Recently, [Solder Hub] put together a brief video that demonstrates the basics of a Hall Effect sensor — in this case, one salvaged from an old CPU fan. Two LEDs, a 100 ohm resistor, and a 3.7 volt ...

Competitive gamers look for every advantage they can get, and that drive has spawned some of the zaniest gaming peripherals under the sun. There are plenty of hardware components that actually offer ...

The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if ...

Sensing current, especially in higher-voltage settings, is often a challenge. It’s generally more difficult than voltage sensing, as it is usually “invasive” and requires “breaking” into the ...

The TMAG5134 in-plane Hall-effect switch from TI offers a cost-effective alternative to magnetoresistive (MR) sensors for position sensing. An integrated magnetic concentrator enables detection of ...

We’ll beat everyone to the punch: yes, actually building a working Turing machine, especially one that uses a Raspberry Pi, is probably something that would have pushed [Alan Turing]’s buttons, and ...

After dealing with years of widespread reports of “stick drift” on the original Switch Joy-Cons, Nintendo watchers have been hoping the Switch 2 would make use of magnetic Hall effect sensors that ...

I’m admittedly not huge Switch fan, but my kids are - we have 1 original and 2 lites in our household. But as more details arise, the Switch 2 is less and less compelling. Let’s call it $500 (trariff ...

What is the Hall Effect? The Hall effect is a fundamental phenomenon in physics that occurs when an electric current flows through a conductor in the presence of a magnetic field perpendicular to the ...

Graphene-based Hall sensors represent a significant advancement in magnetic field measurement by harnessing the exceptional electrical and mechanical properties of graphene. Owing to its atomically ...

The NuPhy Field75 HE Keyboard packs Hall effect magnetic switches under those key caps. As a Mac user, you’re no stranger to cutting-edge technology, like the hottest new mechanical keyboards. But ...
