Debashis Das writes that the ZecTrix Note 4 is an ESP32-S3 based smart note featuring a 4.2-inch e-paper display and integrated voice capabilities for managing reminders, weather, and schedules. The device offers both monochrome and four-color variants (Note 4C) and includes built-in hardware such as a microphone, speaker, NFC, and a rechargeable battery.
- Uses Espressif ESP32-S3 SoC with vector extensions for machine learning workloads.
- Features community firmware options like Slate or TransitInk OS to repurpose the device.
- The Note 4C four-color variant is notably cheaper than the monochrome version on the manufacturer's website.

Researchers at Los Alamos National Laboratory have successfully addressed long-standing gaps in Erwin Schrödinger's century-old theory of color perception. By employing advanced geometric methods, the team provided a mathematical framework for how humans experience hue, saturation, and lightness as intrinsic properties of a color metric rather than learned experiences. A major breakthrough included defining the neutral axis through geometry and utilizing shortest-path calculations in non-Riemannian space to explain complex perceptual effects like the Bezold-Brücke effect. This work has significant implications for visualization science, including photography, video technology, and scientific imaging.
Pimoroni has released new Inky Impression color E Ink displays for Raspberry Pi in 4.0", 7.3", and 13.3" sizes featuring Spectra 6® technology. These low-power, high-resolution screens are designed for easy assembly without soldering and include features like rear-mounted buttons and Qwiic/Stemma QT connectors.
MDColor is a Python script designed for Linux terminals that takes Markdown text via piped input and outputs a colorized and styled version directly to your terminal. It enhances readability by applying ANSI escape codes for bold, italic, headers, code blocks (with syntax highlighting via Pygments for supported languages), lists, links, and more.
Amazon has launched the Kindle Colorsoft Signature Edition, the first color version of its e-reader. The device features E Ink's Kaleido technology, is priced at $279.99, and is set to ship starting October 30th.
