Intro: How to Make a Simple Portable Fan
In this Instructable I will show you how to make a simple portable fan. Warning before taking apart the computer power supply you must unplug the power supply or else you could be really painfully shocked or even killed just from touching one of those silver plates which are heat sinks I learned that first hand but luckily I wasn't killed. You should also use a grounding wrist band with a built in resistor and make sure you keep your hands and tools away from the big black things, they are capacitors which can still hold a charge of about 200 volts at 5 amps which can easily injury or even kill you!! I am not responsible if you get injured or killed. But you can easily overcome this by using a different fan from inside your computer.
Step 1: Getting the Materials
Here is a list of things you need to make the fan:
One computer power supply or one computer fan (if you are using a computer fan then skip steps 2 and 3 )
Eight AA batteries
One battery holder for eight AA batteries
One Phillips screwdriver
Step 2: Take Apart the Computer Power Supply
First remove the four screws on top of the power supply. Then lift the cover off of the power supply.
Step 3: Remove the Fan From the Computer Power Supply
Cut the two red and black wires with the side-cutters then remove all four of the screws that are labeled in the second photo. After that take out the fan then go onto the next step.
Step 4: Build the Portable Fan
Now you have to put the batteries in the holder. After that is done you tape the fan to the battery holder.
Connect the wires as shown in the fourth photo then test it out and you're done. If you have any questions about this build please feel free to ask and don't forget to vote for me for the "Dead Computer Contest".
