ESP32-S3 Boards Detecting Human Movement Using Wi-Fi This DIY ESP32-S3 Wi-Fi Sensing System Detects People and Tracks Movements Without a Camera at 80% Accuracy

Better Stack from Youtube recently used an open-source project called RuView and explored how Wi-Fi signals can be used to detect human presence and movements without relying on a camera. He describes how Wi-Fi signals change as he travels through a room and bounce off walls, furniture, and people. When someone moves, their body alters the signal's strength and phase across different frequency…

Handheld ESP32-S3 Color Picker Scanning Real-World Object This ESP32-S3 Real Life Color Picker Brings the Digital Eyedropper to the Real World With RGB and HEX Values

Tech Talkies Youtube channel has built a handheld color picker using the ESP32-S3 that can scan the color of a real-world object and show its RGB and HEX values on a small display. Users can point the device at a surface, capture its color, and see the result without relying on a phone camera or computer. This makes it useful for designers, makers, artists, and anyone who wants to quickly…

ESP32-S3 Running Metal Gear Solid on Custom 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…

Portable Digital Compass With Round Color Display 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…

At first glance, they may look similar, but there are…

VolAnti ESP32-S3 Acoustic Drone Detector With Display 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…

Wireless 3D Scanner With ESP32-S3 And Rotating 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…

Identifying ESP32 Flash and PSRAM 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.
