Making a cone and blades for a fan with your own hands

The fan is a simple electrical device that consists of a motor, a cone stand, blades, and buttons for adjusting the frequency of operation. In some homemade fan designs, there may also be a backlight and a clock.

This article will provide instructions on making the cone and blades for a fan at home.

Here’s an example of a homemade fan with custom blades

Several suitable materials

There are numerous options for suitable materials when it comes to creating fan blades and cones:

1. Plastic base – this is a popular choice among designers for building fan-like devices. The blades are made from the upper section of a plastic bottle, specifically the part close to the neck. The remaining portion, up to the cork, is cut off. Additionally, a plastic bottle can be utilized to construct the cone and the base of the fan. The second part is typically created from the bottom of the plastic bottle. Occasionally, additional components such as drinking straws or cardboard may be necessary.

There are instructions available for making blades and a cone for the fan using each of the materials mentioned earlier.

From plastic

Let’s explore a step-by-step guide on how to transform a plastic bottle:

1. To start, we will utilize one part of the plastic bottle along with its cap to create the blades. To achieve this, carefully cut the base in a manner that forms several petal-like shapes. Remember to remove the petals alternatively.
2. Next, we will shape the blades by twisting them. You can conveniently do this by utilizing a candle, matches, or a lighter. However, exercise caution during this process as soft plastic is prone to catching fire. It is advisable to maintain a safe distance between the lighter and the plastic, just enough to heat it without causing any harm.

Now let’s take a look at the instructions for using a cooler:

1. In order to turn the cooler into a ventilating device with a propeller, you will first need to prepare the wires and the connecting structure. If the device is located near a computer unit, an ordinary USB cable will come in handy. Start by cutting and removing the insulation from the connecting wire. Repeat this process with the wires of the cooler. During the assembly, you will need a red and black wire for the propeller. The red wire is responsible for the positive connection, while the black wire is for the negative. However, if there are other colors in the wires of the cooler and USB cable, you can cut them off and discard them. This will help avoid confusion.

When it comes to installing the cooler on the plastic base, there are a few steps to follow:

1. Firstly, ensure that both the wires and the cooler itself are free from any dust or debris. It’s best to give them a thorough clean before proceeding.
2. Next, make sure that the cords are tightly twisted together. It’s important to keep the colors of the wires separate and not confuse them, as this can cause difficulties when connecting the parts of the fan later on.
3. When twisting the wires, leave about 1 cm of length. If needed, clean and insulate any exposed wires for added safety.

The final arrangement plan for the fan parts

A hazardous situation is created when the "minus" comes into contact with the "plus" in the electrical circuit. It is important to ensure that the black and red wires do not touch during the connection process. If they do, not only the USB cable can get damaged, but also the components of the computer system.

One way to protect a computer from such incidents is to have built-in protection against voltage fluctuations. However, dealing with sockets is much more complex. When there are overvoltages, the socket can short-circuit and disrupt the entire wiring. Therefore, it is crucial to insulate the exposed parts of the wires to prevent any difficulties or unexpected situations.

1. When the device falls, it can rebound directly at the face. However, deep cuts are unlikely to occur from such an occurrence.
2. If the device happens to fall onto a level surface, the blades will simply shatter. The broken fragments will scatter in various directions, and a hazardous fragment might even bounce and hit the eye.
3. There are other potentially dangerous situations to be aware of.

From a disk

You cannot transform a disk into a cone. However, this material can be useful for making blades. Let’s take a closer look at the step-by-step instructions for creating the individual components:

1. Since the fan with disk blades does not use a standard cooler, you will need to purchase or find a specialized motor. This motor will set the design in motion. Alternatively, you can repurpose a motor from a system cooler used for cooling. It is important to select a motor that is compatible with a particular component – either protruding iron or plastic rods. However, using a disk will result in a propeller that is much more efficient and durable. Old VCR and player parts can be used as motors. These materials are ideal since they involve unwinding disks and cassettes. It is not recommended to use a motor from a washing machine or a broken fan, as these devices rotate the propeller at a high speed. If you use poor-quality tools during the assembly process, the design will be weak. Therefore, it is essential to first choose a motor with a suitable rotation speed. If the motor rotates too quickly, there is a risk of the blade base splitting and scattering throughout the room. The running motor is wired in the same manner as previously explained.

What materials are definitely not suitable

The fan blades and cone should not be made from the following materials:

1. Paper is not suitable for constructing a fan at home due to its impractical properties. It easily gets soaked when it comes into contact with water drops, and even high humidity in the room can render the paper device inoperable. However, some people use paper to make decorative fans that work when the wind blows. If you want a more durable paper device, you can use cardboard from boxes.
