A voice-activated smart mirror is not only a modern, stylish accessory for your home but also an impressive piece of technology. It lets you access information such as weather updates, task reminders, incoming messages, date, time, and much more, with a simple voice command. If you are a technology enthusiast on the lookout for a new DIY project, this guide will provide a step-by-step process on creating your voice-activated smart mirror.
Choosing the Hardware
The first phase of creating a voice-activated smart mirror involves selecting suitable hardware. The essential elements include a two-way mirror, a monitor, a Raspberry Pi, and a microphone.
Two-way mirrors, also known as one-way mirrors or smart mirrors, are made from acrylic or glass. They have a reflective coating on one side and are transparent on the other, which allows the digital interface to be visible when the monitor is on, yet giving the appearance of a regular mirror when it’s off.
Next, you’ll need a monitor. Almost any old or spare monitor lying around would do. Just ensure it doesn’t have large bezels, as they take up most of the mirror’s surface area.
A Raspberry Pi is a compact computer that can fit behind your mirror and run the smart mirror software. You can opt for a Raspberry Pi 3 or 4, depending on your budget. Raspberry Pi 4 offers better performance but consumes more power.
Lastly, a microphone is crucial for voice activation. While many USB microphones work well with the Raspberry Pi, The PlayStation Eye is a popular choice among DIY-ers due to its affordability and the fact that it functions perfectly with no additional drivers required.
Assembling the Hardware
Start by uprooting the monitor from its casing. This process will differ for each monitor, but usually, it involves unscrewing the back cover and carefully taking out the LCD. Remember, the screen is very delicate, so handle it with care to avoid damaging it.
Next, attach the Raspberry Pi to the back of the bare monitor. You can use a strong adhesive tape or hot glue. Connect the Pi to the monitor using an HDMI cable, and the microphone via a USB port.
The two-way mirror needs to be the same size as your monitor. If it’s larger, you’ll have to reduce it to fit. Stick the two-way mirror onto the monitor using an adhesive that won’t damage the screen. Make sure the reflective side faces out and the transparent side in.
Setting Up the Software
For the software, MagicMirror² is a great open-source platform specially designed for smart mirrors. It offers several customization options and is relatively easy to install on your Raspberry Pi. You’ll need to flash your Pi’s SD card with the latest Raspbian operating system. Afterward, install MagicMirror² by running the automated command available on their website
Once installed , you can configure your mirror as per your needs. You have the option to utilize several modules available in the MagicMirror² platform like a clock, calendar, news feed, and more.
To make the mirror voice-controlled, you’ll need to use voice recognition software. Some Raspberry Pi users prefer using Jasper, an open-source platform for developing voice-controlled applications. Once Jasper has been installed and set up, integrate it with MagicMirror² through a module.
You can add a wake word and program specific actions for different commands. For instance, you can set “Mirror, Mirror on the wall” as your wake word, and assign commands such as “What’s the weather like?” or “Do I have any new messages?”.
Final Touches
Your smart mirror is now operational. However, you might want to enclose it in a frame for a finished look. You can purchase a thick picture frame that fits your monitor or create a custom one yourself. Ensure the frame is adequately vented for heat to escape.
Lastly, hang your smart mirror on the wall, connect the cables, and it’s ready to go! Test the voice commands and ensure Jasper is responding promptly and the Magic Mirror² interface is displaying the respective screens.
This DIY project is perfect for aspiring coders who like hands-on projects. You not only create a futuristic gadget but also learn about open-source software, coding, and hardware assembly in the process. Designing and creating a voice-activated smart mirror offers practicality and fun, as well as a high-tech addition to your home.
Remember, it’s essential to keep updating the software regularly to ensure it works correctly and can utilize new features from software updates. Sustain its hardware by cleaning it and ensuring that it operates in a safe temperature range.
In conclusion, with the right tools and by following these steps, you can build your voice-activated smart mirror, making your daily routine more comfortable and technologically intriguing.
