A Maker Built a 2.4GHz DIY Yagi With 1mm Brass Rods That Improved ESP32 RSSI From −65dBm to −52dBm A maker has built and tested a DIY 2.4-GHz directional Wi-Fi antenna using a 3D-printed frame and simple brass rods, showing how antenna geometry can significantly change the performance of an ESP32 wireless link. The experiment uses two ESP32 boards, with one acting as a Wi-Fi transmitter powered by a power bank and the other connected to a computer as the receiver. The receiver measures RSSI… |

A Solo Dev Built an OS for ESP32 Boards and Gave Its JavaScript Engine Direct Access to the Hardware An open-source project called KryonOS is a GUI operating system for ESP32 microcontroller boards, built for use with a touch display and an SD card module. Built by a single developer who goes by Haris (GitHub handle Haris16-code) and released under the GPL-3.0 license, it adds a real touchscreen interface, a file explorer, and an app store to hardware that normally runs just one fixed program… |

Running 260K Tiny-LLM on ESP32 We are all facing a huge transition in tech due to AI. In projects, we can run AI models on PCs, SBCs or even Cloud servers. In this tutorial, we are trying to see if we can run an AI model on a microcontroller board like the ESP32. To test this out, we are going to deploy and benchmark the 260K-parameter Tiny-LLM by Andrej Karpathy using his open-source llama2.c… |

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… |

How to Build an Elderly Fall Detection System with XIAO ESP32-S3 When an ageing parent falls at home, the immediate injury is usually only half the danger. The real danger begins during the critical time they spend waiting on the floor for help. Lying immobile for extended periods can rapidly lead to severe dehydration, hypothermia, and muscle breakdown, even in homes where family members are regularly around. Expecting an injured… |

This ESP32-Powered Self-Balancing Cube Jumps With a Spring and Uses a Reaction Wheel to Land on Its Edge A maker from The Tinkering Techie has done a compact self-balancing cube that can launch itself into the air, reorient during the jump, and land upright on one of its edges. Unlike conventional self-balancing robots that continuously drive wheels against the ground, this cube uses an internal reaction wheel to control its orientation. When the motor accelerates or decelerates the spinning… |

Maker Builds a 5-in-1 Cyber Deck Using an ESP32, 3.5-Inch Touchscreen Display, and Custom 3D-Printed Body Maker from the youtube channel Hacktuber recently made a custom "5-in-1 Cyber Deck" using ESP32. He demonstrated the project using two different ESP32 based development boards. One is a 2.8-inch CYD (Cheap Yellow Display) featuring an integrated touchscreen for quick prototyping, and the other is a 3.5-inch non-touch TFT display connected to an ESP32 C3 Mini, mounted onto a 3D-printed… |

Build a Smart Cooker Whistle Counter Using ESP32 Almost every kitchen has a pressure cooker, but we've all had trouble handling them. It’s too easy to turn on the stove, get distracted by work, TV, or housework, and forget to turn it off. If we miss a whistle count, food gets burned, utensils get spoiled, and there are chances of accidents in the kitchen. But then again, being in the kitchen and manually counting… |

ESP32 Camera Dev Board Comparison: ESP32-CAM vs ESP32-S3-CAM vs XIAO Sense-Which Should You Choose?Introduction
ESP32 Cameras have become a popular choice for building low-cost wireless cameras, smart surveillance systems, and even small AI projects. But today, there are several options available, from the original ESP32-CAM to newer ESP32-S3-based camera boards and compact boards like the XIAO ESP32-S3 Sense. At first glance, they may look similar, but there are… |

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… |
