ESP32 Bit Pirate

An open-source project that runs a 28.9-million-parameter language model locally on an ESP32-S3 microcontroller, without network connectivity. It uses a tiered memory layout based on Per-Layer Embeddings: frequently accessed activations and normalization weights stay in SRAM, the model core and output head reside in PSRAM, and a roughly 25-million-parameter embedding table is stored in flash; only the few rows needed for each token are read into faster memory. The included TinyStories model generates short stories, while a Barista model provides espresso question answering. The repository notes that the TinyStories model is not designed for general question answering, instruction following, code generation, or factual knowledge, and provides separate scripts for downloading and verifying model assets and deploying a selected model to the board.

HoloCubic_AIO is open-source all-in-one firmware for the HoloCubic ESP32 device, developed around the ESP32-Arduino platform. Its modular framework combines applications including weather clocks, a photo album, MJPEG or RGB video playback from a FAT32 TF card, desktop screen sharing, effects animations, a 2048 game, Bilibili follower information, anniversaries, heartbeat messaging over MQTT, stock quotes, and web-based configuration. The firmware provides a web server for Wi-Fi setup, system and application settings, self-starting application selection, and wireless file management or uploads to the TF card. It also supports an access-point setup mode, browser access through a local IP address or the `holocubic` hostname, and a companion open-source desktop tool for firmware flashing and media conversion. The repository contains the firmware source and documents ESP32-Pico Arduino and PlatformIO build requirements, MPU6050 startup calibration, TF-card dependencies, and application-specific network or file requirements.

M5Stack is a modular hardware and open-source software platform for IoT prototyping and deployment. Its standard 5 × 5 cm system uses stackable functional modules built around an ESP32 microcontroller, with features including a microSD card slot, USB-C port, and expansion connectors. M5Stack also provides multifunctional base modules and ODM services for projects ranging from prototypes to mass production. In the cited video, M5Stack hardware is used by VibeWatch as a smartwatch interface for controlling multiple AI coding agents.

wifit3 is a standalone USB Wi-Fi auditing tool for Linux, Windows, and macOS. It requires a supported USB wireless adapter and uses pure Python with PyUSB and Textual rather than aircrack-ng or reaver. The tool bypasses the operating system's native Wi-Fi stack through lightweight Python ports of Linux wireless drivers that control adapters over USB bulk and control transfers. It provides channel-hopping reconnaissance across 2.4 GHz and 5 GHz networks, multi-adapter packet capture, access-point and client identification, hidden-network correlation, and packet-rate monitoring. Its auditing functions include WPA/WPA2 handshake and PMKID capture, targeted deauthentication, WPA3 downgrade attacks, WPS PixieDust, push-button and PIN recovery, and WEP techniques such as ARP replay, ChopChop, fake authentication, and PTW key recovery. Captures can be exported as PCAP or HC22000 files. Prebuilt executables are available for Windows, Linux, and macOS, and the project can also be run or built from source with uv and PyInstaller. It configures the required device access through udev and modprobe rules on Linux, WinUSB on Windows, and an authorization prompt on macOS. The code is licensed under GPLv2; bundled vendor firmware is distributed under the respective manufacturers' licenses. The project states that it is intended only for networks and equipment owned by the user or explicitly authorized for auditing.
