An Open-Source ESP32-S3 Board Puts a USB UPS on Your Network, With NUT and Tailscale Network cards for big UPS units are expensive, and running a full Raspberry Pi just to watch one UPS can feel like overkill. Reddit user Smooth_Ganache897 hit both problems: a garage UPS keeping a camera alive had a dead battery when it was needed, and a rack-mount APC unit needed a costly network card. The answer is ups-to-esp32, an open-source ESP32-S3 board that plugs into a UPS's USB port… |

How to Build an ESP32 Offline Speech Recognition Speech recognition models like OpenAI’s Whisper offer high levels of accuracy, but their base model itself consumes up to 140MB and running them on a low-end device like an ESP32 is difficult. In this tutorial, we are going to run Cactus Compute’s Whistle Speech-to-Text Model launched on 2nd of October 2026. The actual size of the model is 16.9MB, which won't fit… |

Is 30 FPS Killing E-Paper? A Maker Ran 2.16 Million Frames on an ESP32-S3 to Find Out E-paper is supposed to be slow: great for shelf labels and e-readers, terrible for games. So when makers started running Game Boy games at 30 frames per second on cheap e-paper boards, two questions came up fast. Does the display eat the battery, and does it wear out? Bo Made It, who wrote the fast driver in the first place, measured both on a Waveshare ESP32-S3-ePaper board. The answer to the… |

How to Run Wikipedia Offline on ESP32 These days, we are heavily dependent on cloud computing, high-speed internet and all. We rarely think about what happens if the internet goes down or what happens in areas where the network is not reachable or information access is very difficult. The main solution is having the data and its processing locally so that they are reachable anytime, even without internet… |

This Original NES Now Has a Desktop, a Mouse and a Web Browser That Plays YouTube, Thanks to an FPGA Cartridge and an ESP32-S3 The Nintendo Entertainment System was never meant to be a computer. It has a 6502-based CPU, 2 KB of RAM and two controller ports. Yet Throaty Mumbo has turned his NES into something that looks and behaves a lot like a 1990s desktop PC: a Windows-style desktop with a start menu, files and a trash bin, a USB keyboard and mouse, a MIDI keyboard, CD and DVD playback, and a web browser that can… |

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… |
