# Problem

Let's face it: recording your daily activity is hard. When I grew up as a kid, I hate those homework, you know, that asks you to describe what you have done during a day. I think it is such a repetitive, exhausting, and boring work. It takes so much of my precious time to be better wasted somewhere else.

# Solution

SnapLog is a camera that you can wear on your neck that is lightweight, versatile, and good looking. The device is designed to create a timelapse of your daily activities. To do so, the camera will take a photo in a interval of a few minutes, and sends it over to your phone wirelessly. The phone app will compile them into a video and encode it at the end of the day.

# Solution Components

## Subsystem 1

Communication: This part of the system communicates with the phone software that transfers the image captured by the camera.

## Subsystem 2

Imaging: This part of the system communicates with the camera module and captures images. It also applies algorithms to enhance the photo if necessory.

## Subsystem 3

Sensing: This part of the system determines when it is the best opportunity to take the photo or adjust the photo based on lighting and environment conditions. It also include component such as RTC to remember time and send wake signals.

## Subsystem 4

Power: This part of the system controls the power sent to the rest of the system. It handles battery charging and protection, sleep, and power sequencing to different modules.

## Subsystem 5

Phone software: this part of the system runs on a smartphone of the user that handles the video production or photo storage. It communicates with the camera to receive the photo.

# Criterion For Success

- The device is capable of automatically capturing image every few minutes.
- The device is capable of power management.
- The device is capable of wirelessly transfering files to a smartphone.
- The mobile software is able to create a video using data from the camera device.
- The device is under 50g.
- The device's main controller is capable of sleeping and has a net power consumption lower than when running normally during a period of time.
- The device uses a microcontroller.
- We designed the PCB and produced it.

Logic Circuit Teaching Board

The proposal our group has is of creating a board that will be able to teach students about logic circuits hands on. The project will consist of a board and different pieces that represent gates. The board will be used to plug in the pieces and provide power to the internal circuitry of the pieces. The pieces will have a gate and LEDs inside, which will be used to represent the logic at the different terminals.

By plugging in and combining gates, students will be able to see the actual effect on logic from the different combinations that they make. To add to it, we will add a truth table that can be used to represent inputs and outputs required, for example, for a class project or challenge. The board will be able to read the truth table and determine whether the logic the student has created is correct.

This board can act as a great learning source for students to understand the working of logic circuits. It can be helpful in teaching logic design to students in high schools who are interested in pursuing a degree in Electrical Engineering.

Please comment on whether the project is good enough to be approved, and if there are any suggestions.
