How do you make a mini fan for a project?

• 1
  
  Build a set of fan blades which attaches to the armature on your motor. For example, cut a piece of cardboard so that it has symmetrical blades, or make a CD blade as outlined in the "CD Blades" section. Make a hole you can attach to the armature on the motor.
• 2
  
  Build a small stand out of wood or coat hanger so that you can mount the fan blade and point it toward you when in use. Mount the motor on top of the stand.
• 3
  
  Glue or tape the fan blades to the armature of the motor.
• 4
  
  Attach wires to the positive and negative terminals of the motor. Push the bare ends of the wires through the terminals on the motors, then twist the bare wires back around themselves.
• 5
  
  Attach the wires to a power source. Tape or glue them to batteries, with the positive terminal on the positive end of the battery, and vice-versa. Alternately, strip the USB wires with the male end, then cut off all except for the black and red wires. Attach the red wire to the positive terminal on the motor, the black to the negative.

CD Fan Blades

• 1
  
  Cut eight lines into the CD at regular intervals, cutting only the shiny part, but not the clear plastic ring in the middle.
• 2
  
  Light the candle and hold the clear plastic ring over it. This will warm up the CD allowing you to bend and twist it. Bend all of the blades to about a 30-degree angle. Don't hole it over too long or it will melt completely. You may need to spin the CD over the candle a few times to successfully make the shape. Hold the CD and let it cool for a few minutes.
• 3
  
  Piece the center of the cork with a needle to create a hole for the armature. Use a needle about the same size as the motor's armature.
• 4
  
  Push the cork into the hole in the center of the CD. Glue the cork into place, and you now have a device you can attach to your motor.
