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.
Good response – what is it? More correct to say “speed of reaction” is the time that elapses between receipt of the alarm to the adoption of concrete measures. For example, the driver reaction time of 0.4 to 1 s depending on the complexity of the track conditions and the type of the vehicle managed by it.
Efficient and reliable operation of electronic devices depends largely on the temperature regime of each individual circuit element, especially if they work for 24 hours a day. Temperature, in turn, depends on the power load and output (key) cascades of stability of supply voltage.
The creation of the original screen is of considerable importance in the design of light and music. Svetoteni fall primarily into two types with distinct colors and gammopathies — there takes place a combination of colors.
It is not difficult to do even the novice hobbyist. And materials needed for this available.
Turn indicator, which are explained in this article is intended for motorcycle “Java”. The advantage of the self-made device before the industrial — low inertia: the scheme starts to work immediately after switching on the battery.
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.
Has long been noted that the viewing of slides, movies, TV shows, as well as any other visual activity (reading, drawing, and examined under a microscope), in unfavourable lighting conditions causes a large overvoltage of view.
