• Review of CM4 XGO Lite – A Raspberry Pi CM4 based smart robot dog with a robotic arm

  The CM4 XGO Lite is a smart robot dog based on Raspberry Pi CM4 system-on-module and designed to learn to program using Blockly, Python, and ROS. This four-legged robot also happens to feature a 3-joint robot arm and a robot gripper installed on the back that can pick up light objects. The Raspberry Pi CM4 module drives the LCD screen and camera and performs AI and computer vision processing, while each joint is controlled with a servo motor, and a 6-axis tilt sensor ensures stable walking and movement.

• Open Source Rover Gets An Update For Easier Building

  Once upon a time, NASA-JPL put out a design for an open-source rocker-bogie rover. It was an impressive and capable thing, albeit a little expensive and difficult to build. Now, the open source community has dived in and refreshed the design, making it cheaper and more accessible than ever before.

• Multi-Year Doorbell Project

  Camera modules for the Raspberry Pi became available shortly after its release in the early ’10s. Since then there has been about a decade of projects eschewing traditional USB webcams in favor of this more affordable, versatile option. Despite the amount of time available there are still some hurdles to overcome, and [Esser50k] has some supporting software to drive a smart doorbell which helps to solve some of them.

• The Fossil Wrist PDA becomes a tiny Gopher client (with Overbite Palm 0.3)

  It turns out there's a reason for that, and we're going to patch the operating system so we can make the Fossil Wrist PDA into what may be the smallest (and first wrist-mounted) Gopher client. That also required an update to the Overbite Palm Gopher client (which you'll want for your 68K Palm anyway), and then there's the matter of the battery refusing to charge as well. And finally, we want to make all of this portable!

  But let's start with the history first ...

• Lab-on-a-drone detects and analyzes pollutants from the sky

  Air quality concerns encompass several different pollutants and irritants. Chlorofluorocarbons (CFCs) were, for example, a major concern in the 20th century due to the damage they cause to the ozone layer. But not all pollutants are easy to monitor. Hydrogen sulfide, which causes irritation of the eyes, nose, and throat at low levels and much more serious symptoms at high levels, can collect in pockets. To find them, researchers from Brazil have a developed a low-cost lab-on-a-drone.

• Raspberry Pi Pico Air Quality Monitor Integrates Telegram

  There are three main aspects of air quality that the sensor is able to register. The sensor reports total volatile organic compounds (TVOC), equivalent CO2 (eCO2), and air quality index (AQI). According to Karabudak, the idea behind this project was to both monitor the air quality and raise awareness about air quality in general and how it impacts public health.
