Air Lab ESP32-S3 air quality monitor

Networked Artifacts’ Air Lab is a portable air quality monitor based on ESP32-S3 Wi-Fi & Bluetooth LE wireless SoC, equipped with an e-paper touchscreen display, and plenty of sensors to measure CO2, temperature, relative humidity, air pollutants (VOC, NOx), and atmospheric pressure. The Air Lab ships with a rechargeable 1,500 mAh battery that will be good for about 21 days on a charge in passive mode (taking measurements every minute), and you can also power it over its USB-C ports. It includes a debug port for people wanting to change the firmware, and a GPIO header to connect additional sensors if required. Data can be visualized on the e-paper display or transmitted over BLE or MQTT for integration with Home Assistant. The company also provides a CSV export function and a web-based dashboard for data visualization. Air Lab specifications: Main module – ESP32-S3 module with PCB antenna for 2.4GHz WiFi […]

ANAVI Miracle Emitter – A WiFi and BLE RGB LED controller compatible with Home Assistant, WLED firmware (Crowdfunding)

ESP32-C3 RGB LED Strip Controller

ANAVI Miracle Emitter is an open-source hardware ESP32-C3 WiFi and BLE controller designed to control 5V addressable RGB LED strips, which works with Home Assistant over MQTT and also supports the popular WLED firmware to easily control the LED strip through a web interface. It also features four I2C expansion headers for sensors and a small OLED display, a UART header, and a GPIO header. It’s an update to Leon ANAVI’s Miracle Controller introduced in 2019 with an ESP8266.

Battery-powered Seeed Studio IoT Button features ESP32-C6 SoC, supports ESPHome or Zigbee firmware

Seeed Studio ESP32-C6 IoT Button

Seeed Studio IoT Button is an inexpensive ESP32-C6 button powered by a rechargeable 18650 battery and designed to easily and quickly control Smart Home devices over WiFi 6 or Zigbee wireless protocol. It will be especially handy to Home Assistant users since the device is pre-flashed with ESPHome firmware for easy integration (over WiFi), and the company also provides a Zigbee firmware for Zigbee Home Assistant  (ZHA) integration. The hardware is pretty basic with a button, three LEDs, and a USB-C port for charging the replaceable 18650 battery.

Matter compatible. USB – […]

PiEEG kit – A Raspberry Pi 5-based bioscience lab in a suitcase (Crowdfunding)

PIEEG Kit Bioscience Lab Raspberry Pi 5

Yesterday we wrote about using quantum sensors for brain-computer interfaces (BCI) and other biomedical applications. But that’s the future, and if you want to experiment with brain-computer interface technology and bioscience, the PiEEG kit has everything you need to get started, with all components fitting in a suitcase easy to carry around between your home and university or school. The bioscience home lab is based on the PIEEG Shield for Raspberry Pi introduced in 2023, and features a Raspberry Pi 5 8GB, a 9-inch display, a sensor board, EEG electrodes and cables for brainwave measurement, and electrodes for EMG (muscles), EKG (heart), and EOG (eye) signal recording. The PiEEG kit is comprised of the two main custom boards with the following specifications/features: PiEEG Shield on top of the Raspberry Pi 5 ADC – Texas Instruments ADS1299 Analog-to-Digital Converter for biopotential measurements Host interface – 40-pin GPIO header with SPI protocol […]

Huginn is a self-hosted, open-source alternative to IFTTT and Zapier

Huginn open source automation tool

IFTTT and Zapier automation tools enable users to create automated workflows connecting various apps, services, and devices. They are relatively easy to use, but their free tiers are now rather limited, and you have to rely on the cloud. Huginn is a self-hosted, open-source alternative to IFTTT or Zapier that can work on your own network without cloud connectivity. Andrew Cantino released the first version of the project 12 years ago (in 2013) by Andrew Cantino, but it now has a larger community of developers and users. Somehow, I only found out about Huginn when XDA Developers wrote about it earlier this week. Let’s have a look. Developers describe Huginn as a system for building agents that perform automated tasks for you online, and view it as a hackable version of IFTTT or Zapier hosted on the user’s server with full control over the data. Here are some of the […]

Radxa Orion O6 Preview – Part 2: Debian 12 – What works, what doesn’t

Orion O6 Review Debian 12

I went through an unboxing and Debian 12 installation on the Radxa Orion O6 at the end of January, but decided to work on other reviews since software support still needed to be worked on. Since then, there’s been some work done, but no new image released. After waiting for almost two months, I’ve decided to carry on with the review by testing the Debian 12 image in a way similar to the Rock 5B SBC preview I did with Debian 11 in 2022 to check what works and what doesn’t on the Orion O6 at the time of the review. That will involve testing all ports, including 5GbE networking and the PCIe slot with an (old) NVIDIA graphics card, running some benchmarks, and also trying the Debian 12 image with a self-built Linux 6.13 kernel using ACPI instead of UEFI for the default image. Orion O6 SBC benchmarks on […]
