This project is a force feedback joystick with multiple strain gauges on the stick interface. The gauges worked very well, but I've lost interest in the project, so don't expect any updates.
I'm providing the 3D CAD files of the structure as I used it, along with the E-CAD files for the control board. These files are not polished — if you want to build this yourself, they will not be enough on their own. Treat this as a work-in-progress snapshot rather than a finished build guide.
