Band Assist

A camera-based practice companion for musicians — watching hand position and technique in real time and translating it into plain-language coaching, entirely on-device. No cloud dependency, no subscription, no audio or video ever leaving the room. Built around a three-model local AI stack: hand-landmark tracking, an instrument-agnostic technique analysis model, and a small quantized language model that turns raw error signals into spoken feedback a student can actually act on.

System Architecture

Vision and audio are fused on-device across three purpose-built models running on the NPU: a hand-landmark tracker locating finger and wrist position frame-by-frame, an instrument-agnostic analysis model translating that motion into a defined technique-error taxonomy, and a small quantized language model converting those errors into natural spoken coaching. A 7-microphone array supports pitch and timing analysis alongside the visual pipeline, so feedback draws on what the student played, not just how they moved.

Cartridge 01

A standalone digital audio transport engineered to return intentional tactile interaction to personal music listening. Operating on an isolated environment stripped of background computational processes, it bypasses modern mobile phone distractions to deliver an uncompromised, hyper-focused bit-perfect listening workflow through hot-swappable hardware media components.

System Architecture

Structured explicitly around the Rockchip RK3566 compute module paired with a custom low-overhead kernel. The physical topology utilizes a high-mass internal aluminum shielding chassis nestled inside a ruggedized external protective profile shell. Sound processing relies on an independent, isolated high-fidelity digital-to-analog block handling native high-resolution containers natively without interpolation or software downsampling.

The ARC Platform

An open-source, completely modular, reference-grade wireless audio matrix engineered to transition personal monitors from disposable consumer electronics into a fully modular hardware sandbox. By physically segregating acoustic volume constraints from active silicon expansion systems across a master bus architecture, the platform opens hardware development to custom community physical modifications.

Functional Topology

  • Dual-Core Processing Array: Managed via an nRF5340 processing node dividing network communication protocols on an isolated core from high-level application code execution and expansions.
  • Acoustic Isolation Vault: An internal solid dividing bulkhead forms a permanent, hermetically sealed forward enclosure behind the titanium drivers, preventing environmental sound leaks through outer components from manipulating audio parameters.
  • Master Bus Sandbox: An embedded 40-pin connector array mapping multi-rail power distribution layers, serial command lines (SPI/I2C), multi-channel digital audio formats, and raw microphone feeds.
  • Toolless Magnetic Outer Shells: Exterior modular cosmetic and dynamic plates utilize alternating polarity indexing magnets for seamless mechanical seating, reinforced by sliding compression locking latches.

Concept Study

The Meridian Programme.

An early-stage, self-directed exploration into off-grid tactical communications hardware — mesh radio, evidence handling, and modular field electronics developed as a single coherent product family. Shelved in favour of current priorities, kept here as a record of scope and systems thinking rather than a live product line.

Reference Platform // Consumer & Open Hardware Variant

Meridian Go / Meridian One

A handheld, fully off-grid communications device — LoRa mesh radio, offline GPS navigation, an evidence-grade camera, and environmental sensing, with zero dependency on cellular, Wi-Fi, or satellite infrastructure. Meridian One is the fully open-source sibling variant: identical hardware, published schematics, firmware, and enclosure files.

Meridian Pro

Dual-core STM32MP257 platform adding cellular mission-critical push-to-talk with automatic 2-second LoRa fallback on signal loss, GPS evidence tagging, and an Officer-Needs-Assistance trigger broadcasting location the instant it's raised.

  • UWB ±10cm ranging, functions GPS-denied and underground
  • Automatic man-down detection via 6-axis IMU
  • Three independent ONA triggers — button, voice phrase, dual-key hold

Walkie Module

A clip-on module housing the cellular push-to-talk modem, bodycam, and LiDAR — kept physically separate from the main handset so removing it for EMCON strips all cellular capability cleanly, in one motion.

  • Sony IMX335 bodycam, 120° FOV, 30-second pre-event buffer
  • Sony IMX591 direct-ToF LiDAR — depth mapping in total darkness

Infrastructure
Infrastructure // Sync

Meridian Dock

Spring-loaded pogo-pin docking — no cable to align in the dark, works wet, glove-friendly. Drop the device in and a 15-second interaction window runs before it locks and syncs automatically.

  • Sync priority: photos → GPS logs → messages → bodycam → the rest
  • Overnight OTA firmware updates, signed & rollback-safe
  • Vehicle cradle triggers immediate sync, no interaction window
Infrastructure // Command

Meridian Command

On-premise server software — a mapped, hash-chained record of every device's activity, running entirely on local hardware with no cloud dependency for evidence or location data.
