here I share what I have done to create LED back light for my 47′ TV. There are few thing I needed to setup, purchase, build and code.

Things needed:

LED strip – I got WS2812B kmodel with 150 LED (used 114 LED)

Power supply : 5V/40W

Raspberry Pi II – Own it alreday 🙂

Video Grabber

Hyperion Application for RPI2

After some Googling, soldering, assembly and testing. here what I got.
