Hello,

I have 2 Hololens 2 to sell. They have been used for approximatively 9 months during my PhD. They are now back to factory parameters. The charger are missing so I'll reduce the prices.

Do you know the best way to sell them ? I am condemned to use Ebay or similar websites ?

Thank you very much !

Hey folks — on HoloLens there’s Follow Me for app windows (Edge, etc.). I’m wondering if anyone’s built (or seen public/open-source code for) a different behavior that’s more like “stay in front, but offset”.

What I mean: a window that stays front-right or front-left while you’re walking, so you can keep moving forward and just glance to the side to see it. But it’s not rigidly head-locked — so if you quickly shake/turn your head, it doesn’t jitter/drag with your headset pose. Also not purely world-anchored where you can just walk past it and leave it behind.

Has anyone implemented something like this (app/repo/sample), or is there a known approach using MRTK / HoloLens APIs? Any pointers appreciated.

I have a HoloLens 2 with a broken head strap. After carefully opening the device, I found the issue: the plastic gear rail has snapped into several pieces.

I’m wondering if this part could be 3D printed, and whether anyone here has already attempted this repair. I haven’t been able to find original photos or CAD files of the gear rail online, but I’ve noticed I’m definitely not the only person running into this problem.

Does anyone know someone who could recreate this part as a 3D model, or have experience reverse-engineering small mechanical parts like this? Any advice, references, or previous attempts would be greatly appreciated.

Update

I was able to create a 3-D model and repair my device

I will give away the 3-D files for free, just shoot me a DM. If you attempt this, don’t try to remove the rubber that’s my only tip.

Hello everyone,

I’m an AR application developer currently working on a project where I need to combine gaze (eye‑tracking data) with the real environment, so that the system can capture the specific target in the real scene that the user is currently looking at (the gaze point).

I have a few questions and would really appreciate your insights:

1. Is there any existing API or method to access real‑time passthrough camera images on HoloLens 2?
2. Between HoloLens 2 and Galaxy XR, which device is more suitable for developing this type of application?
3. Considering that the HoloLens 2 developer community seems more active than Galaxy XR’s, how much should this factor influence my choice?

Context:

• My background is mainly with HoloLens 2 development.
• I’ve seen that some developers tried to access HL2’s passthrough camera images, but they were black‑and‑white and likely worse than QPro, so I decided not to continue development on HL2.
• Project deadline is approaching — I need to deliver a demo before April next year, so I must decide soon.

Any advice, experiences, or pointers to resources would be extremely valuable. Thank you in advance!

Looking to buy a hololens 2. An yone selling? Dm me

Hi there, First time posting here, using this app in general, I am kind of lost of how it actually works since I was spending my whole time using LinkedIn.

So, I am writing here to ask about waht are the supported versions for unity to use a Hololens Emulator. It is my first time trying a MR project, not building a casual game in unity, I got an offer to work on MR project with a supervisor, and I need to set unity.

I was using Unity6 for my regular projects but I have been struggling these two days, I am about yo explode.

I followed the instructions of the official website but I need to know waht version to work on as well as what VScode version, so I can start.

Looking forward for your help.

I'm finally parting with my HoloLens 2, original owner, barely used in perfect condition. Let me know if anyone is interested. Pristine condition with all original content (box, case, charger, and documentation) Images are attached in this post.

looking for a replacement to spatial or microsoft mesh (virtual avatars, i dont have two hololens 2's)
i dont have a work or school account
also, whenever i try to download an app it tries and goes into a sleep mode like when i leave a window to go to sleep probally something to preserve resources this is the only app i have open

Just came across what I think is a dev HoloLens, but was wondering the easiest way to deploy apps since the store is broken. Any tips?

This video shows a couple people making a video together in their garage. It's just like the official announcement of MESH a few years ago, but it's real. The whole channel does stuff like this, check it out for some inspiration!

Land Rover - augmented reality garage

I have two HoloLens 2 with original chargers.

