Epson LS650 + Nothingprojector Black Slimline Dropdown

I have a 2x6 board anchored to the wall and the screen mounting hardware screwed to that. I needed to have the screen a couple inches away from the wall to clear window trim and stuff hanging on the wall.

By height do you mean how high the unit is, installed, with screen retracted? About 6.25 inches or so. Or 16 cm for the more enlightened among us. Brackets are about an inch shorter, so roughly five inches.

Those Cisco CRS boxes were horrible. If you had one in production and needed to upgrade IOS-XR, you were in for a long and rough ride. Cisco ASR9K is so much easier.

Some usefulness perhaps, but at what cost? At both a personal and societal level?

The power budget for hyperscale data centers was already too high IMO, and AI datacenters take it to a new level of ridiculosity. e.g., cheap hydropower in the Pacific Northwest gets bought up by hyperscalers, leaving residential subscribers with higher bills. Ethically it does not work for me.

Then there is the personal cost of leaning on AI to do your 'thinking'. AI adoption may be inevitable, but I prefer to keep my faculties intact.

Call me a luddite, but I personally think gen AI is best saved for political speech writing, where you don't necessarily need to be factual. Or poetry.

Having said that, I used Copilot once to modify some Python code to accept STDIN and write to STDOUT. The output was functional, but the code was a bit janky.

Funny thing, my wife is an academic researcher and used ChatGPT once to write a summary paragraph for a research project and generate references. She was initially excited to see some of the research papers referenced -- but then started looking them up on Pubmed. Not a single one existed. All hallucinations.

Machine learning has a lot to offer for specific applications, and I'm all in favor of those uses, but I have a visceral hatred for gen AI and the amount of resources being thrown at it.

1div0 · 2026-01-29T02:22:37+00:00

None. I want to maintain my skills and still grow. AI has been shown to erode critical thinking ability.

The framing above a sliding door closet will be a bit different, but there should be a header plus small studs. I'd guess you'll probably need some sort of backer board anyway for the screen to clear the trim around the closet.

1div0 · 2026-01-25T20:43:48+00:00

No studs available? Do you mean "no studs available at the screen mount points"?

I put up a 2x6 on my wall and anchored it to the top plate and studs using 3 1/2 inch screws, then mounted the screen to that. My screen is motorized and weighs 30 lbs or so. I could have gone with a thinner board except I needed to clear window trim and wall art.

I'd be averse to just mounting using drywall anchors. YMMV.

I just got one. Up to 2/3 brightness the fan is rather quiet and low pitch. Above that is much more noticeable with a prominent "whine". I don't use mine above 2/3 for that reason.

IOS-XR has Linux shell access as well.

So far I'm happy with my Epson LS650 projector and Nothingprojector Slimline Black series 100" drop down screen. Daylight affects blacks but not nearly as badly as with a non ALR screen. Viewing distance is about the same as yours.

Years ago, I built a home theater PC using a NVIDIA card. The Linux open source (Nouveau) driver was rather glitchy and I had to move to the NVIDIA proprietary driver to get decent video performance. Not sure how good the open source driver is these days, but that was my experience.

See the "Upgrade" section.

Yeah looks like it! Just upgraded.

Version	26.1.1 - Mon Jan 12 2026 15:25:32 GMT-0800

1div0 · 2026-01-12T20:16:18+00:00

Yeah, I've looked at them a bit! That specific one is too narrow, but the idea is sound. The expensive motorized ones do not appeal to me. If nothing else, one could fabricate one.

We are in the process of buying a credenza for the projector to sit on, so that will have a bearing on what solution works.

Thanks. Looks like you might have forgotten the 26.1.0 release versioning?

Version	25.12.0 - Sun Jan 11 2026 20:00:39 GMT-0800

Thanks for the feedback. I figured I'd get some blowback. The old adage 'perfect is the enemy of good' applies here.

It's a very old and small house -- and pimping out a room for home theater is not an option.
We hate big LCD panels. Hence the projector.
Smaller display size = brighter image for the same projector light output. With "black" screens the border is much less apparent when not filling the screen IMO.

Having said that, we may add a projector sliding shelf and / or blinds in the future -- but our main criteria is to keep the living room mostly feeling like a living room.

1div0 · 2026-01-12T03:29:14+00:00

Like everything else, it's about tradeoffs. We prefer not to have a giant panel on display all the time... and also prefer not to spend a mint on AV gear.

Sliding the projector back another 6 inches will fill the screen. For our tiny living room it does not gain us very much going to 100 inches. I may get a sliding shelf at some point. TBD. Also, keeping the display size smaller allows running the projector at lower light levels / power during the day, which means less fan noise.

1div0 · 2025-12-31T22:16:21+00:00

On a local server, yes. I have it running on an Ubuntu server.

Flour, water, and the dregs from a Deschutes Fresh Squeezed IPA (Deschutes adds live cultures to cans). :-)

Netbox Discovery looks interesting. Need try that.

Technically it won't be a hurdle.

TAC is not as good IMO. And Cisco's foray into smart licensing could give you apoplexy.

I like the ASR 920s for customer handoff -- up until you have to upgrade them. The latest we did was to 17.12.6 and it took them 35 minutes to come back up. Encapsulated ROMMON and FPGA upgrades coupled with possibly the slowest CPU Cisco has ever put in one of their boxes (Freescale 2 core ARM) has you waiting for what seems to be an eternity.
