Build Your Own Animated Turn Signals

Automotive lighting used to be strictly controlled, particularly in the United States — anyone remember sealed beam headlamps? These days, pretty much anything goes. You can even have an animated turn signal, because a simple flash isn’t fancy enough these days. You can get a scanning-LED turn signal on your new model Audi, among others. [Shravan] wanted this on their Mazda and set about building an animated turn signal and daytime running lights setup for their car.

It’s not a complicated build by any means; an off-the-shelf WS2812B strip provides the blinkums, an Arduino Nano the smarts. Using a modified …read more

Enter the Space Tunnel

What’s better than 1 string of LED lights? 96. That’s how many. Each string of the 96 has 60 ws2812b LEDs, for a total of 5760 individually addressable RGB LEDs.  That’s not the cool part of [jaymeekae]’s Space Tunnel installation, the cool part is that they’re interactive.

Starting out with some PVC piping, dark cloth was used as a backdrop and the LED strips were attached to it. Several power supplies are used to supply the voltage necessary and each strip controlled by FadeCandy chips which connect to, in this case, a Windows PC via USB. Initially, computer power supplies …read more

Beautiful Linear RGB Clock

Yup, another clock project. But here, [Jan] builds something that would be more at home in a modern art museum than in the dark recesses of a hacker cave. It’s not hard to read the time at all, it’s accurate, and it’s beautiful. It’s a linear RGB LED wall clock.

You won’t have to learn the resistor color codes or bizarre binary encodings to tell what time it is. There are no glitzy graphics here, or modified classic timepieces. This project is minimal, clean, and elegant. Twelve LEDs display the hours, six and nine LEDs take care of the minutes …read more

Huge Interactive Crossword

Give kids some responsible and challenging tasks, and you’d be surprised at the results. The “Anything Goes” exhibit at the National Museum in Warsaw was aimed as a museological and educational experiment. A group of 69 children aged 6–14 was divided into teams responsible for preparing the main temporary exhibition at the museum. Over six months, they worked on preparing the exhibition during weekly four-hour meetings. They prepared scripts, provided ideas for multimedia presentations, and curated almost 300 works for display. One of those was [Robert Mordzon]’s Giant Interactive Crossword.

The build is in two parts. The letter tiles, which …read more

WS2812B LED Clones: Work Better Than Originals!

Commodity electronics manufacturing is a tough game. If you come out with a world-beating product, like WorldSemi did with the WS2812B addressable RGB LED “pixel”, you can be pretty sure that you’re going to be cloned in fairly short order. And we’re all used to horror stories of being sold clones instead of what was ordered. But what if the clones were actually an improvement?

[Gonazar] bought some strips of “WS2812” LEDs and prototyped a project. When stepping up to larger production, he thought he’d go directly to WorldSemi. Long story short, the cheaper LED modules that he’d previously …read more
