Design Challenge Winners Honored at Fab Lab

“You won’t believe the energy and atmosphere you’ll experience at the Fab Lab. Watching young people design, fabricate, and create makes me feel optimistic about our future and humanity.”
~ Elena Ziu, NOVA Physics Professor


In early May, students who emerged victorious in NOVA’s 6th biannual Design Challenge were honored at an awards ceremony held at the Fab Lab. This year’s challenge tasked middle school, high school, and post-secondary students with designing products to improve the well-being of animals.

Entries were evaluated based on creativity, aesthetics, feasibility, and effectiveness. The competition welcomed middle school, high school, homeschool, and post-secondary students, allowing both individual participants and teams of up to three.

David De Costa, a student from Bishop Ireton High School, earned the grand champion title with his innovative “FoxWatch.” Recognizing the essential role that foxes play in the ecosystem and the dangers they face from fast-moving vehicles, David designed a device to help protect them. “I came up with this idea after noticing all the dead animals on the side of the road. I was inspired to create something to prevent that, and I hope my design will succeed,” David explained.

The “FoxWatch” features two concave parabolic mirrors: one shaped like a fox and the other resembling a traditional street warning sign. These mirrors reflect the headlights of oncoming cars to the sides of the road, especially at night when foxes are most active. The reflected light aims to momentarily dazzle the fox with brightness until the vehicle has passed. This system also enhances the visibility of foxes and other animals for drivers, thereby creating a safer environment for all.

As the grand champion, David received a Prusa MK4 3D printer, while the division champions were each awarded a Prusa Mini+ 3D printer.

Hauris Choudhry, representing NOVA, won the College Winner title with his creation, “HexaHive,” designed to promote honey bee habitats. Given the critical role honeybees play in the ecosystem and agriculture, and the challenges they face due to declining populations, Hauris crafted a compact and affordable 3D design of a bee colony. He modeled it after the traditional commercial bee box but included additional features. “I came up with the idea while driving through downtown Fairfax. I noticed all the apartments without backyards and thought a bee box could be a way to bring nature to the balconies,” Hauris explained.

Sean Fajardo from West Springfield High School won the High School Winner award for his “Bird Blocker” design, which aims to reduce the millions of bird deaths annually due to collisions or electrocutions. As urban development and deforestation displace birds, they are forced to nest in hazardous areas like power lines and wind turbines.

Sean’s design, made from wood and reflective metal, is cost-effective and easy to assemble. The “Bird Blocker” is placed between power line conductors to deter birds from landing, thanks to the reflective surface, encouraging them to relocate to safer areas. “I’m surprised that I won since my design is simple and can easily be made with wood, but maybe that’s what makes it a good design,” Sean said.

Middle School Winners Avery Woods and Marla Bud from The Potomac School devised “NailedIt!” after surveying classmates who own dogs about nail trimming, a task many dogs dislike, including Marla’s. They designed a clear, plastic box with a piece of sandpaper on top. Dogs scratch the top to reach a treat inside, which files their nails in the process.

Hudson Walker from the Academies of Loudoun High School received an honorable mention for his “Turtle Tunnel.” This design consists of two quarter-circle pieces that can be joined to form a safe tunnel for baby turtles traveling from land to sea, protecting them from predators and guiding their path. “I focused on the feasibility aspect of the design,” Hudson explained. “There are many coasts worldwide, so I aimed to create something affordable that can be mass-produced anywhere with a very simple design.”

Judges included Gillian Backsu, Ph.D., a NOVA biology professor; David Tuohey, a senior process engineer at BAE Systems in Manassas; and Dr. Bonnie Lefbom, a scientist, leader, and philanthropist.

Physics Professor Elena Ziu and her son Mihai, both avid participants in the NOVA Makers community, along with the Fab Lab staff, supported students throughout their design challenge journey. A big thank you to them, the judges, and our sponsor, BAE Systems!
