FLASH.IT: The RGB LED climbing wall

rockWallLEDs2

[Chris] and his friends were kicking around ideas for a Burning Man project, and this is the one that stuck: a rock climbing wall with RGB LEDs embedded in the holds. The holds themselves were custom made; the group started by making silicone molds of varying shapes and sizes, then added the electronics and poured in polyurethane resin to create the casting. The boards for these LEDs are equipped with a central hole that pairs up with a peg in the silicone mold. [Chris] also solved an annoying spinning problem by affixing a bolt to the far end of the LED board: once embedded in the polyurethane, the bolt provides resistance that the thin board cannot. The finished holds bolt onto the wall with all their wires neatly sticking out of the back to be hooked up to a central controller.

The Instrucables page suggests a few ways to get the lights working, including grabbing the nearest Arduino and relying on the Neopixel Library from Adafruit. [Chris] went the extra mile for Burning Man, however, designing Arduino-software-compatible controller boards capable of communicating via DMX, which expanded the system from a simple display to one capable of more complex lighting control. Stop by the Github for schematics and PCB layouts, and stick around for a video of the wall after the break. If the thrill-seeking outdoorsman inside you yearns for more, check out WALL-O-TRON from earlier this summer.

WALL-O-TRON, the interactive rock climbing wall

wall

Last April, hackerspaces around the country received a gift from RedBull for their creation challenge. The hackerspace teams were charged with creating, ‘something with LEDs’ and let loose in their workshop for a chance to win a trip to NYC and build some cool stuff. Of course, RedBull couldn’t bring all the teams to the big apple and a few incredible projects were left by the wayside in their home hackerspace.

One such project was the WALL-O-TRON from Team Rabbit-Hole and home base for the Tymkrs. It’s a huge wall embedded with LEDs that turn an ordinary rock climbing wall into a game called WallSweeper – climb a path to the illuminated hold, but don’t touch the ‘hot rock’ or your game is over.

The hand holds are illuminated by over 300 of LEDs connected to a Linux PC. The sign above the wall is controlled by RedBull’s TurBULL Encabulator, and the giant ‘WALL-O-TRON’ letters are huge pieces of foam with five meters of RGB LEDs embedded inside.

A great project with the possibility of being upgraded in the future with more games. Perfect for the rock climbing playground it’s situated in.
