With the release of the Vive trackers, I decided to start prototyping some ideas for haptic and force feedback hardware to be used in conjunction with the InductVR app.
Besides their smaller, more versatile form factor, the vive trackers allow for some basic input/output functionality meaning they can be used for wireless communication between any sensors, arduino, or pi controllers and your main VR application.
By shorting the ground pin (2) with any of the other pins (I used 4 here) on the vive tracker you can emulate the usual controller trigger/grip/menu functions.
After this initial test, it was time to start building something a little more interesting
