Scarcely a lighting application exists that designers have not considered converting to solid-state lighting, especially as LEDs by leaps and bounds improve both the quantity and the quality of their ...
While addressable LED strips are all the rage, [Mike] from [mikeselectricstuff] has been working on an installation using the more basic two-wire strips that are simply controlled via PWM dimming.
White LEDs used in backlighting provide illumination for the pixels in liquid crystal displays. The LEDs are typically routed on one or two sides of the displays light diffuser, and biased with 20 mA ...
Over the years as I've built new PCs I've kept the motherboards from the replaced machines and hung them on the wall. A little bit of geeky artwork. I've decided to dress them up a bit and put them in ...
Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...
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 ...
The flashing is thanks to LEDs with a built-in, integrated flashing circuit and the nasty noise comes from a piezoelectric buzzer — both are available from electronics stores that sell ordinary LEDs.
Parallel LED drivers can be used to create the fast, square, high-current waveforms required for automated image processing. And it’s possible to extend such waveforms to higher currents by connecting ...
