PC Based Oscilloscopes are a great way to display your electronic measurements on to your computer screen. They offer all of the same functions that a traditional bench top Oscilloscope offers, except that they allow you to display your waveforms and readings on a computer instead of a CRT. Now what would you think if I told you that not only are these new Technological wonders very affordable, but now you can build one of these PC Oscilloscopes yourself. Many of us think of Electronic Kit building…

You can choose from wireless soldering tools like Butane Solder Irons, Solder Torches and Rechargeable Solder Irons or maybe an Instant Cool Solder Iron is on you list. Of course don’t forget about the traditional standbys like AC Soldering Guns and Soldering Irons…

There is no getting around that there are a lot of computers in the world. The percentage of homes alone that now have computers is staggering and with all these computers, some running literally around the clock, there had better be somebody available to repair them when they break down, and they DO break down. If you’re interested in the field of computer repair or even building computers…

A transformer consists of two or more coils wound on the same core. For power transformers, the core material is usually iron. For a radio-frequency transformer, the core material is usually ferrite or air. The basic property of a transformer is to change AC voltage. A transformer cannot change direct current voltage. A step down transformer has a lower AC output voltage at its secondary winding than the AC input voltage to its primary winding. Conversely, a step up transformer has a higher secondary than primary voltage. The transformer laminations or coating of shellac, enamel or varnish is to insulate adjacent turns from shorts between winding. I will not go too details about how transformer work and transformer calculation as you can read more details from most electrical and electronic transformers books…

Electronic test equipment, commonly called testgear, is equipment that is used to create stimulating signals and capture the responses from electronic devices under test. These devices are knowns as DUTS, Devices Under Test. Given this controls it is possible to prove the proper operation of a device through these tests, and deem them as being needed of repair or not.
Electronic test equipment is an essential element to any major electronics system. Ranging from a simple light bulb to expense and even automated tasks, electronic test equipment covers a very large range. In general it can be said that when developing electronic systems…
