Hardware and Software Locker Team


I was born in China on October 22, 1997 and moved to San Francisco when I was around 2 years old. Because I moved so early in my life, I don’t know too much about my Chinese culture. As I grew up, I got into video games especially the difficult ones because it taught me how I can overcome obstacles if I apply myself. Another hobby that I got into was building miniatures because I like the feeling of putting something together by myself. Both of these hobbies pushed me go into computer engineering because while it is difficult, I can become better and eventually succeed and it allows me to build things in lab that I can show people.


Initially, I picked EPICS because I needed a tech elective and I didn’t have the requirements for the other electives. As the weeks went by, I learned a few things like how to work in a team and why the whole team needs to be informed. These lessons can help me later in life when I work with other engineers on projects. This class has also taught about things that I wouldn’t learn in my other class like how to write a resume and what to do in an interview.


After graduating, I hope to find a full-time engineering job but it might be difficult since I haven’t found an internship yet. I’ll also probably pursue my Master’s Degree so that I have better opportunities in the future.

Happy Holidays and Smart Locker UI

Thanksgiving has come and gone and Christmas it just around the corner. With the year coming to an end, the Smart Locker team would like to remind everyone to stay warm, hydrated, a wish everyone a happy 2019.

Below is a draft of the Front-end UI flow chart on what we expect the screen will show for the advance locker system.  Our team software engineer will be using Adobe XD to create the UI. The backend will be running on a Raspberry PI with a touch screen as interface.

A mock up of what main screen can be seen below.  The UI will be touch screen so anyone that has experience touch screen smartphone will have a easy time navigating the menus.  

Our software and computer engineer are still working out the bugs of the system.  More to come.

Project Software Designer
I was brought up in Punjab, India for my first decade of lifetime. As growing up I always had a passion for technology and art. With these two passions I was able to create some very unique projects throughout my lifetime. My first project was a waterboat made with paper which was powered by a small electric fan. I also have a great passion for photography and video making. Combining both of these skills allowed to learn much more about computers and how technology works.
I joined EPICS mainly because it was a requirement for my technical elective. But after choosing this project I could see how important this project could be for the homeless people. I always believed that everyone has the ability to help the needy. From this project I get inspiration to help people with a secure place to keep their belongings.
In the future, I would like to continue building for the better of this society. I would like to find a job in the front end development of softwares and create easy and meaningful softwares.
