Thanks to Angela Sheehan from Soft Circuit Saturdays for filming this in the challenging, busy, noisy environment of Maker Faire.
A loop of conductive thread is sewn on either side of the base fabric under the flaps. An inverted toggle from a clasp for jeans is used to short each conductor lowering the resistance of the loop.
Piezoresistive fabric is sandwiched by sewn rows of vertical and horizontal pads using a basic sewing machine's custom embroidery pattern.
This wireless variant of Hannah Perner Wilson's fabric tilt sensor uses embroidereded high electrical resistance thread . I designed the tool path to create a resistive track from the patches that can be used as a potential divider . This results in a more continuous estimate of the ball location than is suggsted by the six apparently-discrete patches.
