Sometimes the most useful hacks are also the simplest ones. A case in point is the LED and resistor assembly that [Skippy] recently posted on his blog. The idea is to solder up some pre-made ...

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 ...

VCC has designed a series of LED sockets that feature a built-in current limiting resistor to provide optimal LED performance. VCC has designed a series of LED sockets that feature a built-in current ...

One of the questions that hobbyists ask over and over is how to select the value of a current limiting resistor for an LED. Usually the seat of the pants response is: “Subtract 2 V from the supply ...

The ubiquitous LED continues to expand frontiers and applications with a plethora of sizes, colors, and output lumens. Flashing LEDs that incorporate internal electronics for oscillation offer ...

Over on their YouTube channel [Science Buddies] shows us how to embed LEDs in soft robots. Soft robots can be made entirely or partially from silicone. In the video you see an example of a claw-like ...

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 ...
