Dragonfruit is an open-source emulator of the Motorola DragonBall processor that runs Palm OS 3.x on ESP32 devices like the M5Paper, supporting stylus input, ROM loading, and add-on installation.

The author successfully implemented a playable Gameboy emulator on the M5 Paper S3 (ESP32 S3 + e-ink display). By using high refresh rate driving, an optimized emulation core, and an innovative pseudo-polyphonic sound scheme, classic games run smoothly on the e-ink screen.

A tech video showcasing a full-stack project using ESP32 hardware, frontend, backend, voice agent, and AI music composition, reflecting the comprehensive development capabilities in the AI era.

A developer hacks a Wi-Fi smart light bulb with Tasmota firmware to create a covert digital archive of banned books accessible via an open WiFi network.

An ESP32-powered alarm clock that wakes you up by discharging a capacitor through a loud bang. The project includes a custom PCB, 3D printed case, and web interface for configuration.

A developer built a local voice-controlled music system using an ESP32 microcontroller, a MacBook, Magenta Realtime 2 for real-time music generation, MLX Whisper for transcription, and a Qwen model for tool calling, enabling conversational control over music elements like genre and instruments.

This project turns an ESP32-S3 development board into a USB drive that appears to contain every possible file, inspired by the Library of Babel. It's a fun hack that generates arbitrary file contents based on path names using MTP protocol.

ESPectre is an open-source tool that uses Wi-Fi channel state information (CSI) on ESP32 devices for privacy-preserving motion detection, with native Home Assistant integration via ESPHome.

A Japanese broccoli farmer with no engineering background used OpenAI's Codex to build custom DIY automation tools for his 100-hectare farm, including remote greenhouse vent control and temperature monitoring.

ESP32 Bit Pirate is an open-source firmware that turns an ESP32 into a multi-protocol hacking tool, supporting sniffing and interaction with various digital and radio protocols via serial or web-based CLI.

Roku has released the LT Operating System as an open source distribution, supporting ESP32 and Linux platforms. The page provides build and flash instructions for developers.

Muxcard is a fully functional DIY computer the size of a credit card, built around an ESP32-C3, e-paper display, and NFC, with potential use cases including wallets, pentesting, smart-home control, and more.

A hobbyist built a functional self-powered computer that is literally the size of a credit card and about 1mm thick, using an ESP32, NFC, e-ink display, and custom flex PCB.

The open-source project AI Desk Card combines e-ink hardware with AI Agent to intelligently display schedules, to-dos, GitHub activity, and more, supporting voice or text interaction without needing a phone app to configure.

The developer spent 14 months creating an AI physical prototype device named Keito, based on the ESP32 chip. It supports features such as voice conversation, real-time lip-sync animation, capacitive touch interaction, music playback, and weather query, aiming to liberate AI from the text box.

M5Stack PaperColor is a 4-inch color E-ink development board powered by ESP32 with audio I/O capabilities.

NumOS is an open-source operating system for graphing scientific calculators based on the ESP32-S3 microcontroller, featuring a Giac-backed CAS engine and LVGL 9.x interface.

An open-source motion detection system that uses Wi-Fi Channel State Information (CSI) on ESP32 devices, with native Home Assistant integration via ESPHome.

RuView is an open-source WiFi sensing platform that uses Channel State Information (CSI) from low-cost ESP32 sensors to detect people, track movement, measure vital signs, and estimate pose through walls without cameras or wearables. The system runs entirely on edge hardware with cryptographic attestation and uses spiking neural networks for local adaptation.
