📟 Labfab's Open-Source CO2 Sensor
The sensor would help you to determine the periods of ventilation in closed spaces, in particular in the school context. Indeed, a high concentration of CO2 in a classroom has the possible consequence of a drop in concentration and even a state of drowsiness. The CO2 sensor is designed to interpret these different CO2 alert levels by simple color code.

💻 Consistent Error Handling in C++
Error handling in firmware is a difficult task. If you decide to ignore errors, the best you can expect is a deadlock, but you could also damage the hardware.
When reviewing existing code, you can often find boolean return values or a system of error codes. The problem with these systems is the lack of readability. It is hard to say whether true is the result of a successful call or means an error.
In the article, author explains different methods to handle errors in your firmware. Although the provided examples are for the Arduino Uno, the concepts will work with any platform and with all modern C++ compilers.

🎬 ESP-NOW - a new protocol for Wi-Fi data transfer between ESP32 or ESP8266 ESP-NOW is a protocol ideally suited to sending out small amounts of data (up to 250 characters). In this video, author uses ESP32 as receiver and an ESP8266 as transmitter and demonstrates…
📟 ESP-NOW: Auto-pairing for ESP32/ESP8266 with Bidirectional Communication and Web Server
This guide shows how to build an ESP32 web server and use ESP-NOW communication protocol simultaneously. We’ll show you how to establish a two-way communication between the master (web server) and slaves, and how to automatically add boards to the network (auto-pairing).

Mini Pupper is open-source, based on Ubuntu and ROS (Robot Operating System), and designed for robotics education in schools, homeschool families, enthusiasts and others, with notably students being able to learn out to use ROS, SLAM, navigation, and OpenCV computer vision through online courses that will come with the robot.
One fully assembled and configured, the dog-shaped quadruped robot that can hop, trot, and run around, finding its way around using SLAM, Navigation, and OpenCV AI functions. Mini Pupper’s software relies on a fork of ROS based Champ Quadrupedal Framework led by Juan Miguel Jimeno, which you can also find on Github. ROS2 support is also in the works.

📟 hgDeck - a wrist-word desk with a hybrid interface
The design for this project is based on earlier hgTerm Raspberry Pi mini-laptop, which honestly would have made a great entry all by itself. But while the two version shares some similarities, the hgDeck puts a serious twist on the form factor.
Device is based on the Raspberry Pi Zero W Soc. It contains one main 3.5" SPI TFT screen and additional 1" OLED screen. Additionally, it has BT keyboard, pi camera and MLX90640 thermal camera. The casing is 3D printed on Prusa Mini. It has a motor and a linkage system which enables it to (semi) automatically switch between just the display mode and full terminal (display+keyboard) mode.

📰 Tentacle robot can gently grasp fragile objects
Most of today’s robotic grippers rely on embedded sensors, complex feedback loops, or advanced machine learning algorithms, combined with the skill of the operator, to grasp fragile or irregularly shaped objects. But researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated an easier way.
Taking inspiration from nature, they designed a new type of soft, robotic gripper that uses a collection of thin tentacles to entangle and ensnare objects, similar to how jellyfish collect stunned prey.
The researchers used simulations and experiments to test the efficacy of the gripper, picking up a range of objects, including various houseplants and toys. The gripper could be used in real-world applications to grasp soft fruits and vegetables for agricultural production and distribution, delicate tissue in medical settings, even irregularly shaped objects in warehouses, such as glassware.

📟 TinyML-CAM pipeline enables 80 FPS image recognition on ESP32 using just 1 KB RAM
The challenge with TinyML is to extract the maximum performance/efficiency at the lowest footprint for AI workloads on microcontroller-class hardware. The TinyML-CAM pipeline, developed by a team of machine learning researchers in Europe, demonstrates what’s possible to achieve on relatively low-end hardware with a camera.
Most specifically, they managed to reach over 80 FPS image recognition on the sub-$10 ESP32-CAM board with the open-source TinyML-CAM pipeline taking just about 1KB of RAM. It should work on other MCU boards with a camera, and training does not seem complex since we are told it takes around 30 minutes to implement a customized task.
