Collaborate Disseminate
It’s commonly said that the great thing about standards is that there are so many of them. Of course, that’s talking about competing standards. But there’s another kind of standard that …read more Continue reading A Savage Discussion of Measurement And Accuracy
LinuxCNC contributor and machining enthusiast [Andy Pugh] is certainly not afraid to try making specialised tools to see how well they work out, and this time he’s been busy making …read more Continue reading A Simple Touch Probe Made With Basic Tools
The name Gladys West is probably unfamiliar, but she was part of creating something you probably use often enough: GPS. You wouldn’t think a child who grew up on a …read more Continue reading Gladys West Modelled the Earth So That We Can Have GPS
A monochromator is an optical instrument that permits only a narrow selection of wavelengths to be transmitted from a source, and the particular model [Doug] obtained renders visual light monochromatic …read more Continue reading Vintage Monochromator Makes Monochromatic Light, Mechanically
Last year, as my Corona Hobby™, I took up RC plane flying. I started out with discus-launched gliders, and honestly that’s still my main love, but there’s only so much …read more Continue reading You Can’t Fix What You Can’t Measure
The commoditised PC is the most versatile tool many of us will own, and since it has been around for a very long time it is also something that can …read more Continue reading Your PC Sound Card As A Sensor Input
We’re pretty familiar with budget resistor-based bend sensors at this point, but this sensor is in a totally different class. Instead of relying on resistive elements, [Useok Jeong] and [Kyu-Jin Cho] devised a bend sensor that relies on geometric properties of the sensor itself. The result is a higher-fidelity measuring …read more

When it comes to the Internet of Things, many devices run off batteries, solar power, or other limited sources of electricity. This means that low power consumption is key to success. However, often these circuits draw relatively small currents that are difficult to measure, with plenty of transient current draw …read more

[Darlan Johnson] was working on a wearable project and needed a way to measure the change in voltage and current over time.
Most measurement tools are designed to take snapshots of a system’s state in a very small window of time, but there are few common ones designed to observe …read more

[Ryan Schenk] had a problem: he built the perfect surfboard. Normally that wouldn’t present a problem, but in this case, it did because [Ryan] had no idea how he carved the gentle curves on the bottom of the board. So he built this homebrew 2D-scanner to make the job of …read more
