For a single production of small printed circuit boards, it is convenient to use a frame that can be cut and glued from thick cardboard. The thickness of the frame should be 1...1,5 mm greater than the thickness of the board blank.

The workpiece is placed in the window of the frame lying on the table, and future conductors are painted along the ruler with paint. The frame allows you to apply new lines, without waiting for the drying of the newly drawn ones. It is advisable to fix the workpiece in the frame in one way or another.

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.

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. ... >>

car without a person 27.09.2007

Engineers from the United States are creating a car that can travel 60 miles without human assistance in six hours, traveling along the roads of California.

“Two years ago, we tested a prototype of such a robot car in the Mojave Desert. Then our team showed 8th and 9th results, thanks to which we received financial support from the Department of Defense, Ford and Caterpillar companies. Of course, to travel It’s much more difficult for a robot to drive on the roads of California than in the desert, but we are well prepared,” says one of the participants in the work, graduate student of the University of Virginia Patrick Courier.

The robot, converted from a donated Ford Escape car, was named "One". It was equipped with a powerful on-board computer, a GPS receiver, laser scanners and video cameras. Sophisticated software allows you to simulate human behavior and recognize the maneuvers of vehicles in front.

As a result, the robot is able to drive along a marked freeway, change lanes, go around a stopped car, cross intersections and park. And he does all this without going beyond the rules of the road.

Three laser scanners 25 times in two seconds inspect the surrounding space and measure the speed of approaching "Odin" to a particular object on the road. Four more scanners are installed on the roof. Two of them look for potholes on the road, and two more follow objects that, when maneuvering, fall into the blind zone of the three main scanners.

It is assumed that such robots will carry out tasks for the delivery of goods to the battlefield along a given route during the conduct of hostilities by the US Army.
