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

Berkeley’s Tiny Flying Ionocraft Can hover using No Moving Parts

Berkeley’s Tiny Flying Ionocraft Can hover using No Moving Parts

A research team from UC Berkeley Univercity (Daniel S. Drew, Nathan O. Lambert, Craig B. Schindler, and Kristofer S. J. Pister) has designed and build mini microbot that is capable of taking flight without any motor or moving part. This is all achieved using electrohydrodynamic thrust to provide lift, which is a technique to create air-flow

Comparing MEMS and Electret Condenser Microphones

Comparing MEMS and Electret Condenser Microphones

MEMS Microphone Basics MEMS microphones are constructed with a MEMS (Micro-Electro-Mechanical System) component placed on a printed circuit board (PCB) and protected with a mechanical cover. A small hole is fabricated in the case to allow sound into the microphone and is either designated as top-ported if the hole is in the top cover or

NEVER FORGET TO TURN ON THE COOKER HOOD AGAIN

NEVER FORGET TO TURN ON THE COOKER HOOD AGAIN

The cooker hood is a wonderful invention for removing excess fumes and steam from the kitchen. But like all electrically-powered devices, it only works when it is turned on. This was the problem facing [Peter], whose family are enthusiastic cooks who frequently forget to hit that switch. His solution? An automatic cooker hood switch that comes
