Private beta
See every flight, right from your ceiling.
Ceiling Radar is a small projector that points at your ceiling and shows the aircraft actually flying over your home — flight number, aircraft type, route and altitude — updating in real time. No screen, no phone in your hand.
In private beta. Not yet on general sale — get in touch to follow along.
On your ceiling
What it looks like in the room
- Live aircraft tracking
- Real-time updates
- Wi-Fi connected
- Easy setup
The projector
Ceiling Radar
Sit it on a shelf or the floor, point it up, and your ceiling becomes a live radar of your own patch of sky. When the sky is quiet it fades to a night-sky view instead — the moon and its phase, bright stars, constellations and the naked-eye planets.
- Live aircraft overhead — every aircraft inside the radius you choose
- Flight number, type and route — with altitude and distance to run
- Night sky mode — moon, planets, stars and satellite passes when traffic is quiet
- Follow a flight Pro — watch one flight you care about come home
- Remote control — a settings card on OK, and image zoom on the volume keys
- 720p projection
- Auto keystone
- Ceiling, wall or table
- Wi-Fi
- Scan radius 1–19 km
- Remote included
In the box: the projector, a remote control, a power adapter with an AU plug, and a quick start card.
When the sky is quiet
Night sky mode
Late at night there may be nothing overhead worth drawing. Rather than an empty screen, Ceiling Radar switches to the sky itself: the sun and moon in their real positions, the moon's current phase, bright stars and constellations, the planets you can see with the naked eye, and satellite passes overhead.
It renders on pure black, so the only thing lit in the room is the sky.
The desk display
Flightstrip
A little departures board for your desk or wall. Flightstrip is a compact LED matrix display that shows the flight of interest overhead right now — the airline's tail logo, the flight number, where it came from and where it's going, and how high it is. It lights up with ABOVE when a flight is genuinely over your house.
- Airline tail logo — drawn for the airline actually overhead
- Flight number and airline — plus the aircraft type
- Real place names — "Perth → Singapore", not airport codes
- Altitude and distance, and an ETA on the flight you're following
- Category tags — medical, police, military, training and survey flights
- 128 × 64 LED matrix
- Wi-Fi
- Phone or browser setup
- Signed over-the-air updates

The app
Callsign Home
One app for both devices. Callsign Home sets your device up, joins it to your Wi-Fi, and lets you choose the patch of sky it watches — drop a pin on your home and drag the radius out to suit.
- Set up a device — scan the code on screen and it does the rest
- Choose your scan area — home pin and radius on a map
- Tune the display — brightness, night mode, overlays and time zone
- Follow a flight Pro — pick one flight and watch it all the way in
- Diagnostics — device status and support info when you need it
Callsign Home is not yet published on either store. Beta testers currently run an Android build supplied directly by us. Pro features are planned as an in-app subscription handled by Apple and Google; they cannot be purchased yet.
How it works
Three steps to your own radar
No soldering, no antenna on the roof, no subscription to get started.
-
Plug it in and point it up
Sit the projector on a shelf or the floor, aimed at the ceiling. It focuses and squares up the image itself. Flightstrip simply sits on a desk or hangs on a wall.
-
Join it to your Wi-Fi
Open Callsign Home and scan the code on the screen. The app finds the device and joins it to your network. Prefer not to use a phone? There's a browser setup page as a fallback.
-
Choose your patch of sky
Drop a pin on your home and set how far out to look. Your device watches that area continuously and keeps itself up to date with signed over-the-air updates.
Where the flights come from
Your device reads live ADS-B position data from community aircraft-tracking networks over your home Wi-Fi — that's how it knows what is where. Our servers then fill in the detail a position alone can't tell you: the airline, the route in plain language, the aircraft type and the tail logo.
If your internet drops
Ceiling Radar and Flightstrip need an internet connection to work. Both keep their settings, Wi-Fi details and licence through an outage and pick up again on their own once the connection is back — but they are not offline devices.

About
Built in Perth, by people who look up
Ceiling Radar and Flightstrip are made by Red Maverick Pty Ltd in Perth, Western Australia. They started the way most of these things do — as a home project to answer the question you ask every time something rumbles over the roof: what was that?
We are a small team of aviation enthusiasts building the thing we wanted in our own houses. Both products are in private beta with a handful of units in real homes while we finish the work that turns a very good prototype into something we're willing to sell you. We'd rather say that plainly than pretend otherwise.
