AN USB DESKTOP FAN

This is my third blog and i am gonna show you how to make a USB DESKTOP FAN.

THESE ARE THE COMPONENTS YOU REQUIRE

STEP 1 :

Cut off the USB cord as close as you can get to the end that doesn't go into your computer. If it has one of those cylinders chop that off too. Cut off the jack to the fan. Strip all wires. Find out which wires are power on the fan by using the 9 volt to test different wire combinations. Remember that you might have the right wires but have them backwards, and then it wont spin, so try each combo both ways. If the fan spins, those two wires work . Once you find the two wires, cut off any other wires.To test the USB cord plug one end into the computer and use the multiplier to test different combinations of wires. Mine was black and red, but i don't know if all cords are the same, but test those two first anyway. Once you find the two power wires, fold down

the others onto the cord itself and tape around them, like the picture.




STEP 2 :

Use the small wire nut to connect the two red wires. Put the switch in by attaching one black wire to one peg and the other black wire to the other peg. You can also have the reds on the switch and the blacks connected, it doesn't matter as long as the colors are the same. After you get the wires on the switch, you can solder them on( i used hot glue because i still need to work on my soldering). once you have done that, use a band of electrical tape around the fan to attack it all. make sure you attach it so the switch is pointing the same way the fan will blow.

STEP 3 :

Once you have everything put together except the stand, you need to test it. Plug the cable into a USB port and flick the switch. The fan should blow in the direction the switch is pointing. If something doesn't work, tinker with it until it does.


STEP 4 :

Use pliers to unwind the wire hanger. cut off the bottom bar so it is 17.5 inches long. I don't like to type long things, so i put pictures in chronological order. just use a ruler for measuring and needle nose pliers for bending



YOU ARE DONE!
