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.
I am wondering about the software side. Is it just a glorified monitor for your face, or does it have some kind of internal control/OS like a Quest or other commercial headset?
It seems to only have an Arduino as processor, so presumably the former i.e. you need a PC to plug this into. It seems to have highly simplified tracking compared to something like a Quest - a single Inertial Measurement Unit. All enough for sim racing which is this guy’s jam, but I wonder how well the tracking stays calibrated.
The critical thing with these is response time. If it’s even slightly too high (I think 20-30ms is easily too high), some/many people get very motion sick. Getting that time down as low as needed is also not trivial.
With it only being 60 Hz on the controller itself, that’s basically impossible to hit. That’s 16.6 ms already. Then the processing, sending to the PC, and the PC reacting has a budget of just a few ms? Yea, not happening.
I’m assuming he’s really not sensitive to this. As it’s open source now the people who are sensitive can improve it. That’s the beauty of open source after all.
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.
It relies on the Relativity VR driver so theoretically similar software support, namely https://github.com/relativty/Relativty#14-software-setup but mind you beside being 5 years old this is 3DoF, no controller or hand tracking, whereas the Quest is 6DoF, namely you can move around, not just turn your head.

I bet I could use it. I can play the VirtualBoy in a moving car. If there’s any kind of way to tie it into MechWarrior, I want to build one.
Normal video games can make me motion sick so I can only imagine how bad this might be! Maybe in the future it’ll get better!
I’m wondering if I wanted to fly a jet, would I need another sensor for 3 dimensional tracking
