A cadence sensor is a compact cycling device that measures pedaling rate in RPMs to provide real-time feedback.

Engine rpm is often equated to the heartbeat of an engine. If the rpm is too low, the engine shuts down, while very high rpm ...

Researchers from Japan have discovered a unique Hall effect resulting from deflection of electrons due to "in-plane magnetization" of ferromagnetic oxide films (SrRuO 3). Arising from the spontaneous ...

3D printed holder mounted to bike wheel, fitting precisely 38 magnetic spheres around its perimeter. Tedious math? Not if you make OpenSCAD do it. Off-the-shelf components are great; the world and our ...

Our Jacob really dug Corsair's MAKR 75 DIY keyboard, but wasn't entirely sold on either its price or lack of Hall effect switch compatibility. Well, the company's just announced another swish line of ...

BAE Systems is using knowledge from sea trials of trimaran demonstrator RV Triton (pictured) to inform its studies for a Deployed Sensor/Effector Platform. (Vosper Thornycroft) BAE Systems is looking ...

Quantum Hall is the quantum-level version of the Hall effect: a voltage produced as electrons flow through a magnetic field. In two-dimensional materials and at low temperatures the quantum mechanical ...

Mobile gaming keeps growing year after year, with roughly one-third of gamers playing exclusively on mobile devices. As portable gaming becomes more popular and powerful, the demand for proper ...
