This DIY STEM Oscillating Head Fan is a fun hands-on project designed to teach students and makers about mechanical movement, electric motors, and circuit assembly. By assembling this fan, you’ll learn how electricity powers a motor and how gears convert rotation into side-to-side oscillation — just like a real electric fan!

| STEM Fan Kit – motor, fan blade, and plates ready to assemble. |
Perfect for classrooms, STEM activities, or home experiments, this project combines creativity with basic engineering and electrical concepts.
🪵 Step-by-Step Assembly Guide
Step 1: Unbox the Kit
Open your DIY Science Kit and check that all 19 wooden plates, screws, motor, and wires are included.
 |
| All components included in the DIY STEM Fan Kit. |
Step 2: Build the Base
Assemble plates 1 and 2, then attach plate 3 on top to create the main platform.
 |
| Assemble plates 1 and 2. |
 |
| Attach plate 3 on top. |
Add plates 4 and 5 underneath as support brackets using screws.
 |
| Insert plate 6, ensuring it faces the correct direction. |
Step 3: Prepare the Motor
Attach two long phase wires to the motor terminals as shown in the diagram.
 |
| Connecting phase wires to the motor |
Assemble plates 7 and 8 to form the motor holder, then mount the motor using plate 9 and screws.
 |
| Assemble plates 7 and 8. |
 |
| Mounting the motor inside the holder. |
Step 4: Strengthen the Frame
Add plates 10 and 11 to the motor section and secure with screws.
 |
| Reinforcing the motor frame. |
Attach plate 12 on top to lock the motor in place.
 |
| Locking the motor securely with plate 12. |
Insert plates 13 and 14 onto the motor shaft and fix them firmly.
 |
| Mounting plates 13 and 14 onto motor shaft |
Step 5: Combine and Connect
Insert three plate No. 15 onto plates 7 and 10 as shown.
 |
| Adding plates 15 to strengthen the structure. |
Place the motor assembly onto plates 4 and 5, guiding the wires through the small hole.
 |
| Aligning motor assembly with base support. |
Use plates 16 and 20 to connect plate 6 and plate 13, then secure with screws and the orange spacer.
 |
| Connecting components using spacers and screws. |
Step 6: Wiring and Switch Installation
Install the battery box and switch, making sure the wires are facing the correct direction.
Tighten with screws to secure.
 |
| Battery box and switch connection, |
Step 7: Add Final Parts
Attach plate 17 and fix the fan blade onto the motor shaft.
 |
| Installing the fan blade on the motor. |
 |
| Fix the fan blade. |
Finally, add plates 18 and 19 to complete the fan housing.
 |
| Final assembly with plates 18 and 19. |
 |
| Check all parts. |
🔋 Testing the Fan
Insert the batteries, turn on the switch, and watch your fan spin and oscillate! You’ve now built a working STEM oscillating fan that demonstrates real-world mechanical movement and electrical control.
