14 PCB007 MAGAZINE I APRIL 2019 simplicity than is currently used when oil spills, won the Compos- ite Materials Design Award spon- sored by Dixie Chemicals. Com- bining an oleophilic/hydrophobic composite filter with flow meters and pressure sensors, the device filters out water to only absorb oil while reporting success back to a laptop or computer. The students who built the prototype were largely unfamiliar with the Ardu- ino language, soldering, and use of rapid prototyping, all of which proved central to their project. Overall, they managed not to just understand but master each and use them as needed for their pro- totypes. Team members included Katherine Nelms, Wyatt Phillips, Sabrina Meli, and Haley Higginbotham. Beam Print Beam Print by Team 46 was another stand- out prototype we observed that was built to simplify the laser cutting process and stream- line rapid prototyping. None of the members of team members had experience in AR or app de- velopment, which were central to the success of their device. Team members Dieter Brehm, Sam Daitzman, Dhara Patel, and Jonathan Kel- pressed by the relevancy of their design based off of a need they had experienced in their lives, and their willingness to learn new skills alongside the engineering flexibility they had to solve a real-world problem. When reflecting on their MakeHarvard expe- rience, Roquitte and Stigman commented, "We were able to build a very complete and polished project." Further, they said, "We learned some new soldering skills and Android studio/app de - velopment. We believe that this project could make traveling on electric skateboards much safer. We also believe that this will promote the use of electric skateboards, which are a clean and practical mode of transportation. We will be looking into developing that project further and potentially turning it into a product." Other Impressive Prototypes Outside of our competition category, three other prototypes that impressed us included: • Hydrophobe unmanned surface vehicle (USV) • Beam Print • CocoGogo Hydrophobe USV Hydrophobe USV, a device meant to fil- ter and clean oil with greater efficiency and Figure 5: Some competitors arrived with their own equipment. This student- made 3D printer is one example of the home-brew gear on hand. Figure 6: Beam Print team accepting the BMW Applied AR/VR Award.
