I've currently been experimenting a little with the embedded linux OS openelec (kodi). I tried to turn it into a full fledged media center which includes emulators and streaming etc. As you all know this is a very power hungry task.
What I've actually been trying to do is look for a way to power the raspberry (which is now connected to the USB port of my TV, this allows me to power on/off the raspberry with just one press on the TV remote).
The USB port only delivers me upto 500mA of power on 5V.
IN SHORT:I was just wondering if it would be possible for me to turn on/off the raspberry pi whenever i turn on/off my tv, and this with a sepperate power adapter. Basically just using the HDMI signal as a power switch for the raspberry.
I hope someone could illuminate me on this topic
Thx in regards
