This project transforms the LILYGO T-Display-P4 development board into a multifunctional portable device capable of acting as a 1090 MHz ADS-B receiver and a Meshtastic-compatible mesh radio. By using an RTL-SDR USB dongle for RF reception and an onboard SX1262 LoRa radio, the system provides real-time aircraft tracking via a touchscreen interface and off-grid messaging capabilities. The device also features integrated MP3 playback, GPS time synchronization, and a companion web application called ADS-B Scope for live map viewing through WebSerial.
Main features include:
* Real-time ADS-B decoding and radar scope visualization with aircraft database enrichment.
* Meshtastic-compatible LoRa mesh networking with encrypted messaging and node discovery.
* Integrated MP3 music player with ID3 tag parsing and cover art display.
* Adaptive RTL-SDR gain control and USB hot-plug support.
* Comprehensive SD card logging for both ADS-B flight data and mesh messages.
* Dual-core ESP32-P4 architecture optimized via a 6-tier FreeRTOS priority scheme.
* WebSerial-based companion app for live mapping, firmware flashing, and file management.

The NanoFarfield is a portable far-field measurement system for low-cost vector network analyzers like the NanoVNA and LiteVNA. It features a motorized rotation platform, amplifier, RF limiter, and measurement software to produce accurate radiation patterns and gain measurements. It's designed to be affordable, reproducible, and accessible for RF engineers, researchers, and makers.
OpenEmbed is creating the MeshWalkie, a Meshtastic-ready LoRa handheld using the housing of a Baofeng UV-K6 radio. It features an Espressif ESP32-S3, a Seeed Studio Wio-SX1262 LoRa transceiver, and a Seeed L76K GNSS receiver, all on a custom PCB. The project aims to provide a rugged, open-source alternative to 3D-printed or expensive injection-molded handhelds.
