Last year I made a Smart Mirror

What's needed/what I used:

Atoms

• Sceptre 20" Ultra Thin LED Monitor

• 18 x 24in 2-way mirror

• Raspberry Pi 4 Model B

• Micro SD - 64gb is more than enough

• Google AIY Voice Kit (optional for voice commands)

• Wood, screws

• Wood Stain

Bits

• Raspbian

• MagicMirror²

• Etcher (or something similar)

Below is a video going over a similar build to mine

90% of the time is the physical assembly. From the stain to the cuts, to the screws, it takes quite a lot of time. The software setup is easy, especially if you are used to software dev tools(I say this looking back, at the time I had no experience with software dev, and it wasn't hard to get it going). MagicMirror's docs are very good for newbies to follow, as I was at time of creation.

It's a fun project, I use it everyday. The end product is quite visually striking and I get comments of confusion and excitement regarding it all the time by visitors to my apartment.
