What I really want is an A3 e-ink display that is designed to have a pdf loaded onto it, then can be disconnected and taken around a machine shop. No WiFi or Bluetooth etc

You'll pay out the nose on that. From what I understand, the larger the e-ink screen is the harder it is to manufacture. Which is why small tablet ones reign supreme, and larger monitor sized ones are shockingly expensive, somebody else here has already linked to a 25 inch display for $1800

How long will the display last like this?

I've been using an eInk screen for over 12 years - it is refreshed multiple times per day. It is as crisp and clear as the day I got it. Admittedly, I'm not trying to run video on it constantly and it doesn't get hot. But eInk seems remarkably durable.

That's probably, what, 200,000 refreshes?

From what I gather, at book-reading speeds, newer e-ink displays may never wear out in a human lifetime.

But at usable computer display speeds I rather suspect many of these panels have a lifetime one might measure in months.

I've been using this solution for about 4 days now. It's not meant to be used as your main monitor. I use it only when I want to read something I or someone else has written. I think it's also good for simple writing too. But if I try to use it as my main monitor, browsing the web, writing code, etc. it will become a real headache because of the latency. One huge plus is that it isn't *just a monitor*. because of the…

How is the latency for drawing? I am going to start doing this, but it makes me think, it would be nice to have a way to disable full refresh while drawing, and doing tablet-side drawing over the current VNC frame while the stream is paused, and asynchronously forwarding the input which will hopefully recreate the same drawing path on the server.

I don't know how to do what you are describing, but right now, the drawing is OK. it's not instantaneous but good enough for me, not creating artworks. just doodles and scribbles. I just don't look at the tablet screen for drawing. I only use it as an input because the refresh rate is low for this. but the VNC latency itself is not annoying (I would guesstimate ~0.2s), although I think there are ways to make VNC latency less.

There are directly ekink monitors now. Dasung 13k color is workable-ish even on MacOS with no tweaks.

Well this is no replacement for them! The monitors you mention are from 700$ (Dasung 13k is 750USD currently) up to 2000USD. This is an old tablet you maybe have lying around or can get for 200USD maybe?

And this is more than a monitor. the VNC provides you with an interface. you can use your tablet as the input device. and it's also portable.

Ooh, crowdsupply looks interesting. This is my first time seeing it.

CrowdSupply is great - I ran a successful project through them. And I would definitely recommend anyone doing some hardware taking a look. There are a couple of things to be aware of - everything is shipped to the US and then distributed from there (using Mouser US). From the project point of view this means, depending on where things are manufactured) tariffs can come into play. The terms of shipping to mouser are d…

This was a really interesting read! Back in the day a friend and I started a company and Kickstartered a RPi add-on. The kickstarter campaign failed, but we ended up building anyway after one of the silicon manufacturers spotted the project and provided some FoC devices which changed the economics.

We spent oodles of time on it, learned lots, build a fairly simple product but ended up selling it through some of the bigger RPi retailers. It was all an excellent learning experience, and ignoring our time we made about 50p out of the entire batch of a thousand. Factor in our time and it was a complete financial disaster, but we were young and carefree and had fun doing it!

Dasung 253 is a 25.3 inch eink display. https://shop.dasung.com/products/dasung-25-3-e-ink-monitor-p... I bought it two years ago for over $1800, and I have to say, it was worth every single dollar. I can read on it, work on it, (kind of) watch youtube videos on it, play (some) RTS game on it. And mine only had 33hz refresh rate, not the latest 60hz.

I couldn’t make it work on macOS (I.e Mac Studio 2).

What problems did you run into?

The latency for drawing on the Boox Note Max is excellent. Best on the market or close to it.
