Luke McElroy from SALT Nashville Conference in Nashville, TN brings us this versatile use of hanging squares. (Originally posted June 2014)
They used wooden squares wrapped with a cotton material lined with LED Strip Tape in order to create a “LED Wall” that they could project onto, map various patterns into the LED Squares, and most importantly tell a powerful story with. Their heartbeat was to show the conference how a set/stage design could tell a story and evolve as the story of the conference evolved. Using simple LED Strip Tape and a few Chinese DMX Powered controllers, they were able to use MadMapper to convert a very simple high contrast video into a DMX signal and into the lights.
They also made sure the canvas on the front was able to absorb projected images from two 12,000 lumen projectors at front of house. Then they kabuki’d (or dropped free fall style) the entire set on the second day in order to represent our fallen and brokenness. Then the square panels were aligned in a manner to which they could put them in a giant cross and light the squares up one more time.
It cost $2500 to make with all parts, wood, controllers, cloth, and cabling.
Set build details:
- Each square was 1.5″ lumber cut into 4 pieces and staple gunned into a square.
- The used 400 square feet of muslin from a local fabric store.
- The squares were hung using S hooks – all of them were 3″ apart in every direction.
- They lined the squares with LED 5050 “white” LED strip tape.
- They cut each roll, which was 5m, into 3 pieces.
- They lined the LED tape on the inside of each panel effectively turning each panel into a “pixel”
- They made 100 squares and used 96 for the cross.
- The center screen was hand made. It was approximately 5×8′ and it was a non-standard ratio.
- They used some 27 channel DMX LED controllers that they found on eBay.
- They used about 8 controllers to control all the LED.
- They controlled the LEDs using a software app called MadMapper which allowed them to “pixel map” the LED In the panels, IE – each panel could effectively become a pixel of video.
- They also projected onto the panels using three 12k projectors – a Left, Right, and then one on the center screen.
- They used VidVox’s VSMX for all content playback on the surface.
