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).

I picked up six new triple red LED fans from Xoxide and they arrived today. My plan is to revamp all of the cooling in my case with these new fans, but I want to modify the fans to be able to switch ...

Adding to the vendor’s family of LED drivers, the CAT3603 high-efficiency fractional charge pump targets high-volume, three-LED backlighting-display applications in cellular phones, digital still ...

I built a 16 x 9 array of modules using discreet R, G and B LEDs, and a pic to decode DMX512 to drive them. I've updated the diagram to use the Arduino 5V to run the chips instead of the 3.3V and ...

Troubleshooting electrical systems often begins with a simple question: Which fuse has failed? This compact seven-channel ...
