Spring is here and summer is right around the corner. I don't know about you, but somedays, it gets really hot in my room. I don't have a fan, so I decided to make one. It's very simple, and you can build it in a day! Just follow the steps below and you can say goodbye to the extreme summer heat! Plus, since we're all indoors right now, it's nice to get off the computer and do some creative hands-on work:)

Supplies

All you need is:

Hot Glue Gun (with glue sticks)
Cardboard
Strong Cardboard Tube
DC motor - most other motors will work (the stronger the better)
3 Alligator Clips
2 - 9V Batteries
Pencil
Exacto Knife/ Something sharp to cut Cardboard
Tape
Electrical Tape
A little bit of patience when you're cutting the cardboard

Step 1: Make the Electrical Circuit

First, we will make the circuit. This is a very basic circuit. Attach 2 alligator clips to both the leads of the DC motor. Take the wire connected to the red lead to a negative terminal on the battery. Use the other wire connected to the blue lead, and attach it to the positive terminal of the other battery. Connect the positive and negative terminals with another wire. For now, you can leave it disconnected in one part so the battery isn't wasted. We will put electrical tape over all the connections later so that they don't touch, and they stay on.

Step 2: Sketch on the Cardboard

I made my basic sketches on the cardboard so that I know where to cut. For the blades of the fan, I chose a shape and tried to draw the same size around the circle. You can choose whatever shape that you would like to make the blades.

I also made 2 4x4 in squares for the base of my fan. I outlined it in sharpie so that you can see it better. (It's not in the picture, but trace a hole the size of your tube so that when you cut it out, it will fit right in.

Step 3: Cut It Out

We made all the sketches and drawings, so now we can cut it out. I recommend using an Exacto knife rather than a scissor because your cuts will come out much cleaner. Also, it will be much faster.

Don't try to rush when you're cutting so that you don't make any mistakes. It's important to have a good looking creation:)

If you don't have a strong cardboard tube, Use a kitchen roll or other cardboard tube and just make it stronger with what you have.

Step 4: Assembly Time!

Now that we have everything ready, it's time to put it together!

First glue the 2 squares of cardboard on top of each other. Make sure the one with the hole is on top.

Make sure it dries before continuing!

Next, take your tube, put a little ring of glue on the bottom, and stick it in the hole.

Use Electrical tape and secure all the connections so that it doesn't short circuit and it stays on.

I didn't have a switch lying around, so instead, I'm going to keep 1 wire from the motor disconnected so whenever I want the fan on, I can connect it. Otherwise, it will be off. If you do have a switch, just add it to your circuit.

I taped mine on the bottom. AND THEN... YOU'RE DONE!!!! YAY!
