Cut out a circle from thick paper or thin tin. Mark lines on it. Make cutouts along the solid lines, bend the resulting blades along the dotted lines so that they are at an angle with respect to the wind blowing on them. Glue a circle of plywood in the center of the blades. Make a hole in the blade and circle for the axis. The axis will be a thick wire, bent as shown in the figure. The axis must pass through a curved (U-shaped) rack made of thick tin. Make a hole in the rack for the axle.

At the straight end of the axle, reinforce the blades. Mount the rack on a round or square plywood base, which in turn is mounted on a high rack of any kind. Make a rectangular hole in the base, under the curved end of the axle. Attach a strong straight wire to the end of the axis - a rod. With a circular rotation of the blades and the axis, this wire will move in a straight line up and down. Circular motion is converted to a straight line. Get the simplest crank mechanism.

Now you can make a model of a wind turbine adapted for a water pump or saw. So, for example, by making a round pump piston at the end of the rod (for example, from a cork), and under it a pump tube (from cardboard or an old thermometer case), gluing it to the lower base, you will get a model of an engine for pumping water.

It is easy, having made a model of a saw, to demonstrate a file.

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. ... >>

Ultra-fast FRAME camera 02.05.2017

Researchers at Lund University (Sweden) have created an ultra-fast camera capable of capturing 5 trillion frames per second. The shooting speed of traditional cameras does not exceed 100 frames per second.

With the new high-speed camera, researchers will be able to capture transient processes that would otherwise be impossible to capture in photographs or video.

"Now we can capture fast-moving processes such as explosions, plasma flashes, turbulent combustion, as well as capture animal brain activity and chemical reactions," Elias Kristensson, one of the creators of the camera, said in a press release. study of the combustion process.

With this camera, called FRAME (Frequency Recognition Algorithm for Multiple Exposures), Christensson and his research partner Andreas Ehn plan to capture combustion at the molecular level.

The FRAME camera works differently than conventional models. Most high-speed cameras capture images sequentially, one after the other. FRAME uses a computer algorithm to capture multiple encoded images in one, which are then sorted into a video sequence. The object is exposed to laser pulses, each of which is assigned a unique code. The reflected pulses merge into one photograph. These images are then separated using an encryption key.
