HadesVR
The "DIY" SteamVR compatible VR setup made for tinkerers
... Knuckles controllers. The SteamVR driver used to be based on TrueOpenVR but it's modified so heavily I'm making it its own thing. This driver also uses PSMoveService (for now at least) for the positional tracking of HMD and controllers, using ping pong balls and different colors of LED's. The headset connects to the PC and receives rotation and button data from both controllers through RF, while the tracking is done outside-in (base stations) using Playstation Move Cameras and PSMoveService.
