Introduction: How to Make Small Wind Turbine Homemade
So here we are going to make a small wind turbine. You can make it easily at home. Almost 90 percent of the parts are made of PVC fittings and pipes. So it is very easy to assemble or disassemble and carry it to your classroom. I have uploaded my own video making this small mini wind turbine on youtube. I have also embedded that here. Let's make it. watch video you can learn it on my blog here Make small wind turbine

Step 1: Step 1: Making Propeller
Buy a 10 inch PVC Pipe (3inch in diameter)
equally divide the edge perimeterCut the pipe into blades as shown in video- watch video
Make holes as shown in the picture on anything round in shape with 2.5 inches.
Then screw 3 blades to it using cycle screws.
Step 2: Step 2: Making Wind Turbine Base
The turbine base and the post holds the propeller, dynamo, tail, and autorotation mechanism. It is very easy to make the turbine base. Buy some PVC fittings.

Step 3: Step 3: Make Small Wind Turbine Tail
Most of the DIY wind turbine videos on youtube doesn’t have a tail- autorotation mechanism (yaw mechanism). Without a tail-autorotation mechanism, a Small wind turbine is not complete. What is the purpose of a tail? The tail auto rotation mechanism will help the propeller to change the direction to face the wind. Th tail will force the propeller to face the wind even at higher wind speeds.

Step 4: Step 4: Making Dynamo Casing
A piece of pen
PVC Fitting T
Buy 2 bearings
Buy a dynamo 3V
Connect the dynamo to the PVC fitting.
Connect the two bearings to a common axis.
A piece of a pen can be used as the axis.
connect one bearing to the PVC T
Step 5: Step 5: Mini Wind Turbine Is Ready
Place the wind turbine in front of a fan
connect a multimeter to the output wires of the dynamo.Yes, Multimeter needle is indicating a current flow through it. If you are using an efficient Dynamo, you can use this dynamo to charge your 3 v rechargeable battery. Besides, You can build a larger wind turbine than this to charge your smartphone too.
