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.

<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.

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: <Insert the back of the board here>

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.

Date Milestone
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.

Future Work

Suggest addition things that could be done with this project.

Conclusions

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