After some conversation with @freakazoid - I'm back to contemplating what my personal technology stack should look like.

One thing that I keep coming back to is screens.

I use the omnibook because it has great battery life on AA batteries. It has great battery life on AA batteries in large part thanks to it's monochrome, reflective, non-backlit screen.

If I could get a screen like that on a cybredeck, I'd be set.

@ajroach42 @freakazoid

Have you looked much into eink? I *really* want a general purpose eink display.

@enkiv2 @freakazoid Yeah, there just aren't any decent general purpose eink displays.

I have a hisense a5. It works reasonably well.

@ajroach42 @freakazoid

Yeah, I was expecting to have to wire something up tbh

@ajroach42 @freakazoid I wish the Sharp 800x600 6ish" memory LCD looked better than it did (although some of the problem may be the resistive touch panel on my Sharp e-notepad) - the smaller memory LCDs blow the OmniBook's screen out of the water.

@bhtooefr @freakazoid I'd honestly go for something like that if I could find it, but they don't exist for sale as far as I can tell.

@enkiv2 @ajroach42 Waveshare has a 10.3" e-ink display with an HDMI input.

@ajroach42 @freakazoid And the e-notepad they were designed for was replaced with an e-ink model...

@bhtooefr @ajroach42 The Sharp memory displays are my favorite display so far. Like e-ink in terms of contrast and power consumption, but with a much faster refresh and simpler interface.

@freakazoid @enkiv2 I was just looking at that! $500 still isn't great, but it's manageable.

@ajroach42 @freakazoid
$500 is expensive. I was thinking buy a used kindle off ebay and disassemble it tbh.

@enkiv2 @ajroach42 @freakazoid if you don't mind a lower resolution and coming up with your own display pipeline over SPI, this one is significantly cheaper at $170 for 9.7" 1200x825:

@djsundog @enkiv2 @freakazoid Where did this come from? I swear there were no eink screens over 4" available for the pi a year ago.

@djsundog @enkiv2 @freakazoid If someone hacks together a display driver, this would be a great option.

@ajroach42 @enkiv2 @freakazoid if you told me waveshare just displayed a random selection of available e-ink screens on any given web page load I would not act surprised tbh

@ajroach42 @enkiv2 @freakazoid it looks like @martijnbraam has an open source driver for the controller on that e-ink display that allows for pushing display data over the usb port...

@djsundog @ajroach42 @enkiv2 @freakazoid

It _should_ work with that driver, it's still not super great to work with since it requires root access to control it. You do get a lot of control over the panel though you won't get with HDMI.

@ajroach42 @enkiv2 @freakazoid

should also take a look at this python project, which apparently supports this board as well (theoretically, anyway) via SPI:

@ajroach42 @djsundog @enkiv2 @freakazoid
This is something I've wished for for years now. Have a look at this project for waveshare displays. You can get a terminal, display images or configure a full desktop via connecting to a vnc server on the same system. I have used the terminal portion on my 2.13" epaper display.

@ajroach42 @djsundog @enkiv2 @freakazoid
Now I kind of want to setup that terminal dashboard I've been playing with on eink.

@kelbot @ajroach42 @djsundog @enkiv2 @freakazoid

You could also go with

that's on my short list for a picture frame if i ever get the time/space to build one

@kemonine @djsundog @ajroach42 @kelbot @enkiv2 I don't see a datasheet for it but I'm guessing the power draw is too high for Andrew's application, since it looks like a standard backlit display.

@martijnbraam @djsundog @ajroach42 @enkiv2 The driver boards for those displays are as big as a full-size Pi. Any chance one could drive such a display directly via GPIO pins or something?

@freakazoid @djsundog @ajroach42 @enkiv2 not easily, that driver chip does a lot of analog magic. the board can probably be smaller if you made your own PCB with the IT8951 to fit your formfactor. would also save you from the annoying adapter board for the e-paper panel


@ajroach42 @freakazoid Another idea:

They’re apparently who has the rights to manufacture Pixel Qi LCDs, and they claim to have 7” panels in stock…

@bhtooefr @freakazoid 706 area code? That's GA mountains.
