ESP32-S3 Runs a 1998 PlayStation Game With Game Files Loaded From a MicroSD Card on Demand David Montero Crespo, creator of Velxio.dev, has managed to run the classic 1998 PlayStation game Metal Gear Solid on the tiny, low-cost microcontroller board - the Seeed Studio XIAO ESP32S3 Sense. Instead of emulating the old PlayStation hardware, the project rebuilds the game from its reversed C source code and compiles it directly to run on the ESP32-S3’s processor. The game data is stored… |

ESP32-S3-Based Compass Uses a 3-Axis Magnetometer for Real-Time heading and Direction Readouts LazyDays Creation built a compact, portable digital compass based on an ESP32-S3 Super Mini and a three-axis magnetometer. He chooses an ESP32-S3 Super Mini because it is capable enough for the project while also including a built-in lithium-battery charging circuit. A round colour display gives the finished device a distinctive watch-like appearance, while the rechargeable battery allows it… |

This STM32 Turns 3,000 Mechanical Pixels Into a Real-Time Fluid Simulator With Joystick-Controlled Gravity Maker Tim Alex Jacobs has turned nearly 3,000 old electromechanical flip dots into an unusual real-time fluid simulation display. Instead of using an LCD or LED panel, the project uses eight salvaged flip-dot panels, where every pixel is a small magnetic disk that physically flips between two positions. which is black and yellow. The result is a display that not only shows the movement of the… |

A Tiny Robot Hides Inside a 3.5-mm Poker Chip to Cheat at Roulette With 433 MHz Radio and a Custom PCB Kevin Coda of Concept Bytes Youtube channel built a tiny remote-controlled robot inside a poker chip for Mark Rober's CrunchLabs casino challenge. The project turns a standard poker chip into a miniature mobile robot that can move across a roulette table after receiving a wireless command. To make room for the electronics, the chip was hollowed out using CNC machining and its internal steel… |

This ESP32-Powered Self-Balancing Cube Jumps With a Spring and Uses a Reaction Wheel to Land on Its Edge A maker from The Tinkering Techie has done a compact self-balancing cube that can launch itself into the air, reorient during the jump, and land upright on one of its edges. Unlike conventional self-balancing robots that continuously drive wheels against the ground, this cube uses an internal reaction wheel to control its orientation. When the motor accelerates or decelerates the spinning… |

Maker Replicated the Boston Dynamics Gripper Using Daisy-Chained Servos and 3D-Printed Fingers Maker built a Boston Dynamics–style gripper using daisy‑chained bus servos and 3D‑printed fingers. Inspired by the Electric Atlas Humanoid Robots, the design focuses on a simple three‑finger layout with a rotating thumb to move around objects of different shapes. By linking multiple servos over a single UART bus, the build keeps wiring clean while allowing independent control of each joint for… |
