How to Build a Smart ESP32 Noise Pollution Monitoring System with IoT Urban areas are now affected by acoustic disturbances; major Indian cities such as Mumbai, Kolkata, and Delhi rank among the noisiest in the world, driven by dense traffic, construction, festivals, and industrial activity. Extended exposure to these noise levels leads to health issues, including disturbed sleep, increased stress, cardiovascular risk, hearing damage,… |

ESP32-CAM AI Vision Assistant Pendant for the Visually Impaired Moving through unfamiliar environments is a challenging thing for visually impaired people. We have a lot of solutions, from sticks to obstacle-avoidance handheld devices on the market, to solve their problem. In the DIY world, a lot of makers have built obstacle-avoidance sticks using Ultrasonic sensors, IR sensors or even a PIR sensor and different variations of… |

He Gave His Open-Source Robot Pixel a Gemini-Powered Brain That Perceives Depth Without a 3D Sensor Naz Louis has upgraded his open-source robot Pixel, giving the walking desk robot a new AI system that can see, remember, and reason about its surroundings in real time. The new build runs on Gemini Robotics ER2, an embodied-reasoning model built by Google DeepMind for near real-time robotics applications. The model receives a continuous stream of camera and microphone input and has direct… |

Cat Collar Fits Two AI Models' Runtime Memory Into 48KB of Its 256KB RAM by Never Running Them Together An open source project called Meowtion packs two on device AI models onto a single microcontroller with only 256KB of RAM, using a scheduling trick rather than model compression to make it fit. Built by Jerome Graves and documented on Hackaday.io, the wearable collar tracks a cat's eating, drinking, and resting behaviour to flag early changes that can precede illness. The collar runs on… |

How to Build an AI-based Air Quality Monitoring using ESP32 Air is a necessity for us human beings, so monitoring it is important. Air quality is monitored in terms of the Air Quality Index(AQI), a single-number scale used to tell how polluted the air is and what health effects it might cause. Particulate Matter is the microscopic solid or liquid which is present in air in the form of dust or smoke. Particulate Matter is the… |

Someone Turned 4 Trashed Laptops Into a Private ChatGPT That Got Faster With One Laptop Removed Maker Joe C-J has repurposed four discarded Lenovo ThinkPad L380 laptops into a working, self-hosted AI computing cluster, capable of running large language models entirely offline. Each of the four motherboards was stripped from its laptop chassis and mounted into a custom 3D-printed frame, designed in Fusion and reprinted to accommodate a fourth node after an earlier three-node version… |

ESP32-S3 Runs a 28.9-Million-Parameter LLM, Borrowing a Memory Trick From Google's Gemma Developer slvDev has published an open-source project that runs a 28.9-million-parameter language model directly on an ESP32-S3, a microcontroller that costs roughly $8. The model runs entirely on the chip itself, with no data sent to a server, generating text at roughly 9 tokens per second and outputting it to a small connected display. The achievement stands out because of how little working… |

Quaddle Is an Open-Source Desk Robot That Can Move Omnidirectionally With Just 4 Servos Petoi, the team behind the open-source Bittle and Nybble quadruped kits, has opened early access for its next robot, Quaddle. The company describes it as a four-servo quadruped capable of walking, strafing sideways, and spinning in place, a claim that stands out mainly because of how few actuators it uses to pull it off.
Most legged robots that can… |

How to Build an IoT Indoor Weather Station Using CircuitDigest Cloud "Is it going to rain, or should I leave the windows open?" we would have asked ourselves numerous times. Now the weather is clear, but sometimes the rain will suddenly start pouring. The standard weather forecast application may give you accurate forecasts near the airport or other places, which are kilometres away from us, but it will not give us accurate forecasts… |

US Slams the Door on Chinese Humanoid Robots Over National Security and Backdoor Risks The Federal Communications Commission added humanoid robots, quadruped robots, and networked power inverters to its Covered List on July 28, 2026, blocking new equipment authorizations for these device categories going forward. The move effectively halts new imports of foreign-made robots that mimic human or animal movement, along with grid-connected inverters used to link solar panels,… |

Andhra Pradesh Launches Twin AI Centres to Give DeepTech Startups GPU Power and Mentorship Andhra Pradesh has set up two new AI-focused facilities, one in Amaravati and one in Visakhapatnam, which began operating on July 28. The initiative comes with backing from the central government's electronics and IT ministry, working alongside the state's own IT and electronics department. Both sites will run under the… |
