[John Crombie] had a crack at building one using linear Hall effect sensors and magnets as the detection mechanism to good — well — effect. Using the SS49E linear Hall effect sensor in pairs ...

As Hall effect and analog switches continue to rise, there’s one feature being slapped across every piece of packaging I’ve ...

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor ...

Raijintek has outfitted this keyboard with south-facing LEDs and magnetic/hall-effect switches from Heijin ... followed by a spill-resistant PCBA (Printed Circuit Board Assembly) and the bottom ...
