What we really want is an ideal diode with zero voltage drop. Sadly, such a thing does not exist; however, there is a type of diode with a lower voltage drop — the Schottky diode. What we really want ...

Those portable shake-to-charge devices seem like a good idea, especially for the battery challenged, but how well does this sort of thing really work? Engineer Dave Johnson took this flashlight to the ...

For beginners, diode types can sometimes be a bit of mental gymnastics. If all it does is act like a magic pixie check valve, why are there so many kinds? Schottky diodes are typically hard to ...
