       1. Electric ignition device - In section presents several schemes multispark electric ignition devices in different hardware components for gas stoves, hot water column or boiler operating on gas. The principle of operation, advantages and disadvantages of each design detail on the following pages. Schemes designed to replace regular electric ignition devices. At the end of this section the methods of controlling the flame on the burner gas appliances. The scheme of the device, operating with an ionization electrode, as the most reliable and easy solution..

        2. Wired videosender - section contains multiple concepts, with different elemental base devices to transmit IR commands regular remote control of home electronic equipment from one room to another. The scheme is useful when the apartment has one or more signal sources that are concentrated in one room, such as a VCR, DVD player or receiver of satellite television, which is made from cabling to multiple rooms with television. These signal sources can be controlled from any room (up to 100 m) using regular remote controls.

        3. Chargers for different batteries - section contains a large number of schematic diagrams of different charging devices for automatic disconnection of the battery when charging the DC stable. The scheme uses methods of battery disconnect after a specified time or achievement of specified voltage. The proposed structure designed to charge the car and small nickel - cadmium batteries, a charger with digital display is very easy to use and as a laboratory supply of various electronic devices in their troubleshooting and repair.

        4. Chargers for automobile batteries - section circuit power chargers for currents up to 10A with the stabilization of the current charge, automatic shutdown after the charge cycle, digital display of voltage and current. There are diagrams of laboratory power supply with overload protection and function of the charger. The scheme uses the widespread elements: thyristors, power bipolar and field (MOSFET) transistors. Many structures in the very popular and affordable chip TL494.

        5. Phase AC voltage regulators - under a review of existing methods of phase control AC voltage level, the advantages and disadvantages of simple and complex circuits. We consider the basic electrical circuits of different voltage and current regulators for network loads, which are very good to use for a variety of lighting fixtures, electric heaters, electrical fans, welding machines, electric motors and the collector, etc.

        6. PWM DC regulators - under the schemes of simple pulse - pulsed power supply regulators for DC consumers. Schemes are especially useful to owners of vehicles wishing to make a smooth turn on or off the various lamps, including lamps, fan speed control in the cabin or to make a new scheme for the fan control air conditioner instead of a failed, to use the scheme to regulate the heating of the driver's seat, etc.

        7. Signaling devices for liquid level home automation - the section contains schematic diagrams of a large quantity of liquid level sensors designed for the construction of automatic water supply of the household and remote signaling the presence of water in the storage tank. Contains an analysis of existing methods of control levels, their advantages and disadvantages. Schemes are built on different hardware components and placed on the principle "from simple to complex.

        8. Uninterruptible supply of the household - in the section presents a large number of schematic diagrams electronic automation devices to control water pumps in deep wells or booster pumps gidrofornyh plants. The principles of construction of such devices based on liquid level sensors. All schemes contain different element base for ease of assembly. Most devices contain audible and visual alarm modes of operation and protection against contingencies. The devices are very useful for uninterrupted water supply of residential houses, apartments or suburban housing. All designs can be used to automate the pumping of drainage water from the pits, etc.

        9. Automation in daily life. Various electronic appliances for household use - section contains descriptions of various electronic devices for the home and everyday life, the author developed the site in different years, are devices for collecting bee venom, voltage converters, 12 V DC / 220 = (DC / DC converters) to supply energy-saving lamps or adapter laptop or cell phone in field conditions by the car battery, the device overwrite the copy-protected video formats VHS, electric rods, measuring the thickness of nonmagnetic coatings on steel (for example, the thickness of paint a car), governor of the collector motor AC 220V, various timers and timers, switch the car beeps, the device vibroacoustic treatment of many diseases, the device for electro biologically active points of human, electronic thermometers and thermostats for refrigerators, incubators, air conditioners and other home appliances, digital display of temperature and without circuit protection devices from home appliances high-voltage, simple Audioon-door to give, timebase 50 Hz for modification in order to improve the accuracy of the distributed network of electronic watches that use the network as a source of reference interval circuit probes for continuity of electrical circuits, switches, sound or light signals and car much more.

       10. Electronic Mouse Trap. Traps for small animals - in section discusses the fundamental electrical circuits several electron traps with power from both the network and from the battery or batteries of electrochemical cells. The traps do not harm the animals caught and can be used to capture pets: hamsters, guinea pigs and other small animals or birds, as well as for the capture of unwanted guests - rats and mice. When triggered, the trap includes intermittent audible alarm, informing the owner that it is "caught".

       11. Remote control of a chandelier - the section contains a large number of voltage regulators circuits of varying complexity and varying elemental base for incandescent lamps in a variety of lamps, electric heaters or similar devices is managed using a simple switch or infrared remote control of consumer electronics. In simple variants of the voltage change is made in steps, by briefly disconnecting the switch, but more complicated schemes allow smooth adjustment with the remote control. There are schemes to enable an independent - one off load from two or more different locations.

        12. Alternating voltage stabilizators - when the mains voltage deviation of more than ± 10% from the norm can cause problems in some household appliances: refrigerators, microwave ovens, vacuum cleaners, elektroutyugov, food processors, etc., which are easily solved by applying AC voltage stabilizer . This section contains an overview of the principle of operation of such devices and schematic diagrams of structures developed by the author site.

        13. Welding oscillators. This section contains descriptions of additional devices to the welding machines which allows the AC to use electrodes of direct current. It is not necessary to supplement the unit with rectifier bulky inductor is sufficient to apply a welding oscillator, several schemes which can be viewed in this section. These oscillators are often used in devices argon welding. There is a description of welding semiautomatic producing welding wire special diameter of 1 mm in carbon dioxide environment.

       14. Security alarm. For the protection of vehicles produced dozens of alarm systems, and for the protection of the garage, house, cottages, etc. Such devices have to do everything myself. What methods of control unauthorized entry into a dwelling or garage, modes of transmission alarm via radio or communication line and are covered in this section.
