    This workshop is only open to Madtech students.

    Dissecting Parts and Sewing Them Back Together

    Electricity will gladly flow through all kinds of conductive materials in an endless variety of shapes and sizes. Yet we build our devices from a limited set of components, and the results look frighteningly similar. A kit-of-parts approach to assembling electronics from discrete components is good for quickly and efficiently building similar things. But as makers and designers we’re interested in exploring the full diversity of possibility.

    In this workshop we will dissect discrete components to investigate their inner workings. What materials are they made from? How are they constructed? Once we have gained an understanding of their electrical abilities, we will proceed to remake their functionality, drawing upon a diverse set of materials and techniques. Our pool of resources will include newer materials such as metalized fabrics and threads, as well as common conductive items such as pencil graphite and paper clips. For working these materials into functional forms, we can draw upon age-old techniques such as knitting and weaving, but also employ the use of CNC machinery. Your skill and ability to master new crafts are the limit.

    Throughout this whole process of taking apart and remaking, we will be extremely methodological. Probing unknown material properties, drawing and photographing what we see, making small experiments before attempting to solve a complete system. The goal is to acquire new knowledge through observation and experiment, to mix this knowledge with existing skills in an inquisitive and creative process that will result in a greater electronic diversity.
