Travel refrigerator. Tips for the home master

Builder, home master

Going out of town in the summer to the bosom of nature, we grab something to eat and a thermos of hot tea with us. It would be possible to take something more substantial, but how to keep everything without a refrigerator? Why don't we make it? Yes, so that even ice cream does not melt in it on the hottest day.

Having used factory papier-mâché egg trays (plastic ones are not suitable), newspapers, magazines, wrapping paper, wallpaper paste and foam rubber strips, it is quite possible to make a thermal container with a useful volume of 3 liters in 4-17 evenings. In shape, it is a cube with an outer face of 360 and an inner face of 260 mm. Pre-chilled food in our mini fridge will stay at the same temperature for up to 20 hours. Of course, it should be remembered that the fuller the container is filled, the longer it retains the cold. And if there is not much to eat (for example, ice cream), pre-cool the container with an ice pack and place plastic bottles with frozen water in it. Before freezing, add table salt to the water. 120 g (4 tablespoons without top) per 1 liter of water will provide a temperature of 8,6 degrees C, and 6 spoons - 12 ... 13 degrees C.

But enough abstract talk. Let's get down to business. Paste 4 pallets on both sides with paper so that it protrudes 50 - 100 mm beyond the edges.

In this case, it is necessary to apply glue not only on paper, but also on the tops of the "pyramids" of the pallet. Before drying, lay plywood on the surface and press down with a weight.

Fold the pallets into a square and glue the protruding inner sheets of paper with an overlap, cutting them at the corners. When everything is dry, fold a square pipe from pallets, picking them up so that the extreme "pyramids" enter into the recesses of the neighboring ones. On the side of the lid between the paper and the tray, carefully glue the pieces of foam rubber and foam plastic so as to seal the cavities.

Lay the top of the container with dense rolls of newspaper and glue the sheets with an overlap. It is especially important to glue the voids, as well as the joints, so that there are no gaps. Paper rollers can be glued along the edges of the container.

Glue or sew a strip of foam rubber or cloth 50 - 60 mm wide along the edge from the inside of the container or sew it with threads to the body. Fill the voids between the foam rubber and the body with any porous material, previously lubricated with glue.

On a strip of cardboard 150 mm wide, glue or sew a tape of foam rubber or cloth of the same width as on the body and put it in a container. After smearing the joints of cardboard and foam rubber with overlapping glue, press them to the body using spacers and strips of plywood. Sew the cloth strip end-to-end without a gap. When the glue dries, remove the spacers and, with a little effort, insert the cardboard frame into the pallet, trimming its edges if necessary. Glue the rollers from the newspaper and paste over the outside and inside with paper, tucking the edges of the frame onto the lid.

Wait for the glue to dry and push the cover out of the case, after marking its position. Sew it in the corners with a large needle with a thick thread or a regular one folded several times and make a loop on the outside. They will be needed to remove the cover. Glue squares of thick cardboard under the thread so that it does not cut the cardboard when opening. Glue the edges of the foam at the cover on one side inward, and at the body - outward for ease of installation.

Place the pallet on the bottom of the container and overlap with paper, gluing the cracks. Glue the paper rollers into the voids and overlap with the outer sheets of paper.

Outside, it would be nice to paste over the container with sheets of thick paper, for example, from magazines. By choosing the appropriate illustrations, you can achieve a kind of artistic design. On the body and cover, do not forget to make marks so as not to look for their relative positions every time.

Lay plywood on the bottom of the container, say, from a parcel box. Through the bottom, pass and glue a twill or tape for handles sewn from a dense fabric.

The refrigerator is ready. You can go hiking.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Samsung has released a mobile phone with a hard drive 23.12.2005

Samsung Electronics is launching its new SPH-V7900 mobile phone, which is notable for having a hard drive inside.

Moreover, this is the second model of a mobile phone from Samsung equipped with a hard drive. The previous phone of this type - SPH-V5400 - was released in December 2004. Its hard drive capacity was 1,5 GB, and the new SPH-V7900 has a 3 GB hard drive (for comparison, most modern cell phones have 100 MB internal memory ).

Of course, any data can be written to 3 GB, but if these are audio, photo or video files, then they can be played directly on the SPH-V7900 phone (MPEG-4 / H.264 video files and MPEG-4 audio files are supported AAC, AAC+ and MP3). The available 2 GB is enough for 3-700 hours of video or XNUMX songs.

The phone also has a function of converting music into visual images. The main TFT LCD screen of the phone has a resolution of QVGA (240x320 pixels) and support for 262K colors, the second small screen on the outer cover has a resolution of 96x96 pixels and support for 65K colors.

In addition, the phone has a built-in 2-megapixel camera with 2x optical zoom and a connector for displaying recorded images on a TV. The dimensions of the mobile phone case are 103x52x27,6 mm, weight - 165 g. The SPH-V7900 phone, like its predecessor SPH-V5400, will work in CDMA networks, so for now it will be sold only in South Korea, where its price will be about 700 dollars.

True, Samsung is preparing a version of this phone for GSM networks. This model is called SGH-I300, it is also equipped with a 3 GB hard drive and runs on Windows Mobile.
