I have been subscribed to "Modeler-Constructor" for a long time and find a lot of useful things in it, especially in the "Club of Home Craftsmen" section. On the advice of the magazine, he made a lot of things for the house and garage.

But I don't just use other people's ideas. I design myself. For example, I have a home-made planer with interchangeable pieces of iron, which, it seems to me, could be useful to a home master. The tool is easy to manufacture, and it can perform several operations: planing, chamfering, taking quarters and, importantly, choosing grooves of different widths and at different distances from the edge of the part.

The block of the planer is made of hardwood. It has a notch, a thrust plate seat, a groove for the head of the locking screw, as well as front and rear steps with grooves for the bolts for fastening the limiter bar.

A plywood sidewall 5 mm thick is attached to the block with six screws. Its use drastically simplifies the manufacturing technology of the block - the notch can not be hollowed out with a chisel, but cut out with a hacksaw.

A piece of iron with a cutting edge designed for a particular operation is first connected with an M3 screw to the cubic head of the adjusting screw, then inserted into the entrance (for an additional M4 through screw passing through the block and sidewall) and fastened in the cutout of the thrust plate with a wing nut and a lock nut M4. The adjusting screw sets the thickness of the chip removed in one pass, or the depth of the groove (depending on the shape of the cutting edge).

Universal planer (click to enlarge): 1 - M4 wing nut (3 pcs.), 2 - M4 bolt (3 pcs.), 3 - sidewall fastening screw (6 pcs.), 4 - sidewall, 5 - block, 6 - fixing screw, 7 - adjusting screw, 8 - locknut, 9 - screws for fastening the thrust plate, 10 - thrust plate, 11 - piece of iron (A, B, C - cutting edge options), 12 - limiter bar, 13 - nut M4, 14 - screw M4.

The distance from the edge of the part at which it is necessary to select the groove is determined by the limiter bar: it is fixed with two M4 bolts with wing nuts. And not only the distance, but also the width of the groove, because thanks to the rearrangement of the bar, you can, working with the same piece of iron, get a groove of the required width.

I made the pieces of iron from the blade of a metal saw that has served its time (easel), but you can also make them from a strip of tool steel.

I am satisfied with my planer: the surface quality obtained when processing parts is quite satisfactory.

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.

Replacing silicon to reduce transistor size 06.12.2020

Silicon has been the dominant microchip material for decades, but its dominance may be ending. MIT researchers have found that an indium gallium arsenide alloy could be the basis for making smaller, more energy efficient transistors.

Transistors are the building blocks of computers. They act as switches, either interrupting the electric current, or allowing it to continue, and thereby ensure the operation of computers. However, in order for the growth of computer power not to stop, more compact transistors are needed. Today, semiconductor manufacturing is based on silicon, but there are alternatives. For example, indium gallium arsenide (InGaAs).

This material has excellent electron transport properties. InGaAs transistors can process signals quickly and operate at relatively low voltage, which means they can really improve the performance of computers. But there is one catch, writes MIT News. On a small scale, the famous electron transport of this compound is degraded. This problem has led some researchers to declare InGaAs an unsuitable material for transistor production.

However, the MIT scientists found that indium gallium arsenide's performance problems are due in part to oxide trapping, which makes it harder for electrons to pass through transistors.

After studying their frequency dependence - the speed at which electrical pulses travel through a transistor - they noticed that the performance of InGaAs drops at low frequencies. But at a frequency of 1 GHz or more, the connection works perfectly - no worse than silicon.

Scientists are confident that this problem can be solved or reduced to nothing, and they also hope that their discovery will spur new research on indium gallium arsenide.

Carbon nanotubes could be another alternative to silicon in field-effect transistors, but so far they have been produced in small quantities in laboratories. Specialists from the United States proposed a technology for creating CNFET on an industrial scale.
