Amateur Radio
Licensed as VK4DSB in QG62. I run a Xiegu X6100 and am active on FT8, APRS, and SSTV. Current projects include a solar-powered Meshtastic relay node.
- Ham Dashboard — Live propagation, APRS, FT8, BOM radar, and DX tracking in one view
- RF Line of Sight Planner — Interactive map for planning RF line-of-sight paths between locations
- Radio Setup — Software and equipment for the X6100
Technology & Security
Open-source tools and write-ups covering incident response, threat intelligence, and network security. Most use local or cloud LLMs as a core component.
- talkIR — Natural-language queries over IR log data; supports Ollama, Claude, and OpenAI
- SignalSage — Threat-intel enrichment bot for Slack and Discord with LLM-generated digests
- forensic-claw — Dockerised DFIR workstation with an AI agent driving Sleuth Kit, Volatility, Plaso, and more
- mesh-medic — Fully offline RAG + LLM over LoRa radio for off-grid use
→ All technology write-ups & projects
AI & LLM
AI runs through most of the projects above — local Ollama models, RAG pipelines, and LLM tooling are core, not gimmicks. The one architecture piece worth its own write-up is OpenClaw setup — a multi-workspace AI agent architecture covering personal, work, and forensic contexts.
