THERE, ZENICA EYE. Our vision — natural stereophotography: the image of the same object on the retina varies, as each “eye” sees the object from a different angle. And only in the brain the signals from the retina from these different images are processed into one three dimensional picture.BOARD ROOM “WEEDING”
It is now customary to control weeds on the beds without chemicals. Weed or often just cover the beds by the opaque material beneath the weeds do not develop, and the seedlings planted directly in the Windows. When the plants in the Windows grows up, the black film is removed and soil mulching. And the Read more…
Using copy booster of the spaceship “Soyuz” in the class of models K-2 has, along with the advantages and disadvantages. In the manufacture of models, it is difficult to meet the launch weight of 120 g. But the complexity of the design allows (high quality models) to high poster ocenku. And we decided to build the engine in the junction of the two conical surfaces of the Central unit. Thus it was possible to refuse to load the nose of the model. The inner surface of the Central unit for protection against burn-out during operation of the engine covered office silicate glue.
The ancient Roman principle of “divide and conquer” is acceptable when… the diagnosis of PC monitor. Especially when you want to find out: is good program for display or handling his job as “electronics”? To the same conclusion when we consider the interaction of the monitor with the system unit of a PC, even if the sight is not complete, but simplified scheme.
Under the heading “advice to the Modeler” magazine “modelist-Konstruktor” No. 11 ’01 published material on how to adapt the radios from cheap toy cars of Chinese production to the remote control equipment, which is lacking in the circles of children’s technical creativity. Penetrating the essence of the proposed technical solutions, I came to the conclusion that the chip KY011 encoder base of the transmitter with a more efficient application allows you to enter two more commands through the use of the 1st and 6th “back-up” pulses.
Often the users PC, with a passion for technical creativity, we have to make copies of drawings and face several specific problems. The paper, which made the original, sometimes it’s yellowed, stained, stains. Or bad the scanner reads the image.
I want to share one small advice. I have an old, since Soviet times, wall clock Mayak. In General, a good watch and was exactly, and a good design, and well preserved externally. But one day they suddenly started to lag, and then stood up. First, changed the batteries, cleaned contacts — nothing helped. After an unsuccessful repair, I was told that they have long no parts and, in General, the road them to the dump.
If you find that the remote control system (CDS) import the TV starts to fail, the first thing I usually replace a power supply in the remote. However, it is unlikely that the performance of the system was then restored fully and permanently. Often TVs continue to “act up”: require precise aiming of the remote, not controlled from great distances, do not work with the first button push…
Replacement flyback transformer in TV monitor МС6105 with CRT 31ЛК is, of course, not a major overhaul. Moreover, if the old monitor staff “strojnik” cope with the work, and to change this (very expensive, cranky and hygroscopic) node to the new is hardly appropriate.
One way to reduce interference in digital circuits, as is well known, is to install the ceramic capacitors in parallel with the power rails. The closer to the contacts of the chip capacitor is, the more effective his work is.
