Wind Turbine Motor Blade DIY Set for handson wind power demonstrations and small DIY projects. Simple to assemble, durable, and made for clear demonstrations of converting wind energy into usable electrical power. Key features Complete set includes generator, propeller, USB cable, and 5watt USB bulb for immediate demonstration. Propeller length: 18 cm, made from ABS for impact resistance and durability. Lightweight propeller weight: about 4.8 g for easy rotation at low wind speeds. USB cable length: 1 meter for flexible placement of the bulb. Installation: propeller attaches to the generator and is aligned using positive and negative blade positions for correct rotation and stable mounting. Fine workmanship designed for reliable performance in educational and hobby settings. Benefits Teaches wind power concepts by turning wind into visible electrical output using the included USB bulb. Easy to assemble and operate, making it suitable for classroom experiments, hobby builds, and demonstrations. Compact and portable components allow quick setup and reuse in multiple projects. Durable materials reduce the need for frequent replacement during repeated use. Applications Classroom demonstration: show students how wind energy is converted into electricity and how generator output lights the USB bulb. DIY model turbines: integrate the generator and propeller into custom wind turbine models and small STEM projects. Handson experiments: test blade angle, wind speed, and generator load to explore basic principles of renewable energy. Package contents 1 x generator 1 x propeller (18 cm, ABS, about 4.8 g) 1 x USB cable, 1 meter 1 x 5watt USB bulb Notes Designed for educational and hobby use as a demonstration system. Follow basic handling instructions when assembling the propeller onto the generator to ensure correct blade orientation and secure mounting.
