Use cases
Six things you can build in an afternoon
None of these needed a developer. Each one is a prompt, a Raspberry Pi, and whatever screen was already on the wall.
The gallery
Five screens and one speaker. Same board, same agent, same afternoon — the difference between them is the wording of the prompt.

Weather screen
“A screen with the forecast for Prague, large colourful icons, today and three days ahead.” That sentence is the entire project. It ends up in the hallway, where people glance at it on the way out instead of unlocking a phone — and where a phone would have shown them three notifications first.

Photo frame
Point the project at a folder of pictures and the screen cycles through them. Full bleed, no clock in the corner, no logo, no notification sliding up from the bottom. Change the folder and every frame you own changes with it, without anyone touching the device.

Restaurant menu
Today's dishes on a screen by the door or above the counter. Someone in the kitchen edits the text, presses publish, and the screen follows within a minute — no printer, no laminator, no crossing out the soup with a marker.

Podcast player
An RSS feed, three large controls and nothing else. No account, no app, no algorithm deciding what plays next. Add a small add-on board with real buttons and the controls become physical, which is the difference between a device someone uses and one someone ignores.

Guest information screen
Wi-Fi name and password, breakfast hours, check-out time, the door code, today's weather. The questions a small guesthouse answers thirty times a week, answered once and left on the wall. Each device pulls its own project, so every room can differ.

What's on in town
The screen in the hall that answers “is anything happening tonight?” — concerts, markets, the castle's opening hours, three at a time in letters you can read from across the room. It pulls the town's event feed and drops whatever is already over, which is the only reason a board like this is still right in March.
What they have in common
All six run on the same hardware and the same agent. The difference between a photo frame and a weather screen is a prompt, not a product line — and swapping one for the other means selecting a different project in the dashboard, not visiting the device.
Not every project has to draw anything, either. A device with no display can read a sensor and log it to the dashboard, and nothing about the setup changes: it is the same agent doing less.
Publish a new version and every device running that project picks it up on its own. Nothing calls in to the Pi; the Pi only ever calls out.
Your Pi could be doing one of these tonight
Describe what the screen should show. The device does the rest.
