Every Pixel Has Its Own Microcontroller Imagine a display where every single pixel has its own brain. That's the ambitious idea creator bitluni set out to bring to life in a six-month engineering project. Instead of relying on a central GPU, the display turns every pixel into an independent computing node. The ultimate goal is a 65,536-core QVGA display, while the first working prototype already features 8,192 RISC-V… |

DIY Flight Tracker Using ESP32 This should be the easiest and cheapest way to build a flight tracker system. Maker from the Youtube Channel - Tech Talkies recently built this incredible DIY flight radar that runs entirely on an ESP32-S3 Zero, a round GC9A01 display and a rotary encoder. All the parts assembled onto a custom made 3D printed enclosure. Instead of capturing radio waves locally, it… |

Autonomous Robotic Fish Combines Computer Vision and Wireless Charging A YouTube channel named CPSDrone has developed a fully autonomous robotic fish capable of operating without direct human control. The project, which took nearly three months to design and build, demonstrates how bio-inspired robotics can replicate the movement and behavior of aquatic life while integrating advanced robotic capabilities. Unlike traditional remote-… |

ESP32-P4 Powers a DIY IP KVM for Remote PC Control Remote access devices like IP KVMs are usually built around powerful single-board computers such as the Raspberry Pi. But what if the same job could be handled by a microcontroller instead? That's what creator Jonathan Rowny set out to explore by building a functional IP KVM using Espressif's ESP32-P4. The project aimed to remotely stream a computer's display… |

This DIY Pick-and-Place Machine Delivers 10-Micron Precision Assembling tiny SMD components by hand is one of the most challenging parts of PCB manufacturing. Some components, especially 0201-sized parts, are so small that accurately placing them with tweezers can quickly become a tedious and error-prone task. That's why factories rely on highly automated pick-and-place machines that can cost thousands, or even millions, of… |

Two-Way Holographic Display with Wemos D1 Mini This display can show two different images at the same time - no VR headsets, no software tricks, just pure optics. This is a two-way holographic display made by Julius Makes. The whole idea is that two players, sitting opposite to each other, should see the mystery instructions meant for the other person. Plus, they should be able to see their faces through the… |

FIFA World Cup 2026’s Trionda Ball Has a 500Hz Sensor Inside With the 2026 FIFA World Cup now under way across Canada, Mexico and the USA, adidas' official match ball, Trionda, is in use at all 104 matches of the tournament. Beyond the colour scheme tied to the three host nations, the ball's more interesting story for engineers is the sensor package built into it. Trionda uses the latest version of adidas' Connected Ball Technology, built around… |
