With the Raspberry Pi now most famously known as a $30 media PC, it only makes sense that the best uses for the GPIO pins on the Pi are used for an Ambilight.on using the Pi as a uniquely configurable Ambilight with Hyperion and just about any video input imaginable.
This isn’t the first Ambilight clone [Great Scott] has put together, but for
https://www.youtube.com/watch?v=kf2WNVrerck the Ambilight functioned only under Raspbian and not any random HDMI input. The new version solves this by using an HDMI splitter box, feeding into an HDMI to composite converter, and finally into a USB composite capture dongle attached to the Raspi.
With the software in the instructions, the Raspi effectively mirrors the video coming from the video capture dongle. The Pi is running Hyperion (https://github.com/tvdzwan/hyperion/wiki) to control a strip of WS2801 RGB LEDs, making the back of any TV glowey and blinkey.
Since [Great Scott] is using a component video signal as an input, the adapters necessary to have any device work with this Ambilight are readily available. We’d honestly like to see this build working with the old Commodore disk access screen border going nuts, so be sure to send that in (http://hackaday.com/contact-hack-a-day/) if you ever get that working.
