Introduction: How to Automatically Power Off Electronic Devices
I am always forgetting to turn off my stereo amplifier. I can manage to pause iTunes to stop the music, and the music computer goes to sleep on it's own, but I just can't remember to switch off the amp.
So, I connected the amp to an extra outlet timer and set it to turn off the stereo at times I'm likely to either be away or be asleep. When the timer switches the outlet back on, my Harman/Kardon powers up into stand-by mode. So, when I forget to turn it off, the timer takes care of it for me, and when I want some music, it's ready and waiting in stand-by.
I know this saves only a very little bit of electricity (and if I had bought the timer new and counted its manufacturing costs, this probably consumes more than it saves), but I think it's important to get in the mindset of saving wherever you can, and to set things up so that consumption is reduced automatically.
