To cut a large diameter round hole, make a glass disc or a ring, this simple tool will help.

It consists of only three parts. The dimensions of the steel rod Ø 5 mm depend on the size of the cut hole. For small radii, you can use a nail without a hat. A hole Ø 2,4 mm is drilled in its end face and an M3 thread is cut to a depth of 10 mm. The second part - a steel sleeve Ø 10 mm and a height of 5 mm is turned on the machine (it is permissible to use an M6 nut with an inner diameter of about 5 mm). Drill a radial hole in the middle of the side face and cut an M2,5 thread. And finally, the third, smallest part - the central stop - is made from a piece of the M2,5 screw. Sharpen its end and cut two flat flats with a needle file.

To install a conventional glass cutter with carbide rollers on a fixture, you will need to replace the M3 screw with a longer one - so that after assembly it protrudes by 5-7 mm.

Glass cutter-compass
Tool for cutting round holes in glass (click to enlarge): 1 - glass cutter, 2 - M3 screw, 3 - rod Ø 5 mm, 4 - central stop (M2,5 screw), 5 - sleeve (M6 nut), 6 - cardboard, 7 - glass

Having screwed the rod onto the screw of the glass cutter, put a sleeve on it and fix it at the required distance with the M2,5 screw, turning it with pliers by the flats. Then glue a square piece of cardboard to the workpiece, put the tip of the screw on it, and the glass cutter-compass is ready to work.

Blinking of the magician and his audience 19.05.2024

Magic and illusions have always captured the attention of the public, but what happens behind the scenes of the magician and in the brains of his audience? Scientists from the UK decided to solve this mystery by conducting a new study involving ten illusionists of varying experience. Illusionists, some of whom had been practicing magic for more than half a century, others for only six months, were invited to demonstrate the same trick - the popular coin trick. Recordings of their performances during training and on stage showed that each of them began to blink significantly more often at the moment of performing the trick. The study's findings indicate that magicians' blink rate may be related to unconscious aspects of their performance. At the same time, as scientists have found, spectators also begin to blink more often, following the movements of the illusionist. This observation supports the idea that magicians may be catalysts for blinking in audiences. Additional research has shown that magicians blink more often during ... >>

Ultrasonic coffee machine 19.05.2024

Iced coffee has become an integral part of coffee culture in recent years. Therefore, engineers from the University of New South Wales decided to improve its preparation. They have developed an ultrasonic coffee machine that reduces the cold brew time for ground coffee beans from 12-24 hours to significantly less time. Iced coffee, or "Cold brew", is popular due to its smoothness, low acidity and low bitterness. It is prepared by steeping ground coffee in cold water for a long time. Unlike traditional hot brewing, which often imparts bitterness to coffee, cold brewing extracts more delicate and complex flavors from the coffee beans. The innovative system, presented by a team of engineers, introduces ultrasonic technology into the coffee preparation process. The system uses ultrasonic waves to speed up the process of extracting oils, flavor and aroma from ground coffee. This allows you to significantly reduce the time ... >>

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.

High-speed optical communication Li-Fi 15.06.2013

Li-Fi, short for Light Fidelity, is an optical wireless technology developed and presented by Harald Haas at the 2011 TED Talk. The French company Oledcomm announced that the first communication devices of its production, based on Li-Fi technology, will be available on the market next year.

Li-Fi technology works by binary modulating light from a special LED source. Modulation is carried out at a high frequency, and the transceiver itself in appearance is no different from an ordinary LED light bulb for household lighting.

Receiving sensors connected to computers or other digital electronic devices allow you to receive information when they are exposed to direct light from a Li-Fi source. This imposes some restrictions on the use of this technology, but in the end, such optical communication is somewhat safer than traditional Wi-Fi, the signals of which can be intercepted from anywhere within the range of the equipment. In order to intercept information transmitted via Li-Fi, an attacker will need to place his spy equipment literally on your lap, which can lead to serious difficulties for him.

In addition to the above, Li-Fi optical wireless technology can be used without restriction in places where the use of equipment that emits extraneous radio waves that may interfere with the normal operation of critical equipment is prohibited. Such places, of course, include intensive care wards of medical institutions, aircraft cabins and some other places.

At present, the information transfer rate that Li-Fi technology can provide is slightly higher than the speed of traditional Wi-Fi. Oledcomm representatives report that they have managed to obtain a stable information transfer rate of about 3 Gb / s, and a transfer rate of 10 Gb / s will be achieved in the very near future.
