Myopia vs Presbyopia (short Sight vs Long Sight)

Hi Starraker,
I haven’t got around to installing springs yet. Actually the unit is working well at the moment and so I’ll just stick to it as it is for now.

The fibre washers I used worked out to about 2mm thick when three were stacked. This worked out to be about right for my vision. I seemed to have fluked it first time. However I do wonder if I it were possible to adjust it a bit further so I don’t need to wear glasses at all.

I suspect it is possible to go too far and narrow the field of view even further.

You will need to get longer screws to hold the lens holders in place as the ones belonging to the lenses will be too short when the spacers are used.
The screws that attach the face bezel are about the right length.

Don’t forget. Don’t power the unit up before you put it back together again. Some have triggered a security lockout by doing that.

Good luck with it. Let me know how you go.

Cheers, Luke

Heliosurge and CreDo,

Thank you. I will let you know what their answer is

LukeB,

I ran into a snag there are no discernible screws in the case of my 102 HMD so I thought that I would pause a while to see if an optical solution exits - refer to the Heliosurge and CReDo advice.

I will let you know if the company will make lenses for PiMax 4K. As they make for most of the other I cannot see why they would not - especially as the Vive lenses are so alike.

Heliosurge, LukeB and CReDo,

I have received a reply from vr-lens.com and this is the text:

"Sorry that we only offer adapter lenses for Oculus Rift and HTC vive at the moment. You might be interested in our new VR Frame that can be used in different headsets: https://vr-lens-lab.com/product/vr-frames-virtual-reality-glasses/

VR Frame is narrower compared to regular glasses but we never try them on the headset model that you mentioned, so we can’t tell if they can perfectly fit into your headset."

They have not precluded lens manufacture for PiMax 4K in future but nor have they said they would.

So the LukeB suggestion is still the best (barring a reply from PiMax support). Does anybody have instructions on how to get the 102 series HMD body apart with destroying things - I have only seen the video on the 100 series (with screws)?

that is without destroying things

I had actually mentioned this company in the past and found that they only make correction lenses for Oculus and Vive headsets.

I had asked if they would be interested in also making some for Pimax4K but they were not interested. They have put all their eggs in the Oculus Vive baskets.

They don’t strike me as a very smart or progressive company ignoring the larger part of the vr market from Chinese manufacturers.

I had also mentioned this company to Pimax support but never got any reply from them.

I’m getting the feeling that Pimax still does not appreciate the importance of including mechanical focus in their units as I have never seen any mention of this in any of their posts.

Can you post some pictures of your unit so we can see what is where the screws are on ours?
There must be some way to get it open.

There is a recemt discussion “lcd panel type” the 102 serial tear down appears to be the same as the 100 series.

@Heliosurge @LukeB Yes, I noted you guys’ discussion and good suggestion. As you know, this issue refers hardware and new moduel, so I can not give out a positive reply for you guys until hardware engineers tell me a further progress :slight_smile: But I will continue to follow it.

Ok, thanks for the feedback.
I look forward to hearing what your development engineers intend to do about this important issue.
Cheers, Luke

Awesome news! As one user mentioned probably best to have new design for “normal vision” then have prescription lense add ons.

@deletedpimaxrep1

One thing that would be wicked as well is if the defogger wire could be made thinner. Squarish lenses may help with fov.

If using lcd panel would be cool if use a 21:9 panel.

Something your team should look into is this! Forget laser tracking.

There is a link in diy positional tracking for structure sensor

LukeB,

I have attached some hi-res photos of the 102 :slight_smile:

I hope they give you enough to go on

Well it looks the same as mine.
Are you sure there are no screws that keep the face rubber surround (pic 1) onto the body?
You have to force the rubber out of the way to see them.

I got this video from Pimax support several months ago and I decided to put it onto YouTube so others may see it as well if needed.

It was a help to me before I tried to take my Pimax apart.

Cheers, Luke

LukeB,

Your video comes up as private and will not let me play it.

I explored further but my rubber face mask is Velcro’ed on to some very hard plastic hook material and with considerable force I was able to lift the hard plastic in one place in the area half way between both eye pieces but this revealed no screws. This model is really well built and has the appearance of being glued together.

There might be screws there but they are well hidden

Sorry about that. It should play now.

Well it may be worth having a chat to Pimax support and see if they can suggest how to take the HMD apart.

I would think that there should be a way so it can be serviced/repaired.

Good luck with it.
Cheers.

LukeB,

Thank you for the video. It is much clearer what I should be looking for. I will let you know how I go

Thanks for this

Cheers

Hey LukeB,

I found the screws ( I wish I hadn’t)

I tried and it died. I just converted a working display into a one eyed non working HMD.

I still have the blue light on top but only the right eye is showing any life. Unless the debug fixes such things (because I cannot read Chinese) the PiMax 4K has gone to the happy hunting ground.

Thanks for the attempt to help.

Heliosurge,

The tear down is the same for both models.

Unfortunately I converted a working HMD to a non working one eyed beast. No more VR for me
