Smart mirrors are a fantastic addition to today’s innovative home, offering a blend of technology and convenience that can revolutionize your daily routines. Embracing the potential of voice-activated home assistants, this article walks you through creating your own voice-activated smart mirror.
The primary ingredient for your smart mirror is a two-way mirror. This specialized type of mirror allows light to pass through, effectively acting as an ordinary mirror until a display screen behind it illuminates. Reputable online retailers like Amazon and numerous specialized online stores offer two-way mirrors specifically made for this application.
A monitor or an old flat-screen TV will provide the display. Devices that have HDMI capability are recommended, preferably with fairly thin bezels to maintain the sleek look of your smart mirror. For smaller smart mirror projects, a tablet could suffice.
The brain running your smart mirror operation can be a Raspberry Pi, a low-cost, high-performance mini-computer loved by DIY enthusiasts. It’s capable of running full operating systems and displaying web contents, making it excellent for this task. Alternatively, for a more easy plug-and-play solution, Amazon Fire Stick or Google Chromecast can also be used.
Raspberry Pi requires a MicroSD card to function as its hard drive. A minimum 8 GB card is recommended, which allows for the installation of the open-source MagicMirror² software that forms the backbone of the smart mirror interface.
To add voice activation to your smart mirror, inexpensive and high-quality microphones like the USB Mini Mic or the PlayStation Eye can be easily plugged into the Raspberry Pi. Meanwhile, speakers can be anything from a simple USB speaker to a comprehensive sound bar.
Once you’ve gathered all of these pieces, it’s time to assemble your smart mirror.
Firstly, you’ll need to prepare the two-way mirror. The size of the mirror should ideally just be slightly larger than the monitor or TV screen. This will allow extra room for the Raspberry Pi and wiring.
Once it’s cut to size, you can attach it directly to the display using mirror adhesive which is safe for electronics. Some prefer to create a custom frame to house the mirror and the display. A deeper frame can accommodate the additional thickness of the Raspberry Pi and other components.
Next, install the Raspberry Pi. Load the MagicMirror² software onto your MicroSD card. This open-source software is a highly customizable interface for your smart mirror. Using MagicMirror², you can display a wide array of information, including local weather, news feeds, calendar events, and more.
Configure your Raspberry Pi to connect to the internet and launch MagicMirror² on startup. Afterwards, set your HDMI output to the correct resolution according to your screen and disable the screensaver to prevent the display from falling asleep.
Ensuingly, add voice recognition to your smart mirror. Setting up voice assistants on the Raspberry Pi is relatively straightforward. AlexaPi is a popular choice and is compatible with Amazon’s voice assistant. Google Assistant SDK also offers tools to incorporate Google Assistant into your Raspberry Pi system.
To calibrate your microphone, you need to find the card number and device number. Run arecord -l command in the terminal to list your recording devices and note down the card and device number of your microphone.
After the microphone is configured, test the voice assistant to ensure everything is working. An open-source command called “Snowboy” is recommended for voice detection to trigger the voice assistants.
Customize your smart mirror using the MagicMirror² configuration files. Here, you can add third-party modules or code your own. These modules can range from bus schedules to stock market info, task lists, social media feeds, and many more.
Keep your smart mirror software updated regularly. MagicMirror² constantly evolves, courtesy of a dedicated open-source community. New modules, enhancements, and bug fixes frequently roll out.
Creating a voice-activated smart mirror amalgamates craft, coding, and a smidge of patience. Whether you’re an experienced maker or a beginner looking to dip your toes into DIY tech world, a smart mirror project could be the perfect endeavor. With many online communities and resources available, the journey is as enjoyable as having the finished product adorning your home.
