Have you seen the "Open Book" project?

If you want to get all custom, you could build an e-reader https://github.com/joeycastillo/The-Open-Book https://www.tomshardware.com/news/raspberry-pi-pico-powered-open-source-ebook-reader

>I really wish I could have an e-reader, but again, I don't want to spend money on things that will lock me into a single vendor indefinitely and might just arbitrarily go away.

This may be up your alley.

It's not a commercial off the shelf product, but the Open Book uses a 4.2" screen. There are other devices you can find on places like AliBaba that are kinda small. However, in general you won't find a name brand commercial ereader under 6" that isn't ina phone body. There were a couple at 5" back-when but the industry really settled on 6" as the common base size.

This is very useful to see examples of how people have used APIs that are either poorly documented or not at all. Or even that are well documented, really. Going from docs to code is not always straightforward.

To give you just one example, recently I've been using it to find how people have written code to interface with e-ink displays. I usually have the datasheet which lists all the commands the protocol support, but building it all into a valid startup sequence of ~20 commands to activate the display is left as an exercise for the reader.

So the docs will look like this: https://www.waveshare.com/w/upload/6/6a/4.2inch-e-paper-spec...

And what I need is a sequence like this: https://github.com/joeycastillo/The-Open-Book/blob/5c5054c58...

There is a link to the project early in the article: https://github.com/joeycastillo/The-Open-Book

Hi Rust experts, we are willing to integrate rustix on NuttX RTOS, the initial effort was done by rustix author: https://github.com/bytecodealliance/rustix/tree/nuttx but it hit the wall since we don't know the right way to integrate cargo with the old-school NuttX's Makefiles. Any help or suggestion is welcome. More about NuttX here: https://nuttx.apache.org and here: https://nuttx.apache.org/docs/latest/

Open Source Autopilot for Drone Developers PX4 is an advanced and open source autopilot flight stack for drones. PX4 can flight completely autonomously for pre-programmed missions, or, obviously, it can help a pilot who remote-controls the drone. It runs on NuttX RTOS.

You should definitely have a look at NuttX.

Maybe Nuttx can be an alternative. Have a look: https://nuttx.apache.org/

Zephyr, RIOT, NuttX are all open source RTOSes happy about contributions

Microcontrollers are a good start. Boards are cheap and sensors are plentiful. You could get a yet unsupported board and port RIOT, Zephyr or NuttX.
