Using an Arduino, we hope to create a projection device that attaches to glasses and can display data from an external device thru bluetooth

The hardware for this project was, for the most part, successful. We were able to achieve our major goals of creating a lightweight and durable case that houses a compartmentalized electronics system, along with a system of mirrors and a lens to display an OLED image onto the retina. The whole case is also easily portable, lightweight, and wearable, as we were able to attach it to a pair of large safety goggles. Below are several pictures of the goggles on a person.

The software aspect of our project was far less successful. We had serious difficulties in connecting the Bluetooth module to the computer and running a connection between the Data Glasses and the SoftwareSerial on the computer. There was some unidentified issue in the connection and pairing process, as the computer was unable to connect to the HMSoft Bluetooth output of the module. Thus, the Bluetooth aspect of the Data Glasses was a failure. However, the OLED worked perfectly and we were easily able to code it to display text and images. The final product incorporates a stopwatch timer displayed on the OLED screen that can be started and stopped through the press of a pushbutton on the exterior of the glasses.
For the past few months, we've been prototyping. We spent a lot of time tinkering with the distances between the optical elements of the HUD and reprinting the case for the device based on our changes. Additionally, we've begun soldering together the final electronic components for the device and will shortly have a finished product.
Here are some pictures of our progress:
