I got tired of turning a monitoring TV at work on and off every day, so I decided to add an IR receiver and a couple IR LEDs to a Raspberry Pi and let it handle it for me.
Since all the Pi has to do is run a web browser, the GPIO are free to use. I'm using the 3.3V, 5V, and two GPIO pins - one for input from the receiver and one to trigger the transistor to turn on the LEDs.
On the Pi, I'm running the base Raspbian image, and using LIRC to handle sending the power signal to the TV.
