300 DMX linked twinkling stars
The Band, having seen illuminated origami stars whilst touring in Japan, obtained some of the paper based origami pieces with a view to using a large number of them to accompany them on their tour. The initial brief called for 300 active units, several different sizes, each star being on a separate DMX channel.
The Coldplay Stars system uses 24V DC LED tape, this is formed into a circle of the appropriate size and fixed into an Origami paper star. A 5M/16’ lead with a 2.1mm DC plug on the end is attached to the star, this also has a safety clip attached at the top point that clips on to the webbing strap Star String for suspension.
The 2.5M long Star String carries 9 circuits of control for 9 individual stars, outputs are on 2.1mm DC sockets, these are staggered along the length at 300mm intervals, with circuit 1 closest to the input lead. A 4M long input lead is attached to the Star String and connects into the control box via a 12 way multipin connector. The control box has 3 12 way output connectors, each being 9 channels, (one control box has 27 channels). The box is designed to be mounted close to the Star String hanging point and it is fitted with 2 eyes and 2 safety wires so that it can be attached to a variety of objects. The boxes have both mains and DMX in and out connectors on one end so that boxes can be linked together without the need for separate feeds.
