Interactive RGB Block Wall Transforms Arcade into Immersive Gaming Hub

Nick Lombardy, a maker from Chattanooga, Tennessee, was commissioned to construct "BoneBlocker," a gigantic gaming device for his local barcade, Coin-Op. To create BoneBlocker, he implemented WS2812B LEDs, hot glue, a sturdy wooden frame, and Ethernet-connected WT32-ETH01 boards. The game is run on a Node.js webserver and Three.js, while the controller is a smaller version of the display mounted on an X/Y pivoting mount with 185 LEDs for player feedback.

Giant, Interactive RGB Block Wall Transforms Local Arcade into Vibrant Entertainment Hub

Amidst the bustling streets of Chattanooga, Tennessee, Nick Lombardy, an avid game enthusiast and maker, stumbled upon an opportunity that would redefine the local arcade scene. Coin-Op, a beloved barcade frequented by Lombardy, was ready to unveil a colossal gaming device that would captivate patrons and ignite their imaginations.

A Technological Masterpiece Takes Shape: The BoneBlocker Wall

Lombardy, armed with his expertise in LED technology, embarked on a meticulous journey to construct the pièce de résistance of the arcade—a towering gaming wall christened the "BoneBlocker." Meticulously assembled from an astounding 112 glass blocks, each meticulously arranged within a sturdy wooden frame, this colossal structure promised to illuminate the arcade with its vibrant display of images, animations, and interactive gameplay.

Lighting the Wall: A Balancing Act of Power and Efficiency

The wall's brilliant illumination posed a daunting engineering challenge. The sheer number of RGB lights required to create such a vast display threatened to consume an exorbitant amount of power. Through careful calculations, Lombardy arrived at an ingenious solution—to illuminate only half the LEDs in each column, effectively reducing the light density by half and the power draw by a significant 1500 watts.

Block by Block: Assembling a Colossal Puzzle

With the power considerations resolved, Lombardy meticulously assembled the wall one block at a time. Hot glue flowed freely as the LED strips unraveled from the wall's summit and cascaded gracefully downwards. Each strip functioned independently, ensuring that any potential faults would not plunge large sections of the system into darkness. The strips terminated at a series of buses that served as the central hub for power distribution and signal control.

Signals Unchained: Unlocking Fast-Paced Gameplay

Lombardy initially employed an Arduino Mega 2560 to control the vast array of lights, leveraging the FastLED library for rapid data output. However, the Mega's limited processing speed and USB interface proved inadequate for the desired gameplay smoothness. To overcome this hurdle, Lombardy replaced the Mega with eight WT32-ETH01 boards boasting Ethernet connectivity and programmable via a web interface through WLED. The addition of logic-level converters paved the way for the seamless integration of custom software.

Marrying Game and Screen: A Symbiotic Relationship

Traditionally, LED matrix projects directly execute games on the microcontroller. However, the distributed nature of the BoneBlocker's control scheme and the demand for rapid screen updates necessitated a more powerful host. Lombardy ingeniously crafted his Tetris-inspired game using Node.js and the renowned Three.js library for 3D graphics. With each update, the game engine seamlessly communicates with the WLED web API, orchestrating the display of pixel colors on the wall in real-time.

Interactive Controller: Bridging the Physical and Digital Realms

Patrons engage with the game through a miniature version of the display, mounted on an X/Y pivoting mount akin to a traditional joystick. This controller, however, boasts a unique twist: its top surface is a glass block featuring 185 LEDs, capable of displaying mesmerizing animations and providing intuitive feedback to the player. The block, speaker, and sensors are cleverly integrated into a wooden podium structure, replicating the authentic arcade cabinet experience.

Illuminating the Arcade: A Symphony of Light and Sound

As showcased in Lombardy's captivating video, the BoneBlocker controller adeptly translates player movements into precise gamepiece transformations and rotations, brought to life on the towering wall. Lombardy's detailed blog post offers an in-depth account of the BoneBlocker's intricate construction process, providing aspiring makers with invaluable insights into the world of LED display systems.

The BoneBlocker has become a beacon of innovation and entertainment at Coin-Op, captivating patrons with its mesmerizing visuals, intuitive gameplay, and unwavering reliability. A testament to Lombardy's ingenuity and dedication, the wall stands as a glowing tribute to the transformative power of technology and the ever-evolving landscape of interactive entertainment.
