A MythTV Remote Control without LIRC - Power Switch Addon


Overview
This is a little add-on for my MythTV remote control. It adds a hardware power switch feature. This means that you can switch the PC on even if it is completely shut down. There is just one condition, which is that the remote control receiver must have power, supplied through the USB port. On most modern mainboards, this is an option in the BIOS settings. The additional hardware is relatively simple, but the added benefit is substantial, so I think it is worth the effort.
