3 tries 3 fails Raspberry b+

Does everything install correctly?

What do you mean you can’t get it to start? What happens?

I’ve followed the guide from
http://blog.dylanjpierce.com/raspberrypi/magicmirror/tutorial/2015/12/27/build-a-magic-mirror.html

And

http://michaelteeuw.nl/post/83916869600/magic-mirror-part-vi-production-of-the

And neither work I’m afraid. No error messages, nothing notes a file/programme missing, nada. Just get to the point where it should “work” and nothing happens.

I’ll try the pi 0 tutorial and see how that goes. It’s just that I have a spare pi b and all parts, and it’s a shame I can’t get it to go…

@infamoustiggr Well that’s because you need to do this way…

https://github.com/MichMich/MagicMirror

The instructions are in full and easy to follow there ;) The other places may not be up-to-date. The instructions in the link above are for this mirror exactly …

There’s two ways:
Automatic Installer (Raspberry Pi Only!)
or
Manual Installation

@infamoustiggr

Yup, cowboydude is absolutely right. I went with the Automatic installer on my Raspberry Pi 3

Worked perfectly, and the directions are damn good

infamoustiggr

I know, but I’ve got a Pi 1 model b. Unfortunately the easy install option is unavailable…

I’ve got as far as the npm install, but it’s throwing up lots of error in a log file… Any hints?

This is from the main installation page at https://github.com/MichMich/MagicMirror#manual-installation

Raspberry Pi Support

Electron, the app wrapper around MagicMirror², only supports the Raspberry Pi 2 & 3. The Raspberry Pi 1 is currently not supported. If you want to run this on a Raspberry Pi 1, use the server only feature and setup a fullscreen browser yourself.

Server Only:

In some cases, you want to start the application without an actual app window. In this case, execute the following command from the MagicMirror folder: node serveronly. This will start the server, after which you can open the application in your browser of choice.

I hope this helps

@Mykle1 ho there! I had read this bit too, but, being as I am to programming what a brick is to top flight springboard diving, I’m getting stuck on what parts of the instructions apply to me and which don’t. For example, the npm install comes up with a horrific number of errors, but I don’t know if I actually need it…

Once I’ve got this working I’ll write it up… I’m sure there’s a while bunch of people who bought the Pi 1 b and have since upgraded!

Hi all,
I’m running my mirror on an original Pi B 256MB with no issues at all!

The Raspbian version I use is DietPi which is really great on a 256MB Pi. Note that the standard user in DietPi is “root” rather than “pi”. If you use standard Raspbian just replace all occurences of “root” with “pi” in the scripts below.

As the documentation states you start off with installing the Server Only option. If I remember correctly I had to manually install many of the node module dependencies as they weren’t installed correctly otherwise

I use matchbox as the window manager because it suited my needs best. It uses less resources which again is great for a 256MB Pi.

I’m using systemd scripts rather than pm2 as I think they work better. My scripts:

magicmirror.service:

[Unit]
Description=Node.js Magic Mirror Server

[Service]
ExecStart=/usr/bin/node /root/MagicMirror/serveronly/index.js
WorkingDirectory=/root/MagicMirror
Restart=always
RestartSec=20
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=nodejs-magicmirror
Environment=NODE_ENV=production PORT=1337

[Install]
WantedBy=multi-user.target

matchbox.service:

[Unit]
Description=X11
After=X.service

[Service]
Environment=DISPLAY=:0.0
ExecStart=/usr/bin/matchbox-window-manager -use_titlebar no -use_cursor no
User=root
Restart=on-failure

[Install]
WantedBy=multi-user.target

Kioskbrowser.service:

[Unit]
Description=Kiosk Browser
After=matchbox.service magicmirror.service
Requires=magicmirror.service

[Service]
WorkingDirectory=/root/MagicMirror
User=root

Environment=DISPLAY=:0.0

# Don't activate screensaver
ExecStartPre=/usr/bin/xset s off

# Disable DPMS (Energy Star) features
ExecStartPre=/usr/bin/xset -dpms

# Don't blank the video device
ExecStartPre=/usr/bin/xset s noblank

ExecStart=/root/kioskbrowser http://localhost
Restart=on-failure

[Install]
WantedBy=multi-user.target

Note that the kioskbrowser service relies on a user script called /root/kioskbrowser. This script has some extra logic to avoid the initial white screen when midori has loaded but not fetched any magic mirror content. The script perform a curl call to see if the magic mirror module is responding. If not it waits for a few seconds and then tries again. Once the magic mirror responds it starts midori in fullscreen mode.

/root/kioskbrowser:

#!/bin/bash
status=1
url="$1"
wait="10s"
tries=0

# URL must be first argument
if [ -z "$url" ]; then
  exit 1
fi

# Make sure that the url is reachable
while [ $status -ne 0 ]; do
  let tries++
  curl --fail --progress-bar -o /dev/null --url "$url"
  status=$?
  if (($tries > 10)); then
    wait="30s"
  fi
  if (($tries > 20)); then
  wait="5m"
  fi
  if (($tries > 30)); then
  echo "$0: Can't load URL $url"
    exit 2
  fi
  sleep "$wait"
done

# Start browser in fullscreen mode
/usr/bin/midori -e Fullscreen -a "$url"

Hope this helps.

Hi Alvinger,
That sounds exactly what I need thanks, with the only problem being that, being a complete learner, I don’t know what to do with it…

Do I need to put the scripts into a particular file or just write them into the command line itself?

On the whole I’ve managed most projects independently thanks to the mighty google and suitable search terms, got my media centre and a pi in my van as a music/film hub, but this is the first thing that’s been a bit more complicated and I’ve failed miserably to this point…

I’ve been trying to learn this sort of thing for years and just never seem to have the time. I’m a physio by trade, so I don’t even have something close to this as my day job.

Thanks for your patience!

Nick

@infamoustiggr,

Installed packages
If you are running dietpi or Raspbian Jessie systemd should already be installed. Otherwise you need to install and enable it. Google is your friend.

Midori should also be installed but Matchbox most likely isn’t. Install it with:

sudo apt-get install matchbox-window-manager

Systemd
The systemd scripts are all located in /etc/systemd/system. To create magicmirror.service enter the following command (I’m using the editor nano):

sudo nano /etc/systemd/system/magicmirror.service

Paste script from above and edit to suit your needs.

Make the script executable with the following command:

sudo chmod +x /etc/systemd/system/magicmirror.service

Repeat these steps for the other scripts by replacing magicmirror.service with the appropriate name.

Custom script
For DietPi the scripts are located in /root and for Raspbian they are located in /home/pi. Change to the appropriate directory with cd.

nano kioskbrowser

Paste the code from above and save/exit
Make the script executable by running:

chmod +x kioskbrowser

MagicMirror config
Make sure that MagicMirror has the correct port set in config.js. (Look for “port”: in config/config.js and make sure it is set to 80. Otherwise modify kioskbrowser.service and change the url http://localhost to http://localhost:port where port is the port number of MagicMirror.)

Scheduled on/off times
If you’re like me and do not want your mirror active during the night you can either use a module such as MMM-ModuleScheduler or a cron script that turns the monitor power on/off at set times. I use the latter. To do that you enter the command:

crontab -e

and paste the following lines

59 05 * * *     /usr/bin/vcgencmd display_power 1
09 23 * * *     /usr/bin/vcgencmd display_power 0

Exit and save.
The first line turns the monitor ON at 05:59 and the second line turns if OFF at 23:09. Modify according to needs.

Reboot your pi and enjoy!
