Hey r/cyberdeck ,

Time for an update, and this one's a bit personal. Two big things: V1 is on pause, and V2 is taking shape as something much more ambitious. Here's the full story.

Why V1 is paused

First, the personal part: I'm going to be a father. 🎉 That changes priorities, time, and — very practically — available space. The final integration of V1 (a Raspberry Pi 5 build in a hardcase) is on hold because I simply don't have the room right now to do the internal mounting properly. It's not abandoned — V1 works and runs fine — but getting everything mounted cleanly needs space I temporarily don't have. So rather than rush a messy job, I'm pausing it and shifting focus.

Why V2, and why it's different

V2 isn't a V1 iteration — it's a rethink. The core idea: separate compute from display. Instead of everything in one case with a screen, V2 is a modular "mini server in a backpack" with a thin-client on your face.

The big specs:

- Compute: NVIDIA Jetson Orin Nano Super (8GB) — moving from the Pi's CPU inference to actual CUDA GPU inference. This is the heart of the whole thing.

- Display: RayNeo Air 4 Pro AR glasses as the screen, over USB-C. Used when stationary/opened.

- Audio/voice on the move: a pair of Vocalskull audio sunglasses — open-ear, discreet, with a mic. When I'm moving with the bag closed, this is the interface: voice in, voice out, no screen. The glasses are the visual side; the shades are the "eyes-free" side.

- Power: AllPowers S200 + a UPS layer on the Jetson, with a buck/boost converter planned so it can charge from car batteries too.

- Storage: dual NVMe internally (2280 + 2242) plus the existing 4TB SSD, with a separate detachable "panic" NVMe that holds a daily encrypted backup of the critical stuff — grab-and-go.

- Comms: RTL-SDR V4, Meshtastic (a fixed internal node via GPIO + my T-Deck as a portable node), and a Pi Zero 2W doing triple duty: RetroPie, an offline incident-gateway, and a network buffer between the internet and the Jetson.

The AI side — this is where it gets fun

The system runs local, offline AI via Ollama with multiple personas, each with their own role:

- Vesper 🧠 — the system core. Knowledge, search, hardware control, tool-calling. The "everything assistant."

- Luna 🌙 — emotional support and reflection. In a crisis, people break mentally before they break physically. This one matters.

- Nova 🧸 — a safe, child-friendly educational companion. And here's where it ties back to the personal part: if things ever go sideways in the world, I want a foundation of learning for my kid even without schools around. Nova is built for that, locked behind admin PIN, fully sandboxed.

A lot of the recent work has actually been in Obsidian — I've been writing out each persona's identity, behaviour and boundaries as markdown files, building a knowledge vault that the AI can draw from, and structuring emergency procedures Vesper can pull up on command. It's been a surprisingly personal process: you end up really thinking about w…
