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… |

ESP32-Based AI Pet Gets Sick If You Doomscroll, While Android Handles Local LLMs, STT, and TTS Offline Maker and Youtuber, Brenpoly recently built an offline AI virtual pet that lives on an ESP32 and “gets sick” when you doomscroll too much, turning screen-time guilt into a tangible, hardware-based consequence. The project makes use of the 1.8 inch touch screen display and sensors that come integrated with the Waveshare ESP32-S3 based module to create a companion that reacts to your phone usage… |

Maker Turns an ESP32 S3 Into a Pocket PC by Porting Open Source Tactility OS to a 2.4 Inch Touch Display This project transforms a compact MaTouch Lite development board into a fully functional, portable touchscreen computer. The project uses an ESP32-S3 microcontroller, featuring 16MB of flash and 8MB of PSRAM, which provides the necessary performance to run a graphical environment. By integrating a 2.4-inch resistive touchscreen and a microSD card for storage, the creator successfully… |

ESP32 Video Player: SD Card to TFT Display Playing smooth, full-motion video on low-power microcontrollers has been challenging due to memory and processing limitations. But with the dual-core speed, high SPI clock rates and an optimized decoding library on the ESP32, you can turn a simple development board into a working video player. If you want to create custom animations or add dynamic visual UI elements… |

Maker Built His Quadruped Robots a Soccer Field Where Ball Tracking Improved With Less Accurate Camera Data A maker built a miniature soccer environment for Sesame, a small quadruped robot, and demonstrated the system at the 2026 Open Sauce maker event. The build includes a scaled down soccer pitch sized for the robot, along with 3D printed goals and structural components. Multiple Sesame units are controlled wirelessly using the ESP-NOW protocol, with ESP32 chips on each robot communicating with a… |

This Maker Turned a Simple Stick Into a POV Display Using a Teensy 4.1, ESP32 and Fast APA102 LEDs YouTuber Zachary McCune from Corridor Crew has turned a simple fire spinning hobby into an ambitious engineering project that can create images in the air while spinning. The project uses the principle of persistence of vision (POV), where rapidly changing lights appear to form a continuous image when moved quickly through space. Instead of using a conventional screen, the device displays an… |

ESP32-CAM AI Vision Assistant Pendant for the Visually Impaired Moving through unfamiliar environments is a challenging thing for visually impaired people. We have a lot of solutions, from sticks to obstacle-avoidance handheld devices on the market, to solve their problem. In the DIY world, a lot of makers have built obstacle-avoidance sticks using Ultrasonic sensors, IR sensors or even a PIR sensor and different variations of… |

TICKEY Is a Small Clip-On Badge With an E-Ink Display That Can Show 48 Colors, Built on an ESP32 TICKEY is a compact clip-on gadget that combines a 3.7-inch, 720 × 480 color e-paper display with an ESP32-S3 microcontroller, Wi-Fi, Bluetooth and NFC. Instead of behaving like a normal LCD or OLED screen, its e-paper display is designed to keep a static image visible without continuously consuming display power. Users can show pixel art, photos, digital badges, QR codes, notes or personal… |

A Drone That Tracks Its Leader Using Four Microphones and an ESP32, No GPS or Camera Needed Researchers at Duke University's General Robotics Lab have built a system that lets one drone follow another using nothing but the sound of its rotors. The project, called SonicFly, estimates a leader drone's bearing and distance from onboard audio alone, without GPS sharing, cameras, radio links, or any active signal exchange between the two aircraft. … |

How to Build an AI-based Air Quality Monitoring using ESP32 Air is a necessity for us human beings, so monitoring it is important. Air quality is monitored in terms of the Air Quality Index(AQI), a single-number scale used to tell how polluted the air is and what health effects it might cause. Particulate Matter is the microscopic solid or liquid which is present in air in the form of dust or smoke. Particulate Matter is the… |
