Stavros Korokithakis built a custom e-ink terminal using a Raspberry Pi Zero W, a Pimoroni Inky Impression 7.7" display, and a custom 3D-printed case. Motivated by a desire for a distraction-free writing environment and inspired by the now-defunct TRMNL project, he documented the entire process, from assembling the hardware and designing the case to setting up the software and optimizing power consumption. The result is a portable, low-power e-ink terminal ideal for focused writing and coding.
The Evertop is a DIY open-source project aiming to create a modern, portable, and extremely low-power IBM XT compatible computer. It features a 4.2" e-ink display, mechanical keyboard, and boasts over 100 hours of battery life. Based on a Raspberry Pi Pico microcontroller emulating an NEC V20 processor, it can run original IBM XT software and DOS games. The project includes custom-designed PCBs and 3D-printed case files, making it reproducible for others. While still under development, the Evertop represents a unique blend of retro computing and modern hardware for a highly portable and energy-efficient experience.
Hacker News commenters generally expressed enthusiasm for the Evertop project, praising its unique combination of retro computing and modern e-ink technology. Several highlighted the impressive battery life and the appeal of a distraction-free writing device. Some questioned the practicality given the slow refresh rate of e-ink, particularly for gaming, while others suggested improvements like backlighting and a more ergonomic keyboard. A few commenters expressed interest in similar projects using different retro hardware, such as the Apple II or Commodore 64. There was also discussion about the challenges of sourcing parts and the potential market for such a niche device. Several users shared their personal experiences with similar e-ink projects and offered technical insights.
Security researchers at Prizm Labs discovered a critical zero-click remote code execution (RCE) vulnerability in the SuperNote Nomad e-ink tablet. Exploiting a flaw in the device's update mechanism, an attacker could remotely execute arbitrary code with root privileges by sending a specially crafted OTA update notification via a malicious Wi-Fi access point. The attack requires no user interaction, making it particularly dangerous. The vulnerability stemmed from insufficient validation of update packages, allowing malicious firmware to be installed. Prizm Labs responsibly disclosed the vulnerability to SuperNote, who promptly released a patch. This vulnerability highlights the importance of robust security measures even in seemingly simple devices like e-readers.
Hacker News commenters generally praised the research and write-up for its clarity and depth. Several expressed concern about the Supernote's security posture, especially given its marketing towards privacy-conscious users. Some questioned the practicality of the exploit given its reliance on connecting to a malicious Wi-Fi network, but others pointed out the potential for rogue access points or compromised legitimate networks. A few users discussed the inherent difficulties in securing embedded devices and the trade-offs between functionality and security. The exploit's dependence on a user-initiated firmware update process was also highlighted, suggesting a slightly reduced risk compared to a fully automatic exploit. Some commenters shared their experiences with Supernote's customer support and device management, while others debated the overall significance of the vulnerability in the context of real-world threats.
Ghostwriter is a project that transforms the reMarkable 2 tablet into an interface for interacting with large language models (LLMs). It leverages the tablet's natural handwriting capabilities to send handwritten prompts to an LLM and displays the generated text response directly on the e-ink screen. Essentially, it allows users to write naturally and receive LLM-generated text, all within the distraction-free environment of the reMarkable 2. The project is open-source and allows for customization, including choosing the LLM and adjusting various settings.
HN commenters generally expressed excitement about Ghostwriter, particularly its potential for integrating handwritten input with LLMs. Several users pointed out the limitations of existing tablet-based coding solutions and saw Ghostwriter as a promising alternative. Some questioned the practicality of handwriting code extensively, while others emphasized its usefulness for diagrams, note-taking, and mathematical formulas, especially when combined with LLM capabilities. The discussion touched upon the desire for similar functionality with other tablets like the iPad and speculated on potential applications in education and creative fields. A few commenters expressed interest in the open-source nature of the project and its potential for customization.
TCL is betting on "NXTPAPER" screen technology, which aims to mimic the look and feel of paper for a more comfortable reading experience. This technology utilizes multiple layers of reflective material to enhance contrast and reduce blue light, creating a display that appears brighter in sunlight than typical LCDs while maintaining low power consumption. While not e-ink, NXTPAPER 2.0 boasts improved color gamut and refresh rates, making it suitable for not just e-readers, but also tablets and potentially laptops. TCL aims to expand this technology across its product lines, offering a paper-like alternative to traditional screens.
Hacker News commenters discuss TCL's NxtPaper display technology, generally expressing skepticism about its widespread adoption. Some doubt the claimed power savings, especially given the backlight required for color displays. Others question the "paper-like" feel and wonder if it truly offers advantages over existing e-ink or LCD technologies for typical use cases. A few commenters express interest, particularly for niche applications like e-readers or note-taking, but overall the sentiment is cautious, awaiting real-world reviews and comparisons to determine if the technology lives up to its promises. Some also discuss the history of similar display technologies and their ultimate lack of success.
