The proposed device is designed for “soft” on various radio and electrical household AC voltage of 220 V it is Known that the moment of switching devices containing a primary or secondary power circuits the capacitors of large capacity (high power audio amplifiers, switching power supplies and other devices), accompanied by a cast of current, which can reach tens of amperes.
Designed and made by me lighting device externally, and by construction, some nodes resembles the flashing beacons of special machines. But the purpose of it almost the opposite — creating a smooth bright light, and at low power lamps — at a considerable distance. Well, since the scope of the devices are different and their structures are substantial, but rather fundamental differences.
Remember, what is the simplest electrical circuit? The galvanic battery and light bulb connected by conductors through the switch (see the article “Ohm’s law” in the “M-K” N2 9, 1978). If such a circuit connection line length of about 30 cm to bring a compass, its magnetic needle will tend to become perpendicular to the conductor (Fig. 1).
More than two years have passed since then, as I have installed it on your motorcycle “IZH-Jupiter 4” contactless ignition on the basis of voskhodovskogo generator, switch 262 3734 and a homemade diode mixer (Fig. 1.). Making sure the reliable working of my creations, and colleagues conducted such an improvement to your motorcycles However there were questions like, “I drew on your chart — explain why me doesn’t work.”
With the approach of the New year interest in the “automation tree” increases dramatically. Everyone wants to decorate a beautiful Christmas tree with garlands of “live” light-driven commands to the electronic devices. One of them is the device to create the effect “running fire” — we tell today.
The inclusion of transformers on 400 Hz network, 220 V(50 Hz) using a ballast capacitor. If you look at the merits in diversity of industrial and self-made Amateur radio power supplies, it suggests the surprising conclusion. Basically they use the same (from a large item being sold) step-down transformers.
So, you are already familiar with the electromagnet, knows how to work the buzzer and electric bell (see “M-K” No. 8 this year). But there is a large group of Electromechanical devices, the main element of which is also an electromagnet. It’s the solenoid. That’s how they are.
Induction coil, in the last century invented Rumkorem, and is now used in experiments in physics. But now it is not fully satisfy the requirements of physical experiment creates interference, does not regulate the high voltage. consumes battery power, and feed the coil directly from the mains AC is impossible. We offer you to equip physical classrooms modernized version of the instrument developed on the basis of electronics.
There are many games in which, for example, the number of points scored by the player. is determined by throwing dice. It is easy to make and the electronic “dice” random number generator. Schemes of such generators and descriptions found in Amateur radio literature.
Compression, and adsorption refrigerators often fail due to the fact that they denied Electromechanical relays or breakers on the basis of the bimetallic plates. The first of them is used to trigger synchronous electric motors, serving a compression refrigerator system, and the second are the basis of the tracking systems and maintain at a predetermined temperature level freezer [1]. The reason for failure and the other is a burnout or a mechanical failure of the spring contacts in these devices. Ego especially applies to older models of refrigerators. And often you can see that, because of the insignificant, but hard to handle breakdowns (due to the lack of spare equipment) the throw is still quite usable machines. In the material made the attempt to remove such faults in household appliances.
