This STM32N6 Turns Speech Into Text Offline Using Its NPU and a 7.2M-Parameter ASR Model The STM32N6 is being used to run an offline speech recognition system that can turn spoken English into text without a network connection. The project runs on the STM32N6570-DK, using its onboard microphone to capture speech and its display to show the recognized words. This system is designed to recognize different English words. At the core is the STM32N6's Arm Cortex-M55 and its ST Neural-… |

Open-Source Pocket Tank Runs a 14.3M-Parameter AI Model on an ESP32-S3 to Give Virtual Fish Their Own Brains Pocket Tank is an open-source virtual fish tank that uses a small AI model to control its virtual fish. It runs on an ESP32-S3 and creates a small aquarium where fish can eat, explore, rest, follow other fish, play, and interact with each other. Each fish has different values such as hunger, energy, curiosity, stress, boredom, and trust, which can change how it behaves. The project was created… |

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… |

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… |

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… |

RP2350 Microcontroller Drives Full 1080p HDMI With No Framebuffer Using Scanline Technique Aaron Gayle’s TV‑Top Kiosk project shows how to squeeze a full 1920×1080 HDMI signal out of a RP2350 microcontroller, which is seen in the popular Raspberry Pi RP2350 development board. To reach 1080p, he overclocked the RP2350 to 372 MHz and used its faster peripherals to generate a DVI/HDMI signal at up to 30 Hz in 24‑bit color. The result is a tiny, low‑cost “console” stick, something like… |

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… |

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… |

He Trained a 2.9M-Parameter AI Image Generation Model, Ran It on a $1 RP2350 Chip and Open-Sourced the Project Generative AI image models usually require powerful processors and large amounts of memory, but a new project demonstrates that image generation can be pushed onto a small microcontroller. Tim, from Tim’s Blog, has implemented a generative AI image model on the RP2350, the microcontroller used in the Raspberry Pi Pico 2. Running on a Waveshare RP2350-Plus board, the system can generate 128×128… |
