Summer is coming and the temperature will rise. Because the temperature is hot, i will show you to make a air Conditioner from trash!. This is different from another DIY's Because i will make it from a old hairdryer fan, not use computer fan. Its more cool and more powerful!

Its easy to make!


  • Easy to use
  • Use AC supply or DC supply

Step 2: Materials You Will Need:

  • Old hair dryers (or anything with motors and propeller)
  • Super glue

  • 2 bottles
  • Cardboard or anything you want to make the case
  • And some creativity to make it

Step 3: Open the Hairdryer

  • Take the screwdriver, open the hair dryer and take apart the motors.
  • Open the motors holderlike image 6

Step 4: Take the Bottle Lid and Make the New Motor Holder

  • Take one bottle lid
  • Place the motor on middle
  • Make a hole with screwdriver like image 3
  • And cut triangle with cutter like image 4
  • and attach the motor to the new holder and reattach the propeller

Step 5: Cut the Bottle Neck

  • Cut the bottle neck with cutter
  • Make two
  • Glue with super glue like image 3 and add some tape to make it stronger
  • Close this with the new motor holder like image 5

Step 6: Next!

  • Glue the bottle neck with motor to the case like image 5 & 6

Step 7: Next Again!!

Step 8: The Electricity

  • Take the plug from the hair dryer

  • Glue the transformer to the case with super glue.
  • Solder the 12v output to the motor like image 6

Step 9: Test the Transformer and the Motor

Plug in the transformer to electricity and the motors will run.

Step 10: The Warm Air.

  • Take the hot element from the hair dryer and take the thin wire (Nichrome wire)
  • Take 2 screw and tie the nichrome wire to the screw
  • Take the switch from hair dryer
  • Make a simple circuit :
  1. Screw - switch - 6v/9v output
  2. screw - 6v/9v output
  3. Like image 6
  • And instal the switch to the case

Step 11: Electricity Steps Is Finish

This is all of the circuit . Now you need to make the upper case like image 2 and 3. Make a hole in front of the nichrome wire, and if you turn on the switch, the nichrome wire will heat and give you a warm air. But if you turn off the switch, this air conditioner will give you a cool air.

  • You can place it on bedroom, living room or any room you want!.

    I like the idea, simple and effective.

    However having a heating element in a cardboard case is, personally, a huge fire risk. By using a differnt case or hving the element in a fireproof enclosure this will work. Thak you for the 'ibble.
