Design and Electronics of a DIY Wind Tunnel for the Laboratory of Making Course - AA.2024-2025
This project provides instructions to build your own DIY Wind Tunnel — a compact, low-cost tool designed for aerodynamic testing and experimentation. It combines a custom-built physical structure with an electronic control system, including an LCD screen for feedback and smoke visualization for airflow studies.
Whether you're a student, maker, or educator, this wind tunnel offers a great platform to explore fluid dynamics, test model designs, or simply get hands-on with STEM.
-
✅ Adjustable Wind Speed
Control the airflow using a potentiometer to simulate different wind conditions. -
🛑 Emergency Stop Lever
A manual kill switch immediately stops the fan for safety during testing. -
📺 Live Session Feedback on LCD
The LCD displays useful information such as session duration, fan speed level, and system status. -
🌫️ Smoke Generator
For visualizing airflow over objects placed in the tunnel. -
📱 Optional Smartphone Mount
A built-in holder allows you to record experiments directly from your phone for later analysis.
- Aerodynamics experiments
- Model testing (e.g., cars, airfoils)
- Educational demonstrations
