What is inside this old mains power filter? →

https://hackaday.com/2017/09/11/these-twenty-assistive-technologies-projects-won-1000-in-the-hackaday-prize/ This page introduces the winners of the Assistive Technologies projects. Take a look at many interesting open hardware projects. →

https://m.phys.org/news/2017-09-flip-flop-qubits-radical-quantum.html Engineers at Australia’s University of New South Wales have invented a radical new architecture for quantum computing, based on novel ‘flip-flop qubits’, that promises to make the large-scale manufacture of quantum chips dramatically cheaper – and easier – than thought possible. →

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: →

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 →

http://www.eetimes.com/document.asp?doc_id=1332192 At a Hot Chips event dominated by machine learning it was clear just about everyone is doing something in AI even though no one agrees on just what to do. Microsoft, Amazon and Baidu are pushing FPGAs to cloud. Google has Tensoflow ASICs.  Intel pitched four of its chip families as different tools for skinning the →

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 →

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 →

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 →

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 →
