EKS – LED installation. 2014.
LED patterns slowly shift in and out of phase – giving rise to an ever changing light sculpture. Have a look and then scroll down to see how it works. .
Some test pics to see how well it works. Bare in mind that the polgons are created by a rotating line of light which is shaped as it spins. All very striaghtforward trigonometry on paper – but a bit more tricky to get it all working neatly on the Arduino.
And a couple of these.
In this next one, you can see how it works as left the lights on. Pretty!
Video will follow soon.
An idea for the Straight8 super8 competition 2011
The idea is to take a super8 camera and modify it so it can take long exposures controlled by an Arduino.
This camera then films a moving light sculpture which should create nice geometric patterns but in a mesmerising way. Not all flickery like your typical long exposure film.
Here’s the moving light part. It spins around driven by stepper motors and powered via a slip ring. And the rotating part can also move in the xy plane.
The light in the middle is a cold cathode tube. There are masks which can move in and out to shape the light from a point to a line and there’s a colour roll which travels across the light to give it either a single colour, many colours or gradients.
Here are some pics of the set up in the warehouse at reworks. Note that the camera is set up on a long piece of wood in a shopping trolley, so that it points vertically down and can also be tracked back and forth.
