Introduction

If you follow the SparkFun Blog, you may have seen my post about my attempts to keep up with my family's ever changing schedule. With schooling and summer camps going online and both myself and my partner working from home... there's just too many virtual meetings to keep up with. An offhand comment about needing a "battle station" led to the Magic Mirror project.

Magic Mirror

This tutorial presumes you have some basic familiarity with Unix systems and commands. It's not required, but is certainly helpful. Let's dive in and see how to set this up, shall we?

Installing Magic Mirror

If you've followed along with the Raspberry Pi 4 Kit Hookup Guide, you should have a functioning Raspberry Pi desktop in front of you. Now we can move on to the "magic"!

Installing Magic Mirror

The basic installation is relatively straight forward. We'll run through the steps here, but you can also head over to the Magic Mirror Installation & Usage tutorial and follow their steps.

Magic Mirror Documentation: Manual Installation

Install NodeSource

We first need to install NodeSource. Open a terminal window on your Raspberry Pi desktop. Then copy and paste the following code:

language:shell
curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -

If all goes well, you should see something like the following:

Install NodeJS

The next thing we need is NodeJS. Copy and paste the code below into your terminal window:

language:shell
sudo apt install -y nodejs

Clone the MagicMirror GitHub Repo

Now we get to the good part! Let's clone the MagicMirror GitHub repo to our Raspberry Pi. Copy and paste this code to your terminal and watch the GitHub clone magic happen....

language:shell
git clone https://github.com/MichMich/MagicMirror

Step3-Cloning the Git Repo

Away we go!

Step3-Cloning the Git Repo Complete

Install Magic Mirror

We're close! Go ahead and cd (change dir) into the MagicMirror directory:

language:shell
cd MagicMirror

And then we type in the following:

language:shell
npm install

Step4-Install Magic Mirror

Copy the Sample Config File

So close! Let's copy the sample config file into one we can play around with:

language:shell
cp config/config.js.sample config/config.js

Step5-Copy Config Sample

Run the Sample Config

Okay! Let's make this magic!

language:shell
npm start

Default Magic Mirror



config.js

This file is essentially the brains of the operation. This is where you layout how you want your Magic Mirror to look. You can add modules, delete modules, move modules, and customize to your heart's content.

Navigate to your /home/pi/MagicMirror/config directory and open up config.js in Geany (right click and select Geany).

We're going to skip over most of the setup code. That said, let's look at one little bit here - scroll down until you see the outlined bit below:

Outlined settings for language, time format, and units

Click the image for a closer look.

Outlined in the image are the following settings:

Scroll a little further down and you'll find the modules section:

modules section of config.js

Click the image for a closer look.

Hopefully, this section is also fairly straight forward. You'll notice that for each module:, you'll need the position: you'd like it to be on the screen. Possible values are:

If you put multiple modules in the same position, they will be shown in the order they are listed in the config file.

Moving the Clock

Remember the initial Magic Mirror image above?

Default Magic Mirror screen

Let's move that clock from the top left to the top right!

Find the following in your config file:

Clock module in the config file - top left

Click the image for a closer look.

Change top_left to top_right:

Clock module in the config file - top right

Click the image for a closer look.

Save the config file, go back to your terminal window, and start up Magic Mirror (npm start) aaaaaaand...

Magic Mirror with the clock at top right

VOILA! Easy peasy, right? Each module has its own default requirements and in the default config.js file, these requirements are set up for us. We'll look at some more customization in subsequent sections.

Customizing The Modules - Compliments

Sooo... one of the first compliments that popped up on my brand new magic mirror was "Hey there sexy!". Not sure about y'all but that made me slightly uncomfortable. Especially when my kids started repeating it to random strangers walking by. No bueno. Let's start by looking at the Compliments module and editing those compliments to be a bit more to our (my) liking.

CD to your MagicMirror/modules/default/compliments directory on the Pi. Open up compliments.js in either Geany or your text editor of choice. You should see something like the following:

Default compliments

Click the image for a closer look.

See all those weird compliments in there? Yeah. Let's change those. This file is pretty straight forward javascript - you can go ahead and change the text of those compliments; just make sure you leave the syntax intact. This is looking better....

