Smart Mirror

Installation

You will need:

• Java 8
• npm (which is installed with node.js)

Running the application

Run the following:

1. npm install -g bower
2. bower install
3. ./gradlew run

The application should now be on http://localhost:9098

Installing on RaspberryPi

./src/main/deploy gives you a rough idea of where files should go for a deployment to a RaspberryPi:

• Init script must be copied to /etc/init.d/smart-mirror (and give it the correct permissions -> 0755)
• YAML configuration should be copied to /etc/smart-mirror.yml
• Application should be copied to /opt/smart-mirror/smart-mirror.jar

Now you can execute sudo service smart-mirror start and the app will spin up

I want smart-mirror to start on boot!

sudo update-rc.d smart-mirror defaults

Where can i find logs?

Logs can be found at /var/log/smart-mirror.log and /var/log/smart-mirror.err

Does smart-mirror automagically update itself?

Yes...ish

I use SnapCI as my automated build pipeline. It picks up code changed from GitHub, runs the tests and generates build artifact on completion. I've written a small bash script which polls the SnapCI API to update the JAR if there are any changes

• Copy get_latest.sh script to ``/opt/smart-mirror/get_latesh.sh`
• Execute sudo crontab -e
• Add */5 * * * * /opt/smart-mirror/get_latest.sh {username} {api_key} >> /var/log/smart-mirror.cron.log 2>&1

I want smart-mirror to turn on/off depending on the time of day!

You're in luck!

• Copy the turn_on_screen.sh and turn_off_screen.sh to /opt/smart-mirror/
• Execute sudo crontab -e
• Add 0 7 * * * /opt/smart-mirror/turn_on_screen.sh >> /var/log/screen.cron.log 2>&1 to turn on at 7am
• Add 30 8 * * * /opt/smart-mirror/turn_off_screen.sh >> /var/log/screen.cron.log 2>&1 to turn off at 8.30am

Awesome, my screen turns itself off! But how can i turn it back on manually?

Open ~/.config/openbox/lxde-rc.xml and add the following to the <keyboard> section

<keybind key=”A-C-S-1″>
  <action name=”Execute>
    <command>/opt/smart-mirror/turn_on_screen.sh</command>
  </action>
</keybind>
<keybind key=”A-C-S-0″>
  <action name=”Execute>
    <command>/opt/smart-mirror/turn_off_screen.sh</command>
  </action>
</keybind>

Unlike crontab which runs as root, this will run as your user, so you'll need to ensure we can execute a few executables as your user

chmod u+s /opt/vc/bin/tvservice
chmod u+s /bin/chvt

Now You can turn your screen off with Alt-Control-Shift-1 and off with Alt-Control-Shift-0

My screensaver blanks the screen :-(

apt-get install x11-xserver-utils

Edit /etc/xdg/lxsession/LXDE-pi/autostart and add these three lines

@xset s off
@xset -dpms
@xset s noblank

Log out, log in, verify it's working with

xset -q

The screen resolution looks off!