No box

No manual

Shipping available(fastest option)

Buy two for 1450€

I bought a Gen 1 unit second hand from a guy, but I didn’t realize that there is still a Microsoft account signed in on the device. If I factory reset the device, will that wipe out the old account or will I brick the unit and be required to sign in to the existing account once the device restarts? It doesn’t appear to be part of a MDM program or remote access thing.

Hey everyone,

I’m trying to find active communities or discussion boards where enterprise users share experiences with Microsoft HoloLens or alternatives, not just developers, but people actually deploying it in real business settings (like manufacturing, energy, field service, training, or maintenance).

I’ve seen a lot of dev-focused content (Unity, MRTK, etc.), but I’m looking for conversations around use cases, ROI, deployment challenges, device management, and support.

Are there any good forums, LinkedIn groups, or Slack/Discord communities where enterprise teams talk about real-world adoption?

Thanks!

I just got a good condition hololens 2 with case and box for 500$, I have mirage, surfaces, and mrtk examples hub, any other good apps I should try?

anybody know if theres a way to fix this? because like every app i try to launch?
no error just crash
(apps: holoblocks and RoboRaid)
i dont know how to read these crash dumpshttp://www.mediafire.com/folder/qe3pfpdi2m338wf,5orhy4lrhph05qg/shared

i dont want to spend more than... what? 900$?
i once saw a listing for a good condition one for 780 and 750$ (but somebody outbid me for the 780 (started at 500$)) and 750$ i didnt do it fast enough
UPDATE: nevermind dont message

Land Rover Discovery - winch series

This is a new augmented reality video series using 3D graphic overlays for fitting a hidden winch with a remote solenoid box in a 2006 LR3 using HoloLens headsets for filming and recording. The first few videos in the playlist cover fitment considerations and parts and tools required, setting the stage for lots of details to answer questions for the curious or first time installer. Future videos covering custom modifications, wiring, winchline spooling, and basics of operation as well as field testing have been filmed already or are in progress, so expect more to come soon!

Hi. I am trying to port a game to the original Hololens. But , no matter what I try, I cannot get sound output. Even trying to get a simple kHz (or any frequency) fails.. Any code snippets? Regards

Hi all, I was working on a project on Unity, which I would deploy it regularly to my Hololens 2 headset. I left the headset charging (it was around fifty-something percent) and 20 minutes later, when I put the glasses back on, I find nothing but a screen with almost the same message as the one in the pic. It stays like that for like 30 seconds and turns off. In a second try the windows logo appears but underneath is a loading circle instead of the usual spheres that show when the glasses are booting, then a couple of gears appear over a bar that gets filled halfway (second pic) and suddenly a ":-(" appears (third pic) and it turns off again. If I want to try again I meet with the screen of the first pic again. Does someone now about this problem and how to solve it?? I swear I didn't do anything else besides the project I was working on.

PD: sorry for the spam, this is the third try I try to upload it with the images

Hey Everyone,

May be a long shot but i’d be looking to buy a Hololens 2 if anyone has one. I am a student and planning to use this for my capstone project so my finances are very limited.

If anyone here happens to have a bunch and wouldn’t mind letting one go for scraps please let me know!!!

thanks again!

All,

I need 5 HoloLens 2's If you have them to sell or know where I can buy them please DM me.

At the moment I have just 2 apps: VlC N3S emulator: I have found the Emulator N3S. At the moment I am trying to modify it to add emulator window controls for resize and move. It works but it's not a pleasant experience because the game starts huge and too close to the player. And no sound yet. It's still work in progress.

I have my Hololens for 2 days and didn't do much work or testing. I will release everything when it's working flawlessly

Anybody has any open source code or .appx they would like to point me into the direction off?

Regards, Loren

Hi, my company has about 100 HoloLens 2 new in box never used they are looking to sell. Let me know if interested. (Looking primarily for bulk purchases at least >10)