Updated compliments

Save your file and head on back to the terminal window. Make sure you are in your MagicMirror folder and type in npm start. Voila!

Feelin' pretty shiny right about now.



Customizing The Modules - Using Your Google Calendar

One of the primary reasons I wanted a Magic Mirror was to keep track of everyone's calendars. Let's change our calendar module to reflect our Google calendars instead of holidays.

In config.js, navigate to the calendar module.

Highlight of calendar module

Click the image for a larger view.

See where it says url? That's what you'll need to change. You may want to change the header as well.

Finding Your Calendar Link

From your google calendar, navigate to the Settings and Sharing option on the calendar you want to use. Click on the three little dots next to the calendar to get to the link!

Google Calendar Settings and Sharing Link Location

Click on that link! Once you're in Settings and Sharing, scroll down until you see the following:

Google Calendar iCal addresses

Click the image for a closer look.

You'll notice that there is a Public Address and a Secret Address. If your calendar is public, go ahead and use that address. However, if you want to keep your calendar private to the world at large, go ahead and use the secret address in iCal format. Copy that link!

Now head on back to the config.js file and paste that iCal link (secret or public) into the url location.

Save your config.js file, head back to the terminal window, and type in npm start to see your changes in the Magic Mirror!

There are plenty of third party modules that can customize the look of your calendars. Take a peek here. Almost all of the modules have their requirements either listed out or an example is shown. Give it a try!

Customizing The Modules - Adding New Modules

Now that we have THAT out of the way, let's look at other modules we can edit or add.

By default, the Magic Mirror comes with the following modules:

The default config.js file that we copied in the Installing Magic Mirror section has the basics set up for us. But what if we want more? Well, we're in luck. There's a whole ecosystem of third party modules you can add into your Magic Mirror.

Word of the Day

Let's do something simple - let's add the Word of the Day.

Word of the Day GitHub Repo

Start by opening a terminal window on your Raspberry Pi and navigating to your MagicMirror's modules folder. If you are using the default installation directory, use the command:

language:shell
cd ~/MagicMirror/modules

Clone the module:

language:shell
git clone https://github.com/bittiez/MMM-MWWordOfTheDay.git

You should see something along the lines of the following:

git clone word of the day module

Once you have the module code, head back to your config.js file and add the following:

language:javascript
module: 'MMM-MWWordOfTheDay',
    position: 'top_right',
    config: {
        updateInterval: 120000,
        headerText: "Word of the day"
}

Adding word of the day module to config.js

Click the image for a closer look.

Save and quit! From your terminal, type npm start and you'll see your word of the day in the upper right hand corner!

Finishing Touches

There are so many options when making the box and the mirror. Googling "Magic Mirror Frame" is a little bonkers. I went with a shadow box I got on sale from Michaels, and some outdoor reflective film I bought from Amazon. I also had to get some right angle HDMI adapters so that the cable would lay somewhat flat and fit into the frame.

Magic Mirror Main view

Since the frame was bigger than the screen, I had to do some finagling to get the screen to fit where I wanted it to.

Mounting the screen in the frame

Making It Better

The Raspberry Pi 4 runs hot enough that I bought the Heatsink Case. I still needed to drill a few extra holes on the top of the mirror frame to provide enough ventilation but it's worth it to have the possibility of future expansion.

When time permits, I'll likely add a safe reboot and shutdown button with the Qwiic PHat like Bobby does here:

Raspberry Pi Safe Reboot and Shutdown Button

April 20, 2020

Safely reboot or shutdown your Raspberry Pi to avoid corrupting the microSD card using the built-in general purpose button on the Qwiic pHAT v2.0!

I may also use the Qwiic PHat to extend the Qwiic ecosystem. It'd be nice to add a proximity sensor such that it's not just on all the time. As you can see in the images above, I've already used css to customize our calendars and added Google Tasks in. Super handy to know what you need to do each day!

Troubleshooting

The MagicMirror project has a wonderful forum of users ready and willing to help out! I have popped over there a few times to sort out some CSS configuration questions myself.
