On the manufacture of output transformers for lamp UMZCH

Section Audio. An interesting trend is observed: the further we move away from the tube era, the more myths and fog are created around the output transformer of a tube amplifier. And not only in matters of calculation, but also in its manufacture. Manufacturers can be understood, praising their products is the law of advertising, but in many articles by independent authors, the process of winding a transformer looks like a description of a secret rite. Let's see how difficult it is and how much time it takes. The conversation will focus on output transformers for single-ended stages, as well as other transformers where high symmetry of half-windings and strict requirements for operating conditions are not required. It is assumed that you have a sufficient section of the magnetic wire, winding wires and at least a primitive device for winding coils, equipped with a coil counter ... >>

Pulse metal detector, theory

Section Metal detectors. In the types of electronic metal detectors considered earlier, the reflected signal is separated from the emitted signal either geometrically - due to the relative position of the receiving and emitting coils, or using special compensation circuits. Obviously, there may be a temporal way to separate the emitted and reflected signals. This method is widely used, for example, in pulsed echo and radar. When locating, the delay mechanism of the reflected signal is due to the significant propagation time of the signal to the object and back ... >>

Soldering iron tip temperature controller

Section Power regulators, thermometers, heat stabilizers. This regulator differs from similar ones published in that it regulates (reduces) the thermal power of the soldering iron not by changing its supply voltage, but by interrupting the current through the heater for longer or shorter periods of time. Due to the significant thermal inertia of the soldering iron, after some time after changing the average power, it reaches a new stable tip temperature. In addition, the device provides automatic shutdown of the soldering iron if it is on the stand for a long time. The regulator is designed to work with a standard soldering iron. rated for AC power ... >>

The speech of sperm whales is similar to that of humans 18.05.2024

In the world of the ocean, where the mysterious and unknown coexists with the studied, sperm whales, with their huge brains, are of particular interest to science. Researchers, working with a huge array of audio recordings collected during the Dominica Sperm Whale Project (DSWP) - more than 8000 recordings, seek to unravel the secrets of their communication and understand the structure and complexity of the language of these mysterious creatures. By studying in detail the recordings of 60 sperm whales in the eastern Caribbean, scientists have revealed surprising features of their communication, revealing the complexity of their language. "Our observations indicate that these whales have a highly developed combinatorial communication system, including rubato and ornaments, which indicates their ability to quickly adapt and vary during communication. Despite significant differences in evolution, sperm whales have elements in their communication that are characteristic of human communication," says Shane Gero, a biologist at Carleton University and director of the CETI project.

Electron spin for quantum information transfer 18.05.2024

The transfer of quantum information remains one of the key tasks of modern science. Recent advances in the use of electron spin to expand the capabilities of information transfer in quantum systems have become very important. Researchers at Lawrence Berkeley National Laboratory are pushing the frontiers of quantum information science by experimenting with the possibilities of electron spin. Electron spin, a natural quantum bit, is a potentially powerful means for storing and transmitting information in quantum systems. Magnon wave packets, collective excitations of electron spin, have revealed their potential to transmit quantum information over significant distances. The work of Berkeley Lab researchers has revolutionized the way such excitations propagate in antiferromagnets, opening up new prospects for quantum technologies. Using pairs of laser pulses, scientists disrupted antiferromagnetic order in one place and simultaneously studied it in another, creating ... >>

Sound-absorbing silk 17.05.2024

In a world where noise is becoming increasingly intrusive, the emergence of innovative materials that can reduce its impact is of great interest. MIT researchers have unveiled a new sound-absorbing silk fabric that promises to revolutionize quiet spaces. The Massachusetts Institute of Technology (MIT) has made significant breakthroughs in the field of sound absorption. Researchers have developed a special silk fabric that can effectively absorb sound and create cozy, quiet environments. The fabric, thinner than a human hair, contains a unique vibrating fiber that is activated when voltage is applied to it. This feature allows the fabric to be used to suppress sound waves in two different ways. The first method uses fabric vibrations to generate sound waves that cover and cancel out unwanted noise, similar to noise-canceling headphones. This p ... >>

Navigator in the windshield of a car 16.07.2013

Garmin has introduced an in-car system that displays navigation information on the windshield, thereby allowing the driver to keep their eyes on the road.

The system includes a projector, which is placed on the dashboard of the car, and a film or lens - they are attached to the windshield, and information is projected onto them. The transparent screen displays the direction arrows, the distance to the next maneuver, the current speed and the estimated time of arrival. The user is also warned about traffic jams and cameras. The screen brightness is adjusted automatically depending on the lighting conditions.

The information shown on the screen is taken from a smartphone on which one of the Garmin applications - StreetPilot or Navigon is installed. The system connects to a smartphone via Bluetooth.

The system, dubbed the Garmin HUD (for head-up display), will go on sale before the end of the summer and will cost $130.

Some manufacturers, on their own initiative, build similar indicators into their cars. They are, for example, in the BMW M6 and Lexus HS. The advantage of the Garmin system is the ability to fit in any car.
