Hi, Just a word of warning before anyone who starts this project. If you are using the video grabber with chipset STK1160, you will need to use a Raspberry Pi 2 or above. I have tried using this chip set with a Pi zero and a Pi One B and the lights do not sync properly. They turn off immediately and flash back on for a second, then turn off again for a few seconds. Do NOT use chipset STK1160 with the Pi Zero or Original!
