Bilingual E-paper News Feed Helps Brush Up Language Skills

[Bob] recently completed LanguageLearner, a desktop device that increases his exposure to a second language by offering up bite-sized news items in Italian, with a complementary English translation. Even better, it’s a project made almost entirely from inexpensive parts he had on hand; it consists of little more than a Raspberry Pi Pico W, a 4.2″ E-paper display, and a 3D-printed stand.

Here’s how it works: once every few hours, the system wakes up and uses its WiFi connection to fetch news from an Italian RSS feed. Having chosen a slice of current events, it translates to English with an API call then displays both versions on the display: original Italian up top, translated English below.

Consisting of little more than a Raspberry Pi Pico W, an E-paper display, and a 3D-printed stand, it’s a great use of spare parts.

E-paper is ideal for a semi-passive project like this because once data is written to the display, there it remains without needing power or upkeep of any kind. Perfect for a device that only wakes up every few hours for an update before going right back to sleep.

Due to the limited RAM of the Raspberry Pi Pico [Bob] has to be purposeful about fetching data, so he relies on text from a simple RSS feed to avoid running out of memory while making web requests. The other minor quibble is that the driver for the display only handles plain ASCII; characters that cannot be rendered are displayed as grey boxes, which you can see in the image up top. Still, it gets the job done.

Increasing exposure to a language one is learning is beneficial, and people like to experiment. From trying to optimize human wait times by inserting language micro-lessons to a calculator that works in Toki Pona, technology offers new ways for folks to experiment with how we learn and play with language.

RSS Printer Gives You The Hard Copy News You Desire

The days of yore saw telex machines and dot-matrix printers with continuous feed paper churning out data in hardcopy form in offices around the world. [Jan Derogee] wanted a bit of that old-school charm, and set about building a RSS news printer using a venerable old printer in his possession. 

The build relies on an ESP8266, with the WiFi-enabled microcontroller readily capable of jumping online and querying RSS feeds for content. It scrapes the XML files for title, description, and publication date information, and formats this for output to the printer. The microcontroller then spits out the data over a Commodore serial interface to a Brother HR-5C printer. Unlike dot-matrix printers of its contemporary era, the HR-5C is a thermal printer. Once loaded up with a roll of the appropriate paper, it can print continuously without requiring any hard-to-source ink ribbons.

Armed with a continuous supply of wireless internet and 210 mm rolls of thermal printer paper, [Jan]’s system should provide news summaries to him for years to come. We’ve seen similar retro news ticker projects before, too. Video after the break.
