What's really nice about tiny e-readers is that you can read without having to move your eyes horizontally.
If there are only four words per line, you can slide your eyes down the middle and take in all the words in a chunk like you would for normal speed-reading.
I have an xteink X4 and X3 and I swear I can read for much longer without strain. You can also just crank your margins way up on most other e-readers.
Is it really worth the tradeoffs of having significantly smaller storage space, reduced screen size, and clicking through way more often, just to not have to move your eyes as much horizontally?
I agree but I adjust text like this for readability using epubs and iPhone apps. I don’t see a reason for another device given how good iPhone screens are now.
My current e-reader is an Openbook Abridged designed by Joey Castillo of Oddly Specific Objects. It is larger than this tiny device, but smaller than something like a smartphone, and I think it is the PERFECT size. It's a similar kind of device which actually has even less features than this O24. I love it so much, and have been reading so much more than I used to since I soldered the kit together ~6 months ago.
"Since the ESP32 only supports 8MB of onboard storage" - an SD card breakout with SPI interface costs 2 bucks. That would be an easy addition. I think there are also ESP32 boards with SD card slot but this would also make for a nice custom PCB.
I'm not that fond of eInk, having tried a PocketBook Verse e-reader (more open than a Kindle, has a microSD slot for my 70+GB fully DRM-free eBook collection) with a fairly grainy screen.
A recent article on HN convinced me to try the M5Stack Paper S3. Much nicer screen with 16-level grayscale touchscreen, microSD slot, ESP32-S3 with WiFi and Bluetooth, supports the Crosspoint Reader software. It's got a magnetic back but won't fit on the back of a Magsafe phone like the Xteink4 can. It's double the price, but well worth it.
I feel like this article was made for me specifically because I have a handful of Waveshare ePaper HATs for the Pi Zero that are currently sitting unused, they have standard GPIO connections in addition to the HAT interface that I should use along with an ESP32, because battery life would be much more important than running a full linux install for this!
