VR Lens Testing Rig

thingiverse

I purchased some lenses from Amazon to test whether they would work to create a VR Cardboard goggles setup. I had already designed a basic frame, but it lacked adjustability in terms of the spacing between my eyes and the distance away from my phone. The first task was to see if the lenses could be calibrated properly to provide a seamless viewing experience. It turned out that calibrating these lenses proved to be a bit of a challenge. I decided to focus on making some adjustments so that the lenses could fit properly in my makeshift goggles. To make the lenses fit better, I used Amazon's B00EPQ9EVQ model. Unfortunately, the sizes varied from 39mm to 41mm, whereas the perfect size for me was around 38mm. Despite this issue, they still managed to provide an acceptable viewing experience when using the Cinema VR app on my phone. Next, I plan to create a more robust design that's similar to Google Cardboard but incorporates OSVR diopters instead of regular ones. These offer better functionality and would be beneficial for people who wear glasses like myself. My ideal setup will need to accommodate various phone sizes, including both larger and smaller phones. A potential addition I'd like to include is a means of integrating headphones via the headphone jack. Another feature I'd love to have is an OTG cable to enable keyboard and mouse usage while wearing my VR headset. I've included my FreeCAD design files if you're interested in replicating this setup with the same lenses I purchased.
