• Welcome home! An original Astro Pi computer back from space is now on display at the Science Museum

  After seven successful years on the International Space Station, 250 vertical miles above our planet, the original two Astro Pi computers that we sent to the ISS to help young people run their code in space have been returned to Earth.

• Intelligently control an HVAC system using the Arduino Nicla Vision

  Suryo developed his proof of concept as a 1:50 scale model of a plausible office space, complete with four separate rooms and a plethora of human figurines. Employing Edge Impulse and a smartphone, 79 images were captured and had bounding boxes drawn around each person for use in a FOMO-based object detection model. After training, Suryo deployed the OpenMV firmware onto an Arduino Nicla Vision board and was able to view detections in real-time.

• Raspberry Pi Project Detects and Recognizes Bird Calls

  BirdNET-Pi is a tool designed to run on the Raspberry Pi that uses TFLite to process audio input and listen to bird calls. It was put together by Patrick McGuire, who forked the project from Stefan Kah’s BirdNET-Lite. BirdNET-Pi is optimized for the Raspberry Pi and can run on the Raspberry Pi 4B, Raspberry Pi 400, Raspberry Pi 3B, and even the Raspberry Pi Zero 2 W.

  The system works by listening to bird calls using a USB microphone. The audio input is parsed through BirdNET-Pi and processed to identify what bird was likely making the sound. According to the GitHub page, BirdNET-Pi can identify hundreds of birds from different countries around the world.
