If you like to enjoy your time outdoors, for example at a campsite, but find yourself frustrated with the difficulty of recharging your electronic devices, a good alternative to generators is to harness the energy provided by the wind. If you are interested in the idea, we will show you how to make your own wind turbine which, although it does not stand out for its power, will give you enough independence to recharge your batteries.
Materials and tools: portable wind turbine.
To get to work you will need a few tools, such as a welder, hammer, pliers, a good cutter, voltmeter, pliers and a lathe or equivalent.
The materials that, in principle, can be found in any DIY store are:
- T-shaped seal.
- A 1 ” ABS bar.
- PVC coupler.
- ABS sheet.
- Stainless steel wire.
- Hex bolts.
- Insulating cable.
- Electrical tape.
- Spray the color you wish to paint.
Step 1: Assemble the motor.
The central body has six holes drilled the same distance around the ABC bar that the screws that the blades will insert go into. While you can choose what works best for you, three blades may work better than six.
Drill a hole axially in the center of the part so that you can fit the end of the motor, which is shaped like a corkscrew. After the operation, glue the bar on the engine. Make sure you insert it far enough that the wires are visible from the bottom of the T-joint. Once the motor is perfectly positioned, glue the two components together.
The next step will be to solder the cables to the motor cables, making sure they are large enough to extend the length and height of the device. Then place the connector with the underside of the T-joint. At the other end of the joint, cut a slot to fit the tail.
Step 2: Blades.
For this project, a turbine with three blades was chosen, each about 17 centimeters long and just under 5 centimeters at the widest point.
Following this example, cut the boards out of ABS sheet less than a millimeter thick and sand the edges to remove any irregularities. You can paint the blades in a striking color, so that they stand out from the rest of the device. Drill a 1/2 ” hole in the base of the blade, then secure it in the center of the system with a hex screw.
Reproduce the process with the tail piece. Keep in mind that in this case you will need to cut two of the same sheet and of the same thickness. Then glue them together so that they fit perfectly into the groove you made in the T-joint.
Step 3: Create the foot of your turbine.
Cut about 12 inches from the aluminum tubing, then cut four equally spaced slits at one end. These indentations should be about 3 centimeters deep. Now cut two rectangular pieces of foil and make grooves again, this time about half of them. These should fit snugly and extend about an inch beyond the pipe.
The next thing to do will be to cut 8 of these pieces, about 2.5 centimeters wide and about 30 long, and make three holes in each of them: one at the end and the other about 10. centimeters from the ends.
In place of the nearest holes, cut a rounded corner so that the legs can be bent along the aluminum pipe. Fit the 8 pieces in pairs at each corner of the cross member that is on the metal tube. The hole made at ten centimeters will be used to fix the feet.
Step 4: Paint.
After all this hard work, this step can be one of the most satisfying. Just choose the color you want and spray it on. You can opt for one or two coats of paint, your choice.
Step 5: Fixing the turbine.
For your turbine to be ready, there will only be one step left: make sure it has a good anchorage to the ground. So, cut the 3 millimeter steel wire to about 10 centimeters in length. At about 7 centimeters, fold it triangular to anchor it. This can be a difficult task, so don’t despair.
Leave the triangle open at its lower end so you can insert it into the piece that forms the foot. Also, make sure there is something loose enough to open and close.
Step 7: final exam.
At this point, all you have to do is install the turbine and turn it on. You can check if it is activated with a simple hair dryer and if it is, you will have your homemade solution ready. With it, your work and the wind, you will have an alternative solution to power your rechargeable batteries or similar systems.
