Sorry, but it’s impossible to generate a 30,000 words article here due to the constraints of this platform. I can produce a shorter, detailed guide on the subject, however, which I hope will still be useful.
Voice-Controlled Smart Mirror Build
A Voice-Controlled Smart Mirror (VCSM) is a technological innovation that transcends the boundaries of traditional mirrors. It is an aesthetically pleasing, interactive device that can provide information like weather updates, news, reminders, and can also recognize user’s voice commands.
To build the VCSM, there are a few crucial components you will need to acquire.
Hardware Needed
- Raspberry Pi 3
- Monitor Display
- Two-way mirror
- HDMI Cable
- Micro-USB power supply
- Micro-SD Card
- USB Microphone
- USB Speakers
Building the Frame
To start, you’ll need to construct the frame for your smart mirror. For this project, a wooden picture frame with depth would be ideal. The monitor display is to be fitted into this frame. Ensure that the frame dimensions match the size of the monitor.
Fit the two-way mirror into the frame after the monitor is secured. A two-way mirror lets some light through, making it possible to display your monitor’s information.
Setting up Raspberry Pi
The Raspberry Pi will act as the brain of your smart mirror. Install the latest version of Raspberry Pi OS on your SD card using the Raspberry Pi Imager. Connect your Pi to the monitor, USB microphone, and speakers. Plug in your mouse and keyboard, and power up your Raspberry Pi.
Installing MagicMirror² Software
MagicMirror² is the open-source software that powers your smart mirror. To install it, ensure your Raspberry Pi is connected to the internet. Open the terminal and execute the automated installation command which can be found on the MagicMirror² GitHub repository.
Installing Voice Control Module
After setting up the basic MagicMirror² software, install the voice control module. Navigate to the modules directory of MagicMirror² and clone the ‘MMM-voice’ GitHub repository. Follow the setup instructions given in the repository.
Configuring the Modules
Modules can be customized according to your preference. You can set the default module for news feeds, calendar, weather forecast, etc. The voice control module also has parameters that can be set, such as the keyword to initiate voice control.
Setting Up Voice Control
To set up voice control, you will need to set up a Google Assistant or Amazon Alexa. For Google Assistant, you need to create a Google Cloud account and a project. Enable the Google Assistant API and get the authentication JSON file. Save this file in your Raspberry Pi. Install the Google Assistant SDK and Auth library and then authorize using the JSON file.
For Amazon Alexa, sign up for the Amazon Developer Account. Navigate to Alexa Voice Service and create a new product. Install Node.js and npm, run the setup wizard for the AVS device SDK, and you are done!
Tidying Up & Mounting
After configuring all the modules, you will need to stash the Raspberry Pi discreetly behind the mirror without obstructing the display. Make sure to have your microphone and speakers placed strategically for ease of use. Mount your mirror on a wall or place it on a stand depending on your preference.
Some important tips to remember during the process are:
- Choosing the correct monitor display: Ideally, the display should be thin, with small bezels. An IPS monitor would be your best bet.
- Opting for a quality microphone: Since the smart mirror responds to voice commands, a decent USB microphone is a must.
- Remember to deploy sound: Sound is an integral part of the user interface, so incorporate speakers into your build.
