https://www.edn.com/design/analog/4421567/Simple-circuit-enables-oscilloscope-art?utm_content=buffer4a139&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer I built the circuit from this EDN article. I could not find exactly right component values from my lab, so I used 180 pF capacitor and 41 mH inductor instead.  I “powered” the circuit with 1 kHz 7Vpp square wave from signal generator. Then I got this nice graphics on digital oscilloscope screen in XY →

https://jaycarlson.net/microcontrollers/ In 2017, we saw several new MCUs hit the market, as well as general trends continuing in the industry: the migration to open-source, cross-platform development environments and toolchains; new code-generator tools that integrate seamlessly (or not so seamlessly…) into IDEs; and, most notably, the continued invasion of ARM Cortex-M0+ parts into the 8-bit space. →

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 →

The Valve Wizard web page is about tube amplifiers. They have a very good document on grounding issues in tube circuits. So read their 16 page Grounding document to learn about grounding (both general information and tube amplifier specific information).   →

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 →

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.  →

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. →
