image-gallery VS epd-waveshare

Two:

Both of these require rendering the content via an HTTP endpoint and both of these currently still require the content to be proxied through the device backend.

> I can buy an ESP32 e-ink screen and run esphome or any of several other open source projects and put a piece of wood on the front of it, too.

Yes, you can! And if you do this, you have absolutely no need to use my e-paper smart screen.

I am hoping to add third party apps, that's why I have created the API for 3rd party apps:

https://github.com/Invisible-Computers/image-gallery/blob/ma...

But right now, I understand that building an app for my platform is

a) more hassle than just pointing to a URL

b) limited upside, because the audience that you can charge for a subscription isn't very big yet.

However, I think that a good app could generate its own audience (aka drive ppl to buy the displays) and then make money by charging them a small monthly subscription fee.

I'll ship within Europe as soon as I have bootstrapped the 7000 Euro necessary for CE certification.

In terms of openness, there is this:

and this:

I also want to make the esp32 controller itself more hackable in future, but I don't want to promise anything because that's quite a lot of work for me.

Here is the API description:

And here is the sample app:

Admittedly, I am not the greatest technical writer, but I compensate by being pretty responsive. :)

This display offers a simple API to build applications for it:

https://github.com/Invisible-Computers/image-gallery/blob/ma...

The API doesn't require any special knowledge about e-paper displays, it just expects an image URL in the correct resolution and will then render it to the display.

You can buy the display off the shelf, and if you are interested in building an app, contact me at [email protected] for a developer account :)

Feel free to go to town on it :)

I ported epd-waveshare V2 to async Rust, ran the sample on battery power using a 3.3V LDO. I did it in Partial Refresh mode. During this, display border appeared along with all that noise.

If anyone wants to make a similar project, there is a great Rust API to most of the Waveshare displays[0] (I added support for the display mentioned in the article 5in65f).

I also made a project[1] with it that generates art using a gameboy emulator and some static images and other transforms to show on the display.
