Meant to be Seen

Hello mates

I just finished working on my DIY HMD and I tried some titles with it. I recorded a video of AMS (Reiza). The lens distortion is almost non-existent but it's the best for my HMD (so far), but since every single video upload I saw has a Rift-like distorsion, maybe I'm seeing things wrong now.

Please take a look at this video and share your opinions

The HMD was originally made for phones and it's probably not the best. Tridef made it stereoscopic and I used the VR shader (native) made by a nice guy from around here. The head tracking is done with Freetrack using the 2DOF method of 1 single IrLED. The screen is an 1080p 6" TFT I bought from Alibaba.

If anyone interested, I will add the pics I made during construction.

Any opinion/ advice would be helpful. This HMD is the only one I have tried so far.
Thank you.

the hardware/software components:

display: Topfoison 1080p with TC358870 HDMItoMIPI driver board http://www.aliexpress.com/item/DIY-VR-1 ... 21437.html priced at ~212EUR + customs
case: E-Boda Avatar 3D (romanian brand, probably produced somewhere in Asia) with aspherical lenses http://e-boda.ro/video/ochelari-realita ... r-alb.html - priced at ~68 Eur
S3D for gaming: Tridef 3D Ignition
Lens Correction: SweetFX shader http://www.mtbs3d.com/phpbb/viewtopic.php?f=120&t=21174

Cool. Do you have any photos of the device itself?

Here are some shots

Nice!

Thank you mate.
I kept tuning and I think I reached a certain immersion level, since I almost sh** my pants loosing control of a virtual F1 at ~300km/h, ending smashed into a wall.

VR needs a lot of patience and trial&failure but, even with 2DOF tracking, the result can be phenomenal. I waited years and years to have the time and resources to build such a toy.

This forum is the best resource for knowledge and you guys are awesome. The true brainstorming is here, not in corporate meetings.

It worths every drop of sweat.

I have one more upload, it should have a better 3d this time

I found out why my VR image is not (so) distorted: my VR case (E-Boda Avatar VR - formerly for phones) is using aspherical lenses and it seems these lenses are doing a pretty good job in canceling the distorsion.

Now, if I may, I will change this thread's title to something like "yet another DIY HMD" or something

Hi can you plase tell me how brightess and contrast controls work on the topfoison panel?

Yes they are working, assuming you're asking about the graphics driver panel controls

I have a suggestion, why not use two displays instead of one?
The two good headsets, HTC Vive and Oculus Rift, both use two screens for each eye.

Anyway, nice job on the HMD! I wish I had enough money to make one.

Well, the 1080p screen I use was around 250$ which I consider expensive.
Also, placing the perspectives on 2 screens needs serious work.
My screen is seen as a second display.
I am using Tridef for 3D which eats FPS for dinner.

I recently upgraded the headset with Shinecon v2.0 (~25$).
It's overall better than the previous, which had Fresnel lenses.
The Fresnel don't barrel-distort at all, but light pollution is really bad in high contrast scenes.
Shinecon v2 has classic lenses; they distort and have color aberration, but the image (ReShade applied) is crystal clear and the FOV is way better.
