This is part 2 in a series where I explain how diodes, LEDs and solar panels work. See part 1 if you’re a fan of diodes doing ...

I’m something of a headlight nerd. In a previous life, I retrofitted HID projector headlamps onto my 2009 Honda Civic Si for better light output. I’m planning a similar project for my beater 2015 VW ...

The polarity markings on LEDs (Light Emitting Diodes) seem to be a common cause of confusion. The polarity may be indicated by a flat section on one side of the body or by one lead being shorter than ...

In a previous article, we explored the behavior of an LED diode as a small light source. We have seen how important a protection resistor is to light up this component. In this article, we will ...

GE Global Research, the centralized research organization of the General Electric Co., has developed an ideal carbon nanotube diode that operates at the "theoretical limit," or best possible ...
