DIY YouTuber CNCDan has uploaded a video of his latest project — a VR headset, which, besides the 3D-printed parts, cost him about $150. He also made all the resources needed for the project open source.
Looks like it has an inertial sensor to control the view, here’s there relevant bit from the article:
The parts he purchased online include two displays that max out at 2880×1440p and 90 Hz refresh rate, two lenses, an IMU (Inertial Measurement Unit) sensor, and an Arduino microcontroller board. The other parts of the headset were 3D-printed.

The headset features individually adjustable IPD, interchangeable faceplates, and head tracking. But it does have downsides — at full resolution, it only runs at 60 Hz. Also, it only has three degrees of freedom (3DoF), which means it tracks looking up and down, left and right, and tilting the head left and right. He explained he didn’t bother equipping it with 6DoF as 3DoF was enough for his sim racing.
