A Smart Table For Gamers

Posted on by

When makers take to designing furniture for their own home, the results are spectacular. For their senior design project, [Phillip Murphy] and his teammates set about building a smart table from the ground up. Oh, and you can also use it to play games, demonstrated in the video below.

The table uses 512 WS2812 pixels in a 32 x 16 array which has enough resolution to play a selection of integrated games — Go, 2-player Tetris, and Tron light cycle combat — as well as some other features like a dancing bird party mode — because what’s the point of …read more

A LED Strip Clock As Linear As Time

Posted on by

We love custom clocks here at Hackaday, and are always thrilled to see each inventive means of time-keeping. In a seldom-seen take on the familiar device, the [Bastel Brothers]’s LED Strip Clock’s sleek profile finds itself in good company.

The clock is a two-metre strip of 60 LEDs; every minute past the current hour corresponds to one lit LED, every fifth LED is turned to red in order to make reading minutes easier. So 3 red LEDs +3 green LEDs=18 minutes, with the hour marked by a third color. Sounds complex, but the [Brothers] are quick to say you get …read more

Ask Hackaday: What About the Diffusers?

Posted on by

Blinky LED projects: we just can’t get enough of them. But anyone who’s stared a WS2812 straight in the face knows that the secret sauce that takes a good LED project and makes it great is the diffuser. Without a diffuser, colors don’t blend and LEDs are just tiny, blinding points of light. The ideal diffuser scrambles the photons around and spreads them out between LED and your eye, so that you can’t tell exactly where they originated.

We’re going to try to pay the diffuser its due, and hopefully you’ll get some inspiration for your next project from scrolling …read more

Interactive Board Prompts Moves for Checkers and Chess

Posted on by

In terms of equipment, chess and checkers are simple games — just a handful of pieces and a checkered gameboard. The simplicity belies the underlying complexity of the games, though, and goes a long way toward explaining their popularity over the millennia.

Increasing the complexity with an interactive game board for chess and checkers might seem counterintuitive, then. But [Bogdan Berg]’s project aims to not only teach checkers and chess but to make games a little more exciting and engaging. Looking a little like a tabletop version of the interactive dance floors we’ve been seeing a lot of lately, the …read more

Build Your Own Animated Turn Signals

Posted on by

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

The Smartest Smart Watch is the One You Make Yourself

Posted on by

If you’re building a smart watch these days (yawn!), you’ve got to have some special sauce to impress the jaded Hackaday community. [Dominic]’s NeoPixel SmartWatch delivers, with his own take on what’s important to have on your wrist, and just as importantly, what isn’t.

There’s no fancy screen. Instead, the watch gets by with a ring of NeoPixels for all its notification needs. But notification is what it does right. It tells [Dominic] when he’s got an incoming call of course, but also has different flashing color modes for SMS, Snapchat, and e-mail. Oh yeah, and it tells time and …read more

NeoJoints Make WS2812 LEDs Even More Fun

Posted on by

What’s more fun than individually addressable RGB LEDs? Many, many individually addressable RGB LEDs. What’s more fun than all the miscellaneous soldering involved in connecting many of these cheap and cheerful strips together? Well, basically anything. But in particular, these little widgets that [todbot] designed help make connecting up strips of RGB LEDs a snap.

[todbot]’s connectors aren’t particularly groundbreaking, but they’re one of those things that you need the moment you first lay eyes on them. And they’re a testament to rapid prototyping: the mounting holes and improved routing patterns evolved as [todbot] made some, soldered them up, mounted …read more

Closer Look at Everyone’s Favorite Blinky

Posted on by

Admit it, you love looking at silicon die shots, especially when you have help walking through the functionality of all the different sections. This one’s really easy for a couple of reasons. [electronupdate] pointed his microscope at the die on a WS2812.

The WS2812 is an addressible RGB LED that is often called a Neopixel (a brand name assigned to it by Adafruit). The part is packaged in a 5×5 mm housing with a clear window on the front. This lets you easily see the diodes as they are illuminated, but also makes it easy to get a look at …read more
