Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Linear Hall-Effect Sensor. ... Moreover, an output voltage less than 0.4V will be counted as a sensor open-circuit state while higher than 4.2V denotes a sensor short-circuit condition. ... The ...

Autozero circuit that allows the user to automatically adjust the zero-point virtual ground terminal of the scope with the ...

Neopixels and Hall-effect sensors are mounted to custom PCBs that stretch the length of a row and are wired to an Arduino Mega with lots of IO. Game pieces are colorful fridge magnets.

Hall effect sensors are great, in that they never wear out or get noisy like potentiometers do. Another application where pots are a bad idea is in sensing the tape tension in a magnetic tape drive.

Selecting the correct bipolar latching Hall-effect sensor integrated circuit for electronic commutation in BLDC motors plays a big role in the efficiency of these motors and can, therefore, ...

The bipolar latching sensors, designated the OMH3075B and OMH3075S Series, contain a Hallogic monolithic integrated circuit, which incorporates a Hall element, a linear amplifier and Schmitt ...

The ATS682LSH from Allegro MicroSystems is a Hall-effect sensing integrated circuit and magnet combination that is intended for true zero-speed sensing of ferrous targets in two-wire applications. The ...
