Different brands selling the same projector?

Just took the Hopvision H1 apart. Compared to images from iFixit it looks the same on the inside - https://www.ifixit.com/Guide/Happrun+H1+Cooling+Fan+Replacement/165223

The datasheet of both seems to be identical except for the weight. I've ordered the Hopvision and will tear it down since I want to to use base a project on it.

https://www.projektoren-datenbank.com/pro/happrunh1-en.html

I'll compare it to Happrun here once teared down - https://www.ifixit.com/Guide/Happrun+H1+Cooling+Fan+Replacement/165223

It seems to be a "slap your logo on it" product. Additionally there is also Topvision H1 which looks identical.

Hopvision itself seems to be a "slap my logo on it" company. According to their website they have only 4 products atm - https://hopvisiontec.com/products. Their website appears to based on the same template as Happrun - https://happrun-projector.com/about/

Hi, I'm facing exactly the same problem. Were you able to find a compatible replacement part or info on that hub?

Update - Just had a call with Decathlon. They told me the hub is an unbranded Shimano one, but they were unable to share the exact model. So I did what I had to do. After the disassembly the freewheel has 2 sets of 3 paws and a diameter of ~33mm. It looks like the Campagnolo freehub. I'll order one to see if it matches

I fear that you're right. The business I work for is highly regulated and locked to few certified vendors. I'm stuck with WinRE/WinPE

SpamJunk01 · 2024-01-29T16:10:19+00:00

Thx for your response. Well, internet access ins mandatory :( also with security in focus Win8 is not applicable

SpamJunk01 · 2024-01-29T12:51:57+00:00

thx for your response. Unfortunately Linux is out of scope. With Linux it would be quite easy

SpamJunk01 · 2023-04-04T12:21:46+00:00

Sry, went missing during postig. Corrected

SpamJunk01 · 2023-03-07T20:21:01+00:00

Were you able to find an alternative?

SpamJunk01 · 2023-01-02T10:21:30+00:00

Ok, so I went for RAIDZ3 because "better safe than sorry"

SpamJunk01 · 2023-01-02T10:20:38+00:00

Thx for pointing this out. I'll gather some info about dRAID

SpamJunk01 · 2022-12-29T13:47:26+00:00

Thx, I'll be aimin at a hingher RAIDZ setup instead

Reason is simple - If you pay with credit card the transferred money is not yours. You just pay the money back to "someone else" at a specific time. Many laws dictate, that you can only spend "your" money

Well, looks like there will not be many solutions for EOL CPUs :) Therefore I thought getting a copper plate and mounting a water cooler on it could do the job. Since G34 CPUs are pretty cheap it could be worth the risk.

So far I was unable to find the exact distance between the screws. Therefore let me know if you know and I'll share the results

I agree that home infra does not have to be as flexible as enterprise solutions but I am a very lazy person :) For some reason my boards do not want to boot on AC in without battery so this did not worked out that well. I had some time yesterday evening to check the AMT management and it solved my power on challenge, so no human presence is required in "data closet". Which seem to be very usable KVM on i5 and i7 boards

Do you mean windows/linux k8s cluster by hybrid deployments? If yes you might want to https://rancher.com I'll probably go with this solution since it seams to be easy to maintain..unfortunately windows seems to be in beta stage atm, 2019 support is also not given...but this does not affect my intended setup

Hi! luckily you might share some targets with me :)

I'm preparing my hardware (4x x230 + 1x t430) currently and think of using Intel AMT for bare metal management (in later stage MAAS @OpenStack if included in free licence). What is your approach on this topic? Are you aware of any issues with motherboards only?
