🔧 Integration Tips for Makers & Engineers

Pair this blade with a small DC motor used as a generator to explore voltage output versus wind speed and load. It’s an excellent add-on for Arduino or Raspberry Pi data-logging projects using a microcontroller and sensor modules to measure RPM, voltage, and power.
Use a suitable 2 mm shaft coupler or press-fit on matching shafts
Combine with rectifier/regulator modules and supercapacitors for energy storage demos
Note: Output voltage and power depend on wind speed, blade RPM, and generator characteristics

🔬 Typical Applications

• Mini wind turbine systems and energy-harvesting experiments
• Hobby and STEM educational projects
• Small generator prototypes and science fair builds
• Mini fans driven by DC motors
• Experimental electricity generation prototypes

⚠️ Notes

• Ensure proper balance and secure mounting to prevent vibration at higher RPM
• Verify shaft size compatibility (~2 mm) or use an appropriate adapter
• Intended for educational and hobby use; not a weatherproof, long-term outdoor assembly
