AI Edge Device / Private AI Appliance / Tansu OS
Tansu Vault
Tansu Vault is an AI edge device: through our own Tansu OS it brings hardware, operating environment, private AI, knowledge vault, WhatsApp workflow and admin console together into a single deployable private AI appliance.
Tansu Vault is not a single web app but a hardware-to-software integrated appliance. It turns a mini PC or local server into a dedicated private AI workstation running the Tansu OS environment, with kiosk onboarding, WiFi setup, WhatsApp connection, document library, knowledge base, RAG question answering, user permissions, admin dashboard, AI worker, backup, reset and system monitoring.
The architecture includes a Linux-based appliance environment, a locked-down kiosk browser, local network setup, device onboarding, a WhatsApp bridge, self-hosted Supabase / PostgreSQL, file storage, vector search, a RAG pipeline, an OCR service, a hybrid local and cloud model strategy, an admin web console, system services, background workers, a factory reset flow and access control. The design turns ordinary hardware into a private AI operating system that can be delivered to an SME as a finished product.
Hardware / Legacy Device Productivity
PalmVellum × PalmQR
PalmVellum × PalmQR is a hardware productivity project connecting legacy PDAs such as the Palm Pilot and Sony CLIE to modern cloud sync, an AI assistant and a current productivity workflow.
Palm Date Book, To-do, Memo and Contacts data is linked to a modern web app, database, calendar, AI assistant and mobile dashboard. The Palm device becomes a low-distraction, offline-first productivity terminal that still stays in sync with a contemporary working system.
The architecture includes Palm database parsing, HotSync and file sync, a macOS helper app, Supabase / PostgreSQL, calendar records, to-do records, note sync, QR generation, a PWA and mobile interface, and AI assistant integration — legacy offline hardware turned into a modern local-first productivity system.
Hardware / Edge Device Repurposing
CosmoHID × Cosmo Device Fixes
CosmoHID × Cosmo Device Fixes is a hardware repurposing project built around the Planet Cosmo Communicator, converting an ageing mobile device into a genuinely useful input and edge device.
Using the Cosmo's physical keyboard, its mixed Android and Linux environment and its clamshell computing form, the device is repositioned as a Bluetooth keyboard, an edge terminal or a small remotely accessible tool. The emphasis is on software repair, automation and system tuning that keep older hardware in productive service.
The architecture includes an Android IME, Bluetooth HID Device support, low-latency key relay, Doze prevention, persistent Bluetooth pairing, Linux and Android debugging, firmware diagnosis, battery drain analysis, Tailscale SSH, local CLI tools and an edge device maintenance workflow — a demonstration of how software engineering extends the life and usefulness of legacy mobile hardware.
