    We support the Open Source Hardware movement. All our own designs published on this website are released under the Free Cultural Works definition

    Felted Pompom Pressure Sensor

    also see: conductive pompom, pompom tool
    Make pressure sensor ball by felting a pompom composed of wool and conductive steel fibers.

    Using the pompom making tools (or make your own from cardboard) to make a pompom from a mix of regular wool (real woo, not polyester!) and Wera-Tech’s Nm 20/2 composed of 70% laine (=wool!) and 30% Inox steel fiber.
    Once you have the pom pom, rub it between your hands with soap and hot water (or put it in the machine). keep rubbing until it felts, giving it a lovely squishy feel to it.

    Thanks to Hilary Grant for the tip on the technique of making felted balls from pompoms. You can also throw your pompom in the washing machine to felt it, but i did it by hand because I don’t have a washing machine at my work (yet!).

    Pompom making sound!

    Here is a video of the sensor results (the pompom is still wet!)

    Process of making

    Add soap and hot water

    Soak and rub between hands

    Dry off with towel
