Keeping low-voltage outdoorlights illuminated takes some effort.Bulbs burn out, and connectionscorrode. HB LEDs (high-brightnesslight-emitting diodes) seem like acceptablereplacements, but most are ...

Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components to a 555. But you needn’t go so fancy! [The Design Graveyard] explains how ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

Gallium nitride-based LEDs and power transistors can be made on the same IC, according to scientists from Cornell University and the Polish Academy of Sciences. The trick is to used both sides of the ...
