Latest project, in progress, a voice controlled Magic Mirror. 5/4/2018 worked on this instead of going out for Gringo de Mayo. (#NotAMexicanHoliday).
As I got planning, research turned up someone who had already built something just like this: https://medium.com/@aallan/a-magic-mirror-powered-by-aiy-projects-and-the-raspberry-pi-e6a0fea3b4d6
But unlike that solution, I’d like to keep the button and probably recognize the hotword with some basic machine learning on the RPi itself.
Raspberry Pi 3B ($35) Microcenter
10x20 Shadow box from JoAnn Fabrics. ($21)
Old Screen recovered from 17″ Laptop (free) I preserved the back panel and cut it to fit with a jigsaw
Controller board and power for Screen ($36)
18″ HDMI cable ($5) Amazon
12″ x 24″ Acryllic Two Way Mirror ($37) Amazon
Google AIY Voice Kit ($10) Old version on Blowout Microcenter
Hot glue gun, double sided tape
Electrical tape (screen edges, random black out.)
32 GB MicroSDHC card (free) Microcenter
Custom base for Raspberry PI (didn’t want to glue board to the screen)
Custom base for the LCD controller
A replacement button if I want to turn off voice activation unless a button is pressed (the Google AIY Button is too big and too bright. I’d like something subtle.)
An acrylic backing if I want to create a clear back to show off the internals.

Google AIY included Examples
An OLED screen would be a massive improvement over this cheap laptop tft, mostly because the backlight is the part that breaks the “magic” if the screen is on.
The mirror coating is easily damaged, next time I might keep the original glass behind the mirror. It now has several scratches :-(
Get an aryllic scoring tool. I used a cutting knife but a tool would have led to less chipping.
Tried to save the nice back of the shadow box, and keep the lid opening, but in the end decided spacing was better without either.

New Google AIY Voice kit is $50 with a Pi Zero W, it’s significantly slower than getting the older kit and a Pi3 at $35. But is also significantly smaller. So it’s price vs. size really.
Really want to fit a battery pack inside so I can run it at least for a few minutes without power! (Imagine, removing the cable and scaring kids at a Halloween party!)
