Materials: DIODER (RGB), Atmel at90usb162 microcontroller and more.
Description: This is my modified IKEA DIODER. I have replaced the built in microcontroller with another one that support USB. That combined with some open source software makes it possible to control the light from a computer. For example use music and sound to control the light.
Note that I haven’t tested this at all with any operating systems other than Ubuntu.
