This Mini Fan as been made out of a broken toy car's DC Motor. It works very well and is good to use it when you are working on your PC. The speed of the Motor is good and it does not heat up because of the 470pF capacitor used.
The tilt of the Fan blades determines the amount of air flow.
The Fan Blades is tilted at an angle of 45 degrees.
Step 1: Parts of the Fan
To make the stand of the Fan I have used the following items.
A piece of PVC cut out of a face powder container to make the fan blade.
A small PVC Box with weight inside to make the Base of the Stand.
A metal door handle is used to increase the height of the stand.
Attached to it is a wooden batten with Mortise Tenon joint to facilitate the movement of UP of Down.
Two pairs of Nut and bolt.
A thin PVC sheet to hold the Motor in place.
Two thumb nails to keep the Electrical wire in place.
Four tin screws are used fix the door handle and the wooden batten.
Step 2: Front View
This is the FRONT VIEW.
The total height is 9.5 inches or 24 cms.
To make the Fan BLADES take a piece of thin PVC sheet and draw the outline of the Blades.
Cut out the Blade with a hole in the center.
Dip one side in boiling water and twist it clockwise.
Do the same to the other side.
The FAN BLADE is ready.
Step 3: Back View
Here you can see that a 470pF capacitor has been used and connected to the two terminals of the Motor.
Thumb Nails has been used to keep the wires in place.
