What is auditory training? Is the ability to replace eight hours of sleep sorokapyatiletnyaya rest. This exclusive attention, phenomenal memory, the ability to “turn off” the pain, stop bleeding, keep warm in the fierce cold. But to master the skills of autogenic training only under the guidance of knowledgeable teachers, working hard for many months and even years. Step by step develops the subtle introspection, a vivid imagination and an iron self-control, the student seizes the opportunities for active relaxation and concentration, learn how to use the formulas of self-hypnosis and consciously control dreams.

My invention is very simple, but quite important as regards health. The practical need for it — there. It is known that in the sinus, the number of colds and other diseases requires the heating of the nose and maxillary sinuses. Better suited for this UHF-therapy. However, at first, excessive exposure to currents of UHF may prove harmful to the body, and secondly, this equipment is complicated and cumbersome road. Therefore, this method of treatment, despite its advantages (depth of penetration, and disinfecting effect), not very applicable.
Kit electronic Christmas decorations from four independent devices developed and produced by the student of 9th class member directorship radio children’s Palace of creativity from the city of Saransk Alexei Pichushkin. On the urban exhibition of technical creativity in 2004 with these decorations won first place.
In many technical constructions, devices, in laboratory and bench equipment, automobiles used a DC electrical supply voltage of 12 V overload protection, which can lead to spontaneous combustion, is a very important task.
On the radar heard many. The transmitter sends powerful electromagnetic wave in the direction of a moving object (airplane, ship). Upon reaching it, the wave is reflected and received by receiver. Time delay of the sent signal to determine the distance to a plane or a ship and its speed.
Every radio Amateur knows how it is sometimes difficult to find in electronic equipment, faulty transistor, especially when there is no instrumentation. From the diagram it is necessary to use almost all transistors until you find the “culprit” of the failure. I tried to test the transistor directly into the circuit, not Vipava it.
In technical literature there are many publications on improvised electronic code locks — variety of complexity and management that is performed on chips as small and medium scale integration and microcontrollers. Unfortunately, most of the first it is impossible to quickly change the code, since it is necessary to solder a jumper, or make other changes to the installation. In others, although provides for reprogramming of the microcontroller, but a very limited number of times. Furthermore, these modifiable combination locks consume in standby current of approximately 1 mA, which makes pay attention to the selection of source of energy when you use the above devices in both local (field) conditions where it is impossible to use network adapters.
Most radio Amateurs, unfortunately, do not publish their devices. Although sometimes their design is novelty, which still has not invented and did not. In the magazine “Radio” in may 2013, includes an article about the timer on the IC CD4060B, who ran a heated electric blankets.
If you need to smoothly adjust the light in the floor lamp, chandelier or table lamp, usually used autotransformer. However, this controller is bulky and low economical to exploit at.
