Team Snack Overflow

Landing Page: Displays Progress
Start Trip Page: Prompts the User to start their drive
End Trip Page: Prompting User to enter their ending Odometer to finalise trip
Trip History Page: Displays full range of information in regards to the trip as per the NSW Leaners Logbook

Inspiration

As NSW learner drivers, we kept losing logged hours simply because we forgot to write trips down. The official logbook requires precise details including suburbs, road types, weather conditions, odometer readings, and recalling all of that after a long drive is unrealistic. We wanted to fix that.

What it does

Our product will automatically track your location whenever you start a trip, using the data to gather information about weather, traffic, and even the type of roads you drove on. We aim to prevent the user from having any need of remembering the details about a drive. Just hop behind the wheel, press the "start" button, and don't crash! We return values in a table mirroring the official logbook table and following logbook acronyms, e.g. Sealed Road = S.

How we built it

Flask backend with SQLite, vanilla JS frontend, deployed as a PWA for mobile access without an app store. We integrated Open-Meteo for weather and sunrise/sunset data, OpenStreetMap's Overpass API for road classification, and OpenRouteService for traffic analysis

Challenges we ran into

Our team encountered an innumerable number of challenges during development, such as some team members having upcoming exams and hence having to juggle their time. We also did not have much experience with hackathons (this is our first one), so we lacked the knowledge needed to properly schedule our development.

Accomplishments that we're proud of

We are very happy with how well the map was integrated into the webapp. Additionally, all of our members were on task for the majority of the duration of unihack!

What we learned

We learned the importance of coming in to a hackathon with a solid plan and setting out a development schedule before commencing the chaos.

What's next for Team Snack Overflow

We plan to get lots of sleep and do well in university exams. 90+ WAM!!!

Created by

My role spanned both backend and frontend, which made for a busy three days.

On the backend, I built the trip analysis functions, starting with trip_weather, which queries the Open-Meteo API to determine weather conditions at the time and location of the trip, and trip_time, which calculates the day/night hour split using real sunrise and sunset data for the driver's GPS location.

On the frontend, I built and styled the main pages using Bootstrap and the NSW Government colour scheme, making sure the UI matched the aesthetic given this is an adjacent tool (NOT OFFICIAL).

I also spent a fair amount of time debugging Jinja2 template logic.

This was my first hackathon and the experience of shipping something end-to-end in three days was genuinely valuable. I came in knowing Flask and Python, and left with a much better understanding of how a full stack fits together in practice.

Within this project, I worked mainly on its back-end, creating the logic behind the functions that analyze the trips, such as trip_suburbs, trip_traffic, trip_weather.

At first, understanding the whole project was daunting, however, once I understood how the database worked, everything fell into place.

Within this project, I was also forced to go outside my usual expertise and dabble with front-end code for the project's debugging. I had an interesting time reading and deciphering JavaScript, though I'm still unsure that I can understand it all!

Overall, even though there are some aspects that I may have been able to contribute more, As a first time Hackathoner, I am regardless satisfied of the project that my team and I have managed created today!

I worked on a lot of different parts of the project. I helped set up the initial DB schemas, wrote the vast majority of the front-end geolocation and mapping code, wrote part of the back-end trip analysis code and was the IRL tester running around with a phone seeing if the website worked.

I worked on the front-end of the website. Using Bootstrap to tailor design our UI/UX to best fit the guidelines outlined by the NSW Government.

The Hackathon was an amazing experience for me, acting as a catalyst to evolve my overall web development skills and team work. Especially in upskilling my JavaScript knowledge and my ability to understand backend and frontend integration.
