We’re not quite old enough to remember a time when the thought of automatic doors was science fiction, but we do remember wondering if we’d ever see magic mirror technology become a reality within our lifetime. Maker Becky Stern makes it look easy with this Raspberry Pi-powered smart mirror.
- Raspberry Pi 4 Model B (Raspberry Pi 3 will also work for this build)
- An old computer monitor or other HDMI display
- Power strip
- Two-way mirror glass
- Sturdy frame
- 3/4″ plywood
- LED strip with its own power supply (optional)
Becky used open source MagicMirror2 software, which has hundreds of IoT applications to choose from. You can display everything from the local weather and public transport options to your own personal calendar. There is a really nice easy-to-follow walkthrough on magicmirror.builders.
Magic Mirror was also a winner in The MagPi’s special 50th issue celebrating the greatest Raspberry Pi projects.
How is it made?
An old Dell monitor is used to display all the smart data. Becky followed tips in this video to strip the bezel, leaving a thinner piece of kit to work with. She also rerouted the buttons under the original bezel so they could still be used once the monitor was inside its new magic casing.
Plywood strips fill the gaps between the monitor and the frame, and a 12V LED strip is tucked in around the edges to illuminate the magic mirror from behind.
With the two-way mirror glass and everything else packed into the frame, the whole build weighs 40lbs, so you’ll need a really sturdy TV mount to secure it safely to the wall.
Thanks for making everything look so easy, Becky. And for the great photos borrowed from your website.
