Key Takeaways
1. A Reddit user created a dual-screen e-reader that folds in half, featuring two e-paper displays for a more book-like experience.
2. The e-reader uses an ESP32S-3 chip and has two 5.83-inch e-paper screens, along with dual 1,300 mAh batteries for extended use.
3. It boasts low energy consumption, allowing the device to last over a month on a single charge due to its efficient components.
4. The design includes an SD card slot, physical navigation buttons, and a USB-C port, while being sleek and protective without a case.
5. The software is still basic, relying on custom code for ePUB parsing, text rendering, and the user interface.
E-reader makers frequently say that their E Ink screens are the ideal substitute for traditional paper books. Yet, one major distinction between e-readers and real books is that the screen merely replicates a single “page.” This can sometimes give off a vibe similar to reading a brochure instead of an actual book.
Innovative Design
Luckily, an individual has devised a unique idea for a dual-screen e-reader that folds in half, showcasing two e-paper screens when opened. This brilliant idea comes from a Reddit user known as Spacerower, who began looking for solutions after he broke the screen on his older e-reader.
Not finding an e-reader that met all his needs, he decided to create one on his own. This led to the development of the dual-screen e-reader. It features an ESP32S-3 chip and includes two 5.83-inch e-paper displays. Moreover, there are two 1,300 mAh batteries included, so it’s not just the screens that come in pairs.
Power Efficiency
E-paper displays are recognized for their very low energy consumption. When you pair this with the efficient ESP32-S3 chip and its 7 µA deep sleep mode, the device can last over a month on a single charge without any issues.
Additionally, the e-reader comes equipped with an SD card slot for saving books and other materials, some physical buttons for navigation and page turning, and a USB-C port for charging. The device is relatively sleek, with each side measuring just 8 mm thick. When closed, it measures 16 mm. A significant advantage of this dual-screen design is that the displays are protected, meaning it doesn’t require a case for safeguarding.
Software Limitations
However, there are some drawbacks regarding the software. The maker confesses in the Reddit discussion that the software is still quite basic. Currently, the e-reader uses custom code for ePUB parsing, text rendering, and the user interface.
