Ultra-Low-Power Neuromorphic Chip Enables Always-On Voice Detection A new neuromorphic chip has shown it can perform continuous voice activity detection while using extremely low power, addressing a major challenge in devices that rely on batteries or operate at the edge of a network. The chip identifies human speech with very fast response times by running neural network calculations in the analog domain. This method keeps voice detection running without… |

World’s Smallest Programmable Micro-Robots Open a New Frontier in Robotics Researchers from the University of Pennsylvania and the University of Michigan have unveiled the world’s smallest fully programmable autonomous robots. Measuring just 0.2 × 0.3 × 0.05 mm, these microscopic swimming robots are barely visible to the naked eye yet can independently sense their environment, process information, and perform programmed tasks. Each robot integrates sensing,… |

ESP32 Meets On-Device AI: The ESP Private Agents Platform Espressif introduces the ESP32-based AI voice assistant with on-device processing by the ESP32 Private Agents Platform. It helps developers and students to build customizable AI assistants for the ESP32. The traditional way, which is the embedded AI assistant, requires stitching together multiple complex components such as cloud backends, device firmware, and speech recognition. ESP32… |

How MIT's Aerial Microrobots Fly as Agilely as Insects Engineers from MIT have developed aerial microrobots that are roughly 450% faster with about 250% better acceleration in comparison to prior demos. “We want to be able to use these robots in scenarios that more traditional quadcopter robots would have trouble flying into, but that insects could navigate,” said Kevin Chen, an associate professor at MIT. The robot's controller is… |

Custom Quad-Rotor Drone Hitting 605 km/h Sets Unofficial World Record The Drone Pro Hub team recorded their drone reaching a top speed of 605 km/h. The feat was the outcome of an 18-month effort headed by FPV specialist Benjamin Biggs. The quad-rotor drone, mounted on a base for take-off, featured onboard GPS telemetry that allowed speed monitoring. While not recognized as an official record, they tested the right way and calculated the average speed of… |

ESP32-Based AI Fridge Magnet Takes Your Handwritten Shopping List Maker Jack Of All Tech built a fridge magnet powered by AI that could read a handwritten note to update the shopping list on a smartphone. The idea was to have a device on his refrigerator that would let him write stuff, get it recognized using AI, and send that information to a phone using an API call. The maker sifted through various hardware options before finally settling on a 2.8”… |

DIY Underwater Jetpack: Shark vs 100 kg of Thrust Makers at the YouTube channel CPSdrone took on the challenge of trying to outswim a hungry shark. They pictured getting on the Aquadart 770 Extreme, which is supposed to go at a maximum speed of 25 km/h and saw themselves becoming lunch. On a mission to outperform this underwater sea scooter, they started with thrust testing motors in a water tank in their workshop. They tried the… |

HackStar, A USB Ethical Hacking Tool Capable of HID Emulation Remotely Creator Hathey Mash has launched a Kickstarter campaign for HackStar, described as an advanced ethical hacking tool. It is capable of acting like a USB HID device, meaning it can send keystrokes (mimicking human patterns) and also control the mouse. Through languages including Python, C, C++, and MicroPython, one can program it to execute custom scripts, including payloads for automated… |

XPENG’s Next-Gen IRON Humanoid Needed to Prove It Wasn’t Human XPENG’s latest iteration of IRON was showcased at XPENG’s AI Day on the 5th of November 2025. It’s made quite an impression with its catwalk, impressing some viewers and causing suspicion among others. It reached a level of anthropomorphism where people were genuinely confused if it was an actual humanoid or if there was a human inside a synthetic outfit doing the walking. The online buzz was… |

wafer.space, Silicon Fabrication Made Accessible Through Pooling Acquiring custom chips usually means dealing with complex negotiations and a large minimum order requirement. wafer.space is a pooled fabrication solution to that. You submit your design through an automated system and, in return, get 1000 identical bare dies or chip-on-board (COB) assemblies (each bonded to a small PCB). The area to design your chip is standard, a slot measuring 3.88 mm × 5.… |
