WAKE UP ANY

WAKE ALL

Currently, widespread electronic TRAVEL CLOCK and similar clock with a miniature buzzer as sound source — a reminder about the occurrence of the deadline. However, a small volume of the regular signal, as shown, are often not sufficient in order to Wake up, for example, soundly sleeping man.

MYSTERIOUSLY FLICKERING LIGHTS…

MYSTERIOUSLY FLICKERING LIGHTS...It’s hard to imagine New year without festive lights and a Christmas tree with a mysterious flickering lights. However elektrogirlyandy industrial manufacturing not everyone is like: get bored of the monotonous flashing, and is harmful, they say it’s for health. I propose to replace these “flashers” an improvised device, lights which Shine like candles — with smooth change of brightness. Among its advantages are the simplicity of an electric circuit, which will be able to collect anyone, and the lack of scarce or expensive electronic components.

LASER SHOOTING

LASER SHOOTING GALLERY

Popular infantile pastime became now the so-called laser (light) pointer. Produced as a miniature working tool for teachers, lecturers and guides, it attracts the daring fans of science fiction an opportunity to play “the hyperboloid of engineer Garin”, highlighting the highly directional light beam of a particular item of interest at a considerable distance.

Materials about the specific features and infinite possibilities of lasers, including semiconductor, have been published in the journal “modelist-Konstruktor” (for example, No. 8’2001). Told also of how to adapt widespread laser pointer (LU) in a homemade optic dash, where it emitted the light pulse performs a function of photon bullets (see “modelist-Konstruktor” No. 12’2001). It was stressed that luminescence intensity and a number of other physical parameters LU depend on the voltage applied to the laser led.

RELAY PROTECTION

 RELAY PROTECTIONVoltage instability in the regional power lines, unfortunately, are not so rare. Especially during strong winds, when the wires of overhead lines of 0.4 can overlap. Because of the suffering of electro-, radio – and TV equipment, included in the housing network, where the voltage can suddenly become equal, say, 100, or Vice versa, 350 V. However, for my appliances I have five years did not worry, as the anomalous voltage in the network it protects a homemade relay system.

SVETOOPTIKA! ANY!

SVETOOPTIKA! ANY!

Most machines of lighting effects (AES), including homemade design for the decoration of discos, Christmas and other holidays (see “modelist-Konstruktor” No. 4 and 5 in 1995), can at best give only a reprogrammable combinations of light. Even with all the variety of used circuit design, these devices usually can not at least in a time interval arbitrarily change the order of playable effects and patterns. I offered as my development devoid of these shortcomings.

Solo Pro 319

Solo Pro 319The helicopter is equipped with the most detailed and realistic body of the helicopter Sikorsky UH-60. For maximum realism the helicopter is equipped with 4-blade main rotors, making the helicopter not only realistic, but also adds stability in flight. Helicopter applied electronic Flybarless system with three gyroscopes. High-performance brushless motor not only works for a long time without maintenance but also adds power to the helicopter. Patented system of removal of canopy makes it easy to change the battery and maintain the mechanics of the helicopter. RC helicopter Nine Eagles UH-60 is equipped with a gorgeous body scale, unique electronic 3G system with three gyroscopes and four-bladed main rotor.

ANTENNA IN HASTE

ANTENNA IN HASTE

Anyone who at least once in a lifetime chance to deal with wires, you can make original TV antenna (Fig.1) no worse than industrial zigzag.
The idea of this simple device I made in the years of his student life. The antenna was so successful that they continue to use it. The familiar “spread”, and they liked the design, which was given the name “Student”.

SINCE WATERED AUTOMATICALLY

IF WATERED AUTOMATICALLY

Offer favorite journal I developed a system of automatic watering and spraying plants, well-proven both in the room and in the greenhouse, Conservatory and flower garden. It includes two interrelated processes: “sensor — water” (Fig. 1) and automatic electronic control (Fig. 2). And if the first is easy even going to beginners, the second is better to entrust to those who have sufficient experience and knowledge in the field of electrical and radio engineering.
