Last year I made a posting on Cheap fiber optic visual fault locator. It told about 1mW 5KM Red Light Pen Visual Fault Locator Fiber Optic Laser Cable Tester Meter puts out highly visible red light into a fiber optic cable that has ST, SC and FC optical connectors.The universal fiber connector worked well with single-mode →
https://thenextweb.com/contributors/2018/02/21/batteries-holding-tech-breakthroughs-whats-happening-now/ Despite incremental advancements, batteries haven’t changed all that much over the past decade. Major brands are investing in better environmental efficiency, and small tweaks that improve storage and performance, but the typical “battery” is still fundamentally the same. There is stagnation in the realm of batteries. →

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. →
