann, Adrian Freed

Abstract. This paper describes situations which lend themselves to the use of numerous cameras and techniques for displaying many camera streams simultaneously. The focus here is on the role of the “director” in sorting out the onscreen content in an artistic and understandable manner.

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.
