At home, we often have to work with electric tools and devices (electric drill, electric scissors, electric furnace, etc.) at a considerable distance from the outlet. And if the extension cord is long (more than 25 m), it becomes difficult to unwind it, wind it up and store it.

Therefore, we decided to make a portable extension cord (see fig.). It consists of a base, a stand and a reel with a wire mounted on an axis. A plug connector is connected to one of its ends, and a plug to the other. The reel is mounted on the axis with the help of shaped washers and is locked with a wing nut.

The rack consists of a 1/2-3/4 "pipe curved in the form of a bracket and two corners welded to it. An axle is welded to the upper one, on which a reel with a wire is installed, and with the help of the lower rack it is fastened with two screws and nuts M6 to the base.

Portable extension cord (click to enlarge): 1 - plug, 2 - bobbin, 3 - base, 4 - plug, 5 - handle, 6 - wing nut, 7 - shaped washer, 8 - wire, 9 - stand, 10 - screw and nut M6, 11 - axis

Work with a portable extension cord as follows. Unlock the wing nut by 1/2-3/4 turn and wind the wire from the bobbin to the desired length: the plug is connected to the mains socket, and the current consumer is connected to the plug mounted on the bobbin. At the end of work, the wire is wound up by rotating the bobbin with a handle and then locking it with a wing nut.

More than 40 m of wire can be wound on the carrying extension, while it does not take up much space during storage.

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 ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Smart home from IKEA 25.08.2019

IKEA said it is betting heavily on smart home technology as a new source of revenue. To do this, the company intends to invest in a new business unit "IKEA Home Smart", which will develop smart devices.

Company representatives say that in order to speed up the development process, it was decided to create a new division and invest heavily in its development. IKEA's smart home ambitions began as early as 2015 with the introduction of tables and lamps that, thanks to integrated wireless charging technology, could be used to recharge compatible devices. In 2017, the company began offering smart lighting systems to customers, and from September 1 of this year, smart blinds will go on sale in the United States. It is likely that IKEA will soon start producing more devices designed to create a "smart home".

According to the forecasts of the analytical company IDC, global sales of devices in this category in 2019 will amount to about 830 million units, in 2023 this figure will increase to 1,6 billion units. Therefore, it is not surprising that IKEA plans to expand beyond the production of ordinary home furniture.

The company believes that the joint work of IKEA Home Smart with other divisions will contribute to the digital transformation of the enterprise. The existing production will be improved and transformed, due to which new intellectual products will appear on the market.
