REA is an open-source Model Context Protocol server that connects coding agents to local reverse-engineering tools for inspecting native binaries, JavaScript/Electron apps, .NET assemblies, Android APKs, firmware, websites, and network captures. It integrates with Hopper, Ghidra, and IDA for deep native analysis, and provides static JavaScript and .NET inspection without requiring a native analysis engine. Results include evidence and limitations behind each conclusion, and the project is available under the MIT license.

theleestarr writes an open-source ESP32 firmware designed for 1.28″ round displays that functions as a sonar-style radar showing live ADS-B aircraft data around a user's location. The project is compatible with the Waveshare ESP32-S3-LCD-1.28 and can also be used with an ESP32-C3 Super Mini paired with an external GC9A01 display.
- Uses live traffic from adsb.fi
- Features selectable range scales (5, 10, 15, or 25 km) via the BOOT button
- Provides optional runway overlays for major airports
- Includes a sonar-style UI with aircraft symbols, callsigns, and altitude data

tzapu writes about WiFiManager, an Espressif ESPx WiFi connection manager featuring a fallback web configuration portal. The library allows devices like the ESP8266 and ESP32 to automatically enter Access Point mode if they cannot connect to a saved network, enabling users to configure credentials via a captive web portal from any device with a browser.
- Supports both ESP8266 and ESP32 platforms
- Features a captive portal that redirects all traffic to the configuration page
- Includes support for custom parameters beyond SSID and password (e.g., MQTT settings)
- Provides language switching options including German, Spanish, French, Portuguese, and Brazilian Portuguese
- Supports on-demand configuration portals via a trigger pin or software command

Tyler August writes that the Cheap Yellow Display (CYD) ESP32 dev boards can be transformed into a Portable Digital Assistant, reminiscent of 1990s Palm devices. Rather than using an emulator, user sau412 developed custom firmware for the CYD that includes features like a Gopher browser, RSS and Wikipedia readers, various games, a BASIC interpreter, a calendar, calculator, contact list, ebook reader, and translator.
- The project can be set up in approximately five minutes using a web-based flasher.
- An SD card is required to test all the available applications.
- This project provides an alternative for those looking for Palm OS-style functionality on modern hardware without needing x86 or ARM emulators like Pumpkin OS.

This page provides instructions and tools to install or update the Pocket Tank application on supported hardware, specifically the Waveshare ESP32-S3-Touch-AMOLED-1.8 board. Users can perform standard installations, updates that preserve existing data, or a full wipe via an "Erase" function using compatible web browsers like Chrome or Edge.
- The app includes a 7.5 MB model for local processing; no external communication is required once installed.
- Updating the firmware preserves fish names, badges, sand dollars, and decorations.
- To reset the tank manually without this page: hold `BOOT` and tap the screen to confirm the wipe.
- Troubleshooting involves waking a sleeping device by firmly pressing the `PWR` button or putting it into bootloader mode using `BOOT`.

eenk is a custom firmware for Xteink ESP32-powered e-ink reader devices that turns them into dedicated interactive fiction players. Stories are written in inkle's Ink scripting language, compiled via the eenky IDE (a fork of Inky), and run on-device using the inkcpp C++ runtime. The project includes a browser-based web flasher for firmware installation and library management over USB with no drivers or WiFi required.
- Supports three hardware models: X3 (ESP32-C3, 792×528), X4 (ESP32-C3, 800×480, USB-C), and X4 Pro (ESP32-S3, 800×480, touchscreen, backlight)
- Uses Papyrix firmware's text layout and rendering pipeline for custom fonts that can be applied per story or globally
- Images (cover art, thumbnails, inlined) are bundled with stories using the same pattern as Inky's web export

This documentation details the various network endpoints available when CrossInk is operating in File Transfer or Calibre Wireless mode. It covers HTTP requests for file management, device status monitoring, and system settings configuration via specialized APIs. Additionally, it describes WebSocket protocols for fast binary uploads, WebDAV support for external file managers, and UDP discovery services used to locate the device on a network.
- Uses port 80 for HTTP/WebDAV and port 81 for WebSocket uploads
- Supports both Station (STA) and Access Point (AP) network modes
- Employs a custom UDP discovery mechanism via port 8134
- Implements a specific START:<filename>:<size>:<path> protocol for WebSockets

Alex Kretzschmar writes about building a live aircraft radar using an ESP32-C3 and a 1.28-inch round display to track ADS-B traffic by plotting distance and bearing. He improved the original firmware to include flight context such as origin/destination, descriptive aircraft types, local weather data, and adjustable text sizes via a web interface.
