Do not rush to throw away the used plastic bottle of a ballpoint (gel) fountain pen - you can make a frame for a HF or VHF contour coil and parts for attaching the frame to the board from it.

Frame - from a ballpoint pen

First, frame 1 (see figure) of the required length is cut from the balloon. Then the plug with the writing unit is finalized: the writing unit (shown by a dashed line) is removed, and the remaining part in the form of a plug 2 is passed through the hole in the board 3 and the frame 1 is put on it. For greater reliability of fastening, the parts are lubricated with glue.

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 ... >>

Panasonic Lumix DMC-FZ70 60x optical zoom camera 05.08.2013

Panasonic has announced the addition of the DMC-FZ70 to its Lumix range of digital cameras. Equipped with a 20mm to 1200mm equivalent focal length lens, this camera's 60x optical zoom is more than double that of its predecessor, the Lumix DMC-FZ60. The optical scheme of the lens includes 14 elements in 12 groups, among them six are aspherical, and three are made of low dispersion glass. As for the maximum aperture of the lens, it varies from F / 2,8 to F / 5,9.

It goes without saying that with this optical zoom, the camera is equipped with an optical stabilization system that also works when shooting video. The Panasonic Lumix DMC-FZ70 uses a 1/2,3-inch CMOS image sensor with a resolution of 16,8 MP and a Venus Engine image processor. The camera allows continuous shooting at 9 frames per second in maximum resolution and Full HD video recording at 30 frames per second.

The novelty supports iA intelligent shooting mode, and also allows you to apply 15 different effects to photographs. It also supports saving pictures in RAW format.

The Panasonic Lumix DMC-FZ70 is equipped with a 3-inch display with a resolution of 460 dots, the amount of integrated flash memory of the product is 000 MB. It is supposed to use SD, SDHC or SDXC cards as the main data storage. The camera is equipped with a USB port and a Mini HDMI video output.

Overall dimensions of new items - 130 x 97 x 118 mm, weight - 606 grams. The battery life of the camera, measured according to the CIPA standard, is 400 shots.

The Panasonic Lumix DMC-FZ70 is priced at $399 in the US.
