What You’ll Need: The Supply List
Before we dive in, let’s gather our supplies. Here’s what you’ll need to build your very own cardboard table fan:
* Cardboard: Lots of it! Think old boxes from deliveries, cereal boxes, or anything sturdy enough to hold its shape. The thicker, the better.
* Small DC Motor: You can salvage one from an old toy, or purchase one online. A 3-6V motor works perfectly.
* 9V Battery: To power our fan.
* 9V Battery Connector: This will allow us to easily connect the battery to the motor.
* Switch (Optional): A small on/off switch is handy for controlling the fan without disconnecting the battery every time.
* Wire: For connecting the motor, battery connector, and switch (if using).
* Hot Glue Gun and Glue Sticks: Our primary adhesive for this project.
* Craft Knife or Scissors: For cutting the cardboard. Be careful!
* Ruler or Measuring Tape: For accurate measurements.
* Pencil or Marker: For marking our cuts.
* Compass or Circular Object: To draw circles for the fan blades.
* Safety Glasses: Protect your eyes from cardboard dust and hot glue splatters.
* Soldering Iron and Solder (Optional): If you’re using a switch, soldering the connections will make them more secure. You can also use wire connectors or simply twist the wires together and tape them securely.
* Decorative Materials (Optional): Paint, markers, stickers, etc., to personalize your fan.
Building the Fan Base: A Solid Foundation
The base is crucial for stability, so let’s start there. We’ll create a sturdy box-like structure to house the motor and battery.
1. Cut the Base Pieces: Cut out six pieces of cardboard according to these dimensions:
* Bottom: 6 inches x 6 inches
* Top: 6 inches x 6 inches
* Sides (4 pieces): 6 inches x 4 inches
2. Assemble the Box: Using your hot glue gun, glue the four side pieces to the bottom piece, forming a box. Make sure the edges are aligned for a clean look.
3. Attach the Top: Glue the top piece onto the box, closing it up. Leave one side partially open for now – we’ll need access to the inside later.
4. Reinforce the Base: For extra stability, cut out small cardboard triangles and glue them into the corners of the box, both inside and outside. This will strengthen the joints.
5. Create the Motor Mount: Cut a small square (about 2 inches x 2 inches) in the center of the top piece of the base. This is where the motor will be mounted.
6. Secure the Motor: Place the motor in the square hole. You might need to adjust the size of the hole to ensure a snug fit. Use hot glue to secure the motor in place. Make sure the motor shaft is pointing upwards.
7. Close the Base: Now, glue the remaining side of the top piece to fully close the base.
Crafting the Fan Blades: The Heart of the Fan
Now for the fun part – creating the fan blades! We’ll use cardboard to make lightweight but effective blades.
1. Draw the Blade Circles: Using your compass or a circular object, draw a circle on a piece of cardboard. The diameter of the circle should be about 6 inches.
2. Cut Out the Circle: Carefully cut out the circle using your craft knife or scissors.
3. Divide the Circle: Draw lines from the center of the circle to the edge, dividing it into four equal sections.
4. Cut Along the Lines: Cut along each of the lines, stopping about 1 inch from the center of the circle. This will create four flaps.
5. Bend the Blades: Gently bend each flap in the same direction, creating a slight angle. This angle is what will catch the air and create the airflow. Experiment with different angles to see what works best.
6. Attach to the Motor: Carefully attach the center of the fan blade circle to the motor shaft. You can use hot glue, but be careful not to get glue inside the motor. A small dab of glue is all you need. Make sure the blades are securely attached.
Wiring It Up: Powering the Fan
Time to connect the motor to the battery and bring our fan to life!
1. Connect the Battery Connector: Attach the red wire of the 9V battery connector to one of the motor terminals. You can solder it for a secure connection, use a wire connector, or simply twist the wires together and tape them well.
2. Add the Switch (Optional): If you’re using a switch, cut the black wire of the battery connector. Connect one end of the cut wire to one terminal of the switch, and the other end to the other terminal. This will allow you to turn the fan on and off.
3. Connect the Remaining Wire: Connect the remaining wire from the motor to the black wire of the battery connector (or to the switch, if you’re using one). Again, solder, use a wire connector, or twist and tape the wires securely.
4. Test the Connection: Insert the 9V battery into the battery connector. The fan should start spinning! If it doesn’t, double-check your wiring connections.
5. Secure the Battery: Place the battery inside the base of the fan. You can use hot glue or tape to secure it in place.
Adding a Fan Guard (Optional but Recommended): Safety First!
To prevent accidental finger injuries, let’s add a simple fan guard.
1. Cut the Guard Pieces: Cut out several strips of cardboard, about 1 inch wide and long enough to reach from the base to slightly above the fan blades.
2. Arrange the Strips: Arrange the strips around the fan blades, creating a cage-like structure.
3. Glue the Strips: Use hot glue to attach the strips to the base and to each other, forming a secure fan guard. Make sure the guard doesn’t touch the fan blades.
Personalizing Your Fan: Make It Your Own!
Now that your fan is functional, let’s add some personal touches!
1. Paint the Base: Use acrylic paint to decorate the base of the fan. You can choose a single color, create a pattern, or even add some artwork.
2. Decorate the Blades: Use markers, stickers, or paint to decorate the fan blades. Be careful not to add too much weight, as this could affect the fan’s performance.
3. Add Stickers: Stickers are a quick and easy way to personalize your fan.
