Homemade USB powered small fan USB fan DIY production tutorial
It is simple and easy to make your own mini fan powered by computer USB. In such hot weather, let’s make one to cool down~
Making materials: red wine cork, CD, USB data cable, small engine, conductive wire, nails, paper roll, scissors.
Cut the disc from the edge to the center to make fan blades.
Cut out 8 equal parts of the fan blades. After cutting, twist the fan blades slightly in the same direction. The inward part is consistent with the direction of motor rotation. Be careful not to use too much force or it may break.
The completed fan blades are similar to those of an electric fan.
Poke a small hole in the center of the wine cork.
Insert the red wine cork into the inner circle of the disc and secure it.
Modify the extension head of the USB extension cable and solder the positive and negative wires separately.
Connect the wires to the connectors, and also connect the motor wires, ready for assembly.
The wire is connected to the small motor inside the paper roll (bracket).
The bottom of the roll is glued together with another complete disc to create a base. The motor is inserted together with the fan blades.
When the USB cable interface is plugged into the computer, the mini fan starts to rotate, bringing us coolness (^o^)/~
