How PantryAtlas distributes large artifacts on Cloudflare R2 with zero egress fees — the real cost math, why download-cost 'abuse' is bounded by design, the one setting that actually matters, and the gotchas (wrangler's 300 MiB cap, the 512 MB cache ceiling) I hit getting there.
The engineering behind PantryAtlas v0.2.0: an instant→refine→swaps architecture forced by the Raspberry Pi's embedding budget, a ranking formula that only ever settles downward, relaxed-JSON Gemma over grammar-constrained decoding, and offline-first sync that replays on reconnect.
PantryAtlas is local-first culinary AI for a Raspberry Pi 5: tell it what's in your pantry, get ranked recipes back — 49,965 of them, matched on-device, fully offline, no account, no subscription. Here's what it is and how to get it.
A detailed walkthrough of the full stack — OpenCastor, RCAN, LLM providers, Protocol 66 safety — behind two Raspberry Pi 5s holding a genuine planning conversation and coordinating on a real task.
Four new hardware detectors and an expanded I2C lookup table land in OpenCastor v2026.3.12.0 — Dynamixel U2D2, RPLidar/YDLIDAR, Raspberry Pi AI Camera, LeRobot SO-ARM101, plus five new I2C sensor types.
Sixteen issues from a fresh Pi reinstall, now fixed. castor scan, doctor, upgrade, stop, gateway hardening, and a proper venv guide.
Today we release OpenCastor v2026.2.19.0 — an open-source framework that connects any AI model to any robot hardware through a single YAML config. 7 providers, tiered brain architecture, Hailo-8 NPU vision, and a $0 starting cost.
ContinuonOS went from a chatbot wrapper to a complete cognitive architecture in 7 phases, all executed by Claude, Clawdbot, and Gemini working together on a Raspberry Pi 5. Here's how the architecture works, what we tested, and the principles that guide a robot brain designed to live with humans.
