This repository is a curated directory of internet radio streams, organized by genre, with automated tooling to generate M3U playlists, check link health, and probe stream availability. It is primarily a data curation project, with the README.md serving as the source of truth. The supporting scripts form a robust data pipeline: parsing the markdown, generating playlists, and running health checks with retry logic and silence detection. The project demonstrates strong data engineering practices in a non-traditional data context, with shared parsers, persistent state tracking, and CI workflows that handle race conditions gracefully.
This repository provides a comprehensive collection of Arduino-compatible libraries and examples for developing applications with LilyGo LoRa-based development boards. It includes libraries for LoRa wireless communication (RadioLib), display interfaces (TFT_eSPI, GxEPD, U8g2), sensor integration (SensorLib), button handling (AceButton), GPS parsing (MicroNMEA), and power management. The architecture follows a modular library pattern with extensive example applications demonstrating various use cases like point-to-point LoRa communication, LoRaWAN nodes, GPS tracking, sensor data display, and remote control systems. The codebase demonstrates good software engineering practices with clear separation of concerns, hardware abstraction layers, and well-documented components.
VxeTable is a Vue 3 component library for building complex, enterprise-grade data tables and grids. It provides a comprehensive set of features including virtual scrolling for millions of rows, inline editing, Excel-style copy-paste, column resizing/dragging, filtering, sorting, pivot tables, tree/gannt views, and export/import/print. The library is architected as a set of Vue components (VxeTable, VxeGrid, VxeColumn, VxeToolbar, VxeColgroup) with an extensible plugin system based on hooks and renderers. It relies on a companion UI library (vxe-pc-ui) for modals, buttons, selects, and other controls, and uses xe-utils for utility functions. The codebase is large and well-organized, with separate modules for editing, filtering, keyboard navigation, validation, column customization, and export. Performance is a key focus, with virtual scrolling implemented for both X and Y axes. The library supports i18n with over 20 languages and includes a comprehensive theming system with light/dark modes. While primarily a UI component library, it also includes proxy-based server-side data operations in the VxeGrid component. The repository includes a demo application (examples/) for testing features, though the main artifact is the published npm package.
This is a full-stack, self-hosted satellite ground station, not a data-research repository, though it contains substantial orbital-data ingestion, telemetry parsing, and signal-processing components. The application connects software-defined radios (RTL-SDR, Airspy, UHD, SoapySDR, SDRplay) to a real-time web UI for satellite tracking, hardware control, IQ/waterfall visualization, demodulation, decoding, recording, and observation scheduling. The backend is Python with FastAPI/Socket.IO, SQLAlchemy/Alembic, multiprocessing workers, and pub/sub broadcaster components; the frontend is React/Redux Toolkit/Material-UI. The user-facing system manages rotators and rigs via Hamlib, propagates TLE/OMM orbital elements, predicts passes, applies Doppler correction, schedules automated observations, and exposes file browsing, telemetry analysis, and audio transcription through external AI providers.
This repository is an open-source hardware collection of RF front-end modules for low-cost RTL-SDR receivers, not a software application or data research pipeline. It is classified as application because its primary deliverable is a set of manufacturable PCB designs, schematics, and assembly documentation for discrete SDR building blocks. The repo contains complete design packages for an HF upconverter, multiple low-noise amplifiers with bias-tee powering, an SPDT antenna switch, a Mini-Whip active antenna, a balun, a PI attenuator, an RF power limiter, and fixed-voltage coax power supplies. Each module follows a consistent directory pattern: EasyEDA source files, Gerber exports, PDF schematics, component lists, datasheets, assembly guides, and enclosure model files. The RF signal flow runs from antenna through Mini-Whip, upconverter, filters, LNA, and protection stages into an RTL2832U-based SDR, with power injected over coax via bias-tee circuits. The real value of this repo is its modular, reproducible hardware architecture: well-documented bias-tee/power-over-coax designs, Mini-Circuits-based LNA and limiter circuits, and reusable RF layout techniques such as via stitching, ground pours, and controlled-impedance traces. The EasyEDA JSON files are tool-specific but self-contained and importable, and the Gerbers are ready for fabrication. Markdown guides cover component sourcing from LCSC, PCB ordering from JLCPCB/PCBWay, and Linux RTL-SDR setup, including known pitfalls like rtl_biast breakage after sudo make install. The project is explicitly described by the author as a final stable release with support ended, though recent commits in 2026 added new balun and RF power limiter designs, so the repository remains active. Limitations: this is hardware design data, not executable software, so there is no code to run, test, or integrate. The EasyEDA JSON format and .ftr filter design files are proprietary, some component choices (BF998, J310, ADE-1+, DF782, TC9-1+) are at risk of obsolescence, and the repository mixes EasyEDA editor versions from 2020 and 2026. For an engineer, the most reusable assets are the bias-tee power supply schematics, the balun and LNA reference designs, and the consistent module packaging pattern that makes each board a drop-in SDR building block.
This repository is a curated collection of live TV and radio channel playlists (M3U format) along with supporting web tools. It provides direct-access channel logos, an EPG (Electronic Program Guide) via Cloudflare Workers, a web-based HLS player, a streaming download proxy using ServiceWorker, and a TXT-to-M3U converter. The architecture is a static site hosted on GitHub Pages and Cloudflare CDN, with serverless functions for data aggregation. The primary data flows involve fetching EPG from external sources (112114.xyz, celetor/epg) and radio metadata from radio.cn, then serving them through Workers. The playlists aggregate hundreds of Chinese and international channels, but rely on third-party stream URLs that may become stale. The codebase is functional and well-documented, but contains some outdated vendored libraries (Vue.js 2.6.10) and external dependencies that introduce drift risk. It is not a software library but a practical toolset for IPTV enthusiasts.
