Embroidered Wireless Ball Inclinometer

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.
