COSMOS at UCSD's Cluster 2: Design and Control of Kinetic Sculptures assigned students a pendulum clock project, which covered many ideas and introduced students to new technologies. First, we worked with Computer Aided Design to craft a personalized look for our individual clocks, then simulated the motion on Working Model 2D. The physical parts were made with LaserCAMM, then put together with a multitude of new tools including drill presses, hand presses, taps, and more. In order to predict and analyze the oscillation frequencies of the clock, we were also taught new mathematical concepts such as differential equations. The goal of the project was to expose students to the manufacturing process and give them opportunities to problem-solve.

My pendulum worked well after facing many challenges. One important outcome that almost jeopardized the success of my project was forgetting to ream a certain hole, causing a crack in the acrylic. This threw the angle of the pendulum off balance, so I ultimately decided it was worth it to redo the upright. Otherwise, my clock ran smoothly and consistently. My prediction for the oscillation time was 0.5689 seconds, giving me a 13.43% error in comparison the final time of .67 seconds.
