But the documented DIY example is a framed display, not a conventional mirror: its screen shows calendar, weather, news, and messages rather than reflecting your image. The phrase “Magic Mirror” also has a separate technical use in E Ink Holdings’ display-development report, where it describes reflective technology, not a consumer dashboard product.
What “Magic Mirror” means in this context
E Ink’s familiar microcapsule technology uses positively charged white particles and negatively charged black particles suspended in clear fluid. An electric field moves particles toward the visible surface, changing how each area of the display looks. E Ink calls “Magic Mirror” a reflective technology in its flexible-display development; the company’s report does not describe a household mirror that overlays a dashboard. E Ink’s explanation of electronic ink and its 2014 annual report, published in 2015, refer to display technology.
A separate use of “E Ink magic mirror” comes from hobby projects that borrow the MagicMirror2 dashboard concept. The relevant example is better understood as an information frame: E Ink provides the display, while software presents useful information in black and white. It does not create the optical effect of a two-way mirror.
A documented E Ink dashboard build
In a 2019 report, Liliputing described Ben Roe’s project: a low-power E Ink information frame running MagicMirror2 software adapted for a black-and-white screen. It could display calendar appointments, weather forecasts, news, and incoming messages. The parts named in the report were:
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
- A Raspberry Pi Zero W
- A 7.5-inch Waveshare E Ink display
- A microSD card
- A micro-USB power adapter
- A frame, with 3D printing mentioned as one possible way to make it
The report’s cost figures are historical estimates only: under $100 for the project’s parts overall, about $50 for the 7.5-inch display, and $10 for the Raspberry Pi Zero W. They were reported in 2019 and do not establish current prices or availability. Liliputing’s 2019 project report is useful as a parts-list example, not as a current shopping quote.
What to check before building one
The old parts list does not guarantee that a newly purchased screen will work with a particular Raspberry Pi or software setup. Display kits can differ in controller, connector, and dimensions, so check the current display documentation against the board and software you plan to use before buying. Also plan the frame around the actual screen and controller dimensions.

Note: This device is not compatible with Linux.
- What You Get: Anker USB-C Hub (5-in-1, 4K HDMI), welcome guide, 18-month warranty, and our friendly customer service.
- Decide what you mean by mirror. If you want readable information in a frame, E Ink can suit that goal. If you want to see your reflection through a mirror surface while text appears over it, the documented project does not demonstrate that construction.
- Check viewing conditions. A MagicMirror forum commenter cautioned that a non-emissive E Ink panel may not be visible effectively behind mirror material. Treat this as a design concern, not a verified test result. The forum discussion does not establish how a particular panel and mirror layer will perform.
- Consider refresh behavior. The same commenter raised concern that screen refresh flashing could be distracting. The source is anecdotal and offers no controlled comparison; how noticeable it is in a build is not established there.
- Match the screen to the update pattern. A display that mostly presents changing-at-a-glance information is a different design choice from one expected to update constantly. The cited sources do not provide measured refresh performance or a side-by-side test against conventional smart mirrors.
- Account for light and usable area. Check whether the panel’s viewing area, lighting needs, and front-light provision suit its intended location. The project report does not specify a front light or establish how its screen performs in every room.
How it differs from a conventional smart mirror
| Question | E Ink information frame | Conventional mirror-style dashboard |
|---|---|---|
| What you see | Information on an E Ink panel; the documented example is described as a smart picture frame, not really a mirror. (Liliputing, 2019) | A reflection with information intended to appear on or behind the mirror surface; the cited sources do not specify a particular product or construction. |
| Documented hardware | Raspberry Pi Zero W, 7.5-inch Waveshare E Ink display, microSD card, USB power, and a frame. (Liliputing, 2019) | Not stated in the cited project report. |
| Refresh concern | A forum commenter raises flashing as a possible distraction; no controlled result is reported. (MagicMirror Forum) | Not compared in a controlled test by the cited sources. |
| Cost evidence | Historical 2019 estimates only; current pricing is not stated. (Liliputing, 2019) | Not stated in the cited sources. |
What patents and company terminology do—and don’t—show
E Ink Holdings’ report uses “Magic Mirror” for reflective technology in flexible-display development and discusses plastic-backed displays and touch modules designed without reducing display reflectance. That is a description of display development, not evidence of a ready-to-buy household mirror dashboard.
A patent record titled “Graphic mirror” describes a display architecture with reflective and transmissive modes. A patent describes an invention; it does not establish that a matching commercial product is currently available. JP6588659B2, “Graphic mirror”.
