Wall Based Magic Mirror for Current Weather & Time Display
Step 1: Flashing RaspberriPi Hard Disk / Install Required Software (Using Ubuntu Linux)
Magic Mirror: Page 1
Download "RASPBIAN JESSIE LITE"https://www.raspberrypi.org/downloads/raspbian/
Create your new hard disk for DashboardPI
Insert the microSD to your computer via USB adapterand create the disk image using the dd command
Locate your inserted microSD card via the df -h
Magic Mirror: Page 2
command, unmount it and create the disk image withthe disk copy dd command
$ df -h /dev/sdb1 7.4G 32K 7.4G 1%/media/XXX/1234-5678
$ umount /dev/sdb1
Caution: be sure the command is completelyaccurate, you can damage other disks with thiscommand
if=location of RASPBIAN JESSIE LITE image fileof=location of your microSD card
$ sudo dd bs=4M if=/path/to/raspbian-jessie-lite.imgof=/dev/sdb (note: in this case, it's /dev/sdb,/dev/sdb1 was an existing factory partition on themicroSD) Setting up your RaspberriPi
Insert your new microSD card to the raspberrypi andpower it on with a monitor connected to the HDMIport
Login
user: pi pass: raspberry
Change your account password for security
sudo passwd pi
Enable RaspberriPi Advanced Options
sudo raspi-config
Choose: 1 Expand File System
9 Advanced Options
A2 Hostname change it to "MagicMirror"
A4 SSH Enable SSH Server
A7 I2C Enable i2c interface Enable the English/USKeyboard
sudo nano /etc/default/keyboard Change the followingline: XKBLAYOUT="us" Reboot PI for Keyboard
layout changes / file system resizing to take effect
$ sudo shutdown -r now Auto-Connect to your WiFi
sudo nano /etc/wpa_supplicant/wpa_supplicant.confAdd the following lines to have your raspberrypiautomatically connect to your home WiFi (if yourwireless network is named "linksys" for example, inthe following example)
network={ ssid="linksys" psk="WIRELESSPASSWORD HERE" }
Reboot PI to connect to WiFi network
$ sudo shutdown -r now
Now that your PI is finally on the local network, youcan login remotely to it via SSH. But first you need toget the IP address it currently has.
$ ifconfig Look for "inet addr: 192.168.XXX.XXX" inthe following command's output for your PI's IPAddress Go to another machine and login to yourraspberrypi via ssh
$ ssh [email protected] Start Installing requiredpackages
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install vim git python-smbus i2c-toolspython-imaging python-smbus build-essential python-dev rpi.gpio python3 python3-pip libi2c-dev python-requests Update local timezone settings
$ sudo dpkg-reconfigure tzdata select your timezoneusing the interface Setup the simple directory lcommand [optional]
$ vi ~/.bashrc
add the following line:
$ alias l='ls -lh'
$ source ~/.bashrc
Magic Mirror: Page 3
Fix VIM default syntax highlighting [optional]
$ sudo vi /etc/vim/vimrc
uncomment the following line:
syntax on DHT11 Install
$ cd ~
$ git clonehttps://github.com/adafruit/Adafruit_Python_DHT.g...
$ cd Adafruit_Python_DHT/
$ sudo python setup.py install
$ sudo python ez_setup.py
$ cd examples/
$ vi simpletest.py
Change the following line:
sensor = Adafruit_DHT.DHT11 Comment the line out
pin = 'P8_11' Uncomment the line and change the pinnumber to 16
pin = 16 Run the test
python simpletest.py
You should see a metric reading of Temp andHumidity displayed on the command line.
Step 2: Supplies Needed: 12" X 24" Acrylic See-Through Mirror, 3mm
Step 3: Supplies Needed: Balsa Wood Strips 0.125 X 0.5 Inches
Magic Mirror: Page 4
Step 4: Supplies Needed: 12x24 Inch Black Picture Frame
Step 5: Supplies Needed: OLD Android Tablets (x2)
Magic Mirror: Page 5
Step 6: Supplies Needed: DHT11 Humidistat
Step 7: Supplies Needed: RaspberriPi Zero (or Regular RaspberriPi Should Work)
Step 8: Build and Wire the Device
DHT11 Humidistat
VCC -> 5V
GND -> GND
DATA -> GPIO 16 / PIN 36
Magic Mirror: Page 6
Step 9: 3D Print Brackets
In the /construction folder of the project 3D print the following attachments to build the picture frame borders andtablet holders.
Print the Following Tablet Holders:
tablet-mounts.stl
Print the Following Frame Corner blocks and balsa wood attachments:
mirror-corner-blocks.stl
mirror-corners.stl
mirror-sides.stl
Magic Mirror: Page 7
Step 10: Assembly
Gather together the frame balsa wood strips and the 3D printed attachments
Magic Mirror: Page 8
Step 11: Assembly (cont.)
Assemble the balsawood strips inside the corner brackets (sliding the balsawood through the side brackets, makesure they're square against the corners of the picture frame. Paint everything black with spray paint.
Magic Mirror: Page 9
Step 12: Assembly (cont.)
Screw the corners to the 4 corner blocks to hold the frame together.
Step 13: Assembly (cont.)
Attach the tablets and Raspberry PiZero to the wood to eventually fix to the wall.
Magic Mirror: Page 10
Step 14: Assembly (cont.)
Attach to the wall the board. (Note the 2 screws on the top left and right, they will be used to hold up the pictureframe with frame border attached to place in front of the tablets to shine through the mirror)
Magic Mirror: Page 11
Step 15: Finish Assembly
Finally replace the cardboard piece inside the picture frame with a two way mirror and on each corner of thepicture frame screw into the corner (3D printed) blocks to hold the picture frame to the frame border.

Step 16: Software Required
Create the Device Hub Project hosted on a PHPenabled webhost of your choice for the top tabletto get data
https://github.com/khinds10/DeviceHub
Create Weather Tablet Project for the bottomtablet
https://github.com/khinds10/WeatherTablet
Setup Startup Scripts, Temp Logger to API scripteach 3 minutes
In the raspberrypi folder of the project copy thesettings.shadown.py file to settings.py with the hostfile of the DeviceHub project above you have setup.
$ crontab -e Add the following lines:
*/3 * * * * python/home/pi//MagicMirror/raspberrypi/temp-check.py
Verify the display starts working on reboot
$ sudo reboot
Create the tablet clock website
Create a PHP enabled website online with thecontents of the "tablet" folder in this project.
Configure the website: In the "tablet/server" folder ofthe project, copy the config.shadow.php file to a filenamed "config.php" Edit the "config.php" configurethe $deviceHubAPI value to point to the device hub ofyour choosing from the referenced project above(https://github.com/khinds10/DeviceHub)
Example Apache2 Configuration File for the tabletclock PHP website
