Executive Summary
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.



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.

Packaging
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.

Highlights
Here is where you brag about what your project can do.

Include a YouTube demo the audio description.

Theory of Operation
Give a high level overview of the structure of your software. Are you using GStreamer? Show a diagram of the pipeline. Are you running multiple tasks? Show what they do and how they interact.

Work Breakdown
List the major tasks in your project and who did what.

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.

Future Work
One thing would be to get the twitter plugin in on falcon. This would allow tweets to be displayed on the matrix instead of the the weather.

Another thing that we could get working but would be neat is adding some sort of texting feature that would display texts on the cap instead of weather. It could say the name of the person and a message before it.

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!".

Conclusions
Give some concluding thoughts about the project. Suggest some future additions that could make it even more interesting.
