Edge AI Wildlife Detection Using Raspberry Pi Zero and Smart Camera Luke Ditria has created a tinier and less expensive version of a wildlife-monitoring device that he built earlier. The tool makes use of AI to detect animals in real time, without needing the internet. The original version’s use of a Raspberry Pi 5 and Hailo AI accelerator led to its increased price. This compact version uses a Raspberry Pi Zero 2 W and a smart camera that has AI built into it… |

iRonCub3 Jet-Powered Humanoid Robot Achieves First Stable Flight A jet-powered humanoid robot named iRonCub3 just took its first flight. This robot, developed by the Italian Institute of Technology (IIT) in Genoa, lifted about 50 cm (1.5 feet) off the ground while maintaining stability. It has four engines, two on the arms and two on a jetpack on its back. This development follows years of research and testing that include real-world flight tests and… |

BITS Hyderabad Develops ₹15 Biosensor for Needle-Free Health Testing Researchers have reportedly created a low-cost biosensor at Birla Institute of Technology and Science (BITS), Hyderabad campus. Their biosensor is said to cost only ₹15 to make. What it offers is a way to detect health markers without needles, bypassing traditional blood tests. In a span of five minutes, it can detect chemical compounds called metabolites from blood, sweat, urine, and cells.… |

China’s Microdrone Innovation Brings Stealth at the Smallest Scale China’s National University of Defence Technology (NUDT) created a mosquito-sized drone, roughly 1.3 centimeters long, tailored for stealth tasks like intelligence gathering for the military. The tiny size makes for easy camouflage in any environment, allowing it to remain close to invisible in covert missions. The drone has insect-like wings that flap to mimic natural movement. … |

Paralyzed Patient Uses Elon Musk’s Neuralink Chip to Play Games Using Thoughts Rob Grenier became paralyzed after a car accident in 2022. He very recently received a Neuralink brain implant in June 2025 and shared this captivating experience on X, calling it “absolutely amazing”. He was able to move a cursor and play video games using only mental commands. The technology fundamentally is a small implantable chip that’s designed to form a direct communication path… |

This Salamander Robot Got a New Spine and Smarter Gait YouTuber soiboi soft upgraded his robot modelled after a salamander. The project is bio-inspired, copying designs and behaviors from the amphibian. The robot uses soft actuators and rolling diaphragms, making it flexible and allowing for clean and natural movements. The diaphragm pumps and solenoid valves controlled by an Arduino make up the electrofluidic system. The legs are inspired… |

MIT Combines GaN and Silicon Chips for Faster, Efficient Electronics Researchers from MIT and elsewhere have developed a new way to combine two types of chips: gallium nitride (GaN) and silicon-based CMOS chips into a single chip. The solution is cheaper, scalable, and more energy-efficient. Gallium nitride chips are not cheap or easy to work with, but they are faster and better at handling power. Silicon chips, on the other hand, are cheap and common but lack… |

Inside the DIY Robot That Rolls Like a Drone on the Floor Max Imagination has published the making of a DIY spherical robot that moves by rolling inside a transparent plastic ball. It’s meant to entertain pets, explore tight spaces, and be driven via smartphone, like an FPV drone that rolls on the floor. The project uses an XIAO ESP32S3 Sense from Seeed Studio, which includes Wi-Fi, a 2MP camera, a mic, and a microSD slot. Two geared motors… |

This Transformer Robot Was Built to Be Ridden, Not Just Looked At A maker built a real-life transformer robot that switches from a car to a robot, just like in the movies. The build is designed for someone to ride, much like a toy car. The robot uses Gimson Robotics 99.5:1 gearhead motors with additional 3D-printed two-stage gear reductions. Six motor assemblies power all leg joints. It uses AS5047 magnetic encoders to track joint positions, allowing… |

DUAWLFIN, A Drone That Can Both Fly and Drive Using the Same Motors Researchers from UC Berkeley have developed a unique hybrid drone that both flies like a quadcopter and drives on the ground using the same motors. Unlike the average drone that needs separate motors or propellers to move on the ground, DUAWLFIN uses a clever mechanical system called a differential drivetrain to switch between flight and wheels. The spinning of propellers is not required while… |

SlimeVR Butterfly Trackers for VR, Motion Capture, and Much More SlimeVR has introduced its new wireless full-body tracking solution based on the success and experience of previous versions. It improves comfort, adds battery life, and is lighter. Each tracker in the system contains an IMU sensor that wirelessly sends data to your PC or smartphone. The SlimeVR Server software uses the data in relation to your body’s proportions and headset position to… |

DIY Piano Doorbell That Replaces the Classic Chime with Musical Notes A simple piano doorbell that replaces the usual chime with real piano notes was demonstrated in a recent project published by Arpan Mondal. The system combines microcontroller-based control with audio playback to create an interactive doorbell. At its core is an ESP32-S3, which takes inputs from 5 keys styled like a tiny piano. Each key is built using micro limit switches and connected… |
