Difference between Migic mirror and Pipad

The only difference between Magic mirror and the Pipad is that the Magic mirror use one-way mirror and the Pipad use Toughened Glass.

User Guide

To use the Magic mirror, you can use the pre-configured image which we provide or configure it yourself with the original Raspbian image. It is recommended to install pre-configured images for newbies or first-time installations. The pre-configured images have already installed the required libraries and drivers, and the program runs automatically after booting.

Method 1. Pre-configured image

1. Download the pre-configured image and write it to your SD card.
2. Add the following lines to wpa_supplicat.conf files in the BOOT directory. (if you didn't find the files, create them.)
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=US
 
network={
        ssid="your_real_wifi_ssid"
        psk="your_real_password"
}

Note: you need to change your_real_wifi_ssid and your_real_password" to the real ssid and password.

3. Inset the card to Raspberry Pi and power on it.

Method 2. Configure image manually

1. Write Raspbian image
Download the lasted Raspbian image from the Rasberry Pi website and write it to an empty micro SD card.
Create a new txt file under the BOOT directory of micro SD card and name it as SSH.
Modify config.txt file which is located at BOOT directory, add the following lines to config.txt file
hdmi_group=2
hdmi_mode=82
hdmi_cvt 1920 1080 60 6 0 0 0
Save and insert the micro SD card to Raspberry Pi.
Connect the Magic mirror to network and power on Raspberry Pi.
After booting, you can access Raspberry Pi via SSH, or directly connect keyboard and mouse.
2. Install WM8960 sound card driver
Open the terminal and use the following commands to install
git clone https://github.com/waveshare/WM8960-Audio-HAT
cd WM8960-Audio-HAT
sudo ./install.sh 
Modify config.txt file, remove the following line from the file or comment it.
#dtparam=audio=on
Then reboot Raspberry Pi
sudo reboot
After rebooting, check the driver by the following command
sudo dkms status 
If you can get the information as below, it means that the driver was installed successfully.
wm8960-soundcard, 1.0, 4.19.58-v7l+, armv7l: installed
