DoraTouch is an opensource inexpensive touch/pressure sensor that provides home brew robots the ability to sense things they grab. It's part of the DORA Opensource Robotic Assistant project.
DoraTouch's design is based on takkTile's idea of turning MPL115A barometer into touch sensor by substitute air with rubber. This project is under active developing as part of DORA, so we don't have a complete opensource plan yet. However we keep updates the progress in a blog form.
