You will need:
Tools: pliers, sandpaper, scissors, digital voltmeter.
Materials: copper wire (size 28 100 m), corrugated cardboard, electrical tape.
1. Make a wrap template by folding a small piece of corrugated cardboard 3 times. The template should be 3 cm wide and approximately 20 cm long.
2. For the next steps, cut 8 pieces of electrical tape 4 cm long.
3. Wind the wire around the template as shown. Make 4 windings. Each consisting of 200 turns of wire, leave a wide gap between the windings, also leave about 40 cm of wire before the first winding and after the last. All this will take about 20 m of wire.
4. Carefully remove the first winding from the template, secure it firmly with two of the eight pieces of electrical tape.
5. Remove the next winding from the template and secure with tape on both sides. Repeat the same with the two remaining windings.
6. Gently sand or scrape off 15 mm of enamelled insulation from the free ends of the wire.
7. Check the windings to make sure that electricity can pass through them all: install a voltmeter (200 ohm limit) and connect the test leads to the free ends of the windings.
8. This is what the finished windings should look like.

Alcohol content of warm beer
07.05.2024
Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>
Major risk factor for gambling addiction
07.05.2024
Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>
Traffic noise delays the growth of chicks
06.05.2024
The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>
| Random news from the Archive Keyboard recognizes gestures
08.05.2014
Microsoft specialists have created a prototype keyboard that can recognize basic hand gestures. According to the developers, the device will be able to simplify and diversify the methods of entering information. The development was presented in Toronto at the Computer Human Interaction conference.
The prototype keyboard contains 64 sensors, which are located next to the keys. They can recognize the movements and manipulations of the hands over the keyboard. For example, if you swipe your hand from left to right, this gesture will bring up the side menu in Windows 8.
According to Stuart Taylor, a spokesman for Microsoft, the main task for the owner of the keyboard is to keep their hands either on it or very close to it when using not only keys, but also input gestures.
Part of the gestures allows you to replace existing keyboard shortcuts - for example, Alt + Tab to switch between windows. "For more complex keyboard shortcuts, gesture substitution seems easier to users," notes Taylor.
The Windows 8 operating system, introduced in 2012, and its updated version, Windows 8.1, were designed specifically for use on touchscreen devices. Therefore, following the release of the platform, numerous transformer devices became available on the market, capable of working with both a touch screen and a keypad.
At the same time, users of computers with traditional input methods - mouse and keyboard - found the novelty not very convenient. For this reason, Windows 8.1 Update 1, introduced by Microsoft this month, has addressed the needs of traditional users. Now the platform automatically detects which device is being used: for a PC, the OS is loaded with the usual "desktop", and for a tablet, a "tiled" interface is loaded.
By combining traditional keypad input with gesture recognition, the user can more easily adapt to new touch screen devices and speed up their work on a conventional PC. At the same time, as Taylor notes, the new keyboard is not capable of replacing the touchpad or computer mouse.
It took about a year and a half to develop the project at Microsoft Research. But the keyboard so far remains only a prototype, and nothing has been announced about plans to bring it to the commercial market.
There is also information about the parallel development of technology for entering information using a combination of traditional mouse and keyboard with gestures in another Microsoft Research lab. At the same time, the Kinect sensor is involved in the development.
