ECOSYSTEM
The DH81 project family spans three GitLab organizations. The main page covers the public SDR tools. This page covers the rest of the ecosystem - private repos under active development and affiliated organizations. These are works in progress; source is not yet public.
Private DH81 repos not yet ready for public release. These extend the SDR ecosystem into TTS, music, AI inference, and device management.
Local Markdown-to-speech reader with Piper ONNX voice synthesis. Native ONNX inference (GUI) and subprocess fallback (CLI). RSVP word-by-word display, voice selection, speed control, WAV export.
Multi-source music player with unified AudioSource trait. Deezer, TIDAL, local files, internet radio. Feature-gated backends, CLI and egui GUI.
Cosmic cycle calculation engine modeling 19 astronomical, solar, planetary, climate, and earth mechanical cycles. Convergence scoring and radio propagation forecasting. Pure math, no network calls. Try the interactive web visualization (science guide).
Iterative paragraph compression via ONNX inference. Reduces text to single-sentence summaries using BART, T5, Flan-T5, or Long-T5 models.
Device backup TUI for Google Pixel and iPhone over USB. Native protocol stacks: idevice for iPhone, adb_client for Pixel.
Offline RAG chatbot over local markdown corpus. BM25 keyword search, llama.cpp CUDA inference.
