THE WALL, a 128 by 64 LED matrix display

An LED panel on your shelf that shows the aircraft overhead. Plus the time, the weather, your notes, whatever you send it.

What the panel shows

Every picture is a real answer from the server, drawn with the same code as the preview on the device page. The departures are those at Luxembourg's main station, the weather is today's in Luxembourg City. Only the logo is a colour block here, and the track with its cover is made up.

Nine modes

Switch any time from the web, no reflashing

Flight radar

The nearest aircraft in your radius, five views: route, departure and arrival, what it is flying over, the numbers, a map. In the units you pick.

Track one flight

Flight number, callsign or registration, anywhere in the world: what it is flying over, when it left, when it lands. Shows up once a receiver can see it.

Departures

CFL, RGTR, AVL, Luxtram, TICE. Up to three stops, picked on a map of the whole country. The number is the real time, a delay turns it amber.

Clock and date

Fonts, colours, seconds, 12 or 24 hour, dimmer after sunset. Runs from the clock chip on the board, even without Wi-Fi.

Weather

As a strip under the clock, or full screen with three days ahead. Celsius or Fahrenheit, wind if you like.

Notes

Type it, it shows up on the wall. Two lines of 21 characters, a new note flashes three times. People you share the device with may write too.

Now playing

What plays in your own Spotify account: cover, title, artist and album, with a time bar the panel counts on its own. Four layouts, and the next track is announced ten seconds before the end.

Countdown

A name and a date. It counts the days in your time zone, says TODAY on the day, and with a time it counts the last hour down to the second.

Ticker

Up to 200 characters scrolling across, three speeds, in the colour you pick. The clock and date stay above it if you like.

Your idea

Modes are built on the server, not in the firmware. New ones cost no flash, and with the source open you can add your own.

Beyond the modes

What applies to the whole panel, whichever mode is showing.

TIMERS AND ALARM: Up to five timers, started on the website or from Home Assistant. A running one shows its time left in a corner of every mode. One alarm per device, with time and weekdays.
ROTATION: Flight, clock, weather, departures, Spotify, countdown and ticker take turns, each for 10 seconds to 10 minutes. Spotify only while music plays, the countdown until a month after its date, the ticker with text.
EMPTY SKY: When nothing flies, the panel shows the clock, a waiting animation or a quiet resting screen. You pick which.
NIGHT: Brightness is set on the website and can drop to 35 percent of it between sunset and sunrise. One switch stops all motion on the panel.
SHARING: Share a device by email, with edit rights or view-only. Guests may send notes and nothing else.
HOME ASSISTANT: The panel as a light, the mode as a select, notes as notifications, timers and the alarm as entities. Pairing takes a six-character code from the panel.

Three steps, then it runs

01

Plug it in, join its Wi-Fi

The panel shows the name of its own network, THE WALL SETUP, and the password for it. Join it with your phone and the setup page usually opens by itself. Pick your home Wi-Fi there, 2.4 GHz.
02

Paste the key

Your account hands you an API key. Paste it into the same setup page, that is what pairs the two. The panel says HELLO with your name.
03

Run it from anywhere

Modes, rotation, brightness, night dimming, firmware updates over the air. A change reaches the panel in about two seconds. It only needs power and Wi-Fi.

Nothing soldered

Two parts that plug together, plus two printed feet the board snaps onto. A phone charger runs the whole thing. Firmware and server are on GitHub.
