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 ...

Motor control circuits in appliances including refrigerators, washing machines and air conditioners, need to operate more efficiently, reliably and safely while meeting cost requirements. With energy ...

The ongoing computerization of vehicle systems is leading to additional electronic control units (ECUs) and sensors to ensure effective control. So, Hall effect sensors are widely adopted for their ...

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 ...

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 ...
