Magnetoresistive Sensors
Introduction: Magnetoresistive sensors are devices that detect changes in magnetic fields by measuring variations in electrical resistance. They are highly sensitive and commonly used in applications such as position sensing, data storage, and current measurement, leveraging the magnetoresistive effect of certain materials. Working principle: Magnetoresistive Effect: The fundamental principle behind magnetoresistive sensors is the change… Continue reading Magnetoresistive Sensors
Using Mouse Ears in 3D Printing with OrcaSlicer
3D printing small parts or models with narrow contact areas often leads to adhesion issues. Warping, curling, or outright detaching from the build plate are common problems, especially when printing with materials like ABS. One proven solution is the use of “mouse ears”, a simple yet highly effective adhesion aid. What are mouse ears? Mouse… Continue reading Using Mouse Ears in 3D Printing with OrcaSlicer
Constructing a Fritzing part using Inkspace
Fritzing uses SVG graphics for the visual representation of parts (breadboard, schematic, PCB views). Inkscape is a popular open-source vector editor you can use to create and edit these SVG files. Steps to create a Fritzing part graphic in Inkscape Plan your part Determine the views you need: Breadboard view: realistic visual appearance. Schematic view:… Continue reading Constructing a Fritzing part using Inkspace
