I wish more hardware companies treated these kinds of optional add-ons as something the community can run with instead of either productizing them badly or locking them away completely...

In case you're wondering and don't want to click around, the display is a standard Adafruit 5.83'' eInk panel: https://www.adafruit.com/product/6397

I wonder how they achieve the lighting effect from the banner picture? It doesn't look like the Adafruit panel has backlighting built-in, and there isn't anything added in the project.

Anyone know what the refresh rate for these displays are, at least with the stock firmware? Reading the datasheets didn't help, though maybe I didn't know what to look for.

The refresh rate of eink is kind of...muddy. It depends on temperature and target contrast. With the right waveform and voltage, you can push it pretty far(like 30hz+).

The thing is, Eink's waveform is kind of secret afaik, everyone has different tuning.

As I understand it going faster typically skips steps that are necessary for maintenance of the panel. Fine for a while but if you don't periodically run a "proper" cycle the panel could eventually be permanently damaged.

That's exactly it. I was a firmware engineer at reMarkable making the latest tablets.

We had some secret eink sauce (propriety waveforms) to get the high refresh rates and colour contrast without a full flashing screen reset, but even then you need to run longer maintenance refreshes occasionally.

Pixels are just vertical columns of viscous fluid with charged ink particles. A waveform is just voltage changes over time to these columns to shift the particles up and down. More black to the top = darker shade of grey. Colour (in the gallery display, at least) is the same, just with each CMY particle group having different charges and responses to different waveforms.

Every once in awhile this vertical column gets messy with loose particles distributed through it (ghosting, muddy contrast) so performing a hard rail-to-rail voltage reset forces all the particles up and then down, and gives you a clean slate.

Out of interest, what (vaguely) is the amount of time you need between maintenance refreshes?
reply

It really depends on the state of the screen. It's easier with reading PDFs, for instance, when you can get away with a full refresh on page turns.

Versus someone drawing on the screen with a lot of zooming and panning. People with the tablet would notice that when they stop a series of these actions that were back to back, the screen will "clean" itself after about 5 seconds of idleness.

It's not that those steps are necessary to prevent damage, it's that those steps were traditionally necessary to maintain calibration of the individual cell states. Also...the first several generations used really slow graphics processors based on the premise that use cases didn't require fast refreshing.

eInk mostly fixed the calibration issue years ago before the first eink monitors came out, and most eink products these days use beefier graphics processors.

Data sheet seems to say (Page 8 -https://cdn-shop.adafruit.com/product-files/6397/P6397+C2226...):

Same, but the front is important for airflow in the Framework Desktop, so I don't think covering it with an e-ink screen would work. But maybe with some space between the screen and the fan intake?
reply

Yeah, it might need some kind of a riser to prevent airflow restriction. Of course, I suppose it depends on how many squares you cover.

The other idea I keep noodling about is creating modular gears and perhaps using a servo for a really cool dial indicator instead, but alas, it hasn't made it further than my ideas bin.

This is so cool! Coincidentally, I'm currently building something in a similar vein that pushes system metrics out to an Android app so an old phone or tablet can be used as a case screen. The app has widget plugins that expose a repo of metrics received and a GL surface, that can then be used to display fancy visualisations.

Check it out here: https://github.com/xfoa/humours. It's not finished yet, but the basic functionality works. It just has one widget at the moment that draws a spinning cube with temps, etc.

I would love to see an analysis of how valve's openness and goodwill affects their bottom line. Intuitively it should be a net positive for them, but there gotta be upfront costs, otherwise everyone would be doing it too.

1. Valve is a private company with a money printer (steam) 2. the point of these initiatives is to build an ecosystem with steam at the centre.

A better way to look at this is valve is trying to hedge it's self against microsoft. By creating an ecosystem of devices and software that's full open so they're not reliant on Microsoft. The goal of Valve hardware ISN'T to make money. It's to encourage others to build devices free of Microsoft that Steam can be installed on.

They have nothing to gain by being closed, and everything to gain by being open.

