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… |

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… |
