The project that we are doing involves an LED Matrix and the Beagle Bone. We are putting this matrix inside of a graduation cap. An example can be seen here: https://imgur.com/gallery/xr0P0.
<Insert Final Product HERE>
The above image will be inside cap and will display twitter tweets that are tweeted within the SRC during graduation. The cap also will display GIFs and animations.
The final packaged product is the LED matrix with everything wired neatly behind the matrix. There is cardboard to make sure that everything stays in place and supports the cap.
The final product looks like this:
This cap is powered off a power bank that supports more than 2.4 Amps.
The project is located on GitHub here: https://github.com/LinuxDevon/32-bit-Embedded-Linux/tree/master/LED%20Graduation%20Cap
The GitHub has a README on how to install the necessary software for this project.
Here are the links for the specific hardware we used for this project.

Pocket Scroller Wiring
This table maps the Pocket Scroller for the Pocket Beagle to the pins on the the Pocket Beagle to eliminate the need for the scroller and reduce space.
Below is the reference to the Pocket Beagle to map to the pins given above.

Theory of Operation
List the major tasks in your project and who did what.
|10/28/2018||Have Falcon working without PocketScroller Cape|
|11/2/2018||Have twitter API reading tweets on PocketBeagle|
|11/4/2018||Have twitter displaying tweets on LED Matrix|
|11/6/2018||Figure out how to display tweets as well as sequences on LED Matrix. IE Falcon and our handwritten stuff running at the same time.|
|11/9/2018||Have everything fitted to cardboard so that we can wear it as well matrix and beagle running off of power bank|
|11/12/2018||Wrap up final documentation|
Also list here what doesn't work yet and when you think it will be finished and who is finishing it.
We tried to get the twitter API to work with Falcon. However, because of a lack of documentation and an unfamiliarity with PHP, we could not get this done. Instead, we tried to get texting to the LED display to work. However, for the same reasons as the twitter API, we also couldn't get this to work! Therefore, we ended up using a weather API that prints out the current conditions of Indianapolis.
Twitter API: Figure out how the twitter plugin works with falcon and get it working. You can then display tweets on the LED matrix.
Twillio: Figure out how to get Twillio configured with falcon. If this ends up working, you can then text a default number and display "Congratulations RANDOM_NAME!".
Give some concluding thoughts about the project. Suggest some future additions that could make it even more interesting.
