Lean Computing: Lowering power consumption without sacrificing utility

[CurlyMo]

I use remote controllable switches from brands such as http://www.coco-technology.com/en/home/ to pull the power from my whole TV stack. I control these things from my RPi with my own code: https://github.com/CurlyMoo/433.92-Raspberry-Pi/. Never ran in any trouble. However, relays would be fine as well because these CoCo devices essentially work the same.
