This git has been updated for my Version 2 DIY VR design. All of the original files are still here, they've just been renamed to V1.0 if they are no longer in use (along with the original Readme).
I have included a full model of both versions in .STEP format to aid with assembly!

First, you'll need one of every part printed, except for these items that require multiples:
3x DIY VR Buckle
2x DIY VR Lens Retainer
2x DIY VR Thumbscrew Head
The files with V1.0 names can be ignored, unless you are specifically making the old version in which case, you can print them and disregard any V2.0 files. Refer the to V1.0 readme for specific Instructions.
There are print recomendations for most of the important parts in the first video. The V2.0 front cover is much easier to print than V1.0 and can be printed front down with minimal supports.
Only three SMD parts are required to assemble the PCB, 1x MCP1792-3302xCB and two 470nF 0603 Capacitors. The two NRF modules can be soldered in as usual, but when you solder in the IMU module ensure you remove the black plastic spacer from the pins to ensure the module is sitting flat against the PCB. The Arduino needs to be installed WITH the black plastic spacers, otherwise its USB port won't align with the opening.
Once the head tracker board is assembled, there are three sets of pads you will need to connect. The two pads labelled "Calibrate" are to be wired to the tactile switch on the side of the headset. The three pads labelled VCC, GND and DO are to be connected to an addressable RGB LED that is used for the pingpong ball. The final two pads labelled VCC and GND are to supply power to your display driver and should be connected accordingly.
Revision 2.0 of the head tracker relies on the HadesVR driver. I have included a slightly modified version of their firmware here, which you will need to use as it adds support for the addressable RGB led used for the tracking bulb.
Refer to the HadesVR github page for upload and config instructions: https://github.com/HadesVR/Basic-HMD-PCB?tab=readme-ov-file#uploading-the-firmware-and-calibrating-the-sensors
If you're using the 6DOF tracking, you will also need to go through the PSMoveServiceEX Setup process. Their documentation is here: https://github.com/Timocop/PSMoveServiceEx/wiki
Refer to both of the project videos for build steps and I will add anything here in future if anyone requests extra information!
