Time will always be“of the essence” for professional engineers and amateur enthusiasts alike. This can certainly be said about the process of designing circuits involving Light Emitting Diodes (LEDs).

You’ve probably heard of light-emitting diodes, a type of energy-efficient light. While they’re good for practical reasons—say, illuminating a room or a passageway—they can also add a little bling to ...

This custom circuit board picks up some of the pieces from a wall wart to drive a high-power LED. The basic concept is to keep the high-voltage components and swap out the low voltage ones for parts ...
