DIY - Electric Handheld Fan
Intro: DIY - Electric Handheld Fan
There are times when you would trade your kingdom for a fan. During the hot, muggy climates, waiting for long in ticket lines, the intense heat and humidity can make one feel irritated, sleepy and snappy. In this instructable, i decided to make DIY Electric Handheld Fan. It is a mini portable electric fan that can be made very easily and can be a useful gadget in situations mentioned above.
I agree that my electric handheld fan in not very attractive as compared to the products available in the market but it does perform well when needed.

From Home & local Store: Plastic Sheet, Connecting wires and Scissors.
Note: I used the propellers from an old toy lying around my house, however the small propellers available with the motors are also effective.STEP 3: Let's Get Started
- Take a plastic sheet and draw a large peanut shape as shown in the image.
- Cut the plastic sheet carefully and make two identical pieces.
- Measure the dimension of motors and toggle switch.
- Make holes for both the parts in the plastic sheet as can be seen in the attached images.
- Insert the motors in the holes made in plastic sheets and secure the motors with hot glue.
- Attach the propellers to the motor shaft.
STEP 4: Make the Battery Holder
I used a 18650 li-ion battery as the power source for the electric fan. You can get a 18650 holder from the market or can make one easily at home.
Refer to my instructables on DIY 18650 Battery Holder to make a battery holder at home. If you prefer visuals, you can also watch my video tutorial to make a 18650 Battery holder.
STEP 5: Assemble Parts and Make Connections
- Using the toggle switch, assemble both motors and the battery holder with eachother to form the electric hand held fan as shown in the attached image.
- Connect both the motors in parallel, so that they both move in same direction when powered ON.
- Connect a switch between the motors and the battery holder.
- Refer to the schematic to make connections.
STEP 6: Testing and Possible Upgrades
Our DIY Electric Hand held Fan is ready. Insert a 18650 Battery in the holder and press the switch to turn ON the fan.
Although there are many upgrades possible (suggestions are always welcome in comments section) but i thought of few useful upgrades that would make this gadget at par with the products available in the market.
- Adding a TP4056 Charging Module: Using this module the battery can be easily charged without any need to remove it from the battery holder.
- 3D printing an Enclosure: it is also possible to design a beautiful enclosure and print it using a 3D printer at home.
- Adding Variable Speed control: This additional feature can be easily provided just by connecting a potentiometer between the battery and the motors.
So friends, this here concludes the instructable. In case you might have missed, have a look at the video to see how i made the Electric Handheld Fan at home. Stay tuned and don't forget to Follow my instructables to receive regular updates.
Thanks for Your Support..!

I need a fan like this.

Really?
It is quite simple to make, however, If you plan on making this i would suggest you to use a mini quadcopter like propellers instead of any other. They help in blowing a lot more wind.
