VolAnti: An Open-Source ESP32-S3 Device That Detects Fibre-Optic Drones With No RF Control Link, Using Sound A maker named Agam Rossen has created VolAnti, an open-source acoustic drone detector that identifies nearby multirotor drones by listening to the sound of their propellers. Unlike traditional drone detectors that look for radio-frequency signals, VolAnti focuses on the sound produced by spinning blades. This approach is particularly relevant to fibre-optic-controlled FPV drones, which send… |

Maker Builds a Wireless 3D Scanner Using ESP32-S3 and Rotating LiDAR That Streams Data to a Custom Android App A maker has built a standalone 3D LiDAR scanner that turns an inexpensive rotating LiDAR module into a wireless spatial-mapping device. The scanner rotates the sensor to collect distance measurements across multiple angles, allowing it to capture the shape of objects and surrounding spaces instead of producing only a flat 2D scan.
An ESP32-S3 acts as… |

How to Identify ESP32 Flash & PSRAM Size ESP32 development boards have been around for years, and we all have been doing a lot of projects with them. They come in various models, with different peripherals, and they perform different levels of tasks. If we are to check into a simple example, we have the normal ESP32 WROOM development boards as well as the same ESP32 with a camera sensor mounted onboard, the… |

Fenix: An Open-Source SI4732 + ESP32S3 Radio That Decodes SSTV Images and Morse Code From Shortwave Signals A small open-source handheld radio called Fennec is turning the ESP32-S3 into much more than a conventional AM/FM receiver. Built around the Silicon Labs SI4732-A10 radio receiver, Fennec can tune FM, AM and shortwave frequencies, decode Slow Scan Television (SSTV) images, translate Morse code into text, monitor radio activity and even help users locate a stronger signal by following its… |
