Smart Mirror or Smart Mirror is a device in the form of a simple display, on top of which is a one-way mirror. The latter possesses the ability to reflect almost the entire light falling on its surface, but at the same time skips images from the screen, which is behind it, and allows it to see the user.
Once I bought for myself Raspberry PI - the purpose of the purchase was in the building on the gadget of something like in those cases when at work I borrow and the soul will ask something new and interesting. This is how the retrocons assembly history and the RGB color management module appeared. However, the desire to do something else remains, something more practical and frequently used. So Pierla The idea of assembling a smart mirror on Raspberry Pi.
Pulling the Internet, found a bunch of examples, studied them. Fortunately, you can choose, there are options for every taste and on any budget. There was a desire for quick, simple, inexpensive assembly of a similar device, while the quality was not lost. Further - Description that it was necessary for this, and the result of work.
The smart mirror device contains three parts: a computer, monitor and mirror itself.
The biggest problem became, in fact, the search for a two-way mirror. On one surface, it should skip the rays of light, and on the other - not to skip, and reflect the one that the feature is concluded - so we can consider what is happening on the monitor display, and however, a mirror reflection is provided.
It was decided to abandon the order of the real mirror, as it would be an extremely profitable option - the price of it is similar to the price of a cast-iron bridge. The alternative is found - as a conventional sunscreen film for facades, the light-resistance of which is 8-10%. You can easily thwart.
Checking light source was carried out like this: on the reverse side, the phone was pressed and at that moment when he stopped to be visible for reflective coating, then it is not necessary to watch, and you should take the previous one. Nuance - There is a self-adhesive for ordinary glass. If something deteriorates, you can take another fragment of the film that is sold in rolls. Just tear off the unsuitable and cut off the new necessary part. The result is quite worthy.
For the frame, the most primitive design was chosen, since I did not have experience with the wood.
Source materials with the specified value:
one . Raspberry PI 3B with built-in WiFi module - 3000 rubles.
2. . 19-inch LG monitor, VGA cable - 1500 rubles, taken on Avito.
3. . Working instruments and materials in the form: Tree bars, saws, glue, sandpaper, simulators, roller from the fabric, rubber "spatula" to smooth out the film - 800 rubles.
four . Simple glass of the desired size - 300 rubles from Avito.
five . Sunscreen film 1.5x1 m - 500 rubles.
6. . VGA-HDMI adapter (VGA input - on the monitor, and on the device - HDMI) - 300 rubles from Avito.
As a result, it turned out independently done, a full-fledged gadget, worthy of constant interest and delight from the guests, and the master is worthy praise.
