An Arduino-powered backlit Clemson Tiger Paw

Most people support their school or favorite sports team by buying a shirt or tuning into games. Jacob Thompson, however, took things one step further and created his own Arduino-powered, backlit Clemson Tiger Paw.

Thompson’s “WallPaw,” as he calls it, uses an Arduino Uno to receive signals from an infrared remote and to pick up sounds with a small microphone. This information is passed on to an Arduino Mega, which controls a five-meter-long strip of WS2812 LEDs to provide lighting effects.

He notes that it would be possible to use only one Arduino board for everything, but patterned his code after this tutorial that included two. The paw itself is cut out of wood and clear acrylic, allowing the lights underneath to shine through nicely.

You can see the build in action below and find more details on Thompson’s website here.

An interactive LED floor to get the dance party started

If you want a light-up dance floor for your next wedding or other special event, you can rent one; however, that can be quite expensive. On the other hand, you and your hacker friends can always build one. How hard can that be?

Turns out, very hard. While it may be simple to get one translucent panel to illuminate with LEDs, this 17-square-foot interactive dance floor used 64 panels with four lighting cells in each, for a total of 256 lighting arrays and 7,680 RGBs arranged as 2,560 addressable pixels.

Even with some advanced tools like a pick-and-place machine for PCB manufacturing, as well as a laser cutter, it still took volunteers many hours over the course of 11 months to get it working. LED control is accomplished via a Teensy 3.1, while 256 pressure switches under the surface are read by an Arduino Mega.

You can see more details of the impressive project in the video below (including a round of multi-player Dance Dance Revolution) and a few more technical details in AvBrand’s write-up here.

A cool infinity mirror-style bottle opener

In his quest to create “the coolest wall-mounted bottle opener in the entire world,” it would appear that YouTuber “Never Stop Seeking” has succeeded.

As seen below, the infinity mirror-style unit is made of plexiglass and two-way mirror film, and equipped with Arduino Uno-controlled RGB LED strips that are activated by a proximity sensor as you open a beer or soda. He even included a magnetic catch for his bottle caps!

Want to build one of your own? Good news, Never Stop Seeking plans on sharing more details along with a how-to video in the coming days.

Need desk lighting? How about 1,200+ LEDs?

After he’d just finished a project using RGB LEDs, Imgur user nolobot’s brother mentioned he needed a new computer desk. Most people would probably just let their brother buy one, others would make something out of wood, but nolobot instead decided to create something truly amazing using more than 1,200 WS2812 RGB LED modules, an Arduino Mega, aluminum extrusion, and translucent polycarbonate.

The Mega controls these LEDs with the FastLED library, which are sandwiched between a base piece of plywood and a strip of polycarbonate using custom spacers. This diffuses the light nicely, allowing for beautiful light animations directly on the desk’s surface.

You can find more on this awesome build on the project’s Imgur page!

Dot² isn’t your typical coffee table

Coffee tables are useful for putting coffee, food, or perhaps way too much junk on, but it’s 2017—we can do better than that! Akshay Baweja certainly has at least with Dot², an interactive piece of furniture that can run animations, display lighting effects, and play old-school games.

The Arduino Mega-based table features a matrix of 296 LEDs that shine up through sections of diffused acrylic, and uses a grid of foam board strips to keep each light in a square. Dot² can be controlled either by a PC running GLEDIATOR software, or via a smartphone using a Bluetooth connection and its own custom app.

The outside doesn’t look too shabby either. With an interesting wood pattern on the side, even when off it seems like there could be something more lurking just below the table’s glass!

Want to build one of your own? Head over to this incredible project’s Instructables page to get started. And, if you’d like to know more about how it’s controlled, check out Baweja’s app here or GLEDIATOR’s site for the computer software he used.

Interactive geodesic LED dome = extreme geometric fun!

We’ve all seen geodesic domes in one form or another, whether as a modern experiment, as housing from a bygone era, or perhaps as a gigantic structure in Orlando (technically a geodesic sphere). Jon Bumstead apparently wasn’t satisfied with current dome options, and instead created his own, integrating elements from programmable LED tables to make it interactive.

The resulting build is quite spectacular. Each triangular section able to be lit up with an RGB LED, and further information is output to five MIDI signals in order to produce sound. This means that up to five people can play the dome as an instrument simultaneously. If that wasn’t enough, the Arduino Uno-based dome is programmed to play a version of Simon or Pong, and can be set up to display a light show!

I constructed a geodesic dome consisting of 120 triangles with an LED and sensor at each triangle. Each LED can be addressed individually and each sensor is tuned specifically for a single triangle. The dome is programmed with an Arduino to light up and produce a MIDI signal depending on which triangle you place your hand.

Pretty cool, right? Head over to the project’s Instructables page to see more, or if you’d like information on constructing the dome itself, check out Domerama.

Control this Ohio home’s Christmas lights over the Internet

If you don’t want to bother putting up your own lights this year, you can just control Tom Hammond’s!

As seen on Good Morning America, Hammond recently put up a Christmas display that can be controlled via a simple online interface between the hours of 5pm and midnight (EST). The setup consists of an Arduino Mega along with a Raspberry Pi running Falcon Player, while the animations were created using xLights.

The website offers nine lighting options that anyone can select and play. Thanks to a webcam on Hammond’s property, the page even features a live stream that lets users see the animation they chose in real-time. However, due to the number of people trying to access it, the video is not always available.

Hammond, who lives in Akron, Ohio, told ABC News:

“I wanted people outside of my community to enjoy it. The nicest thing I got was an email from an older lady who lives with her mother who said they couldn’t decorate their house this year and she showed her mom my website and said that was one of the best gifts, that she got to decorate.”

Want a fun holiday distraction? Check out the Internet-connected lights here! You can also look at these other Arduino-powered dazzling displays to help get you in the festive spirit!
