Frequently Asked Questions
Q: What power source does the DC 3-5V DIY Blow Fan Kit require?
A: The kit operates on DC 3–5V, making it compatible with standard USB power sources or a battery box (available as a separate variant). This low-voltage design makes it safe and easy to use for educational projects.
Q: Is this DIY fan kit suitable for beginners and kids?
A: Yes! The DC 3-5V DIY Blow Fan Kit is designed for self-assembly and is ideal for students, beginners, and young makers. It's a great introduction to basic electronics and aerodynamics concepts. Adult supervision is recommended for younger children during assembly.
Q: What does the "floating ball technology" mean in this kit?
A: The 130 high-speed motor drives a blower fan that generates a focused column of air. When a lightweight ball is placed above the airstream, the air pressure keeps it levitating — a classic demonstration of Bernoulli's principle used in science and physics education.
Q: Can I use this kit for a school science fair project?
A: Absolutely! This DIY wind turbine and floating ball kit is a popular choice for science fair projects, STEM demonstrations, and classroom experiments. It visually illustrates airflow, motor mechanics, and fluid dynamics in an easy-to-understand way.
