USB Fan

Materials you need for this project:

- FAN (from old computer)

- Piece of cable

- USB connector (or cable, then also use red/black wires)

- Switch

- 2x 3/16 inch screw and bolt

- Shrink tubing

Tools you need:

- Hot Glue gun

- Soldering iron

- Pliers

- Hot air gun

I used an old 12V DC fan from a scrap computer.

You can also buy them on E-Bay for a few dollars.

Cut out the plug of the fan, then remove the yellow cable.

Yellow cable is used for measuring RPM.

I attached the screws to the top to get a proper angle.

By using different lengths you can determine a good angle.

Glue the switch on the fan housing with hot glue.

start with the stripping of the cable.

I used the red and purple wire from a universal cable (when using USB cable you need red and black wire).

Connect the red (+) wire of the fan with the switch.

Connect the red (+) wire of cable with the switch.

Connect black wire from fan with the purple (black USB) wire from cable.

Use shrink tubing to work it off.

Now solder the red cable to the +5V terminal and the purple (black USB) wire to the GND terminal.

Use shrink tubing to work it off.

USB Fan is now ready!
