The Anenometer

This project is based on making an anemometer. An anemometer measures wind speed. This is an instructable that has easy steps to create a working model of the anemometer using house supplies.

What you need:

2 straws

5 paper cups

1 pencil with an eraser on the end

1 pushpin

1 holepuncher (But if you don't have one you can use a pencil)

Making a base for an anemometer before attaching other components turns out to be an important step for the present product. To start making a base, take one of the cups and punch four holes into it using the hole puncher. There should be two pairs of parralel holes. One pair should be a little higher or lower than the other pair.

Thread the straws through the holes. It should be taken out its opposite hole. Make sure you have an x in the middle of the cup. One of the straws should be overlapping the other.

To make a proper base for your anemometer, you will need to make use of the leftover cups.

Poke two holes on each cup. Make sure the holes are punched in uniformity. The holes must be the same distance apart and must stay in the same level to make sure the anemometer works.

The holes shouldn't be punched in the same manner used for the parallel sets of holes. These holes should be next to each other and not opposite. They should be designed in a flexible position for threading straws.

(Use the image as an example).

Now use one end of a straw to make a support through the holes. It should be threaded through the first hole and come out the other. All the cups should be sewn through one end of the straw.

Make sure that all the cups are facing the same way when you insert them to the main cup.

Now that you have a base, you can attach it to a pole that holds it up.

To make a pole, use a pencil and create a hole in bottom of the main cup. (The main cup is the one that have the x cutting through its middle).

After poking a hole, insert the rubber end of the pencil through the cup so that it is directly below the two overlapping straws. This is going to be your pole that holds the anemometer.

Finally, to finish making a working model of the anemometer, you will need to pin the main components together. (Or else all the unattached materials will fly away).

Use a pushpin to slightly insert it through the two straws onto the rubbery surface of the eraser. It should be held together safe, steady.

Push the pin through the eraser and double check that it doesn't fall off. If it isn't done properly, it might unpin while spinning.

And talking about spinning, your anemometer is done. You can hold it outside and check the normal windspeed or use a fan or your blowing skills to make the anemometer work.