Capitalism has nothing to do with short term greed.

Some CEOs are just too arrogant and think that optimizing for the short term won't hurt goodwill. That's their own failure. Capitalism says nothing about how a business should be run. It's merely defining the idea that humans who own things (capital) allocate their resources and keep the result.

That's an interesting case of a display being off actually indicating something ("loss of power") which can't be replicated with a bistable screen.

On the other hand, you probably don't want that glow of an active screen all the time. Status LEDs are annoying enough.

My kindles usually show a dead battery graphic when I get back to them after a long time away... With enough power storage and the right trigger, this could be done.

"Valve will not be making and providing their own e-ink display for the Steam Machine"

Too bad. The picture in the articles looks awesome. Like a device from some alternate reality. Neither retro nor the standard flat-panel LCD.

I don't want to mod a pre-build $1,049 device. I want it to be good our of the box and I'd rather pay more to get more. (If it was a $3K top-of-midrange machine, I would buy it in a second.)

You're not modding a pre-built $1049 device. The faceplates are removable and swappable with no disassembly needed, and this fancy one connects via bluetooth and is powered via a battery. Entirely non-invasive.

Gamers Nexus did a very in depth review of the Steam Machine [1], which includes a comparison to a build yourself similar machine.

The result is that for about 70 dollars less you can put together a somewhat more powerful PC than the Steam Machine, but not for that form factor, it would still be bigger.

IMO, the Steam Machine is not a bad purchase if you are in the market for that type of product.

You can't build a machine which is as powerful, small, quiet, and cheap, nor can you take for granted that a machine you build can have a controller that can wake it from sleep, or which has HDMI-CEC (both are possible, but take extra work or hardware). You can rather easily build a machine with multiple of those attributes, but you'll have to pick ones to sacrifice in the name of the others.

The Steam Deck itself doesn't have an HDMI port, but the official dock does, and that does support HDMI-CEC (support was added to SteamOS a couple years ago). The Steam Deck also does support controller wake from sleep (added in the past year or so); I've actually seen people complaining about their Steam Decks waking up when they didn't realize that feature existed.

And all of the reviews I've seen about the Steam Machine talk about how well both of those features work.

It does not. Source: have a dock. Latest firmware installed from deck. And because the current Steam controller is a recent release, I had to try a whole mess of third party controllers before settling on PS5 controllers because everything else I tried had Bluetooth pairing issues / disconnects as you approached four controllers.

SteamDeck as a handheld is great plus or minus a few nits baked onto the power / battery life choices Valve made. SteamDeck -> TV and SteamDeck -> USB-C KVM are both workable, with caveats. I had hoped we would see the bug fixes you describe before the Steam Machine release. Alas, no.

CEC support was added in to the Dock in May 2024 https://store.steampowered.com/news/app/1675200?emclan=10358...

Bluetooth wake made available for LCD Decks in September 2025 (it was already available in OLED models) https://store.steampowered.com/news/app/1675200/view/4983336...

I will say that the Deck has less than stellar bluetooth reception in my experience too. I settled on an 8bitdo controller because my XBox Elite couldn't stay connected from across the room. The Steam Machine has a dedicated antenna for Steam Controllers though.

You are confidently incorrect.

SteamDeck supports HDMI-CEC as of 3.7 ~2 years ago, using the original dock or select third party docks.

---

How to Enable CEC:

Press the STEAM button and go to Settings.

Navigate to the Display tab.

On the right side of the screen, find and toggle on Enable HDMI CEC Support.

Ensure Wake TV when device resumes from sleep is also enabled.

The only thing you might lose by building your own and running SteamOS is HDMI-CEC.

The steam controller would work just fine.

For a small gaming box it is a good price.

If you don’t care that much about size, HDMI-CEC or SteamOS there are faster alternatives for the price.

Especially since, afaik, you plug it in and it just works. No messing around with installing operating systems, setting up users (aside from signing into steam) or anything. It's essentially a console that plays PC games, but it's also a PC for the purposes of upgradability and ability to do other, non-console stuff with it
