The initial sketch for the string launcher is shown above, we figured out how to build the mechanics through a DIY video discovered on Youtube. The build required techniques such as soldering, drilling, and laser cutting, and a proper understanding of circuits as we needed to connect two motors to just one battery pack, the motors also spun in different directions depending on which side was positive and negative. I already knew soldering from a circuits class in seventh grade, and laser cutting I could learn by asking one of the design teachers that worked with us during the project.
