A method of making a peeping impossible "magic monitor", materials are 3D glasses of a movie theater and a display with a polarizing plate peeled off



Two polarizing plates (polarizing filters) are used for the liquid crystal display, but one of them is peeled off, and instead by using the polarizing plate used in the cinema's 3D glasses, anyone else It seems that you can also create "magical monitor" that you can not see peeking, actually snow Yuki @ technical document 3@ Yk_ichinomiya) Has released a demonstration video on Twitter.


Through the lens you can see"Magia Record Magical Girl Madoka ☆ Magika Gaiden" Official Site.


However, if you do not let through the lens the screen is white.


Also, changing the angle of the lens changes the color ......


Returning to the appropriate angle will make it visible again.


Although the idea itself of "magic monitor" already existed, it seems to decide to actually make it because it seems interesting.


Originally, since the liquid crystal display is made by sandwiching between two polarizing filters, one of them is removed, and a lens of 3D glasses is substituted for the lens.


The book that summarizes how to make it will be held at Akiba Square on Sunday, October 22, 2017Technical writing 3It is scheduled to be published in.
