Today, many homes have a barometer. This device in some cases is simply irreplaceable. A fishing enthusiast, this simple device allows not only to determine the weather, but also whether there will be a bite. Alas, it is not always possible to purchase a device. But you can make a barometer with your own hands from improvised materials. In fact, this is nothing complicated. It is much more difficult to make an electronic barometer with your own hands. In this case, certain skills and the presence of certain tools are required.
How to make a barometer with your own hands
Several methods for manufacturing such devices are known. Each of the methods of manufacturing the device has not only advantages, but also some disadvantages. This method is considered the simplest. However, not always at hand you can find everything that is required. To make a barometer you will need:
- Glass transparent bottle.
- Glass tube.
- Bung.
- Water.
How to make
To make a barometer with your own hands, you need to prepare all the necessary details in advance. First you need to 1/3 fill the bottle with water. It is best to take distilled. Plain water will bloom a year later. If desired, the liquid can be tinted a little.
After that, it is worth making a hole in the cork and insert a glass tube into it. The joint must be smeared with plasticine. This will seal the hole tightly. The bottle should be corked. As you can see, everyone can assemble a barometer with their own hands.
How the device works
Of course, in order to understand the performance of such a device, it is necessary to know its operating principle. Here, too, everything is extremely simple. When changes in atmospheric pressure occur, the water level in the tube begins to fluctuate. Of course, this is not enough. You need to know when the weather will be clear and when it will be rainy. So, if air bubbles come out of the tube, then the pressure is quite high. This indicates that the weather will be clear soon. It is at such a time that active biting is observed. If water gradually flows out through the tube, then this indicates a low pressure. Accordingly, the weather will be rainy. You can not go fishing, as there will be no bite.
The device from the old paws
Do-it-yourself barometer for fishing can be made from a burnt out bulb. For manufacturing you will need:
- Burnt out light bulb.
- Screwdriver.
- Machine or sunflower oil.
- Medium sandpaper.
- Copper wire.
- Vise.
- Water.
- Ink.
Make a hole
To make a barometer with your own hands from a light bulb, you need to make a hole in it. You need to work very carefully, as the bottle can crack or break at any minute. The hole must be made in the place where the base with the threaded part begins.
There is a fairly simple way. To begin with, make a mark where the hole will be made. Here you should drip a little sunflower or engine oil. From a medium-grained sandpaper you need to remove a little abrasive powder. The resulting material must be added to an oil drop. The result should be a viscous mass.
Insert a piece of copper wire into the chuck of a screwdriver or drill . Its diameter should correspond to the size of the future hole. The base of the paw should be clamped in a vice, and the flask should be wrapped in a rag or towel. You need to drill very carefully, with a minimum of effort.
What to do next
The capacity for the barometer is ready. Now you need to fill it with water. For this, it is better to use distilled. The flask must be filled halfway with water. After this, the liquid must be tinted. To do this, drip a few drops of ink into the water. If they are not in the household, then you can put a piece of lead in the liquid, preferably from a chemical pencil. After this, the resulting composition must be mixed. DIY barometer made of a blown out bulb. It will be possible to hang the device between the window frames. It is best to place a barometer on the north side. Here the sun will not fall on the device. If the windows are located on the south side, then the barometer should be placed at the top of the window. Use such devices only in the warm season, when the temperature is above zero.
How does a light barometer work?
A few hours after the installation of the barometer, it will already be possible to take readings. Of course, you should know how such a device works. If the inner walls of the flask are covered in chalk with drops of condensed water, then tomorrow it will be cloudy. However, there will be no precipitation. If the droplets are of medium size and there are dry vertical stripes between them, then tomorrow cloudy will be observed. That, of course, is not all. If large drops partially cover the flask - there will be short-term precipitation, large drops and flow down - there will be a thunderstorm.
Using such a device, dry weather can also be predicted. If the walls of the flask are dry and even without droplets and fog, then tomorrow it will be clear. If condensation has formed on the north side of the container, then tomorrow, approximately in the afternoon, rain will pass.
