Product overview A sundial model and DIY kit that measures time using the position and shadow of the sun. Designed as a small, portable sundial clock and scientific sundial, it recreates the traditional timekeeping method used historically in ancient China. The kit requires no electronic device to tell time. Key benefits Reliable offgrid time reference: Lets you estimate local solar time when electronic devices are unavailable. Educational and handson: Teaches principles of astronomy, geometry, and historical timekeeping through assembly and use. Portable and simple: Small sundial clock format makes it easy to carry, place in a garden, or use in a classroom. Engaging demonstration tool: Combines scientific accuracy with historical context to illustrate how cultures measured time before modern clocks. How it works The sundial uses a gnomon and a marked dial to cast a shadow. The shadow position on the dial corresponds to the approximate hour of the day. Placement and orientation toward true north and local latitude adjustments improve accuracy. What makes this kit stand out DIY model format encourages active learning and skill development. Based on classical sundial principles and historical examples of use in ancient China. Functions without batteries or electronics, relying only on sunlight and basic alignment. Features and compatibility Function: Measures time by the sun shadow and indicates hour positions on a dial. Format: DIY model kit suitable for assembly and demonstration. Size: Described as a small sundial clock suitable for tabletop, portable use, or outdoor placement. Exact dimensions depend on the kit model. Materials: Kit components supplied per model; material composition varies by kit and is indicated in product details. Performance: Accuracy depends on correct alignment, local latitude setting, and clear sunlight. used outdoors under direct sun. Practical use scenarios Classroom activity: Assemble the kit with students to demonstrate solar timekeeping, latitude effects, and historical methods used in ancient China. Outdoor display: Install as a small garden or patio clock to mark daytime hours without electronics. Field or camping demonstration: Use as a basic orientation and time reference when electronic devices are unavailable, combined with correct alignment procedures. What to expect A handson sundial model kit that illustrates scientific and historical timekeeping. The device measures time by solar shadow, requires correct placement for accuracy, and is suitable for educational, decorative, and practical outdoor uses.
