Discover hidden treasures using a DIY magnetometer

A magnetometer is an electronic device capable of measuring magnetic fields or magnetic dipole moment. Magnetometers are widely used for measuring the Earth’s magnetic field, in geophysical surveys, to detect magnetic anomalies of various types. If you fancy building your very own DIY magnetometer you may be interested in a Arduino project published to the Instructables website by maker Markus Opitz. His

3D PRINTED JOYSTICK USING SPHERICAL FLEXURE JOINT

One of the many advancements brought about by 3D printing is the rapid development of compliant mechanisms and flexure joints. One such example is [jicerr]’s joystick, which uses a pair of spherical flexure joints recently developed by researchers from Delft University of Technology in the Netherlands, See the videos after the break. Both flexure joint designs make use of tetrahedron-shaped

A DIY FLUXGATE MAGNETOMETER BASED CURRENT PROBE

A DIY FLUXGATE MAGNETOMETER BASED CURRENT PROBE

Introduction Current measurement can be really awkward when working with circuits. Voltage measurements are (usually) straightforward, but when it comes to current measurements the story is different. One typical approach is to insert a known resistance by breaking the circuit, and then measuring the voltage across it. This is difficult if one end of the

NVE Introduces Smart GMR Magnetometer

NVE Introduces Smart GMR Magnetometer

NVE Corporation announced the new SM124-10E Smart Magnetometer. The new sensor combines a Giant Magnetoresistance (GMR) sensor element with elegant digital signal processing. The versatile product can be used for current or proximity measurements. In-Plane Sensitivity Unlike awkward, old-fashioned Hall-effect sensors, GMR is sensitive in-plane for optimal current sensing and easy mechanical interfaces. A Slick,

Arduino Magnetometer

What are we building? Humans can’t detect magnetic fields, but we use devices that rely on magnets all the time. Motors, compasses, rotation sensors, and wind turbines, for example, all require magnets for operation. This tutorial describes how to build an Arduino based magnetometer that senses magnetic field using three Hall effect sensors. The magnetic

Adafruit Triple axis Magnetometer sensor board now available

Adafruit Triple-axis Magnetometer sensor board now available

Adafruit have announced the availability of its new Triple-axis Magnetometer offering a sensor capable of sensing ranges from +-50 gauss (+- 5000 uTesla!) with no range-setting required. For high resolution, you can read at 100 Hz update rate, and if you were not too concerned about a slight loss of precision the sensor can output

Digital Compass

This project uses SmartEverything Development Board’s on-board iNEMO 9-axis intertial module to make a digital compass. Story The Digital Compass project uses the SmartEverything Development Board’s on-board iNEMO 9-axis inertial module specifically the 3D Magnetometer. The magnetometer module is sampled for the x and y axis readings and then computed its compass headings. The project
