Have you ever wondered how a magnetometer works? We sure have, which was why we were happy to stumble upon this article on simple homebrew fluxgate magnetometers. As [Maurycy] explains, …read more Continue reading Simple Stack of Ferrites Shows How Fluxgate Magnetometers Work
Your shiny new personal electronic device is likely to be designed solely as an app platform to run the products of faceless corporations, so the story goes, and therefore has …read more Continue reading The Apple Watch As An Ammeter
Diamonds are nearly perfect crystals, but not totally perfect. The defects in these crystals give the stones their characteristic colors. But one type of defect, the NV — nitrogen-vacancy — …read more Continue reading Quantum Sensor Uses Synthetic Diamond
The magnetic compass has been a crucial navigational tool for around a thousand years or so, perhaps longer. While classical versions still work perfectly well, you can now get digital …read more Continue reading Building a Digital Compass With An Arduino
When you find yourself doing a lot of work in 3D modelling, you occasionally wish for something more capable than the humble two-dimensional mouse. A space mouse is a great …read more Continue reading Build A DIY Space Mouse For A More Efficient CAD Workflow
Modern WiFi-enabled microcontrollers have made it affordable and easy to monitor everything from local weather information to electricity usage with typically no more than a few dollars worth of hardware …read more Continue reading Pi Pico Calculates Water Usage
On astronomical telescopes of even middling power, a small “finderscope” is often mounted in parallel to the main optics to assist in getting the larger instrument on target. The low …read more Continue reading StarPointer Keeps Scope On Target with Stellarium
If you have a motor and you’d like to know where the shaft position is, you are likely to turn to an optical encoder scheme. However, as [lingib] points out, …read more Continue reading Hall Effect Module Knows Where Your Motor Is
Researchers at the University of Sussex have demonstrated how an emerging type of quantum sensor could help doctors catch neurodegenerative diseases like Alzheimer’s earlier. The scanners precisely detect tiny changes in magnetic fields produced by firing neurons.
