24 x 56 pixel RGB LED screen

my latest project a 24 x 56 pixel RGB LED screen. 8 DMX universes 1344 pixels total. controlled with 2 sandevices e681s and Madrix. there are two panels that are 74" x 20". they are polycarbonate panels made for use in greenhouses. there are air cells in the panels that are the perfect size to slip the LED strips in to. the LED strips were imported from china and have 30 pixels per meter. each DMX univers is 3 strips of 56 leds. there are 12 stips in each panel. i wanted to add an led screen to my inventory but they are way too expensive to buy, so i made my own.
