800+ LED Wall With Diffuser Panel is a Work of Art

LED Wall

What happens when you take over 800 individually addressable super bright RGB LEDs and house them in a giant diffused panel? You get awesome. That’s what you get.

[Epoch Rises] is a small electronic music and interactive technology duo who create cool interactive projects (like this wall) for their live shows and performances. They love their WS2812B LEDs.

The cool thing about this wall is that it can take any video input, it can be controlled by sound or music, an iPad, or even generate random imagery by itself. The 800 LEDs are controlled by a Teensy 3.0 using the OctoWS2811 library from Paul Stoffregen which is capable of driving over 1000 LEDs at a whopping 30FPS using just one Teensy microcontroller. It works by using Direct Memory Access to send data over serial into the Teensy’s memory and directly out to the LEDs with very little overhead — it is a Teensy after all!

The Megascroller, For Video Games In The Round

megascroller

The folks at NYC Resistor have a thing for circular displays, it seems. Their earlier Hexascroller was a ceiling mounted display with six 30×7 displays – good enough to display the time and a few textual message in six directions. The Octoscroller bumped up the display capability with eight 16×32 RGB LED panels. Now the Megascroller, a 32-sided 512×64 display is hanging in the hackerspace, complete with 360° Mario and Pong.

The Megascroller is one of [Trammell Hudson]‘s projects, constructed out of sixty-four 32×16 RGB LED matrices. That’s an impressive amount of controllable LEDs, that required a lot of processing power: namely, the BeagleBone-powered LEDscape board used in their earlier Octoscroller

As far as applications go, they naturally have Pong, but a more interesting application is the side-scrolling Mario that requires you to move around the display as you play. You can check out a video of that below.

If you’d like to see the Megascroller in person, as well as a whole bunch of other crazy blinking interactive projects, NYC Resistor is holding a an interactive show this weekend, beer provided.
