This ESP32-C6 Wall Frame Turns a 1993 Arcade Board Into a Fake AI That Answers Yes or No Reddit maker MrShatanas found four large old circuit boards in a garage and decided they were too good-looking to throw away. One of them is now a piece of sci-fi wall art: a 3D-printed frame packed with lights, a slow-motion fan and a pointer that answers YES or NO to your questions. A single Waveshare ESP32-C6 board with a built-in 1.47 inch LCD runs the whole thing. … |

Getting Started with M5Stack Tab5: ESP32-P4 Touchscreen Development Board Large touchscreen development boards are useful when a project needs more than a microcontroller and a few expansion pins. A display, camera, audio system, wireless connectivity, storage and industrial interfaces can turn the development board itself into the starting point for a complete embedded product. The M5Stack Tab5 takes this approach with a 5-inch 1280 × 720… |

Getting Started with the PUI Audio AMP2X15 Audio Amplifier Board and Speakers Adding a speaker to an embedded project is not always as simple as connecting it directly to a microcontroller or single-board computer. Most audio sources provide a relatively low-level signal, while a speaker needs more power to produce useful sound output. This is where an audio amplifier becomes important. The PUI Audio AMP2X15 is designed to bridge this gap,… |

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… |
