Homemade mini wind turbine diy for school students and Teachers. This demonstration video uses simple components and is intended to be used for a school science project. Components used are pvc pipe & fittings, plastic bottle & styrofoam (thermocool). List of items which we used in this project is listed at the end of this article.
I have also made a real vertical axes wind turbine from scratch and it is available on my YouTube channel. If you want to see then [click here].
of Mini Wind Turbine DIY
Here are some pvc fitting of 3/4 inch like elbow, tee, socket and piece of pipe. Assemble them as shown in the below image. The large pvc pipe will be the stand of this mini wind turbine project. All pvc fittings are used of 3/4 inch dia. You can make the base of any width and length that is why I did not provide any measurement.
Fix the socket in the large piece of pipe and insert into the tee to make the main post. Where the turbine’s upper portion fits. Remember, the tee has already a piece of pipe inserted into.
Take 4 to 6 inches dia pvc pipe in 12 inches length and mark the blade shape in a little bit cross of pipe. And then cut 3 pieces with hacksaw or a mini grinder as I did.
The triagle piece in top-left image, is cut from a plastic hard sheet. It is used to fix the 3 blades with nut & bolts. Then fix it with the dc motor, as shown in the following right image. Choose DC motore which can generate minimum 3 volts on minimum rpm.
Fix one socket with tee with the help of a piece of pvc pipe and insert DC motor into it from back side and pull its wires downward from the center hole the tee.
After inserting the dc motor, it will look like the following image.
Cut the tail shape from a flat hard plastic sheet and fix it with the end of pipe.
I used a plastic bottle to cover the upper dc motor part and for better look like a real turbine. This part is not mandatory.
I also used white spray paint to hide the entire components inside.
Connect and solder the wires of DC motor to a led panel of 3 volts. And also I used a 12v on/off switch in between and fixed both of them to the main post.
After fixing all item on the post, insert it into the center hole of upper tee to hold the turbine.
Testing the project
After completion, It will look like the following image.
Put this project in the top place where heavy wind is available. I demonstrated it inside the room and used an electric blower to provide enough air.
Production of voltage depends upon the dc motor generator. I took this motor from an old electric toy motor bike.
I hope you will enjoy the project. Please share this post among your friends or students. Thank you so much.
