MagicMirrorOS

An out of the box Raspberry Pi Raspbian distro that lets you run MagicMirror to make an interactive mirror.

Where to get it?

Download directly from here

Variants for arm 32-bit (armhf in image name) and arm 64-bit (arm64 in image name) are available.

How to use it?

1. Use the Raspberry Pi Imager to install the zipped image to an SD card
2. Use the customization settings of the Raspberry Pi Imager for WiFi, hostname and user settings
3. Boot the Pi from the SD card
4. With the first start the docker images are pulled which takes some time, you can follow this process by executing journalctl --user -f
5. You can change the settings of the MagicMirror in the files located at /opt/mm/mounts/

Docker

Under the hood MagicMirrorOS uses this docker setup.

You find the docker setup at /opt/mm/ on your raspberrypi. For more information about this setup, how you can start/stop the docker container, how to see the logs , ..., please refer to the documentation provided there.

Requirements

• 2A power supply
• Pi Zero2w, 2, 3, 4 & 5. The Raspberry Pi 0/1 is currently not supported.

Features

• Runs MagicMirror out-of-the-box

Developing

Requirements

1. Docker or Vagrant, docker recommended
2. Docker Compose Plugin - recommended if using docker build method, instructions assume you have it
3. Downloaded Raspbian Lite image.
4. Root privileges for chroot
5. Bash
6. sudo (the script itself calls it, running as root without sudo won't work)

Build MagicMirrorOS

MagicMirrorOS can be built using docker running either on an intel or RaspberryPi (supported ones listed). Build requires about 4.5 GB of free space available.

MagicMirrorOS supports building variants, this setup contains 2 variants for the 2 architectures, armhf and arm64.

You can build it assuming you already have docker and the docker compose plugin installed issuing the following commands:

variant="armhf"
git clone https://github.com/guysoft/MagicMirrorOS.git
cd MagicMirrorOS/src/image
wget -c --trust-server-names 'https://downloads.raspberrypi.org/raspios_${variant}_latest'
cd ..
sudo docker compose up -d
sudo docker exec -it magicmirroros-build build $variant

Building Using Vagrant

There is a vagrant machine configuration to let build MagicMirrorOS in case your build environment behaves differently. Unless you do extra configuration, vagrant must run as root to have nfs folder sync working.

To use it:

sudo apt-get install vagrant nfs-kernel-server
sudo vagrant plugin install vagrant-nfs_guest
sudo modprobe nfs
cd MagicMirrorOS/src/vagrant
sudo vagrant up

After provisioning the machine, its also possible to run a nightly build which updates from devel using:

cd MagicMirrorOS/src/vagrant
run_vagrant_build.sh [Variant]

Usage

1. If needed, override existing config settings by creating a new file src/config.local. You can override all settings found in src/config. If you need to override the path to the Raspbian image to use for building MagicMirrorOS, override the path to be used in ZIP_IMG. By default, the most recent file matching *-raspbian.zip found in src/image will be used.
2. Run src/build_dist as root.
3. The final image will be created in src/workspace

Customization

Rotating the output

• Option 1

  • Edit the file /opt/mm/run/.env and add e.g. the following line RANDR_PARAMS="--output HDMI-A-1 --transform 180" to rotate the output by 180 degrees, or RANDR_PARAMS="--output HDMI-A-1 --transform 90" to rotate the output by 90 degrees, to see all possible options login to the container with docker exec -it labwc bash and then you can look at all the options available with wlr-randr --help. To get the parameter for --output you can call wlr-randr, you find the parameter in the first line (in this example HDMI-A-1).
  • Restart the docker container by executing docker compose up in directory /opt/mm/run.

  If you need to change the delay for the wlr-randr options to be applied, e.g. if the display is rotated when MagicMirror is starting, it can result in a black screen. To avoid this, increase the delay (on slow systems e.g. pi < v4 you have to increase this up to 80s).

  • Edit the file /opt/mm/run/.env and add e.g. the following line RANDR_DELAY=10s to apply the wlr-randr options after 10 seconds, the default value is 5s.
  • Restart the docker container by executing docker compose up in directory /opt/mm/run.

• Option 2

  You can use css for rotating. Edit the file /opt/mm/mounts/css/custom.css and the following lines. You can use 90deg or -90deg.

  body {
    margin: 0;
    position: absolute;
    transform: rotate(90deg);
    transform-origin: bottom left;
    width: 100vh;
    height: 100vw;
    object-fit: cover;
    top: -100vw;
    visibility: visible;
  }

Changing timezone

The setup tries to set the timezone automatically, if you need to change your local timezone:

• Find your timezone in the "TZ database name" column on Wikipedia

• nano /opt/mm/run/compose.yaml and add:

        environment:
          TZ: <your timezone>

• Restart the docker container by executing docker compose up in directory /opt/mm/run.
