A hobbyist’s bilingual e-paper news feed uses a Raspberry Pi Pico W, a 4.2-inch e-paper display, and an RSS source in Italian—showing each story in the original language with an English translation below, updating only every few hours.
A device sits quietly for hours, then wakes just long enough to pull in something worth reading.
For Bob, the goal isn’t another gadget that begs for constant attention. It’s a small. semi-passive language study tool built from parts he already had on hand: a Raspberry Pi Pico W. a 4.2″ e-paper display. and a 3D-printed stand. When it runs. it fetches short news items in Italian. translates them into English. and shows both versions on the screen—Italian on top. English below.
The routine is simple. Once every few hours, the system wakes up over its WiFi connection and fetches news from an Italian RSS feed. After it picks a slice of current events. it sends the content to an API call to translate it into English. Then the display refreshes with both the original text and the translation. After the update, the device goes back to sleep.
E-paper is central to how quietly it works. Once data is written to the display. it remains there without needing power or ongoing upkeep—exactly what you want for something that wakes up. does its task. and shuts down again. The whole build is described as “almost entirely” made from inexpensive. spare components. with the finished setup consisting of little more than the Pico W. the e-paper screen. and the stand.
There are practical limits, too, and Bob has to work within them. The Raspberry Pi Pico’s limited RAM means he has to be careful about what it fetches and how it requests content. so he relies on text from a simple RSS feed to avoid running out of memory while making web requests. Another constraint is the display driver: it only handles plain ASCII. Characters the display can’t render show up as grey boxes.
Even with those quirks, the project lands where it matters—regular exposure. Increasing exposure to a second language one is learning is described as beneficial. and the build is framed as an invitation to experiment. The same theme shows up in other examples mentioned alongside it: people trying to optimize human wait times by inserting language micro-lessons. or building a calculator that works in Toki Pona.
In the end, the device doesn’t try to replace study. It does something more modest and more repeatable: it turns spare parts into a steady stream of bilingual reading, with no maintenance cycle beyond the next update.

So it’s basically a news app that only updates every few hours? Kinda sounds pointless but also I want one.
“Almost entirely” spare parts… that’s just code for it probably glitches all the time. Also the grey boxes thing means it can’t even show Italian right half the time.
Wait, the Raspberry Pi Pico W wakes up to pull RSS and then shuts off?? I thought e-paper still needs constant power. Not sure why this translation part matters either, couldn’t you just Google Translate when you want it?
This is cool I guess, but why is he doing news in Italian instead of like… actual learning? If you’re only seeing stories every few hours your brain won’t retain anything. Also ASCII only?? Italian has accents, so wouldn’t that break half the point? Still, I like the idea of a screen that sits there quietly, wish my phone was like that.
