A Pimoroni Inky Impression 13.3" (Spectra 6) mirroring the live collage. A Pi screenshots the site, mats it onto an A5 opening, and pushes to the panel, refreshing only when the birds change. Build one of your own at theodore.net/projects/AvianVisitors#frame-ous.

1. Flash the SD card

Flash an sd card with Raspberry Pi OS Lite (64-bit) via Raspberry Pi Imager. In the customisation dialog set:

Username
WiFi SSID + password
Hostname: birdpic
Enable SSH with password auth

Then install in Pi and power up.

2. Run the installer

ssh <your-username>@birdpic.local
git clone https://github.com/Twarner491/AvianVisitors
cd AvianVisitors/frame && ./install.sh

Enables SPI + I2C, installs the deps and a 15-minute systemd timer, writes ~/.birdframe/config.toml, and reboots once to bring SPI up.

3. Point it at the collage

After it reboots and comes back, set your image source in ~/.birdframe/config.toml. The Pi is too small to run a browser, so it fetches a ready-made PNG that the aggregator Worker renders at /frame.png, gated by a key:

base_url  = "https://bird.onethreenine.net"
image_url = "https://bird.onethreenine.net/frame.png?k=YOUR_FRAME_KEY"

No Worker? Set shoot = true to screenshot on any capable host instead. Full options are in config.example.toml.
