[...] A sip-and-puff can make a world of difference to a quadriplegic, but they’re not exactly cheap. So to help out a friend, [Jfieldcap] designed and built an open source sip-and-puff mouse on the cheap. As is best for such devices, the design is simple and robust. The hollow 3D-printed mouthpiece acts as handle for a joystick module, and a length of tubing connects the mouthpiece to a pressure sensor. An Arduino lets the user move his head to position the cursor; hard sips and puffs are interpreted as left and right clicks, while soft mouth pressure is used for scrolling. In conjunction with some of the accessibility tools in modern OSes and personal assistant software like Siri or Cortana, the sip-and-puff opens up the online world, and for all of $50 in material.
