There are plenty of utilities out there to control keyboard LED indicators, but I'm rather interested in controlling the power LED on my headless 1U rackmount. While theoretically there are tons of ...
Reader Shawn wrote in with this power pickle: I have a Dell Studio Laptop. When I turn off my computer, the power-button light stays on and blinks. The only way I can stop it from blinking is to ...
This project is a simple universal Power LED Driver. The Power LED can be controlled by the built-in PWM signal generator or driven from an external drive signal depending on how the hardware is ...
In 2015, all economic indicators pointed to continued market growth for power electronics and LEDs, especially with IGBT modules boosted by EV/HEV industry and general lighting applications, a killer ...
High-powered LEDs are used in a growing number of applications, including automotive lighting, camera-phone flash, entertainment lighting, location lighting, landscape lighting, flashlights, bicycle ...
Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate in ...
144 LEDs total. Three sets of 48 in series connected in parallel. My problem is I don't know what value to use for R1. I'm thinking 600 ohm, but I really don't know how to calculate this. I'm making ...
