With a team of three (The Magnificent 7's), our final capstone project was a tech demo of resin embedded electronics which would could be brought out to interested seniors in high school of freshman engineers and demonstrate what electrical engineering is capable of.
The resin embedment was a design requirement by our sponsor to make the system more durable and, frankly, simply look cool. The vision was that any aspiring engineers would interact with the resin cube with an IR transmitting wand, more detail in the site linked below, while also being able to see what electronics were used to make that interaction possible.
