Instruments for seeing the networks around you.
The air is full of radio. We draw it.

Every room you walk into is crowded with networks you cannot see: routers, repeaters, telephones asking after networks they once knew. The usual tools describe all this in tables, accurate, exhaustive and very nearly unreadable. Starchorus draws it instead, as a sky that turns slowly about you, and every mark in that sky still answers to a measurement.

starchorus/pager turns a Hak5 WiFi Pineapple Pager into an observatory. Access points are stars, coloured by band; their clients orbit as satellites; the stronger the signal, the closer to the centre. It listens and never transmits.

Foundation: the quiet chart	Whitehall: the plotting table	Orbit: the sky in three dimensions

One self-contained page, three looks, two and three dimensions; baseline comparison, inventory, air quality, signal over time, recording and replay, and a homing meter. Since 0.2 it can also draw the Bluetooth addresses around you and each channel's share of the frames heard (both off until switched on) and, on a phone, a Scope that places signals by band and strength; since 0.2.6.2 it is adapted to the Pager's firmware 2.0. GPL-3.0-or-later.

The Wi-Fi around your Mac, drawn in the same manner: every network within reach, its band, channel and strength, who shares the air with whom, and how all of it changes over the hour. A native macOS application, for the desk rather than the field. In preparation.

• Passive by design. What can be learnt by listening is learnt by listening.
• Exact rather than impressive. A figure on the screen can always be traced to its source.
• Quiet. No telemetry, no accounts, no calls home.
• Judged on the work. Contributions stand or fall on their merit.

Starchorus is at home in front of a camera. Its demonstration mode shows a convincing sky made of simulated data and placeholder names, and so discloses nothing about anyone: ready for on-set playback and screen graphics in film and television, as it stands.
