Three-piece ZYGI BEAM

HF Antenna Section. Radio amateur G3PTN developed the design of a two-element antenna, which he called Zygl-beam. It is an active powered antenna. Both elements are made in the form of open rectangles located in the same plane. As a result of experiments to increase the efficiency of the antenna, the author developed its three-element version, the circuit of which (for the 14 MHz range) is shown in the figure. The three-element Zygi-beam, according to the author, has a higher forward-backward radiation ratio (up to 20 dB) and a higher gain (up to 65 dB). The input impedance of the active vibrator is XNUMX Ohms ... >>

Pocket radio Moscow

Section Radio reception. The radio receiver operates in the range of 300-1800 m. For the magnetic antenna, an F-600 ferrite rod with a length of 80 mm and a diameter of 8 mm is used, on which a thin paper frame is placed. On the frame, coils L1 and L2 are wound in bulk, containing 130 turns of PELSHO-0,12 wire. The total winding length of the coils is 25 mm. Communication coil L3 has 3-5 turns of the same wire wound on top of coils L1 and L2. Transformer Tp1 and RF choke are wound on NTs-2000 ferrite rings with an outer diameter of 7 mm. Windings L4, L5 and L6 contain, respectively, 100, 10 and 200 turns of PELSHO-0,12 wire ... >>

DRV-0,1 electric motor in a tape recorder

Section Reference materials. Tape motors such as DKS-8, 4DKS-8, DKS-16, ZDPRS known to radio amateurs are expensive and rarely available for sale. Making a good engine on your own is quite difficult. The author of the article in several designs of tape recorders used the DRV-0,1 electric motor used in the Efir-M radiol (see Fig. 1). This relatively inexpensive motor is powered by a battery, batteries or a rectifier ... >>

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. ... >>

Canon Zoemini Smartphone Micro Printer 12.08.2018

Canon has introduced a new device called Zoemini, which is the brand's smallest and lightest photo printer. The device has dimensions of 118x82x19 mm and weighs 160 g. The printer is designed to print pictures from smartphones and tablets. Zoemini works with gadgets running Android and iOS operating systems. The proprietary application provides the ability to add filters and frames.

Printing requires special paper with ZINK technology, the crystalline substance of which is colored when heated. The result is photographs 76x50 mm in size. Communication with the smartphone is carried out via Bluetooth 4.0. The built-in 500 mAh battery allows you to print up to 20 photos.

The price of the device, including 10 sheets of photo paper, is 140 euros.
