Build an Electric Fan

Have you ever needed an electric fan? Well know you can make one with a few simple bits that you can find at most good hardware stores! Whatever you want to use it for, be it as to cool you down, or maybe to cool you prized gaming setup, following these simple steps will help you reach your goal.

Steps

  1. Take your fan blades and ensure they have a small hole or some way of attaching them to your motor.
  2. (optional) If there is no suitable way to attach them, use a small drill to make a hole that the motor spindle can fit through.
  3. Once you are sure that the blades can be attached to the motor, fit the motor into your casing, with the spindle poking out so the blades can be attached.
  4. Fit the battery in the same case.
  5. Connect the motor to the batteries and check that the motor works with the battery and that the motor is spinning the right way.
  6. Seal the case. If it doesn't clip together, you may need super glue or use some other method to stick it shut.
  7. Attach the blades. You could clip them on if there is a tight fight, or you may need super glue.
  8. CONGRATULATIONS! You have now made your own electric fan.
  9. Finished.

Tips

  • If you clip the blades onto the motor spindle, you may want to use blue tack on the top of the spindle to add extra support to the blades.
  • If the motor is spinning the wrong way, wire the battery to the opposite pins on the motor.
  • To check that the motor is spinning the right way, you might want to attach the blades temporarily with blue tack.
