Flashing circuits are very interesting. They grab your attention and can be used in many applications. They consume very little energy and a single cell can last as long as 12 months. This is the simplest circuit capable of alternately flashing two LEDs.

The process is the same. A computer engineer is trying to create electrical components on a piece of semiconductor such as silicon. كتابة مدونة حول هذه المشاركة.

Amlost any non-trival electrical circuit will contain some resistors in series and parallel, therefore it is necessary to be able to work out the equivalent resistances of the network. كتابة مدونة حول هذه المشاركة. Resistors are made in several different ways, and although they just look like blobs on a wire, they are quite interesting.

The story of the invention of the screwdriver. Once Robertson had conceived the notion of a square-headed screwdriver, he toyed with various manufacturing methods until he was able to produce screws with a square-shaped imprint on their heads. When the correctly-sized driver is inserted into a corresponding screw, the user can rortate the driver horizontally without fear of the driver slipping. Because the driver is self-centering, only one hand is needed for rotation.

They are also rated by the maximum current they can pass. Negative voltage regulators are available, mainly for use in dual supplies. Please see the Electronics in Meccano website for more information about voltage regulator ICs.
