The pendulum is a neodymium magnet on the head of a bolt, dangling on a one foot aluminium chain. Below, a Hall Effect sensor rests atop an electromagnet — 1″ in diameter, with 6/8″ wire ...

This small PCB is designed to trigger your DSLR or mirrorless camera once its remotely-mounted hall effect sensor detects the presence of a magnet. The remote hall effect sensor. The idea is that ...

Subsequently, they developed a novel anomalous Hall sensor, achieving a low-frequency magnetic field detection capability of 23 nT/Hz 0.5 @1Hz and a Hall sensitivity of 7028 μΩcm/T, which are 3 times ...

Even with Hall Effect sensors, I found that sometimes small ... Needless to say, I am excited for what's to come in the world ...
