Circuit Diagram
Reference the orientation of the USB Type A connector. The voltage wire is connected to the pin on the far right. The ground wire is connected to the pin on the far left. The fan can be powered by any 5V USB hub or 5V USB Battery.
USB Type A Connector
Get the USB connector, shell and strain relief plug ready. The USB connector will be soldered to a piece of 2-wire ribbon cable.
Wire for USB Connector
Peel and cut a piece of 2-wire 11in(28cm) in length from the 10-wire ribbon cable.
Wire Tinning
Using wire stripers, remove a bit of insulation from the tips of each wire. Third helping hands can be used to hold wires in place while soldering. Tin the tips of each wire using a bit of solder. This will help prevent the strands of wire from fraying.
Solder USB Connector
Tin the pins on the far left and right of the USB type A connector by adding a bit of solder. Attach the two wires to the pins on the USB connector. Reference the photo for correct polarity.
Install Shell
Insert the wire into the strain relief plug and pull the wiring all the way through. Install the shell by threading the wire through the hole.
Wired USB Connector
Press shell through the USB connector to install. Pull strain relief plug through the hole.
Wire Fan
Cut the wire from the fan short or to your desired length. Solder the wires from the USB connector to the 5V fan. Double check polarity is matching and correct. Use pieces of heat shrink tubing to insulate exposed wired connections.
