The world of devices that incorporate e-ink screens is diverse and still poorly understood. There are typewriters, reading glasses, advertising panels, and full-format monitors. In this review there are several representatives of this world and not a single E-Ink reader.
Shelf labels
Why bother with paper price labels in supermarkets when you can replace them with electronic shelf labels, the information on which is updated instantly? That's what the largest US retailer Walmart thought and planned to equip 2,300 of its shops with ESL by 2026.
iPhone case
Reinkstone sells cases for the iPhone, from version 13 onwards, that have a colour e-ink screen built into them. I immediately thought of a use for this screen: I could display the cover of the ebook I'm reading. This would remove one of the disadvantages of ebooks: no matter what you read on your smartphone, it's not easy to tell your friends, colleagues and random travellers on the transport. I'm willing to bet that this is one important motivation for paper book buyers, though they'll never admit it. They say you can also find such covers for Android smartphones on AliExpress.
Something like iPod
Playing music can probably even irons already, not to mention the fact that we all have a few devices that can do the job. The ePiPod is an iPod-like device for those nostalgic for standalone players. The e-ink screen makes the device lighter and cheaper. If you just want to listen to music, this minimalist screen will be enough to navigate your music catalogue. But it's not that simple: this project is for those who want to build the gadget themselves, adapt the Python code and upload mp3 files to the device the good old fashioned way without any streaming.
