Project Proposal Guideline

Introduction

Statement of Purpose

We wanted to make a project that had the potential to be useful to us in our daily lives. With this in mind, we settled on building a smart mirror. A smart mirror is a two-way mirror with monitor behind it, thus allowing information to be displayed on the other side of the mirror. In our case, the mirror will display some vitals like temperature, time, and the weather. It is a smart mirror because it will interface with an Amazon Alexa so that it can be “asked questions” and then display a response. We will also connect LEDs to a raspberry pi, and modulate their intensity based on the sound playing from the alexa.

    1. Background Research

      We are basing our project off of a youtube video made by one of our favorite tech youtubers. As we stated earlier we are driven by the desire to create something that is useful to us in our daily life. We believe that the Smart Mirror has the potential to change our lives for the better. Our project is different from the one that we find online because are integrating a speaker into the design of the mirror.


Design Details

    2. System Overview

      The part labeled “sonoff” at the bottom of the diagram is wifi-enabled, and thus can interface with the Amazon Alexa to control the power to the mirror. There are two power supplies-- one for the Rasberry Pi (5V) and one for monitor (12V). The Raspberry Pi controls both an LED circuit and the monitor. The LED circuits will be used to coordinate the sound from the Alexa and LED strips. 

Parts

2 wood planks (28 by 2.5)

2 wood planks (22 by 2.5)

Glue for glueing wood together 

Sandpaper

8 support nails

Inside frames (idk length)

Mirror (idk dimensions)

Raspberry pi

Monitor

Raspberry Pi heat sinks

Felt (to block light)

Support screws

LED lights

Wiring

Sony wifi on/off switch

Speaker

Possible Challenges

The biggest challenge will likely face is our inexperience. However, there are also some specific challenges will likely face. One issue that could arise are wiring problems. We need to slide our wires through the frame, which is a tight fit. It is very likely that the wiring will not be perfectly connected the first few tries. Our circuit could also have issues in the connections.

Comments:

We've had a few mirror groups in the past. I would encourage you to look back at their projects to inspiration, or any problems they came across.

Also, focus on implementing the most basic working version of the mirror before worrying about additional features. Have a mirror that wakes and displays basic info (weather, emails, etc) would already be impressive, even if it didn't have a lot of different features.

Yep, use past semesters' wiki pages as support. Great diagram!
