One of the main parts of our magic lantern there was a shoebox. You can also make a camera from the same box. True, he will not be able to shoot, but he will "aim" perfectly.

The most expensive part of a camera is the lens, a complex combination of lenses. But we will do without a lens at all. It will be replaced by a small hole drilled in the middle of one of the end walls of the box. The one that indicates the size, style and type of shoes. Cut out the opposite wall. Leave only a narrow edging to stick oiled paper or drawing tracing paper (also oiled) to it. It is better to glue first, and then oil it. After all, glue will not stick to the oil. And it is better to take machine oil.

Put your "camera" on the table and point it with a hole at the window. On oiled paper, you will get a clear upside down image of the window and everything behind it. True, the light in the room "clogs" this image. Therefore, consider it, covered with dark matter.

Camera with a hole

You can also take the "apparatus" outside, but don't forget to take the dark matter with you.

The image is real. If you put a photographic plate instead of oiled paper, you can take pictures. Interestingly, the first camera was very similar to our shoe box! Lens, shutter, viewfinder - all this came later. And at the beginning there was only a box with a hole and with frosted glass for aiming, in the place of which a plate was then put.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Safe nuclear fuel based on thorium 03.10.2020

The Idaho National Laboratory at the US Department of Energy, together with Texas A&M University and Clean Core Thorium Energy, began work on introducing a new type of fuel to nuclear power plants. It was called ANEEL (Advanced Nuclear Energy for Enriched Life) and differs in that it consists almost entirely of safe thorium, not uranium.

The technology is patented, all details are classified, but the Americans promise to establish cooperation with all interested parties.

Since thorium is a weakly radioactive metal, it will not decay on its own, so you need to add some uranium to it to start a chain reaction. But it requires relatively little relative to the total volume of fuel loaded into the reactor - de facto it is thorium that will burn out in it. It has a higher melting point but lower operating temperature than uranium. This means that the fuel can burn longer without the risk of a core meltdown.

According to the developers of ANEEL, the amount of radioactive waste during the transition to it will be reduced by 80%. Yes, it will be necessary to redo the reactor itself and related components, which is what Clean Core Thorium Energy engineers are doing. But such a reactor is easier to manage, safer and more reliable than uranium. The company promises to create the first reactor for ANEEL by 2024.

However, the main feature of the new fuel is not in the technical, but in the economic plane. American power engineers are betting on India, which does not have its own uranium, but almost 300 thousand tons of thorium is concentrated in monazite sands - 32% of the world's reserves.
