DIY windmill for $150



Section Alternative energy sources. Recently, I had the idea to generate my own electricity for the house. It was not a great need, but my interest in this topic increased when I read an article about assembling a windmill with a motor from a treadmill and PVC pipes. Having previously estimated the costs, it turned out to be about $ 150-200 for a windmill that could generate approximately 50-250 watts of electricity (this comes out much cheaper than using solar panels for the same output power). And in this article I will share with you my experience of making a windmill with my own hands. ... >>

Prefix Color sound



Section Beginner radio amateur. Prefix Color sound. One of the popular amateur radio designs is the light-dynamic installation (SDU). It is also called a color-music prefix. When you connect such a set-top box to a sound source, the most bizarre color flashes appear on its screen. ... >>

Automatic light effects on the chip K556RT4



Section Color and Music Settings. This machine is designed for sixteen programs, each of which consists of sixteen combinations. Therefore, it is possible to implement combined lighting effects in one program, for example, running lights forward and backward, running shadow forward and backward, cumulative switching on and off. The best light effect is obtained when the light sources are arranged in the form of a chain or garland. The machine implements automatic selection of programs for switching light sources. The machine has three modes of operation. In the first mode, automatic enumeration of all programs is provided, with each program repeated ten times, after which a transition is made to the next program and, accordingly, to another lighting effect. This mode uses all the features and benefits of this slot machine. ... >>

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 ... >>

Laser device that produces particles with negative mass 13.01.2018

In our physical world, if you push any object, it, according to Newton's Second Law, begins to move away from you. But objects with negative mass will act contrary to this principle, the more you push them, the faster they will move in your direction. All this seems like an impossible thing, nevertheless, such an effect has long been theoretically substantiated and its manifestations were observed in some experiments. And recently, researchers at the University of Rochester completed the development of a device capable of producing particles with negative mass.

In experiments conducted by scientists at the University of Washington last year, a "fluid" consisting of a Bose-Einstein condensate, a cloud of rubidium atoms cooled to an ultra-low temperature by laser light, showed negative mass. In the device created by the Rochester researchers, the negative mass effect is exhibited by quasi-particles produced by fusing photons of laser light with excitons produced in a semiconductor material.

The design of the new device is in many ways similar to that of a conventional laser. Light is directed into the gap between a pair of parallel mirrors. The space enclosed between these two mirrors is called an optical trap, and at the center of this optical trap was placed an atomically thin layer of a semiconductor material, molybdenite, molybdenum disulfide, which interacts with the light trapped inside the optical trap. Excitons produced in a semiconductor combine with photons of light to form quasi-particles called polaritons, which exhibit the negative mass effect.

"By forcing an exciton to give up some of its 'identity' to a photon of light, we get negative-mass polaritons," says Nick Vamivakas, lead researcher. If the "negative" polariton is pulled or pushed, it will begin to move in the opposite direction to that which intuition tells the person."

Scientists from Rochester still continue to work, exploring the physics and behavior of particles with negative mass produced by the device they created. The field of practical application of this achievement has not yet been determined, but scientists are confident that the use of "negative" polaritons will make it possible to create more powerful and efficient lasers.
