DIY a Simple and Cool Infrared Receiver By Your Own!
You’re wish to have a universal infrared receiver, which it can be used to control all your electrical appliances, such as the TV, VDR, DVD, Stereo, MP3 or even your computer, without even having to stay at the keyboard all day long? Well, then it’s about time to create your very own Universal infrared receiver!
Basically, the circuit that you’re gonna to use in this project is NOT IrDA compatible. As a result, it will not help you to connect to any cell phones or IrDA devices, and it’s good to control your PC with a standard remote control system.

Furthermore, you can use it for VDR and with the PC that full feature with set top box and has been fully connected to the television. With this unique feature, it’s able to digitally record and replay any satellite television, DVDs and any kind of digital content, such as the MP3 or divx!
Plus, you can easily install many types of different software to control the circuit. If you a Linux user, then you should use Lirc, but if you’re using the Windows, then you can use Winlirc, Girder IR Assistant or uIRC! [link]
