In the quest to add some mood lighting in his basement, [Mohonri] found an infrared wireless remote that is able to control several RGB LED strips. The only problem with this remote is the inability to control it via a wall-mount panel or even a computer. Obviously this would not stand for such a swank basement, [...]

[Alex] built an add-on board for his TI launchpad that lets him use it as a wireless controller for an RGB lamp (translated). As you can see above, the board has a pair of female pin-headers which make it easy to install or remove the board. This way you can use it for other projects without [...]

[Rick Osgood] wanted to build a color sensor that could be held up to any object to get RGB color values. He originally started with a photoresistor and a few LEDs, but couldn’t get that to work reliably. [Rick] finally completed his color sensor after finding a digital luminosity sensor on Adafruit, ending up with a [...]

[Asher Glick] wrote in to share a project he has been working on with his friend [Kevin Baker], a 4x4x4 RGB LED cube. The pair are students at Rensselaer Polytechnic Institute and also members of the newly-formed Embedded Hardware Club on campus. As their first collaborative project, they decided to take on the ubiquitous LED [...]

[Craig Lindley] recently finished building his own RGB LED cube project. It’s made up of four layers of 4×4 LED grids, but you may notice that the framework that supports the structure is not the usual ratsnet of wires we’ve come to expect. They’re actually long, thin circuit boards. [Craig] grabbed the Rainbow Cube kit sold [...]

[Fjord Carver] brings together an RGB LED and CdS Photoresistor to make a color sensor. Those Cadmium Sulfide lights sensors usually have a very wide swing of resistance when exposed to varying levels of light sensitivity. That makes for great resolution when reading them using the ADC of a microcontroller. The LED comes into play by shining [...]

We can order seven segment displays in red, green, yellow, or blue all day long. One thing we haven’t seen is an RGB segmented display, so [Markus]‘ project is really interesting. He took a stock seven segment display and modded it into an RGB display. After taking a Dremel to the back of the stock [...]

If you ask us, there’s no substitute for learning by doing. But often the hardest part of acquiring new skills is coming up with the idea for a project that utilizes them. [Mike Rankin] wanted to develop a project using laser cut acrylic, and settled on building a control box for an RGB LED strip. [...]

We’re no strangers to POV time pieces around here, but something about them never gets old. Whether they use a ring of LEDs to draw clock hands, or an intricately cut HDD platter to replicate LCD segments, we love seeing them. [David] sent in this hard drive POV clock built by a fellow named [Kly], [...]

A user named [BOcnc] on the rcgroups forums just posted his RGB POV helicopter blades. The two blades are attached to the heli just as any other whirlygig. The electronics, though, are mounted underneath the blade with a battery pack. We covered a build last year that demonstrated weight added to a spinning blade won’t [...]

This year, students working for Texas Instruments as part of their Co-op program were challenged to construct a project around the company’s MSP430 microcontroller. A team of three students, [Max Thrun, Mark Labbato, Ian Cathey] decided to build something that would fit perfectly in any college student’s dorm room – an RGB LED coffee table. [...]

[Mathieu] was on holiday in China and picked up some fun toys while perusing the numerous electronics markets there. The most interesting things he discovered were a pair of RGB LED matrices. They came in two different flavors, one made for indoor and one for outdoor displays, sporting a 64×32 and 32×16 resolution, respectively. If [...]

Instructables user [lincomatic] was doing some home decorating and was trying to find something that would really tie the room together. He decided against adding a nice rug, a light fixture is what he was after. Rather than settle on a simple lamp for the corner of the room, he constructed an 8×8 RGB LED [...]

[Ben's] introduction to microcontrollers was this fun little gift he calls the “tilty cube”. It is an acrylic box with 3 LEDs mounted inside that changes color based off of how you tilt it. Sounds like a fun toy, and a good project to learn with. [Ben] chose the PIC12F615 as the brains and laid [...]

[Johannes Agricola] recently held a workshop at the Peace Mission in Goettingen, Germany where he shared his RGB LED flowers. The small round PCB hosts an ATmega88 microcontroller which is running the V-USB stack so that the unit can be controlled by a computer. Each flower blossom is an RGB LED connected with four enameled wires [...]

[Jay Collett] was having trouble seeing his keyboard when the room was dim. But throwing a light under the desk just didn’t seem cool enough. Instead he built an RGB light board that is controlled by his desktop. The board is based around an ATmega328 with the Arduino booloader. He etched a single-sided PCB to [...]

Adafruit Technologies has announced the winner of the Open Source Kinect contest. [Hector], who we mentioned yesterday has won, providing both RGB and depth access to the device.  Some of you were asking at that time, why the contest was not over yet. Well, Adafruit had to verify. The image you see above are of [...]

[Stan] built this LED matrix using a 16×16 grid of RGB LEDs. He built the hardware and wrote some subroutines to randomize the colors. He’s not using PWM because frame buffering is not feasible for the 1k SRAM limit of the ATmega168 he used. Instead, shift registers drive the lights which can be mixed to [...]

This is [Michael Ossmann's] RGB LED stroboscopic guitar tuner. If his name is familiar that’s because we mentioned he’d be giving a talk with [Travis Goodspeed] at ToorCon. But he went to DefCon as well and spent the weekend in his hotel room trying to win the badge hacking contest. Despite adversity he did get [...]

[Johncon] wrote this fantastic instructible showing us how to make an RGB LED headband. This should come in really handy the next time we find ourselves needing one… it happens. He picked up this little RGB LED strip while on a business trip to Shanghai. He had to reverse engineer the chip that controls each [...]

[Simon Inns] turned out this VU meter with a 16 RGB LEDs. He’s using three 16-bit TLC5940NTG LED drivers for the project. They’re not cheap chips but they do a great job. If you were looking to save on parts [Simon] found there’s more than enough brightness and any loss due to multiplexing would not [...]
