Zen digesters” rarely fart. “Hydrogen hyperproducers” fart a lot. Scientists are investigating what is typical.

While searching for new products on AliExpress, I came across the SayoDevice OSU O3C, which looks very similar to other macro ...

In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

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 ...

NewTek Sensor Solutions has launched the RVD Series Hall Effect angle sensors. The combination of Hall Effect technology and the non-contact design of these sensors measures rotational position ...

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 ...

Allegro’s ACS37200 200-A Hall current sensor slashes power dissipation with its 50-µΩ shunt, offering 1,400 V of isolation in a compact PSOF package for high-voltage systems. How the ACS37200’s 50-µΩ ...
