[Joseph] wrote in to tell us about his Ikea Dioder hack. The Dioder is a lighting system with a silly name from Ikea. It is basically 4 RGB LED bars that are connected to a controller that will cycle their colors in different manners. They aren’t individually addressable, and at $50 aren’t really that great of a deal for people who could build their own. [Joseph] thought that maybe, if the features could be extended, it could be a decent lighting system. He bought it and began searching. Disappointed by the lack of hacks available, he cracked it open and began brainstorming. Ultimately, he decided to interface it with his computer. He can now control it with software, so making an ambilight clone shouldn’t be too difficult.
He does mention that he thought of making 4 independent drivers so that each light bar could be a different color. We agree that this would be the next logical step, possibly even rewiring for individual access to each LED.
