Berried Treasure

Captive Portal/Entry Page
Previously Left Comments
Comments on Pi's Screen

Inspiration

We wanted to work with IoT devices, and thought about where the Raspberry Pi could be a fun tool to rework something fun in the physical world. After some thought, we decided to make a geocaching-like system with the Raspberry Pi.

What it does

Berried Treasure allows people to connect to the Pi's hotspot and access a captive portal. This captive portal will allow user's to enter their name and a comment, which will display on a results page that lists all of the most recent comments. This allows people to see who else has previously connected to it, giving a living history similar to real life geocaches.

How we built it

We built Berried Treasure as a Django webserver hosted on the Raspberry Pi. The Pi had multiple changes made to settings in order to capture and redirect web-traffic to the captive portal. The Django server then handles user's accesses to redirect them to the correct page. We chose Django because none of us were familiar with the framework.

Challenges we ran into

Configuring Pi, using and learning Django for the first time, & capturing and redirecting DNS traffic to create captive portal.

Accomplishments that we're proud of

We finished all major goals to create a working demo.

What we learned

How to develop in an MVT Framework, configuration of basic IoT networking, setting up and using Raspberry Pi, how to create a web application using Django, implementing a Bootstrap CSS file.

What's next for Berried Treasure

Rebuild webserver to host it off of the Raspberry Pi, allowing multiple Pis to be hosted and registered to the server. This would allow the results of each Pi to be viewed from the cloud, while additional comments could only be added through local hotspot access. We would also like to add a login system allowing users to track previously accessed caches.

Created by

I developed the initial design and idea for Berried Treasure. I then took a heavy role in working to create a captive portal which would redirect all web-traffic through the Raspberry Pi's hotspot, and automatically open the webpage upon connecting to the wifi. I also helped to work through issues with general development on other aspects of the project.

I worked on configuring the initial setup of the Raspberry Pi and its associated WiFi netowork, along with designing the websites logo.

I helped my teammates learn to use Django and how to develop in an MVT framework. I worked to setup the adafruit touchscreen and as well as a captive portal hotspot used to submit your name and comments upon finding the device.

I worked on setting up the Django template for the project, as well as creating the SQL database used to store comments. I also worked on setting up the CSS, and optimizing the basic layout of all the HTML elements using HCI design principles.

I worked on setting up and understanding Django. I also applied bootstrap to both index.html and results.html and made everything look prettier.
