Alexa-Enabled Touchscreen "Tablet"

Overview

A few years ago, I made the Mystic Mirror - a magic mirror with Alexa built in. I also made a display last year for my Compost Professor project.

Full disclosure - this isn't a detailed write-up about creating the project. What I've built so far is still very much "work in progress." I just wanted to share what I've done so far, some cool images, and provide attribution to Adafruit for their great tutorials.

Background

I remixed/combined three projects to build this project:

• Adafruit - 7 in Raspberry Pi tablet

• Adafruit - 10 in Raspberry Pi desktop

• Alexa - AVS on Raspberry Pi project

Key Functionality

• Screen turns off based on motion detector

• LED light indicates status

• Displays current time and temperature (similar to an Echo Show/Spot)

• Alexa responds to voice prompts and displays images for display cards

• Physical button for integration to the Compost Professor project

Next Steps

• The GUI is currently written with Node.js and socket.io - I need to update to GUI to better integrate with the AVS code.

• I want to add physical buttons for volume and mute.

• I need to figure out the voltage and amps needed; I kept getting brownouts and making this battery powered was a no-go.
