Overview

  • CNCDan published the full design on GitHub, including 3D-print files, a bill of materials, and assembly guides for hobbyists.
  • The headset uses two 2.9-inch LCDs for a combined 2880x1440 resolution with lenses and other components sourced from AliExpress.
  • Head tracking relies on a GY-9250 IMU with an Arduino Pro Micro running the open-source Relativity VR stack for SteamVR integration.
  • Testing shows the displays run at 60Hz at full resolution despite 90Hz specs, and the creator suggests pricier 120Hz panels as an upgrade after fixing initial IMU drift in software.
  • The 3D-printed build includes an IPD adjustment mechanism and connects to a PC via HDMI for video and USB for power, drawing fresh coverage from PC Gamer, PCWorld, and Yanko Design.
