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.

They are very reflective; a light from near the camera could look like that, but could be seen as a misleading choice.

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.

Sounds like a battery, or maybe even a dishwasher.

I see some kind of illumination from below/behind the display. Being from Gamers Nexus, I'd be shocked if it was manipulated. Maybe just a really steep sidelite

They have a money printer that gives them nearly unlimited flexibility. Being a private company means Gabe can do long-term investments without concern. Steam has been an incredibly good steward of its position, but I fear for the day when capitalism finally sinks its claws into the platform.

> capitalism finally sinks its claws 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.

I think they know it'll hurt goodwill. I think they don't think they have to care what other people think about them. I think they think they're too big to fail.

If we can’t extract all the value, no one can.

But unironically lol. Eventually there will be a snap back. But probably not our generation

I think that depends on what generation you're in. Because that generation is definitely here now and pissed off at the manipulative enshittification.

The real magic is the esp32, it talks to the steam box with Bluetooth. A Linux app sends metrics to the esp32 and it refreshes the display.

Why would you use esp32/bluetooth though and not just SPI/i2c directly?

It seems like one of the design goals was separation/independence. It also doesn't need a battery if it is meant to be tightly coupled with the Steam Machine. Which is nice for opening it up to many alternate uses.

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.

Yep. And I will mentor them

Care to fix this ungrammatical headline? :)

I think this site is from the UK where companies are plural (they are made of people after all). Is there some other grammatical issue you have... it is kind of meandering, but that's taste more than grammar. What would you suggest instead?

To me it reads like a demand: "Valve, open source the Steam Machine e-ink screen"

If we are talking past tense, "Valve have open-sourced.."

And if we are talking American "English," then "Valve has open-sourced..."
