Show HN: Self-hosted Raspberry Pi wall display (no cloud, no subscription)

I got tired of subscription-based wall displays and locked ecosystems, so I built my own.

This turns a Raspberry Pi into a wall-mounted dashboard that boots directly into a fullscreen display and runs entirely on the local network. No accounts, no cloud, no ongoing fees.

From a fresh Pi install, it takes about 8 minutes from running the command to a working display after reboot.

Install:

curl -fsSL https://raw.githubusercontent.com/silentg33k/chalkboard-inst... | bash

What it does:

- boots straight into a kiosk display - controlled via a browser on the local network - stores everything locally - runs on nginx + PHP + Chromium kiosk - background updates handled via cron + local scripts

After install it’s immediately usable, and then you can layer in things like schedules, weather, or other content if you want.

I built it specifically to avoid paying for something like a “smart display” that requires a subscription and limits what you can do with it.

Wondering if anyone thinks this solves a problem or is a viable project.

Very nicely done, congrats, but, not a word about the content? What is available to show on such a device? A self-refreshing single URL only? A full-blown Home Assistant client? What does the admin panel provide?
g_33_k•6m ago
Right now it's a structured display rather than just a single URL refresh. Out of the box it handles things like time, schedules, rotating messages, and weather. The layout is driven by JSON and the admin UI lets you define slides, fields, and timing without touching code. There should be screenshots available on the GitHub. It's not trying to be a full Home Assistant frontend — more like a lightweight, purpose-built display that boots straight into something usable. You can extend it pretty easily since it's just PHP + JSON under the hood, but the default goal was: install to immediate working wall display then customize from there. Change numbers of fields per slide. Change whether those fields are static or weekly. Change slide titles. Change un sizes and type settings. Adjust screen timing. Turn slides on or off. Set dimming schedules and reboot, schedules and screen off schedules. Change weather location. Set up remote updating via email and limit email updating to a single email account defined in the settings.

lotza binaries with no actual source code, looks more like a supply-chain attack
g_33_k•11m ago
That's a fair concern.

The installer is doing a full system setup (nginx, PHP, kiosk, etc.), which is why it's packaged as a release artifact instead of a bunch of inline shell.

That said, everything it installs ends up on the Pi in plain files (PHP, JSON, scripts) under /var/www/html/chalkboard, so it's not actually opaque once deployed.

I kept the main repo private while building this out, but I get how that looks from the outside — making the runtime files more directly inspectable is something I should probably clean up.

Appreciate you calling it out.
