Everyday electronic items are not just molded from plastic and metal and then shipped to the store for you to buy. Electronics include a huge array of circuits, transistors, resistors, capacitors, etc all arranged perfectly to work together. This specific field of electrical engineering allows devices like the cell phone to work for you when you need to make or receive a call, let you watch tv, or even know what time it is on your digital watch. Electrical Engineering is also involves a study of various machines such as AC DC motors. These common devices are used for many purposes in industry as well as in the domestic sector. Learn about how they work, how they’re built and how they are used in our daily live. Once you understand basic circuit theory you can even start building your own electronic devices! Find instructions and guides here!
Electrical testing and measurement devices can tell you if a circuit or wire is energized as well as tell you how much voltage or current an electrical circuit is carrying. Other types of testing devices can tell you if a network cable is connected properly or if there is continuity in that cable.
Learning and mastering electronic concepts may not be a short term process. Rather it involves relentless and comprehensive study of the subject, both theoretically and practically. The articles included here provide a clear picture of the various aspects of working with electronic circuits.
Are you an electronics novice? Or a hardcore electronic hobbyist who wants to learn how to make useful electronic circuits? Either way, you have reached the right destination! Here we introduce some very cool and interesting electronic hobby circuits that you can build.
The proposed mini-electricity generator project is very simple to build and can be used by students as a school project, or just for hobbyists. The set up can be used to charge a battery with electricity produced from wind power.
You may be a good bicycle rider, but wouldn’t you love to know how fast you really ride? The article presents an easy electronic circuit which can be integrated to your existing bicycle dynamo to get an instant LED illuminated speed indications, the moment you start peddling.
A DC series motor converts electrical energy to mechanical energy. Its principle of operation is based on a simple electromagnetic law that states that when a magnetic field is created around current carrying conductor and interacts with an external field, rotational motion is generated.
An ideal Pulse Width Modulation circuit using the IC 555 is explained in the article. Here the configuration shows how the above mode of the IC can be used for controlling DC motor speeds; however the design can be actually used for a number of different relevant application purposes.
A built-in oscillator stage in the IC 4060 chip makes it truly versatile and applicable for numerous different applications. It can be easily configured as an accurate timer, oscillator, flasher, clock generator, or sequential timer, and that’s just the beginning of its usefulness.
Shunt DC Motors operate on direct current. As such, the field windings and armature are connected in a parallel combination, and in electrical terminology a parallel combination is known as a shunt. This type of motor is a “shunt-wound” DC Motor and the type of winding is called a shunt winding.
This IC is basically made up of two D-type flip flop modules and set/reset asynchronous toggle inputs. As the name suggests, the IC is primarily used as a bistable for toggling the output stage of a particular circuit, and it is fundamentally incorporated in most electronic circuits.
