How to Make a Windmill But Shown As a 3D Design Because This Was Made During Lockdown

Look, I know this tutorial may not be of much help to you since it was made during lockdown and I did not have the materials at home to actually make a windmill. So I had to improvise. What you will see below in the images that I have put in and above in the video is that I have shown the steps of how to make a windmill in 3D design. The 3D design images are just there for the visual element and I will try to be as extensive as possible when going through the steps.

For this project you are going to need:

- Some 9 mm plywood Two axes (size depends on what fits into the ball bearings)

- A motor to be used as a dynamo

- A ball bearing drill A LED (unless you want the motor to power something else)

- Two ball bearings

- A saw

- Some glue could be useful

When I say rotation pad I mean the thing on the bottom of the windmill that lets it move. This is so the windmill’s fin can direct it towards the wind so that it produces as much power as possible. This mechanism is extremely simple. All you need is two slabs of some wood.

1. One of which (preferably the bottom one) will be drilled into.

2. You then put one of the ball bearings in and glue it so that it can move around freely.

3. Then you attach one of the axes to the center of the other slab so that the two can be connected. Hopefully, like this the upper slab can spin freely.

4. Make sure that both the ball bearing and the axis are as central as possible so that the windmill doesn’t move when it spins.

1. Now you should get the 9mm plywood (it’s fine if you used it for step 1 too) and cut it into two triangles. You can also cut it into other shapes but I recommend triangles. These triangles should be around 30cm tall.

2. You drill a hole into one of the two and glue the ball bearing into it.

3. Attach the dynamo to the other triangle so that if you look through the ball bearing hole you can see the middle of the motor.

4. Now cut out a piece of wood shaped like a fin and attach that to the back.

5. You now take these two parts and align them on the top of the rotation pad to make sure that they are attached to it so that they don’t fall off.

1. Cut out four rectangular pieces of wood.

2. Cut out a circle or a square for these blades to be attached to

3. Attach the blades at a 45° angle so that when the wind hits them they move.

4. Glue the axis to the circular or square piece of wood and put it through the ball bearing on the windmill’s body

5. Connect the axis to the motor so that when the blades spin the motor creates energy.

Basically the windmill is done now but I like to add something else to it to make it look nicer. What I planned to do was to draw a robot and then attach the LED to its head to make it look nice. You don’t have to do this. You don’t even need to have an LED as a load. If you do choose to do something else with the electricity though you will need to adjust the resistor. For an LED about 100 ohms is good but I am not sure about any other loads.
