New Laser Technique Promises Photonic Devices Inside of Silicon – IEEE Spectrum

https://spectrum.ieee.org/nanoclast/semiconductors/optoelectronics/new-laser-technique-promises-photonic-devices-inside-of-silicon When a laser beam modifies a material, those modifications can either be temporary or permanent, and the change can also be either extremely subtle or drastic. The modified material starts responding differently to the laser beam. Scientists have taken advantage of these interactions to create structures within silicon that enable photonic devices. “We can also imagine

Introduction to Injection Molding – Hackster’s Blog

https://blog.hackster.io/introduction-to-injection-molding-d1597a442959 Unless your electronic product will be marketed solely to DIYers and electronics hobbyists it’s going to need an enclosure. Most likely this enclosure will be made of plastic that is injection molded to right shape. Injection molding is going be a big part of your journey to market so you need to understand injection molding

Understanding Certifications for Electronic Hardware Products

https://blog.hackster.io/understanding-certifications-for-electronic-hardware-products-7f7f983ae5b2  Most electronic products require multiple certifications in order to be sold. The certifications required depends on the product specifics and the countries in which it will be marketed. This article will mainly discuss certifications necessary in the United States, Canada, and the EU. 

Flip-flop qubits: Radical new quantum computing design invented

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.

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
