12/4/2023 0 Comments Magic mirror project![]() Eyes are not good judges of brightness, but careful measurement of your mirror with a light meter will confirm that it cannot simultaneously transmit 80% of the light from the monitor while also reflecting 80% of the room light. In truth, if the material is reflecting 90% of the light, then it is transmitting only 10% of the light from the monitor behind the mirror. Minus a small amount of absorption by the material, the percentage reflected + the percentage transmitted light cannot add up to more than 100%. The optical illusion of "one way" mirrors depends entirely on the room being more brightly lit than the space behind it. This is a simple y shaped cable harness where the LCD and Laptop input power is parallel.Ī "one-way" mirror is simply partially silvered material, which reflects/transmits equally in both directions. Lastly you wan't to solder a cable that plugs into the wall on one side and plugs into both the display and laptop power supply. Again make sure all the stippied components still work. Remove any bezel and stand till you're left with the bare lcd pannel and the small driver and power boards that are linked to it. Once the laptop motherboard is ready, Decase the monitor too. If the mother board can't boot, try to retrace your steps and figure out what part is preventng the motherboard from booting. connect your motherboard to your external display and make sure that the bare motherboard can boot before you proceed. You can disconnect the laptop display cable, battery, track pad, and keyboard cables at this point. Take the motherboard of the laptop out and make sure that the WiFi card, ram, cooling fan, and hard disk are connected to the mother board. Once inside, make sure to document any step you take either with a photo or with a written note. If need be, look for an online repair guide to see how the laptop is dissembled. Start by removing all the screws you can find on your laptop. You can also skip to the Software step to test the software and see if the OS runs well on your machine.īefore you start, make sure to discharge your body ESD or use ESD safe tools. You also want to make sure all the hardware works before before you disassemble and install it in the mirror. However removing the electronics of the laptop and monitor allow you to get a significantly thinner and easier to build mirror. Do note, this step isn't cumpolsory and you can direectly atach your electronics behind the LCD. Rain meter widgets as linked in the software pageįor more projects visit my website at īefore you start disassembly, note that the following steps will most likely void your laptop and monitor's warranty. A Cheap Display appropriate for your glass size. Wood, screws, nuts and bolts for attaching hardware to the frame.ģ. Glass with 1 way mirror film applied by hand (you can also purchase a readymade one way mirror)Ģ. If you don't have any old laptops, you can very easily get a second hand laptop of websites like ebay for dirt cheap.ġ. The best way to do this was to use an old unused that was lying at home unused. So after building this very smart mirror with my raspberry Pi as the brain, I decided to upgrade it to something more powerful, yet I wanted a cheap alternative especially considering how cheap the Raspberry pi is. To do this I drilled 4 holes into the mirror and attached the frame to these screws in the glass. One more way my build differs is that I didn't want a frame around my mirror and wanted to maintain a floating glass look rather than building a frame around my smart mirror. browse the web and maybe watch some YouTube/Netflix. Furthermore the raspberry pi hardware struggles to do anything more than display static widgets.I wanted to be able to walk up to my smart mirror and be able to give it commands via voice. There's nothing wrong with the Magic Mirror but it hasn't been built to be interactive and mostly displays static information. Unlike most of the smart mirror builds that are based of the Magic Mirror OS built for the Raspberry Pi, this smart mirror is built on a windows platform. ![]() The mirror also has an Amazon Echo Dot hidden behind it to enable all of Alexa's vast voice control features just by calling out to Alexa. One way mirrors can reflect most of light that hits the surface while still allowing some of the monitor's video behind it passes to the surface of the mirror. Straight out of the future, the smart mirror is simply a display behind a one way mirror.
