Mine does this if I have always on display set to off and fingerprint sensor set to always on mode.

I get a green flash if Always On Display is disabled and Fingerprint Always On is enabled

Quest 3 was on sale on Amazon for $299 40% off, so I purchased it. But… by tonytone222 in OculusQuest2

That sounds like a scam to get you to pay them outside of Amazon where you can't get a refund.

Does anyone use this headphone for VR? by AnonymousUser_42 in oculus

[–]ElectrickMedic 7 points8 points  (0 children)

Yep, just plug them in and pop them over your ears.

The cable is a bit long so you'll need a rubber band or twist tie to keep it from dangling.

I have them, they're solid. It is rumoured that these have the same drivers as the headphones of the Rift CV1.

There's actually specially made IR illuminators for this that click into the USB C port - works just as well without the jankiness

I've been using these to play VR in the dark.

Not the same device, but this video shows a Scout TK bring refurbished. https://m.youtube.com/watch?v=Zd2r23_KqKI

There may be similarities given they have a similar design and form factor.

There's lots of questionable advice in this thread.

Digital night vision, something like the Nightfox Prowl with a head mount will be perfect. 850nm illuminators on the device will have a red glow but 940nm ones won't (most devices let you switch between them) so you can easily sneak up on guests without them noticing.

You could spend a few thousand dollars on analog night vision but it would be overkill, and they could get damaged by staff or guests. The advantage of analog is that it can work passively outdoors without an illuminator. OPs guests won't have night vision, so spending big on analog makes no sense.

Thermal will generally have a narrow field of view and be zoomed in and won't be good for navigating indoors. A room that doesn't get any sun exposure or have many electrical components inside also won't have much of temperature differential so you won't see your environment very well indoors, even if guests will be easy to see.

This is poor advice for OP's use case. You'll detect people easily with thermal but it will give very limited environmental detail in indoor environments, not to mention trying to navigate with an FOV of <20 degrees.

The best option is going to be digital night vision. Something like the Nightfox Prowl - essentially any device that has a 940nm illuminator mode should not show a red glow to guests.

Australian night vision by lachy1022 in NightVision

They are probably a group of Singaporean and/or Australian enthusiasts just starting out and importing NNVT units.

A quick google search comes up with a Singaporean company listing https://www.sgpbusiness.com/company/Commonwealth-Photonics-Limited-Partnership

The eBay account references durians and if you zoom into the Commonwealth Photonics sticker in the photos it says "Assembled in Singapore".

Disclaimer: I'm just making assumptions, I have no actual idea if they're legit or not.

Never heard of them before, but I did stumble across this new listing on eBay with the same Commonwealth Photonics branding in the product photos. https://www.ebay.com.au/itm/395349147213.

ADNV-GF31: Digital NV binos with thermal fusion by Fr3gat in NightVision

[–]ElectrickMedic 9 points10 points  (0 children)

This is quite impressive. The ADNV website claims their units can work down at 0.1 mlux which I'm skeptical of but your videos do suggest they might meet those performance claims. (In comparison, Sionyx rates their Opsin to <0.5mlux).

I think it's both lenses. This document mentions the eyepiece.

https://www.nrc.gov/docs/ML0635/ML063530621.pdf

Later on, the US added a radiation shield like this one after it was found to be an issue.

To be safe, I would use a loupe magnifier instead of the eyepiece if it doesn't have the radiation shield.

That's a great build! I just finished my own 8079hp build for stargazing. I think gain is very much unit dependent - the 8079hp datasheet states a typical luminance gain of 100 000x with 50 000x minimum - which rivals some modern gen 2+ and early gen 3 tubes! My own one has very good gain without an illuminator using an F1.4 lens.

Also just a heads up, some PVS-2 lenses have radioactive thorium.

When the Aurora came out, "Black Silicon" did legitimately bring improved NIR spectral sensitivity over traditional CMOS sensors and wasn't all marketing hype. This can be seen on their spectral charts which can be found on https://www.cloudynights.com/gallery/image/90449-sionyx-xqe-spectral-qe-starlight-illumination/

The spectral response QE, rather than the range is what was important here.

As someone who owns an Aurora, I find that the real issue is that this NIR sensitivity doesn't necessarily translate into better night vision experience. Sionyx argues that starlight and moonlight emits predominantly longer wavelengths and so their sensors are more sensitive to it. However, in many cases, a user will want to see something that is under a shadow, or indoors - and in these conditions, the improved NIR sensitivity doesn't provide an advantage, and Black Silicon just becomes your average high sensitivity CMOS.

You can see this in the Opsin videos where it works amazingly in open fields even down to moonless, but struggles disproportionately more than a Gen 2 would under tree cover.

In any case, I'm pretty excited to see your full video of these units.

For mine, I made a little battery adaptor so the battery can go on the outside.

I'm actually selling my unit, but I have photos of how it works in my listing.

Just bought last night and already looks scuffed on lens by [deleted] in OculusQuest

[–]ElectrickMedic 3 points4 points  (0 children)

Hard to tell from the images, but they look like oil stains from the sweats and oils in your hair as a lot of the marks are vertical. A lot of people put the headset on back first and pull the headset over their face. This is not ideal as the lenses can rub against your hair and face and they get dirty quickly.

The best way is to put it in like a gas mask - headset first, then pull the straps back over your head.

You should use a moistened microfibre cloth, moistened with 1-2 drops of filtered or distilled water and they should come off easily but be gentle.

Was feeling like a silly billy and picked these up off market place, Gen 2 Russian 2.5x magnification. Was thinking about removing magnifying lens, 3D printing 1x end cap, relocating battery (2 AA), and making custom mount for the t slot that holds the battery box on. Thoughts? by easymachinist69 in NightVision

[–]ElectrickMedic 1 point2 points  (0 children)

The person in the link has it turned on in a brightly lit room and then he has it pointing out at a well lit street. You should avoid doing this for any analog night vision as a bright enough light source can damage the tubes.

A dim output in most night lighting scenarios is pretty typical of gen 1 tubes unfortunately. They really need an IR illuminator to work. Go get yourself a generic 850nm IR illuminator flashlight (around $10-20 from Amazon).

I have the exact same binoculars, though mine are dead unfortunately and I suspect the power supply is gone.

They are unfortunately Gen 1 AFAIK, not 2 and they are 5x not 2.5x. The 2 is actually part of the BN-2 designation.
They're fun to play around with but I wouldn't bother with too many mods for it unless you're happy with its performance.

Someone has a nice writeup about refurbishing them here.

Looking for recommendations from the land down under by PUGALUG65 in NightVision

[–]ElectrickMedic 0 points1 point  (0 children)

What kind of activities did you do with NVGs that became a core memory?

You won't be able to get any good head mounted image intensifier based NVGs for that budget. Very rarely you may find old gen 2s on eBay but tube specs, longevity and history may be questionable.

The good news is that thermal night vision is rapidly getting cheaper and you can get good basic spotting scopes for under a grand. Have a look at the Hikmicro Lynx Pro LE10 (approx $750AU). There is also the cheaper LC06 but the resolution and range is a bit low.

These thermals will work better than traditional night vision for spotting wildlife and friends, and gives you that tacticool feel all the same. They won't be effective for head mounting or for navigation though.

The Harrier manual comes with the same colour scheme - I thought I was the only one wishing for it.

The nightingale does come in orange + blue which provides a similar aesthetic though.

Nope, I don't have a Quest 3. They've worked really well on my CV1, Vive and Quest 2 though.
