New post on my blog: I built a joystick using a 2-layer PCB and some strain gauges. The #StrainStick works very similarly to a TrackPoint. There's also a small demo software that lets you use it as a mouse by connecting it to a CH32V203 dev board.

The Strainstick is a joystick which works by measuring pressure, not movement. It can be built from a single 2-layer PCB and a couple of cost effective parts.
