I wanted to add an AC voltage meter to my electronics lab variac transformer output (0-275V AC). I decided to get a cheap Machifit AD16-22V 22mm Digital AC Voltmeter AC 20-500V Voltage Meter Gauge Digital Display Indicator with the following Specification: Model AD16-22V Mounting hole 22mm Voltage AC 20-500V Class of safety protection IP65 Color →
http://www.iflscience.com/physics/physicist-uses-regular-digital-camera-to-photograph-a-single-atom/ In 2012, Australian physicists captured the first image of a single atom. The process was painstaking and required a super-high resolution microscope. A new photograph taken by Oxford University physics PhD candidate David Nadlinger using only an ordinary digital camera shows a single, glowing-blue strontium atom hovering within a powerful vacuum chamber. It earned →
https://blog.hackster.io/build-your-own-touchscreen-ic-tester-for-just-25-7f10fab3815b IC testers help you identify an unknown IC by testing its input and output against a database of known components. You can follow Akshay Baweja’s tutorial to build your own. The total build cost should be around $25, and you’ll need a Arduino Mega 2560, a touchscreen display with an SD card slot, an →
http://www.iflscience.com/physics/physicist-have-created-a-new-form-of-light-that-can-interact-like-atoms/ American researchers have been able to create a three-photon bound state that represents a completely new form of light. As reported in Science, the researchers have been looking at complex interactions between photons for years. They obtained a two-photon state in 2013. →
https://medium.com/google-developers/computing-at-the-edge-of-iot-140a888007b We’ve seen that demand for low latency, offline access, and enhanced machine learning capabilities is fueling a move towards decentralization with more powerful computing devices at the edge. Nevertheless, many distributed applications benefit more from a centralized architecture and the lowest cost hardware powered by MCUs. Let’s examine how hardware choice and use case →
https://www.edn.com/design/test-and-measurement/4460312/High-speed-digital–112-is-the-new-56 EDN magazine reports that at DesignCon 2018, 112 Gbps was all over the conference and exhibit hall. Even just a year ago, engineers were still talking more about 56 Gbps speeds than 112. This year, all agree that 56 Gbps speeds have been achieved. It’s time to move on.
