It's a 5.2 inch Android Ereader. I purchased this and received it today. I bought both this and a Kindle Basic. The Kindle ended being more comfortable device to use for my hand size. I used it for a total of three hours. I have already performed the english process detailed here. Some more information about this device can also be found here or on the r/InkPalm5 Subreddit.

Last time I looked, this was the best guide for converting to English that isn't just ripping off everyone else's work: https://github.com/philips/inkpalm-5-adb-english

The original one had my curious when I first started looking for a pocket e-Reader. I had no idea they existed at all. The idea just appeared to me one day when I got out of the shower and I left my phone with a news article that had a white background on the screen. I thought "man that looks like eInk at this angle, that would be cool if that device existed" and sure enough it did. I saw the github to convert most of it to english https://github.com/philips/inkpalm-5-adb-english but I ended up getting the HiSense Touch instead right before this updated version came out.

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
