Hi all. I've searched "free-track" on this forum and I got no results. Maybe the search algorithm can't deal with the dash, but just in case...

...did you know the "Free-track" project? It works with three leds on your hat and a camera. It seems working also with three ir leds and wiimote ;)

I suspect I'm not saying anything new here, but let me be sure of that, because it's a cool project with same purpose of DesktopVR.

Let me know
