When I started on this project, I intended to have a tablet PC behind a 2 way mirror. After mocking it up, I realized that it would be too small.
I just happened to have a 22" IPS display handy and the size was right, so I took the screen out of the plastic housing and measured that for a mirror and a frame.
I ordered the mirror from a place called TAP plastics.
I then cut pieces for a frame that would hold all the electronics and the mirror.
I used 1"x3" pine for the box that holds the screen and whatnot, and 1/2"x3" pine for the facings.Cutting by hand is tough work.
Frame construction finished. 22.5" tall, 16" wide.
I used glue and countersunk brads to hold the facings to the box.
The corners weren't perfect.
So I filled them with sanding putty.
The Raspberry Pi 2 that runs the software for the magic mirror. It's mounted on a 3d printed holder. The blue, yellow and green wires at the top go to a thermal motion sensor, and tells the screen when to go in and out of low-power mode. Also, if you look really close, you might see 2 air holes drilled into the box above the pi. There are more on the bottom of the box, for air circulation.
Magic Mirror 2. There many add-on modules. Loads more have been added since I built this mirror, and add functions that will be interesting to play with.
