CELL GUARD

CELL GUARDToday, phone operators, representing a population of mobile communication services, even in remote regions have made their rates available to most consumers. Constantly updated market of mobile telephones (AIT) allowed to acquire outdated but workable model for a symbolic price. Given this, anyone who is familiar with the basics of electrical engineering are given the opportunity to make the mobile phone almost free, automatic Secretary, who will notify the owner about the state of its protected values; whether it be apartment, a country house, safe, car or access to a personal computer. Now cellular telephone connected by the following method with a sensor that will automatically inform the owner about the condition of the protected property, wherever that may be. This is my article.

NOT POUR, AND INCLUDE

NOT TO POUR, BUT TO INCLUDEMy 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.

OTK IN THE SCHEME

OTK IN THE SCHEMAEvery 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.

PROGRAMMABLE CODE

PROGRAMMABLE CODEIn 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.
