Bipolar power supply with conventional transformer winding, 220/15 volts 3 amps

Section Power supplies. The proposed circuit contains a small number of parts, but despite this, it provides fairly high performance. And the simplicity and uncriticality of the parts used makes its repetition accessible even for inexperienced radio amateurs. The schematic diagram of the power supply is shown in Fig. 8.6. It is based on the integrated stabilizer KR142EN5A, which made it possible to achieve high parameters of the entire device ... >>

The simplest signal generator on a single zener diode

Section Measuring technology. The device can be used as a simple signal generator for setting up various amplifying and receiving radio equipment. The signal generator is assembled on a D810 zener diode (D808 or D814A-D814G are also suitable). The circuit diagram of the device is shown in Fig. 1 ... >>

Non-programmable thermostats

Section Electrician's Handbook. In the simplest cable heating systems, non-programmable thermostats are most often used. With a decrease in the temperature of the floor or air relative to the set one by 0,1-0,2 ° C (depending on the model), it switches the system, with an increase in temperature by the same amount it turns off ... >>

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 ... >>

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. ... >>

Self-guided goggles 25.01.2003

Oxford professor D. Silver invented self-guided glasses that are suitable for all people without exception, suffering from poor eyesight.

In order to "adjust" the glasses to a specific person, you need to press two small buttons on the temples, after which the degree of curvature of the lenses will change. According to the professor, his invention will help billions of people who cannot go to an ophthalmologist, primarily in third world countries. For example, in the African state of Ghana, there are only 20 oculists per 50 million inhabitants.

The company founded by the professor has already arranged deliveries of self-focusing glasses to Africa at a price of $9.
