Astrolabe Pocket
Celestial companion for orientation, time, and rhythm wherever you go.
Castalia Institute
Humane instruments for attention, memory, and rhythm
Astrolabe is the instrument
A shared 1.75-inch round module becomes a pocket companion, desktop dock, musical breath interface, pendant, mindfulness band, or spatial compass. Each form is built to orient, remember, listen, and then hand attention back to life outside the device.

Faculty-guided design
Inquirer Volume IV gives Astrolabe a stricter product rule: AI may assist, retrieve, rehearse, and remember, but the watch must preserve human judgment, source trails, protected silence, and real-world handoff.
Thresholds
Local, cloud, faculty, journal, and shared states should be visible before the user crosses them.
Provenance
Generated replies, readings, and summaries should keep compact source, route, prompt, and human-action records.
Recollection
Rest, reading, studio, sabbath, and seminar blocks reduce prompts and treat non-use as successful use.
Handoff
The best flow often ends in a saved note, a source card, a conversation, a class, a meal, prayer, or sleep.
Design brief: Faculty-Guided Astrolabe
Keep time, moon phase, transits, and bounded Castalia voice answers in a round pocket-watch form.
Desktop dock
Dock to charge, remember, and prepare without turning reflection into another feed.
Breath / music
Use breath, touch, and motion sensors to shape simple musical and focus rituals.
Pendant
Carry memory, quotes, faculty questions, and human-first commonplace notes close to your heart.
Common architecture
All Astrolabe devices share a unified round module and magnetic dock integration. The shell changes the rhythm; the core hardware and firmware lineage stay familiar.
1.75-inch round AMOLED, USB-C charging and data, Wi-Fi, BLE, and offline-capable firmware.
Temperature, heart-rate/PPG, respiration, accelerometer, ambient light, sound, and pressure pathways.
Magnetic alignment, secure hold, charging display, and keyed orientation for accessory shells.
Touch, side buttons, speaker, microphone, and I2C expansion for mount and electrode accessories.
Variant feature matrix
Each release pairs a device platform with a firmware variant, NVS identity, OTA channel, hardware capability set, and default face family.
Founding batch
The first Astrolabe run centers on the Pocket and LunaSay configurations, with Ocarina, Cameo, Enso, and LuoPan shaping an accessory roadmap governed by attention, provenance, recollection, and human handoff.
