AVR-Stick as an infrared receiver and logger

I have already described a project based on the AVR-Stick hardware. The next thing I wanted to try with that hardware is to create an infrared receiver and logger. In fact I wanted to emulate the dongle I described some time ago. But to emulate it I needed to know the protocol that is used. The easiest way to find out what protocol is used is to analyze signals with an oscilloscope of course but I didn't have one. So first of all I needed to implement a signal logging functionality.

IR control for your router

There are no buttons on my router but very often I need to start some task without accessing the shell. For example I want to switch wireless interface off if I don't need it and the problem here is that I cannot switch it on again wirelessly because wireless interface is off. So I thought I need some kind of a one button USB keyboard or mouse but there is no such thing. Second thought was to use some kind of IR receiver with a remote control. As far as I already have a universal remote control Logitech Harmony 885 I only needed an IR receiver that is supported by Linux. So I bought one manufactured by TechniSat for 15,20Euro with delivery (just google for - TechniSat USB IR receiver)
