A Son Built His Offline Dad an ESP32 E-Paper Frame That Shows Which Airliner Is Flying Over the Alps Right Now Daniel Zellhuber's father lives in the Bavarian mountains, loves watching planes cross the sky, and does not use the internet. So instead of showing him a flight-tracking app, Daniel built him a small flight tracker in a picture frame. Whenever an airliner passes overhead, the colour e-paper screen shows the airline with its logo, flight number, route, aircraft type, speed and altitude. There… |

This Giant 3D-Printed Wheel Writes Endless Scrolling Text With Black and White Marbles, After 30+ Hours of Testing Marble machines usually stop at clocks, with a fixed number of digits and a fixed amount of space. Ivan Miranda wanted a display that never runs out of room. His new Marble Scroller is a huge 3D-printed wheel that writes text in black and white marbles using a 7x5 pixel font, lets each line roll off the other side and then recycles the same marbles to write the next one. It can do uppercase,… |

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… |

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… |

How to Build a Smart Wireless Doorbell System Using IoT Missing a visitor at the front door usually means missed package deliveries, keeping friends waiting outside, or missing unexpected guests. Standard doorbells only work if we happen to be sitting nearby and the chime is loud enough to hear. If we are stuck in a work meeting, listening to music with headphones, or away from home, it is easy to miss the ring, leaving… |

ESP32-Based Smart Mailbox Uses Computer Vision to Detect Packages and Trigger Motorized Doors and Alerts The project documents a fully automated smart mailbox built by Re-Crafting DIY. It integrates advanced electronics to solve practical issues like package theft, weather damage, and inadequate storage space. By repurposing an old car’s wiper motor for the door mechanism, the mailbox features a heavy-duty, motorized front door controlled by a central brain. It might have been a little too much… |

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… |
