This session will provide an overview of Electronic Textile (E-Textile) Toolkits. These are microcontroller boards and associated components specifically intended for use in textiles, usually with conductive thread. This will include current platforms such as LilyPad, Flora, Gemma, and Circuit Playground Express, as well as past platforms such as FabricKit and Angiomagic. By looking at past and present toolkits we can think about what makes and e-textile toolkit viable and what kind of tools we might want in the future.
