State Fair Design
Date
October 2025

For this project, our team was tasked with designing and building a fully mechanical State Fair exhibit within a 6-foot by 3-foot footprint. We developed a two-player, basketball-themed pinball machine constructed entirely from mechanical components. The design incorporated levers, springs, ramps, and flippers to control ball movement without the use of electronics.
The machine featured multiple interactive elements to create a competitive and fast paced experience for players. Throughout the project, we focused mainly on fabrication, durability, and consistent gameplay performance. Detailed design specifications and component descriptions are provided in the information sheet below.
