Open-Source Pocket Tank Runs a 14.3M-Parameter AI Model on an ESP32-S3 to Give Virtual Fish Their Own Brains Pocket Tank is an open-source virtual fish tank that uses a small AI model to control its virtual fish. It runs on an ESP32-S3 and creates a small aquarium where fish can eat, explore, rest, follow other fish, play, and interact with each other. Each fish has different values such as hunger, energy, curiosity, stress, boredom, and trust, which can change how it behaves. The project was created… |

This DIY Open-Source mmWave Presence Sensor Features ESP32-C6 With Precision 2D Spatial Tracking Traditional infrared presence sensors are cheap, but unreliable for smart homes, often turning off lights if you remain still for even a few seconds. Millimeter-wave (mmWave) radar modules offer a far superior alternative by detecting micro-movements like breathing and even tracking a person's exact 2D position in a room. However, commercial mmWave presence sensors can cost anywhere from $40… |

This Arduino UNO Q Headband Uses 13 Vibration Motors for Screen-Free Awareness Through Haptic Feedback Maker pasquale887 has developed HaloSense V1, a wearable haptic headband that helps users sense the direction of people and objects through vibrations instead of looking at a screen. The headband has 13 small vibration motors arranged around the forehead. When a person or target is detected in a particular direction, the motor in the corresponding position vibrates, helping the wearer… |

This Open-Source DIY Drone Uses FMCW Radar and RTK GPS for High-Resolution SAR Imaging and Ground Mapping This DIY drone is doing something much more than taking aerial photos. It uses a custom FMCW radar to create detailed images of the ground from the air.This is built by Henrik Forstén.The system sends radio signals toward the ground and measures the signals that bounce back. As the drone flies, it collects thousands of these measurements and combines them using Synthetic Aperture Radar (SAR)… |

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… |
