How does technology evolve and how is the succession of it in a student-run amateur group where members change annually, a stark contrast to professional R&D? The University of Tokyo Astronomy Club has been producing and presenting handmade planetariums every year for 45 years. This presentation reports on the unique and discontinuous path of development that our planetarium technology has followed under these specific circumstances.
This poster details the technological evolution of our projectors and domes from our beginnings in 1980 to the present day. For instance, our dome has evolved from an initial wooden frame structure (6 meters in diameter) to an air dome in 1993, and now to a 12-meter dome with a seating capacity of over 100 people. In addition to the evolution of our star projector, we introduce the development history of unique devices such as our Firefly projector and the Carl Sagan Projector. This history also includes "lost technologies" that disappeared due to difficulties in technical succession, showcasing our journey of trial and error.
This record of our unique development, achieved with limited student resources, serves as a compelling case study that offers a new perspective on innovation born from constraints and on the universal challenges of succession of technology.
