    Knit Ball Sensors

    A series of balls knit on double-bed flat-bed knitting machine that incorproate conductive and resistive yarns to allow them to be stretch, pressure, scrunch and touch sensitive. Using lilypad Arduinos with FTDI and USB cables as well as ATtinys with Bluetooth to send sensor data to computer for visualization and sound feedback.

    Balloon Ball (6 Capacitive Sensors with Resistive Yarn)

    Interesting observation: because the contacts are knit from a restive yarn that decreases resistance when stretched or pressure d(becomes more conductive) the capacitive trigger thresholds are also dependent on conductivity of material, so that sensor areas might not trigger, unless material is manipulated (stretch, pressure) to make it just that bit more conductive.

    Using a LilyPad Arduino to read 9 capacitive sensors and either visualize and sonify the sensor data via a Processing sketch, or simply trigger tones played through a speaker connected directly to the Arduino.
