Ground Loop Break Circuits and Their Operation

Here is one piece of additional information to my ground loop postings. Ground loops can be introduced when different components in audio systems are connected with standard audio cables, and these loops can cause annoying interference. Grounded audi components generally carry significant currents in their ground returns. Texas Instruments Application Report SLOA143 – October 2009:

Whipping a cheap LED PSU into usable shape | EDN

http://www.edn.com/electronics-blogs/benchtalk/4458731/Whipping-a-cheap-LED-PSU-into-usable-shape This interesting article analyses some cheap mains AC to 12V DC power supplies and how thet can be fixed to work OK. With some modifications they can be used to provide power to LED lighting. The writer of this article has a continuing love-hate relationship with Cheap Chinese Chotchkes – in this case, 18W power

SYZYGY – Next generation FPGA connectivity

http://syzygyfpga.io/# Open standard for high-performance peripheral connectivity SYZYGY is FPGA-agnostic and is intended to work with products from all major FPGA manufactures including Xilinx, Intel, Lattice, and Microsemi. PMOD and SYZYGY can happily coexist in the FPGA space and even on the same carrier implementations! FMC and SYZYGY can happily coexist in the FPGA space

IoT: The Interference of Things | EDN

Relatively few connected gadgets will use wireline communications, the bulk of these devices will connect wirelessly over Bluetooth, Wi-Fi, cellular or something else. Some IoT devices will be designed to limit

DC-4.0GHz RF Fixed Attenuator

RF attenuators are a universal building block within the RF design arena. I neeeded some RF attenuators for my electronics lab. I found this cheap product  DC-4.0GHz RF Fixed Attenuator from Banggood. They seemed to have pretty good specfications and features considering that the price is just slightly over 7 Euros for three attenuators: Frequency

Shield Current Induced Noise

The Rane Library has many interesting audio relaed technical documents. The most famouse of them is Note 110 Sound Systems Interconnections – it is a classic. Just few days ago I happened to look around at The Rane Library, and found some really interesting material related to audio systems and ground loops: Grounding and Shielding

What PCB material do I need to use for RF? | EDN

http://www.edn.com/design/analog/4398951/What-PCB-material-do-I-need-to-use-for-RF-?utm_content=buffer44212&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer Is plain old FR-4 (also known as “Glass Epoxy”) PCB material suitable for use in RF designs? This question comes up time and again. Many say no, fewer say yes – who’s right? This article is from few years back, but still is valid. Besides RF applications you need to consider material with very

Chip Hall of Fame: Atmel ATmega8 – IEEE Spectrum

https://spectrum.ieee.org/semiconductors/processors/chip-hall-of-fame-atmel-atmega8 Atmel’s ATmega8 is one of the seed crystals of the modern maker movement. It’s at the heart of the first generation of the Arduino board. ATmega8 and its sibling chips such as the ATmega328P are used in current Arduino’s. The ATmega8 comes from the AVR line of microcontrollers, originally developed in the early 1990s by two students at the Norwegian University
