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. |
