Concorde's air intake system, developed 40 years ago, is still leading-edge technology today. Flying at Mach 2—roughly 1,350 miles per hour—wind friction quickly raises the surface temperature ...

Radio amateurs often have a love-hate relationship with home-made inductors, sharing all kinds of tips and tricks as to how the most stable nanohenry inductor can be wound. But there’s another ...

This induction heater has a trick up its sleeve, too. Instead of using an air coil to generate heat in the cookware, this one uses an iron core instead. The project’s creator [mircemk] built an ...

Nowadays, for low-power and highly integrated electronic systems, embedded inductor-based SRs show several limitations that can be overcome by the use of inductorless SR architectures. This paper ...
