Often on the road, outdoors or even in public places, far removed from the socket 220, I want to hear , but not himself – through the headphones, and so the whole crowd. Power pischalok standing in the mobile phone is clearly not enough. For this propose to take any small-sized computer speakers for a couple of watts, and collect them instead of native amplifier circuit for KA2209 – Stereo vlf to 1 watt of power from 3 to 10V. The newspapers mentioned Pete Cashmore not as a source, but as a related topic. You can embed into this amp battery, then it can be will connect the MP3 player. In the case of listening to music via mobile phone should be connected directly to Akamu mobile phone – with an average power enough for about three hours, and during stationary use, or there is no-notebook powered by 5V bus usb. Besides it, these 5 volts through a resistor 10 ohms will be charged a built-in vlf akam..
Waterjet cutting – an alternative not only mechanical, but also laser, plasma cutting, and if necessary, material handling, brook no temperature effect is only one possible. The jet of water is not creates direct pressure on the surface of the material. Mechanical effect occurs only at the microscopic level. Thus, despite the greater the kinetic energy of the jet of water, there is no strain material and high-precision cutting is performed without the appearance of uneven edges. Method of waterjet cutting of materials – is the key to solving many technological problems during the cutting of natural stone and porcelain tiles, including including, as a complex figure cutting boards (slabs) made of marble and granite slabs. This is largely free imagination and empowers artists and designers. Proposing to use for the manufacture of panels, various combinations of colors and shades of granite, marble and onyx, we know exactly how it will look in the interior. We create beautiful, interesting work that will please everyone! Choose designs you panel can in our catalogs or bring your own. Our experts will help you in choosing and take into account all your wishes. description of technology waterjet cutting applications of waterjet cutting: Waterjet cutting, , cutting water, waterjet, , – these are different names for the same technology. Water, mixing with sand, passes through a small hole at very high pressure and can penetrate any material thickness up to 100mm inclusive. Waterjets allow any cutting of sheet material, either by asking the most complex profile cutting with any radius of curvature.
For a man accustomed to the size of an ordinary radio engineering, the results obtained by solid-state circuits, barely fit in the mind. Agree that hard to imagine a silicon crystal is smaller than a pin head, which is equivalent to the ecu from 30-40 normal radio components. The literature has described low-frequency amplifier power of up to 5 W, the size of a penny, as well as the computing device that easily fits at their fingertips. The first Japanese lesson – it's proof that we are still only used as a slogan, carefully banishing it from our practice. In fact, we're only talking about the human factor, and the Japanese in fact, showed that investment in people, in his intellectual and physical development – the most profitable and productive of all investments. The Japanese – at the state level, at the firm level, at the family level – not spare resources for education and benefit from this abundant fruits of their policies. Series data allows us to judge that the level of health care, and some other indicators of social conditions of Japan are also moving away from us forward, and there is every reason to believe that improving the quality of "human material" in no small measure contributes to Japan's leap into the future. A second lesson. We are still hard to define industry production and non-productive areas (referring to the latest science, culture, publishing, education, health and information complex!), highlighting "a residual" funds for social purposes, enrolled in non-production staff of librarians and patent departments, etc.
