Inkplate 6 MOTION STM32-powered wireless e-paper display offers higher resolution and faster refresh rates (Crowdfunding)

The Inkplate 6 MOTION is a new product from Soldered Electronics in their Inkplate series of wireless e-paper displays. It is a 6-inch e-paper display with a partial refresh rate of 11fps which reduces obvious latency in rendering dynamic content such as videos, animations, and scrolling text. The display is driven by an STMicroelectronics dual-core STM32H743 microcontroller, with an ESP32-C3 as a secondary processor. It features Wi-Fi and Bluetooth for networking and a host of peripheral interfaces for physical connectivity. It includes several sensors such as a rotary encoder for quick navigation, a gravitational accelerometer with a gyroscope for tracking device orientation, and a motion detection sensor. We covered the original Inkplate 6 display when it launched on Crowd Supply in 2019. The Inkplate 6 is much less expensive than the new model but has a lower screen resolution (800 x 600 px) and slower refresh rates (256ms). Furthermore, it […]

BreadboardOS firmware for the Raspberry Pi RP2040 features a Linux-like terminal

Cavin McKinley’s BreadboardOS is an open-source firmware platform for the Raspberry Pi RP2040 MCU (for now) built around FreeRTOS and with a feature-packed CLI that reminds me of the Linux terminal.

The terminal implementation is based on a fork of the microshell project with some additional customization. It is organized into POSIX-style folders/files providing a familiar user interface for interacting with the hardware on the MCU.

BreadboardOS running on Raspberry Pi Pico board

BreadboardOS highlights:

FreeRTOS-based
Tools for checking system resources such as ps, top, free, and df commands
Interaction with chip I/O and serial buses from the terminal using commands such as cat and echo, for example, you can print the list of GPIOs with:

Compact ESP32-S3 based air quality sensor uses an LED dial to tell how clean your air is (Crowdfunding)

If you are curious about the air quality in your area, then Studio LUFF Air Quality Sensor might be just the thing for you. It is designed to be affordable, open-source, portable, and customizable. Studio LUFF is a design practice based in California, United States composed of Pierluigi Dalla Rosa and two others. Collectively, they “advocate for an alternative approach to technology that is driven by curiosity, creativity, community and sustainability.” The Air Quality Sensor is their first product. The Air Quality Sensor is powered by an ESP32-S3 microcontroller and uses a Plantower PMS7003 particulate matter sensor module to measure air quality. It looks like a small, black disk with AQI (air quality index) values that run from 0 to 200. An LED dial is mounted on the back of the device which reflects on the wall to display the current air quality index in the area. The project was inspired […]

/e/OS v2 privacy-focused, Google-free Android mobile OS released with improved UI, Android Auto support, etc..

The e Foundation has just announced the release of the /e/OS v2 Android-based Google-free open-source mobile operating system with an improved launcher, support for Android Auto, a “Wall of Shame” to identify the most leaking apps and tracker, QR Code scanning support in the camera app, and more. Most Android smartphones come with Google services which may be convenient (and help keep Android free), but come at the loss of the users’ privacy. That’s why the e Foundation started offering e/OS over five years ago to offer a privacy-focused version of Android without Google services on specific phones. The project has evolved over the years, over 200 mobile devices are supported officially and unofficially, and Murena, a for-profit company, has also been established to sell e/OS smartphones and cloud services. /e/OS v2 highlights and changes: Based on LineageOS 20 with the latest bug fixes and security updates (itself based on […]
