Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...

I'm returning to an old project today to fix it since it got broken during my recent move. This toy I made for my dog is very fun project where an Arduino controls two servos so they can move a laser ...

You may or may not be reading this on a smartphone, but odds are that even if you aren’t, you own one. Well, possess one, ...

Astronomers with the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) have used data from the project to make the ...

The Z-Trak Express 1K5 3D laser profiler for in-line 3D measurement and inspection delivers high-speed 3D inspection with real-time processing, achieving a maximum profile rate of 5,000 profiles per ...

NASA has been practically synonymous with advanced computing for nearly 70 years. To this day, the National Aeronautics and Space Administration continues to accomplish the impossible with computers.

When NASA installed a unique imaging sensor on the outside of the International Space Station, the original intent was to help map the composition of minerals on the Earth's surface. Far from the only ...

This project presents a portable Arduino-based digital instrument for railway track inspection that measures super elevation (cant), track gauge, and rail temperature. Built around an Arduino Nano, ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

NASA’s EMIT sensor advances space technology to track ocean debris by applying imaging spectroscopy to identify material specific spectral signatures from orbit. Although EMIT was launched in 2022 to ...

With Christmas a little over two weeks ago, one might be scrambling to find a gift for a loved one, friend, or family member. If you’re familiar with Arduino or Raspberry Pi and have a free weekend, ...
