Desktop Fan





Introduction: Desktop Fan

In this instructable, i will show you how to make a fan for your desk out of things you might have aroung your house.

Step 1: Step 1: Gather Parts

You will need:
Computer fans
Hot glue gun
Hot glue
Soldering iron
Toggle switch ( see picture )
Posicle sticks
DC adaptor
Resistors and LED ( see picture )
Your hands
Cable ties

Step 2: Step 2: Design

Start by making a design for the fans to sit on, then glue it together.

Step 3: Step 3: Glue

Now glue 3 fans on the bottom.

Step 4: Step 4: More Glueing

Now gluse popsicle sticks over the fans.

Step 5: Step 5: Even More Glueing

Now gluse fans on top, try to make a pyramid form, i would have but i ran out of fans.

Step 6: Step 6: Glue Switch

Now glue the switch somewhere convenient.

Step 7: Step 7: Solder Part 1

Now solder the positive wire from the converter to the middle of the switch.

Step 8: Step 8: Solder Part 2

Now solder all of the negative wires ( from the power supply and fans ) together.
Then solder all of the fan wires to the bottom odf the switch.

Step 9: Step 9: Solder Resistors

Now solder the resistors in parallel, then solder a wire to each end.

Step 10: Step 10: Solder Finale

Now solder the positive lead to one wire from the resistors, and the other wire from the resistors to the last connection of the switch. Also solder the negative LED lead to the negative wires. It will be somewhat like in the picture.

Step 11: Step 11: Secure

Now glue the LED to somewhere visible, and secure the wires out of the way however you see fit.

Step 12: WARNING!!!!!!!!!

Careful! Before you test this device, mind your fingers! The fans will sping extremely fast, i foun out the hard way! They will chop up your finger like a hot knife through butter!

Step 13: Video

This is a video of the fan.

Step 14: Mods

There are several modifications you can meke, such as number of fans, size, led and switch.
BUT! You may want to add some weight at the base, when i tried this, it nearly took flight!

are you from the uk?

great ible

No, I live in Canada. Thanks BTW!

where did you get all of those?

Long story short, My auntie moved out and I'm an only child ( YAY! ), so i have a second room full of old computers, radios, basically anything you can think of. It's great for making"green" inventions by recycling.

Since i have posted this, i have noticed the LED overheat. You may want to use strronger resistors

Or you could remove the LED from the circuit all together. A power indicator LED is unnecessary, because you can pretty much tell its on or not by looking at it.

True you can remove the led, i did that for now, but you misunderstood. if you are the forgetful type, it is to tell you if it is plugged inor not. thanks for the comment.

So the LED stays on whether the fan is running or not? Cause if it doesn't, then I didn't misunderstand you and its redundant cause you can see with your eyes if the fan is moving or not.
