- 07.02.2023 - 22:39When restoring vintage tube-type radios, it's essential to have a proper power input system. This system typically includes an isolation transformer, a Variac, and a current limiter. The Variac and current limiter protect the radio or other electronics from overvoltage and overcurrent, while the isolation transformer protects the technician fro...
- 11.10.2021 - 23:36IntroductionEvery electronic device you can consider containing a PCBis still the best and most reliable way of connecting electronics components. The PCB stands for Printed Circuit Board, on which electronic components are soldered on pads connected by conductive lines. It is still called printed, but the technology goes beyond the printing pr...
- 10.06.2020 - 23:19TDA2822:The TDA2822 is a Dual Audio Amplifier IC, which means it has two Op-Amps inside its bundle, and they are normally utilized for sound intensification as a result of their wide data transfer capacity gain. The two yields can convey 250 milliwatts yield power. This IC can be utilized in compact sound frameworks, pre enhancers, listening de...
- 09.06.2020 - 23:45This amplifier is a combination of two amplifiers class A and class B. class B amplifier has a problem of distortion and class A amplifier has low efficiency problem. The class AB amplifier eliminates both of these problems and utilize the advantages of these two amplifiers.Class AB amplifier operates as a class A amplifier when the power of ou...
- 06.05.2020 - 23:49I have recently checked out www.utsource.net to order some parts for one of my projects. When you visit to the site’s home page it is prompted a part selection for multiple parts and also order placement links. In both methods parts have to be selected manually. I was more interested in more easier BOM tool. Almost every electronics com...
- 04.07.2018 - 03:18A number of different communication modules for use with the Android I/O board have been introduced in various articles for the board. These modules have used WiFi, Bluetooth or USB. However, there is one module for the Android I/O board that's missing, which uses one of the most popular communications standards: Ethernet. This article describe...
- 06.11.2017 - 23:49The building and tweaking of audio equipment is something that occupies many enthusiasts. It is very satisfying and nothing beats listening to music on equipment that you have built yourself, even partially. In this installment of WebScouting we'll show you that you don't need a complex design, or a large number of components, to produce a...
- 24.09.2017 - 16:47It has been nearly three years since we presented our last power amplifier project in Elektor - the Q-Watt Audio Power Amplifier [1]. That was a standard class AB power amplifier with high output power and low distortion. Since then a large number of audio enthusiasts have built their own copy of that amplifier. With the design presented here, we a...
- 09.09.2017 - 23:54If you feel like replacing the VHF-FM radio in your car with something more modern offering DAB+ reception too, you'll discover that combination receivers have two separate antenna inputs. That's because two individual antennas are required. But this RF combiner makes it possible to connect both inputs to one standard car antenna.I bega...
